Exam AZ-305 topic 4 question 77 discussion

Pretty straightforward this time: A. Azure Cache for Redis - Cache the data so users can achieve them quicker B. Azure Content Delivery Network (CDN) - There isn't any issue with the networking C. Azure Data Factory - This tool is for orchestration, not for enhancing anything existing D. Azure Synapse Analytics - Also an orchestration tool with additional data warehouse capabilities, not relevant in this case

A. Azure Cache for Redis Explanation: Azure Cache for Redis provides an in-memory data store based on open-source software Redis. It can be used to cache the most frequently accessed data, thus significantly reducing latency and increasing throughput for the application data requests. By storing data that's accessed often in a cache, you can improve app performance by reducing the load on your main database and make the app more responsive even during high traffic. Azure Content Delivery Network (CDN) is more for delivering static content to users, and not designed for database queries.

A is correct

Given Answer A is correct Distributed, in-memory, scalable solution providing super-fast data access. As traffic and demands on your app increase, scale performance simply and cost-effectively. Add a quick caching layer to the application architecture to handle thousands of simultaneous users with near-instant speed—all with the benefits of a fully managed service. Features: * Superior throughput and performance to handle millions of requests per second with down to sub-millisecond latency * Fully managed service with automatic patching, updates, scaling, and provisioning so you can focus on development * RedisBloom, RediSearch, RedisJSON, and RedisTimeSeries module integration, supporting data analysis, search, and streaming * Powerful capabilities including clustering, active geo-replication, Redis on Flash, and availability of up to 99.999 percent

"Azure Cache for Redis" is the correct answer. I think the other solutions are like using a shotgun to kill flies.

A is the answer. https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-overview Azure Cache for Redis provides an in-memory data store based on the Redis software. Redis improves the performance and scalability of an application that uses backend data stores heavily. It's able to process large volumes of application requests by keeping frequently accessed data in the server memory, which can be written to and read from quickly. Redis brings a critical low-latency and high-throughput data storage solution to modern applications.

Caching: Implementing a caching mechanism, such as Redis, can help to reduce the number of requests made to the Azure SQL database. This can improve the performance of data retrieval for users.
