What are the key considerations for volume replication in PowerFlex? (Choose two)

Question

Options

• ASufficient network bandwidth between clusters
• BPredefined snapshot retention policies
• CIdentical storage pool configurations
• DCompatible replication protocols

• A
  76% (37)
• B
  16% (8)
• C
  8% (4)

Explanation

Volume replication in PowerFlex requires data to physically travel across a network to a target cluster, making sufficient network bandwidth (A) critical - inadequate bandwidth causes replication lag, missed RPO targets, and potential data loss. Compatible replication protocols (D) are equally essential because source and target systems must speak the same replication "language" to establish and maintain a valid replication session; mismatched protocols simply prevent replication from functioning.

Option B (snapshot retention policies) is a distractor because snapshot schedules are a separate data protection concern - they govern local recovery points, not the replication mechanism itself. Option C (identical storage pool configurations) is incorrect because PowerFlex replication does not mandate matching pool configurations between source and target; the target pool just needs adequate capacity and compatible tier settings, not a mirror-image layout.

Memory tip: Think of replication like a phone call - you need a strong enough signal (bandwidth) and both phones must support the same network standard (compatible protocols). Snapshots and pool layouts are internal housekeeping that don't affect whether the call connects.
