A) Pub/Sub, Dataflow, BigQuery
B) Cloud SQL, Cloud Functions, Cloud Storage
C) Cloud Spanner, Pub/Sub, App Engine
D) Cloud Run, Firestore, Cloud Functions

Answer: A

Explanation:

Analyzing streaming data for real-time dashboards and alerts requires a combination of services that can reliably ingest, process, and store high-velocity data for immediate analysis. Pub/Sub is a messaging service that allows enterprises to collect streaming events from multiple sources in a scalable and reliable manner, ensuring at-least-once delivery. Cloud SQL and Cloud Spanner, while suitable for transactional workloads, are not optimized for high-throughput streaming analytics. App Engine and Cloud Run provide compute resources but do not handle stream ingestion, processing, and analytics pipelines by themselves. Firestore is a NoSQL database suited for document storage and real-time client synchronization, but lacks capabilities for large-scale streaming analytics. Dataflow is a fully managed data processing service capable of handling batch and streaming data, consuming events from Pub/Sub, performing transformations, aggregations, or enrichment, and outputting results to storage or analytical platforms. BigQuery provides a fully managed data warehouse for storing processed streaming data, enabling fast SQL-based querying, dashboards, and alerting through tools such as Looker, Data Studio, or custom applications. IAM ensures secure access, while logging and monitoring provide visibility into pipeline performance, message processing, and query execution. Dataflow supports windowing, triggers, and late data handling, ensuring accurate computation even when data arrives out of order, which is critical for real-time dashboards. Horizontal scaling allows handling of massive data streams, and checkpointing ensures fault tolerance and recovery from failures. Enterprises can implement alerting for anomalies, thresholds, or events based on processed data, enabling timely operational or business actions. Integration between Pub/Sub, Dataflow, and BigQuery provides a decoupled architecture, allowing producers, consumers, and processing layers to scale independently while maintaining reliability. Dataflow pipelines can enrich, aggregate, or filter streaming events before storing them in BigQuery, optimizing query performance for dashboards. Monitoring dashboards provide near real-time insights into system health, message latency, processing times, and query metrics. This architecture supports streaming analytics, ETL pipelines, machine learning, and operational intelligence, enabling enterprises to act on data as it is generated. Cost optimization is achieved through serverless scaling, minimized resource usage, and efficient query patterns. By leveraging Pub/Sub, Dataflow, and BigQuery, organizations gain a robust, scalable, and reliable streaming analytics solution capable of powering real-time dashboards, alerts, and insights. This combination ensures high throughput, low latency, accurate processing, operational simplicity, and integration with visualization tools for actionable analytics in real time. It allows enterprises to respond rapidly to events, monitor operational metrics, and gain business insights without managing infrastructure or pipelines manually.
