Which NetApp features are used for disaster recovery replication?

• A. SAML authentication
• B. Data deduplication and compression
• C. Volume replication only
• D. SnapMirror and SnapVault

Answer: (D)

Disaster recovery replication in NetApp is driven by SnapMirror and SnapVault. SnapMirror creates a live replica of your data volumes at a secondary site, enabling quick failover and maintaining near real-time continuity of services. SnapVault complements this by providing backups of those snapshots on a separate system or storage, supporting long-term retention and point-in-time recovery. The other options don’t address replication: SAML authentication handles access control, not data replication; data deduplication and compression improve storage efficiency but don’t provide DR replication; and saying “volume replication only” is incomplete without specifying NetApp’s dedicated replication and backup mechanisms. Together, SnapMirror and SnapVault cover both replication for disaster recovery and backup for restore flexibility.
