   How does asynchronous replication affect durability compared to synchronous replication?

   • AAsynchronous replication provides better durability because it uses compression.
   • BAsynchronous replication is only used for backup, not for durability.
   • CAsynchronous replication can lose data that was written after the last replication cycle.
   • DAsynchronous replication provides the same durability as synchronous replication.

   A cloud storage provider is designing a new storage tier for archival data. They need to achieve 11 nines of durability while minimizing storage cost. The data is written once and rarely read. They are considering erasure coding with a 6+3 scheme versus triple replication. Which factor is most important in their decision?

   • ATriple replication is more durable than erasure coding.
   • BErasure coding uses less storage overhead than replication, reducing cost.
   • CTriple replication provides faster read performance than erasure coding.
   • DErasure coding is simpler to implement than replication.

   A research institute stores large genomic datasets on ONTAP. The data is written once and rarely modified, but it must be protected against disk failures and accidental deletion. The institute wants to keep multiple point-in-time copies for 7 years. Which combination of NetApp features best meets these requirements?

   • ARAID-DP and SnapMirror
   • BRAID-DP and SnapVault
   • CSynchronous SnapMirror and RAID-TEC
   • DAsynchronous SnapMirror and SnapVault

   A hospital's electronic health record (EHR) system stores patient data on ONTAP. The system must be available 24/7, and the hospital can tolerate up to 15 minutes of downtime but no data loss. The storage team is evaluating a design that uses synchronous SnapMirror to a secondary site. Which additional consideration is most critical to meet the RTO of 15 minutes?

   • AUsing asynchronous replication to reduce network latency
   • BPlacing the secondary site in the same data center
   • CConfiguring automatic failover and testing the failover procedure regularly
   • DEnsuring the secondary site has enough capacity to hold a full copy of the data

   What is a key characteristic of synchronous replication?

   • AData is replicated to a single replica to reduce network bandwidth usage.
   • BData is replicated periodically, which can result in some data loss if the primary fails.
   • CData is written to the primary and replica simultaneously, ensuring zero data loss.
   • DData is replicated only when the primary site is under heavy load.
