Its fully managed nature ensures that operational tasks such as patching, monitoring, and scaling are handled automatically, reducing administrative overhead and improving reliability.
For these reasons, Azure SQL Database is the correct choice for workloads that require reliable, fully managed relational database capabilities. It combines the benefits of traditional relational database features with the advantages of a cloud-managed service, providing performance, scalability, and operational simplicity. By leveraging Azure SQL Database, organizations can ensure data integrity, achieve high availability, and focus on building applications without the complexities of infrastructure management.
Question 210
Which Azure service improves application performance by caching frequently accessed data in memory?
A) Azure Cache for Redis
B) Azure Blob Storage
C) Azure SQL Database
D) Azure Functions
Answer: A) Azure Cache for Redis
Explanation:
Azure Blob Storage stores unstructured data but does not provide in-memory caching. Azure SQL Database persists relational data but is not optimized for caching. Azure Functions executes code but does not include caching capabilities. Azure Cache for Redis is a fully managed, in-memory caching service designed to store frequently accessed data to reduce latency and improve application performance. It supports high-throughput workloads, session storage, and real-time analytics. Azure Cache for Redis is the correct choice because it enhances application responsiveness, reduces backend database load, and improves scalability.
