ALocMemCache, because it is fast and stores data in local memory.
BFileBasedCache, because it stores cache in files accessible by all servers.
CDatabase cache, because it is the fastest for distributed caching.
DRedis or Memcached, because they support shared cache across multiple servers.
Step-by-Step Solution
Solution:

  1. Step 1: Understand caching needs for distributed apps

    Distributed apps require a cache backend that can share data across multiple servers.

  2. Step 2: Evaluate cache backends for multi-server support

    LocMemCache stores data only in local memory, FileBasedCache is slow and not ideal for concurrency, Database cache is slower. Redis and Memcached are designed for shared caching across servers.

  3. Final Answer:

    Redis or Memcached, because they support shared cache across multiple servers. -> Option D

  4. Quick Check:

    Distributed cache needs shared backend = Redis/Memcached [OK]
Quick Trick: Use Redis or Memcached for multi-server shared caching [OK]
