Which cache type is associated with the acronym replicate-via-invalidation?

• A. Local Cache
• B. Distributed Cache
• C. Hybrid Cache
• D. None of the Above

Answer: (C)

Cache coherence across nodes and how updates propagate is what this item tests. Replicate-via-invalidation describes keeping multiple caches in sync by invalidating other copies when a write occurs, rather than pushing every update to all replicas. This approach blends replication with invalidation to strike a balance between fast read access and lower update traffic. That blend is characteristic of a Hybrid Cache, which uses multiple strategies to maintain coherence. A Local Cache lives on a single node, so cross-node invalidation isn’t part of its behavior, and a purely Distributed Cache often emphasizes one primary mechanism (such as full replication or a partitioned approach) rather than this mixed pattern. Thus, the term aligns with Hybrid Cache.
