Storage Replica is used to

• A. Replicate volumes between servers or clusters
• B. Provide data deduplication
• C. Enable storage virtualization
• D. Allow live migration of virtual machines

Answer: (A)

Storage Replica is about keeping copies of data in sync across different servers or clusters, so you can recover quickly if a primary site fails. It works at the block level to replicate volumes to a partner location, and you can choose synchronous replication for near-zero data loss within a local/metro distance or asynchronous replication for longer distances where latency exists. This capability enables a disaster-recovery scenario where the secondary site can take over with up-to-date data. Dedicating, deduplication, or virtualization features don’t provide that cross-site replication. Data deduplication reduces the amount of storage used but doesn’t automatically mirror data to another server. Storage virtualization abstracts multiple storage devices into a single pool, not replicate the contents to a separate site. Live migration of virtual machines moves running VMs between hosts, which is a different capability from keeping identical volume copies on separate servers.
