What is the primary purpose of FlexCache in a distributed team scenario?

• A. It duplicates origin data locally for faster reads.
• B. It serves frequently accessed read data from the nearest cache site.
• C. It relies on the origin for all reads.
• D. It caches only write data for later synchronization.

Answer: (B)

The key idea is to place a fast read cache close to users so common reads come from a nearby cache rather than the distant origin. In a distributed team, people at different sites often request the same data. FlexCache keeps frequently accessed data at the edge cache sites, so those reads are served quickly from the local cache, reducing latency and WAN traffic. If a requested item isn’t in the local cache yet, it is fetched from the origin and stored there for future requests, so subsequent reads are faster. It speeds up reads without duplicating all origin data locally, and it doesn’t depend on the origin for every read or focus solely on caching writes.
