Question 46

A company wants to schedule a recurring data processing job that reads files from Cloud Storage, transforms them, and writes the results back to Cloud Storage. Which Google Cloud service combination is most appropriate?

A) Cloud Scheduler triggering a Cloud Dataflow job
B) Cloud Functions alone
C) App Engine cron jobs only
D) Cloud SQL scheduled queries

Answer: A

Explanation:

Scheduling recurring, large-scale data processing workflows requires both a scheduling mechanism and a data processing platform capable of handling large volumes of data efficiently. Cloud Scheduler is a fully managed cron service that allows organizations to trigger jobs at regular intervals. It can invoke HTTP endpoints, publish messages to Pub/Sub, or trigger serverless functions and data processing jobs. For large-scale, batch-oriented, or streaming data processing tasks, Cloud Dataflow is ideal. Dataflow is a fully managed, serverless service for executing Apache Beam pipelines, allowing transformation, aggregation, and enrichment of data. Combining Cloud Scheduler and Cloud Dataflow provides an automated, scalable, and reliable solution for recurring data processing tasks. Scheduler ensures the job runs on schedule, while Dataflow handles the heavy lifting of reading input from Cloud Storage, transforming it according to the pipeline logic, and writing the output back to Cloud Storage. The combination reduces operational overhead, supports monitoring and logging, and scales automatically based on workload.

Using Cloud Functions alone is insufficient for recurring, large-scale data processing tasks. While Cloud Functions can be triggered by events, it is not optimized for complex, large-scale transformations. Processing large files or performing batch operations could result in execution time limits being exceeded or memory constraints, leading to failures. Cloud Functions works best for event-driven, small-scale operations rather than full-scale ETL workflows.

App Engine cron jobs can schedule tasks within the App Engine environment, but they lack native integration with scalable data processing pipelines like Dataflow. While cron jobs can trigger HTTP endpoints or services, executing large-scale data transformations through App Engine requires building custom pipelines, managing scaling, and handling failures manually. This introduces complexity and reduces reliability compared to using Cloud Scheduler and Dataflow, which are designed for scheduled, high-volume data processing.

Cloud SQL scheduled queries allow the execution of SQL queries at scheduled intervals within the database. While suitable for relational data processing, Cloud SQL is not optimized for processing large files in Cloud Storage or performing complex transformations. It also does not scale automatically for large workloads, and scheduling queries alone does not provide the full capabilities required for batch ETL or pipeline execution.

The correct solution is to combine Cloud Scheduler with Cloud Dataflow. Scheduler ensures the timely execution of the job, while Dataflow provides the scalability and processing capabilities required for transforming large files. Dataflow pipelines can include multiple steps, conditional transformations, joins, aggregations, and integration with other Google Cloud services. Logging, monitoring, and error handling are built in, providing operational visibility. Using this combination, organizations can implement automated, reliable, and scalable data processing pipelines that read from Cloud Storage, perform transformations, and write results back efficiently. This architecture reduces operational complexity, ensures performance and scalability, and supports recurring processing tasks for large volumes of data. By leveraging managed services, teams can focus on developing the pipeline logic rather than infrastructure management, enabling cost-effective and robust recurring workflows.

Question 47

A company wants to create a private, internal API that can be accessed only by services running in their VPC network. Which Google Cloud service should be used?

A) API Gateway with VPC Service Controls
B) Cloud Functions with public HTTP trigger
C) App Engine Standard Environment without restrictions
D) Cloud SQL

Answer: A

Explanation:

Creating a private internal API requires mechanisms to enforce network-based access controls while supporting service-to-service communication within the VPC. API Gateway provides a managed platform for creating, securing, and monitoring APIs. When combined with VPC Service Controls, administrators can ensure that API access is restricted to requests originating from specified networks or trusted service accounts within the VPC. VPC Service Controls create a security perimeter that prevents external access and data exfiltration, enforcing internal access policies. API Gateway integrates with IAM for authentication, supports rate limiting, logging, and monitoring, and provides features such as API key validation and JWT token validation. This combination ensures the API is only accessible from within the internal network and adheres to security and compliance requirements.

Cloud Functions with a public HTTP trigger expose the endpoint to the internet. While authentication mechanisms can be applied, the function remains publicly accessible, increasing security risk. There is no built-in mechanism to enforce that only traffic from the internal VPC can reach the API. This configuration would require additional firewall rules, network proxies, or custom authentication, increasing operational complexity.

App Engine Standard Environment, without restriction,s is publicly accessible by default. Deploying APIs on App Engine without VPC Service Controls or private networking exposes endpoints to the internet. Without additional configuration for access control, the API would not meet the requirement for private, internal-only access. Traffic could originate from any source, making it unsuitable for internal VPC-only APIs.

Cloud SQL is a relational database service, not an API hosting platform. While it can restrict connections to specific networks, it does not provide API routing, authentication, monitoring, or traffic management capabilities. Using Cloud SQL alone does not meet the requirement to serve a private internal API for VPC-based access.

The recommended solution is to deploy API Gateway with VPC Service Controls. API Gateway provides a managed, scalable, and secure API layer, while VPC Service Controls enforce that only requests originating from the VPC network or trusted sources can access the API. IAM integration ensures that only authorized service accounts can call the endpoints, while logging and monitoring provide visibility into usage patterns. Traffic policies, quotas, and rate limiting can be configured to protect internal services. This architecture allows teams to create secure, private APIs without managing underlying infrastructure or exposing endpoints publicly. Using API Gateway with VPC Service Controls simplifies operational management, provides strong security guarantees, and ensures compliance with internal network access policies. It is an enterprise-grade solution for hosting private APIs while maintaining isolation and observability. By leveraging managed services, organizations can deploy scalable, maintainable internal APIs with minimal operational complexity and strong security enforcement.

Question 48

A team needs to deploy a containerized web application that automatically scales, supports zero-downtime deployments, and requires minimal operational management. Which Google Cloud service should be used?

A) Cloud Run
B) Compute Engine
C) Kubernetes Engine with manual scaling
D) App Engine Flexible Environment

Answer: A

Explanation:

Deploying a containerized web application that automatically scales and requires minimal operational management is best achieved with Cloud Run. Cloud Run is a fully managed, serverless platform that runs containers in response to HTTP requests. It supports automatic scaling from zero to handle variable workloads, ensuring cost efficiency and responsiveness. Cloud Run allows deploying multiple revisions of a container, enabling zero-downtime updates and traffic splitting for canary or staged deployments. Security, networking, monitoring, and logging are fully managed, reducing operational complexity and allowing developers to focus on application logic rather than infrastructure management. Cloud Run abstracts away cluster management, node provisioning, and patching, providing a fully managed environment suitable for stateless web applications.

Compute Engine provides virtual machines for full control over infrastructure. While it can run containers, scaling, load balancing, and zero-downtime deployment must be managed manually. This increases operational complexity and requires continuous monitoring, configuration, and maintenance, making it less suitable for applications requiring minimal operational management.

Kubernetes Engine provides full container orchestration and scaling capabilities. While powerful, manual scaling and cluster management are required if autoscaling is not configured. Rolling updates, traffic management, and monitoring require additional configuration and operational expertise. Managing clusters, nodes, and networking increases complexity compared to a fully serverless solution.

App Engine Flexible Environment supports containerized applications with managed infrastructure and autoscaling. While it provides zero-downtime deployments, scaling is less granular, and developers have to consider instance classes and regional distribution. Cloud Run offers more straightforward container deployment without managing runtime instances, making it better for serverless, stateless workloads that require minimal operational management.

Cloud Run is the correct solution because it provides automatic scaling, zero-downtime deployments, multiple revisions, and serverless operation. It abstracts infrastructure management, integrates with monitoring and logging, and allows secure networking and authentication. Developers can focus entirely on containerized application logic, with the platform handling scaling, load balancing, and deployment operations. This ensures highly available, resilient, and cost-efficient application deployment while minimizing operational overhead. Cloud Run is ideal for stateless web applications requiring rapid deployment, automatic scaling, and simplified operational management. Its fully managed serverless architecture supports modern containerized applications and provides observability, security, and traffic control without complex infrastructure management, fulfilling all the requirements effectively.

Question 49

A company needs to process streaming IoT data in real time to detect anomalies and trigger alerts. Which Google Cloud service is most suitable for this purpose?

A) Cloud Dataflow
B) Cloud Storage
C) Cloud SQL
D) App Engine Standard Environment

Answer: A

Explanation:

Real-time processing of streaming IoT data requires a system capable of ingesting high volumes of continuously arriving data, transforming it, and detecting anomalies in near real time. Cloud Dataflow is a fully managed, serverless data processing service designed for both batch and stream processing. Using Apache Beam pipelines, Dataflow can process streaming data from Pub/Sub or other sources, apply transformations, detect patterns, and trigger actions based on defined logic. Dataflow automatically scales to handle spikes in incoming data and manages the underlying infrastructure, ensuring minimal operational overhead. It provides fault tolerance, checkpointing, and exactly-once processing semantics, which are essential for reliable anomaly detection. Integration with Cloud Monitoring, Cloud Logging, and Pub/Sub allows teams to visualize pipeline performance, log events, and send alerts when anomalies are detected, creating a complete, end-to-end real-time data processing solution.

Cloud Storage is a durable object storage service and cannot process data in real time. While streaming data could be written to Cloud Storage, analysis would require batch processing or external tools, resulting in significant latency. Cloud Storage is suitable for archiving or batch processing, but does not provide the real-time capabilities necessary for detecting anomalies and triggering immediate alerts.

Cloud SQL is a relational database designed for transactional workloads and structured data storage. It is not optimized for high-velocity streaming data and cannot natively process real-time data for anomaly detection. Using Cloud SQL for streaming IoT data would require intermediate services to ingest, transform, and analyze data, introducing latency and operational complexity, which contradicts the requirement for real-time processing.

App Engine Standard Environment is a serverless platform for deploying web application,s butit  is not designed for real-time stream processing. While it can host services that process events, it does not provide native support for continuous streaming pipelines, fault tolerance for high-volume streams, or exactly-once semantics. Scaling App Engine alone cannot handle continuous, high-throughput data processing for anomaly detection.

Cloud Dataflow is the correct solution because it provides a managed, scalable, and reliable platform for processing streaming IoT data in real time. It allows developers to define processing pipelines that read from Pub/Sub, apply transformations, filter anomalies, and trigger alerts or downstream processes. Dataflow automatically manages parallelism, scaling, and resource allocation based on workload demands, ensuring consistent performance. Its integration with monitoring, logging, and Pub/Sub provides observability and operational control, enabling teams to detect issues early and respond proactively. By leveraging Dataflow, organizations can implement real-time anomaly detection with minimal operational overhead, high reliability, and scalability. Dataflow also supports windowing and event-time processing, which are essential for analyzing time-series IoT data accurately. This ensures precise detection of patterns and anomalies, providing actionable insights immediately. The service abstracts infrastructure management, allowing developers to focus entirely on pipeline logic while maintaining cost efficiency and performance. Using Dataflow aligns with best practices for event-driven, real-time data processing and meets enterprise requirements for high availability, fault tolerance, and automated alerting for streaming IoT workloads.

A) Cloud VPN with HA VPN
B) Cloud Storage
C) App Engine Standard Environment
D) Cloud Functions

Answer: A

Explanation:

Establishing a secure connection between on-premises networks and Google Cloud requires encrypted communication, high availability, and minimal latency. Cloud VPN provides an IPsec-based encrypted tunnel between the on-premises environment and Google Cloud, ensuring that data in transit is protected. High Availability (H A) VPN offers active-active VPN tunnels across multiple Google Cloud regions, providing redundancy and failover in case of a tunnel or endpoint failure. This setup ensures continuous connectivity, load balancing between tunnels, and improved resiliency for mission-critical applications. HA VPN supports BGP (Border Gateway Protocol) for dynamic routing, simplifying route management between the on-premises network and Google Cloud Virtual Private Cloud (VPC) networks. This approach provides secure, highly available, and low-latency connectivity suitable for hybrid architectures that require seamless access to cloud services while maintaining on-premises network integration.

Cloud Storage is a managed object storage service for storing files, backups, and large datasets. While it can facilitate data transfer, it does not provide network connectivity, encryption for live traffic, or high-availability links between on-premises networks and Google Cloud. Using Cloud Storage alone does not address requirements for secure, low-latency, or continuously available hybrid network connections.

App Engine Standard Environment is a platform for hosting applications. It does not provide connectivity between on-premises networks and cloud infrastructure. Deploying applications on App Engine without a secure network connection does not meet requirements for integrating on-premises workloads with Google Cloud networks.

Cloud Functions is a serverless compute service for running code in response to events. It cannot establish persistent, secure connections between on-premises networks and Google Cloud. While Cloud Functions can interact with cloud services once network connectivity exists, it does not provide the infrastructure or routing required for hybrid networking.

Cloud VPN with HA VPN is the recommended solution because it provides secure, encrypted connectivity with redundancy for high availability. Active-active tunnels ensure that traffic can continue flowing even if one tunnel fails, reducing downtime. BGP support allows dynamic routing updates, minimizing manual configuration and ensuring optimal path selection. The service supports multiple tunnels, load balancing, and monitoring, allowing administrators to maintain performance and visibility. Using HA VPN, organizations can integrate on-premises applications with cloud resources such as Compute Engine, Cloud SQL, or Kubernetes Engine, providing seamless hybrid operations. HA VPN also reduces latency by optimizing routes, supporting resilient communication between environments. By implementing Cloud VPN with HA VPN, companies gain a reliable, secure, and scalable solution for hybrid connectivity, ensuring business continuity, encrypted communication, and operational efficiency across cloud and on-premises environments. This solution addresses the requirement for secure, highly available, low-latency hybrid network connections while minimizing operational complexity and maintaining enterprise-grade reliability.

Question 51

A company needs to deploy a web application that serves global users with low latency, caching static content, and automatically distributing traffic to multiple regions. Which Google Cloud service should be used?

A) Cloud CDN
B) Cloud SQL
C) Cloud Functions
D) App Engine Standard Environment

Answer: A

Explanation:

Serving a web application to a global audience with low latency requires caching content at edge locations and distributing traffic efficiently across multiple regions. Cloud CDN is a fully managed content delivery network that caches static and dynamic content at Google’s global edge points of presence, reducing latency by serving content closer to users. Cloud CDN integrates with backend services such as Compute Engine, Kubernetes Engine, Cloud Storage, and App Engine, providing scalable distribution of content. It supports caching policies, cache invalidation, logging, and monitoring, allowing teams to optimize performance, reduce load on origin servers, and improve user experience. Traffic is automatically routed to the nearest edge location, ensuring fast delivery and high availability even during regional outages or traffic spikes. Cloud CDN also provides HTTPS support, DDoS protection, and integration with Google’s global load balancing for seamless traffic management across multiple backend regions.

Cloud SQL is a managed relational database service and does not provide caching or traffic distribution. While essential for storing structured data, it cannot serve static content, reduce latency globally, or act as a CDN for web applications. Using Cloud SQL alone would not meet performance and global delivery requirements.

Cloud Functions is a serverless compute platform that executes code in response to events. While it can serve dynamic content, it does not provide global caching or optimized delivery through edge locations. Content served from Cloud Functions still relies on origin compute resources, which may increase latency for globally distributed users. Additional mechanisms would be required to achieve CDN-like behavior.

App Engine Standard Environment hosts web applications with scaling capabilities but does not provide global caching at edge locations. Applications running on App Engine still route traffic to central regions, and static content must be cached or managed separately to optimize latency. It cannot achieve the low-latency global content distribution that Cloud CDN provides natively.

Cloud CDN is the correct solution because it caches static content globally, reduces latency for users, and distributes traffic to multiple regions automatically. Integration with Google’s global load balancing ensures optimal routing, fault tolerance, and high availability. Cloud CDN supports advanced features such as cache invalidation, signed URLs for secure content, custom caching policies, and logging for monitoring performance and usage. By leveraging Cloud CDN, organizations can improve user experience, reduce load on backend infrastructure, and scale efficiently for global traffic. This approach ensures low-latency delivery, high availability, and operational simplicity for globally distributed web applications. Using Cloud CDN aligns with best practices for serving static and dynamic content efficiently, providing enterprise-grade content delivery with minimal operational management.

Question 52

Flexible Environment supports persistent storage integration, VPC connectivity, and logging/monitoring tools, which are critical for enterprise applications. Its zero-downtime deployment capabilities also enable updates without interrupting service, making it suitable for production workloads migrating from on-premises environments.

Compute Engine with a single VM does not provide automatic scaling or high availability by default. While the VM can host the legacy application with minimal changes, maintaining uptime and performance under varying loads would require manual scaling, failover configurations, and monitoring. This introduces operational complexity and potential single points of failure, making it less suitable for highly available cloud-native workloads. Managing patching, backups, and security also falls entirely on the user, increasing administrative overhead.

Cloud Functions is designed for event-driven workloads and short-lived, stateless functions. Legacy applications, especially monolithic ones, cannot be directly deployed on Cloud Functions without significant code refactoring. It does not support persistent connections, long-running processes, or multi-threaded applications. Using Cloud Functions for legacy applications would require major architectural changes and does not inherently provide high availability or automatic scaling for continuous workloads.

Cloud Storage is an object storage service intended for storing files and unstructured data. It does not provide compute or application hosting capabilities. While the legacy application could theoretically store assets in Cloud Storage, it cannot run as an application, making Cloud Storage unsuitable for migrating legacy workloads to the cloud.

App Engine Flexible Environment is the correct solution because it provides a managed, scalable environment for containerized applications with minimal refactoring. Developers can deploy existing application code with minor modifications, benefit from autoscaling, and leverage built-in high availability. Health checks and rolling updates reduce downtime and ensure operational reliability. The service integrates with monitoring, logging, and networking services, simplifying maintenance and providing operational visibility. By using App Engine Flexible Environment, organizations can migrate legacy applications efficiently, maintain consistent performance under variable traffic, and reduce operational overhead.

Streaming inserts and batch loading enable near real-time analytics, while integration with tools like Data Studio, Looker, and Python libraries facilitates advanced analysis and visualization. Security, auditing, and compliance are managed via IAM, encryption, and logging integration, making it suitable for enterprise analytics workloads.

Cloud Storage is designed for object storage and can store structured or unstructured data at a large scale. However, it is not optimized for analytical queries or high-speed SQL operations. Performing analytics would require exporting the data to a separate system or building custom processing pipelines, introducing latency and operational complexity. Cloud Storage serves well as a raw storage layer but does not provide the performance or SQL-based querying capabilities needed for petabyte-scale analytics.

Cloud SQL is a managed relational database for transactional workloads. It supports SQL queries, indexing, and transactions, but it is not optimized for petabyte-scale analytical workloads. Large-scale aggregations and complex joins across massive datasets would be slow and costly, and scaling beyond tens or hundreds of terabytes is challenging. Cloud SQL is suitable for OLTP (online transactional processing) but not OLAP (online analytical processing) workloads.

Firestore is a NoSQL document database designed for high-availability, low-latency operational workloads. It is optimized for storing and retrieving structured or semi-structured documents in real time. While excellent for operational data and web/mobile applications, it is not suitable for analytical workloads requiring complex SQL queries or processing petabytes of data. Query performance for analytical patterns is limited, and aggregations across large datasets are inefficient.

BigQuery is the correct solution because it is optimized for storing and querying large volumes of analytical data efficiently. Its serverless architecture removes the need for infrastructure management, and its query engine is optimized for distributed, parallel processing. BigQuery supports advanced analytical operations, including joins, aggregations, window functions, and user-defined functions. Data can be ingested from Cloud Storage, streaming pipelines, or external sources. Partitioning and clustering further optimize query performance and cost efficiency. IAM policies, audit logging, and encryption ensure secure access and compliance. BigQuery also provides seamless integration with machine learning tools like BigQuery ML, enabling predictive analytics directly within the platform. Organizations can execute fast queries on massive datasets, gain insights in near real time, and scale effortlessly as data grows. By leveraging BigQuery, teams can focus on analytics and decision-making rather than managing infrastructure, providing enterprise-grade performance, scalability, and operational simplicity for large-scale analytical workloads.

Security is maintained through device registration tokens and authentication using Firebase credentials. The platform scales automatically to millions of devices, eliminating the need for infrastructure management. Developers can schedule, personalize, and segment notifications for targeted delivery, improving engagement and operational efficiency.

Cloud Functions is a serverless compute platform that executes code in response to events. While it can trigger notifications or messages programmatically, it is not designed to handle direct communication with millions of devices. Using Cloud Functions alone would require integrating with a messaging system like FCM and managing retries, device tokens, and delivery, increasing operational complexity. It cannot natively provide device-level messaging at scale.

Cloud SQL is a managed relational database service. While it can store user data, preferences, and notification metadata, it cannot send notifications directly to mobile devices. Implementing large-scale messaging through Cloud SQL would require additional components for message delivery and would not meet scalability or real-time requirements.

App Engine Standard Environment hosts applications but does not provide a built-in service for sending notifications to mobile devices. While it could serve as a backend for generating notifications, the delivery to millions of devices would still require integration with a service like FCM. Handling retries, device registration, and scaling manually would be operationally intensive.

Firebase Cloud Messaging is the correct solution because it provides a managed, scalable platform for secure delivery of notifications to millions of devices. It supports real-time and scheduled messaging, user segmentation, and analytics integration to measure delivery and engagement. FCM automatically scales to handle large volumes, ensures reliable delivery, and provides secure token-based authentication. It integrates seamlessly with Firebase and Google Cloud services for building backend workflows, triggers, and analytics dashboards. By using FCM, organizations can focus on content creation and user engagement rather than infrastructure management.

Observability through telemetry, metrics, and logging provides insight into service behavior, performance, and failures. Anthos Service Mesh automates policy enforcement, reducing the operational burden of managing microservice security, routing, and scaling while enabling high availability and seamless communication between services.

Cloud Functions with HTTP triggers allow serverless functions to respond to web requests, providing an event-driven architecture. While functions can call one another via HTTP, service discovery is manual, and secure service-to-service communication must be implemented with additional mechanisms. Load balancing across functions is limited, and maintaining complex microservice interactions requires extra orchestration. Cloud Functions is best suited for event-driven, stateless workloads, not a complete microservices communication framework.

Cloud Storage is a managed object storage service for storing files and unstructured data. It does not provide compute, service discovery, or load balancing capabilities. Using Cloud Storage for microservice communication would require custom middleware and complex integrations, which iwould introducesignificant operational overhead and would not meetthe  requirements for secure service-to-service communication.

App Engine Standard Environment hosts applications and provides scaling and routing within the platform. While multiple services can communicate over HTTP, service discovery and advanced traffic management, like retries, circuit breaking, and traffic splittin,g are limited. Security between services must be handled manually using authentication mechanisms, which increases complexity. It is less suitable for microservices requiring secure, automated communication and centralized observability.

Anthos Service Mesh is the recommended solution because it provides a managed framework for secure, observable, and scalable microservices communication. It enforces mutual TLS encryption, manages service discovery, handles traffic routing, and provides observability for metrics, logs, and traces. It supports advanced deployment patterns like canary releases, traffic splitting, and rolling updates. Policies for security, routing, and rate limiting can be centrally managed, reducing manual configuration. With automatic load balancing and fault tolerance, services remain highly available and resilient to failures.

A company wants to build a serverless API that automatically scales and integrates with authentication, logging, and monitoring. Which Google Cloud service should be used?

A) Cloud Run
B) Compute Engine
C) Kubernetes Engine
D) Cloud Storage

Answer: A

Explanation:

Building a serverless API that automatically scales, integrates with authentication, logging, and monitoring requires a platform designed for containerized workloads with minimal operational management. Cloud Run is a fully managed, serverless platform that executes containers in response to HTTP requests or events. It automatically scales from zero to handle spikes in traffic and scales back down when idle, optimizing cost efficiency. Cloud Run integrates with IAM for authentication, allowing granular access control for APIs. Logging and monitoring are built in, providing operational visibility through Cloud Logging and Cloud Monitoring. Cloud Run also supports multiple revisions for zero-downtime deployments and traffic splitting for canary releases or staged rollouts, enabling safe continuous delivery. It abstracts infrastructure management, allowing developers to focus on writing application logic rather than managing servers, clusters, or load balancers.

Compute Engine provides virtual machines for hosting applications. While it can run containerized APIs, scaling must be configured manually through managed instance groups or load balancers. Authentication, logging, and monitoring require additional configuration and maintenance. Using Compute Engine increases operational complexity compared to a serverless platform, making it less suitable for an automatically scaling API.

Kubernetes Engine provides container orchestration with fine-grained control over deployments, scaling, and service management. While it supports serverless-style workloads with Cloud Run on GKE, using Kubernetes Engine directly requires managing clusters, nodes, and scaling policies. Configuring authentication, monitoring, and logging is more complex compared to Cloud Run, which provides these features out of the box. Manual management adds operational overhead.

Cloud Storage is an object storage service and cannot host APIs or provide serverless execution. While it can store data or serve static content, it does not execute code or respond to HTTP requests as an API. Cloud Storage alone does not meet requirements for scalable, serverless API deployment.

Cloud Run is the correct solution because it provides a fully managed, serverless platform for running containerized APIs. Automatic scaling ensures that traffic spikes are handled efficiently without manual intervention, while idle workloads incur no cost. Integration with IAM enables secure authentication and authorization for API endpoints. Logging and monitoring provide insights into performance, usage patterns, and errors. Zero-downtime deployments and traffic splitting support safe updates and canary testing. Cloud Run abstracts the infrastructure, eliminating the need for manual server or cluster management, and allows developers to focus on API logic and business functionality. By leveraging Cloud Run, organizations can deploy secure, reliable, scalable, and observable serverless APIs efficiently, reducing operational complexity while maintaining high performance and availability. Its seamless integration with other Google Cloud services ensures end-to-end operational excellence and secure API delivery.

Question 58

A company wants to deploy a Kubernetes application across multiple regions with automatic failover and load balancing. Which Google Cloud service should be used?

A) Google Kubernetes Engine with multi-regional clusters
B) Compute Engine single VM in one region
C) Cloud Functions
D) App Engine Standard Environment

Answer: A

Explanation:

Deploying a Kubernetes application across multiple regions requires a platform that provides container orchestration, automated scaling, and cross-region failover capabilities. Google Kubernetes Engine (GKE) with multi-regional clusters allows organizations to deploy containerized applications across several regions, providing high availability and fault tolerance. GKE handles cluster management, node provisioning, and automatic scaling of pods, ensuring that workloads are balanced across regions. Multi-regional clusters enable applications to remain available even if an entire region experiences an outage, automatically routing traffic to healthy regions. Integration with global load balancing provides seamless distribution of requests across multiple clusters, optimizing performance and minimizing latency for end users. GKE also supports health checks, rolling updates, self-healing pods, and monitoring through Cloud Monitoring and Logging, giving teams full visibility into application performance and reliability. Security features, including IAM and network policies, ensure controlled access and secure communication between services.

Compute Engine with a single VM in one region provides basic compute resources but lacks automated scaling, high availability, and cross-region failover. Running a single VM creates a single point of failure, making it unsuitable for production workloads requiring continuous availability and global reach. Scaling would require manual configuration and management of additional instances and load balancers, significantly increasing operational complexity. Ensuring fault tolerance across regions with a single VM is not feasible.

Cloud Functions is a serverless compute platform that executes event-driven functions. While it can scale automatically and handle workloads triggered by events, it is not designed for hosting multi-regional containerized applications with complex orchestration requirements. Functions do not provide built-in multi-region clustering, load balancing for stateful services, or advanced deployment strategies like canary releases or rolling updates. Using Cloud Functions alone does not meet the requirements for high-availability, multi-region container workloads.

App Engine Standard Environment provides managed scaling and load balancing for stateless applications, but does not support containerized workloads with the flexibility of Kubernetes. While App Engine handles scaling and routing within a region, deploying across multiple regions requires additional configuration and does not offer the fine-grained orchestration and automated failover that GKE provides. Complex multi-service applications with dependencies would be difficult to manage without container orchestration features.

GKE with multi-regional clusters is the correct solution because it provides a fully managed, highly available platform for deploying containerized applications globally. Multi-regional deployments ensure continuity during regional outages, and pods are automatically rescheduled on healthy nodes to maintain service availability. Global load balancing distributes traffic efficiently across regions, optimizing latency and performance for end users. Rolling updates and canary deployments allow zero-downtime updates, and self-healing ensures pods are restarted automatically when failures occur. Metrics, logging, and monitoring integration provide operational visibility, enabling proactive management of application performance. GKE abstracts infrastructure management while supporting advanced container orchestration features, making it suitable for enterprise-scale deployments. By leveraging multi-regional clusters, organizations achieve scalability, resilience, and global availability, fulfilling requirements for high-availability Kubernetes applications. Teams benefit from automated resource management, fault tolerance, and integrated security policies, ensuring operational efficiency and reliable service delivery. This architecture supports critical workloads while minimizing manual intervention and reducing the risk of downtime, providing a robust, enterprise-grade solution for containerized applications that span multiple regions.

Question 59

A company needs a cost-effective way to run small, event-driven workloads that do not always need to be on. Which Google Cloud service should be used?

A) Cloud Functions
B) Compute Engine
C) App Engine Flexible Environment
D) Cloud SQL

Answer: A

Explanation:

Event-driven workloads that are infrequent and do not require continuous availability are best suited for serverless execution platforms that scale automatically and charge based on actual usage. Cloud Functions is a serverless compute service that executes code in response to events, such as changes to Cloud Storage, Pub/Sub messages, HTTP requests, or other triggers. Cloud Functions is cost-effective because billing is based on actual compute time and resource consumption, meaning organizations pay only when the function executes. It automatically scales from zero to handle bursts of traffic and scales back down to zero when idle, reducing unnecessary costs. Cloud Functions abstracts infrastructure management, including server provisioning, patching, and scaling, allowing developers to focus solely on the application logic. Logging, monitoring, and integration with IAM for authentication and security are bbuilt in providing operational visibility and control.

Compute Engine provides virtual machines for general-purpose computing. While it can run event-driven workloads, a VM is typically always on unless managed through complex auto-scaling policies. Running infrequent tasks on a constantly running VM incurs unnecessary costs because billing is based on uptime, not execution. Compute Engine requires manual configuration of scaling, triggers, and monitoring, increasing operational complexity compared to serverless solutions.

App Engine Flexible Environment is designed for running containerized applications with managed infrastructure and scaling. While it supports autoscaling, it is not as cost-effective for small, intermittent workloads because instances are typically allocated and maintained even during low traffic periods. A flex environment may require additional configuration for event-driven triggers and is more suitable for continuous applications or web services rather than sporadic event-driven execution.

Cloud SQL is a managed relational database and does not execute code in response to events. While it can store and serve data, it cannot process workloads or run event-driven functions. Using Cloud SQL alone to execute tasks is not feasible, as it provides no mechanism for serverless execution, scaling, or billing based on actual workload consumption.

Cloud Functions is the correct solution because it provides a fully managed, event-driven, serverless platform with automatic scaling and cost-effective billing. It supports a wide variety of triggers, including HTTP, Pub/Sub, Cloud Storage, and Firebase events, enabling seamless integration with other services. Security, logging, and monitoring are built in, reducing operational overhead. Functions scale automatically in response to demand, ensuring that workloads are processed efficiently without over-provisioning resources. By leveraging Cloud Functions, organizations achieve operational simplicity, cost savings, and flexibility, allowing developers to focus on writing code while the platform manages infrastructure, scaling, and execution. This architecture is ideal for sporadic, small-scale tasks, eliminating idle resource costs, ensuring reliable execution, and providing a serverless environment that can handle variable workloads effectively. Cloud Functions delivers the operational efficiency, cost-effectiveness, and scalability required for event-driven workloads that do not need to be always on, making it the optimal choice for organizations looking to minimize costs while maintaining reliable processing.

Question 60

A company wants to run analytics on log data stored in Cloud Storage without managing infrastructure. Which Google Cloud service should be used?

A) BigQuery
B) Cloud SQL
C) Compute Engine
D) App Engine Standard Environment

Answer: A

Explanation:

Running analytics on log data stored in Cloud Storage requires a platform optimized for large-scale, query-based analysis without infrastructure management. BigQuery is a fully managed, serverless data warehouse designed for analyzing massive datasets efficiently using SQL. Logs stored in Cloud Storage can be loaded into BigQuery or queried directly using external tables, enabling rapid analysis without provisioning servers. BigQuery handles storage, scaling, query optimization, and parallel processing automatically, allowing teams to run complex queries over terabytes or petabytes of data with low latency. Serverless architecture eliminates operational overhead, while integrations with visualization tools like Looker and Data Studio enable reporting and dashboarding. Security is provided via IAM policies, encryption, and audit logging, ensuring compliance and controlled access.

Cloud SQL is a managed relational database optimized for transactional workloads. While it can perform queries on structured data, it is not suitable for analyzing massive log datasets at scale. Query performance would degrade significantly with large volumes, and scaling to petabyte-scale logs is not feasible. Cloud SQL also requires managing storage and compute resources, increasing operational overhead.

Compute Engine provides virtual machines that can run custom analytics pipelines. While flexible, using VMs requires manual provisioning, scaling, and management, including monitoring, patching, and data orchestration. Running queries on large datasets stored in Cloud Storage would involve additional setup for data ingestion, distributed processing, and storage management, making it less practical for serverless, on-demand analytics.

App Engine Standard Environment hosts applications with managed scaling but does not provide a data warehouse or query engine for large-scale log analytics. While an application could read logs and process them programmatically, this approach would be inefficient, slow, and operationally complex compared to using a service designed for analytics.

BigQuery is the correct solution because it provides serverless, scalable, and highly optimized analytics for logs stored in Cloud Storage. It supports SQL queries, joins, aggregations, and window functions, enabling detailed analysis of large log datasets without infrastructure management. BigQuery can handle both batch and near-real-time analytics with high performance and low latency. Its integration with Cloud Storage allows external tables for direct querying, avoiding unnecessary data movement. IAM, logging, and encryption provide secure, auditable access to sensitive log data. By leveraging BigQuery, organizations can analyze logs at scale, generate insights, create dashboards, and detect anomalies efficiently. The serverless architecture reduces operational burden, supports rapid scaling, and minimizes costs, as billing is based on storage and query execution. This solution meets enterprise requirements for analyzing large datasets efficiently, reliably, and securely without managing servers, ensuring operational efficiency and actionable insights from log data.
