HPE7-J02 Exam - Topic 7 Question 6 Discussion

Detailed Explanatio n:

Rationale for Correct Answe r:

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.
