OceanStor Dorado HyperReplication for NAS only supports async replication, for sync replication, which feature should be used? (Single-choice)

Explanation

HyperMetro (C) provides synchronous active-active replication for NAS, delivering zero RPO by writing data to both sites simultaneously before acknowledging the write - exactly what's needed when async HyperReplication falls short for NAS workloads.

Why the distractors are wrong:

• A. HyperClone - a local cloning/snapshot feature used to create instant copies of data within the same system, not a cross-site replication solution.
• B. HyperLock - a WORM (Write Once, Read Many) compliance feature that prevents data from being modified or deleted; it's about data immutability, not replication.
• D. HyperCDP - Continuous Data Protection that captures every write as a recovery point for granular point-in-time recovery; it's a local data protection feature, not synchronous remote replication.

Memory tip: Think of "Metro" as in a metropolitan area - HyperMetro links two sites like two stations on the same metro line, keeping them in perfect sync at all times. When you need sync, think Metro.
