In a FlexCache relationship, what is a key role of the origin volume besides hosting data blocks?

• A. To track cache relationships and coherency information for FlexCache volumes
• B. To store backups of the origin data
• C. To distribute reads to clients directly
• D. To manage replication across clusters

Answer: (A)

In FlexCache, the origin volume does more than just store data blocks; it is the authoritative source for the metadata that coordinates caching across all cache volumes. It tracks the relationships between the origin and the caches and maintains coherency information, so caches know which blocks are valid, where they came from, and when to invalidate or refresh them as data changes on the origin. This ensures consistent, up-to-date reads across the distributed cache setup. Backup storage, distributing reads directly to clients, or managing replication across clusters are separate concerns and not the primary role of the origin in a FlexCache relationship.
