FlexCache caching focuses on which type of data to improve performance?

• A. Inactive data
• B. Only metadata
• C. All data on demand
• D. Active, frequently read data

Answer: (D)

FlexCache caching targets data that clients are actively reading, keeping the hot, frequently accessed blocks in the local cache. By storing this active data close to the users, subsequent reads are served quickly from the cache rather than across the network to the origin, delivering lower latency and reduced WAN traffic. Inactive data isn’t prioritized for caching because it wouldn’t yield noticeable performance benefits, and caching only metadata wouldn’t provide the actual data the clients need. Data is brought into the cache on demand as it’s accessed, but the decision to retain items in cache focuses on how often and how recently they’re read.
