Question

You are using Memorystore for Redis to cache frequently accessed data and improve your application's performance. Recently, your application is experiencing sudden spikes in latency when interacting with the Memorystore for Redis instance. Upon checking the logs, you discover a high number of "evicted keys" messages. You want to reduce the occurrences of latency spikes and their impact on the application. What should you do?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Scale the Memorystore instance to a larger memory size. Memorystore provides managed in-memory Redis/Memcached caching to reduce latency and offload databases. This option decouples the components so they scale independently and absorb load spikes.
