Two HPE Alletra 6000 arrays are configured for peer persistence between datacenters A and B,...

Detailed Explanation:

Rationale for Correct Answer:

HPE Peer Persistence is supported over distances of up to 150–200 km, as long as the round-trip latency is ≤10ms. Therefore, even after relocation to 150km, Peer Persistence remains supported provided latency requirements are met.

Distractors:

B: RC (Remote Copy) transport is already the underlying technology, but no change is required.

C: Peer Persistence is already an active-active design; no change to “active” mode is needed.

D: Distance does not exceed the supported range; only latency matters.

Key Concept: Latency <10ms is the critical requirement for Peer Persistence.
