AZ-204 Certification Practice Question #196

Question

You have a Standard tier instance of Azure Cache for Redis named redis1 configured with the default settings.

You need to configure a Maxmemory policy to increase the amount of cache available for read operations.

How should you configure the Maxmemory policy?

Accepted Answer

`maxmemory-reserved` reserves memory for internal Redis operations (replication, failover). By decreasing this reserved amount, more memory becomes available for storing cached data, which directly increases the amount of cache available for read operations. Option B does the opposite. Option C (noeviction) would prevent writing new data when full. Option D (volatile-lru) is already the default on Standard tier and does not increase total available memory — it only changes eviction behavior. The MS Learn docs and 13 community votes confirm A.
