Authentic HP Certification Exam HPE7-J02 Questions Answers

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.

Detailed Explanation:

Rationale for Correct Answer:

The choice of assessment tool (e.g., HPE CloudPhysics for VMware vs. CloudPhysics.vhdx collector for Hyper-V) depends primarily on the virtualization platform in use. VMware and Hyper-V require different collectors, and this is the deciding factor for tool selection.

Distractors:

A: Public cloud use matters for hybrid sizing but not for tool selection.

C: Expired contracts are unrelated to tool choice.

D: Procurement model (CapEx vs. GreenLake) is separate from sizing assessment.

Key Concept: Assessment tool choice = based on hypervisor platform (VMware vs Hyper-V).

Detailed Explanation:

Rationale for Correct Answer:

Option B (All) is correct because in an Active Peer Persistence deployment where both arrays and hosts are in close proximity (metro or campus cluster scenario), the hosts should be configured with Host Proximity = All. This ensures that the host (ESX31) can access both arrays symmetrically and concurrently, enabling active-active paths. This is essential to deliver seamless failover and load balancing across the arrays in an HPE Alletra MP Peer Persistence environment.

Analysis of Incorrect Options (Distractors):

A (Secondary): This is used for hosts located closer to the secondary array, to bias access toward it in asymmetric deployments. Not applicable here since the hosts are near both arrays.

C (Exclusive): This option assigns the host to a single array exclusively, preventing dual-active access. This would defeat the purpose of symmetric Peer Persistence.

D (Primary): Similar to Secondary, this biases access to only the primary array, which is not correct when arrays and hosts are in the same site for active-active.

Key Concept:

This question focuses on Host Proximity parameters in HPE Peer Persistence.

Primary/Secondary = asymmetric designs (hosts closer to one array).

All = symmetric design (hosts equidistant to both arrays, enabling active-active).

Exclusive = restricts access to one array only.
