Detailed Explanation:

Rationale for Correct Answer:

Zerto, now part of HPE, provides continuous data protection (CDP) with near-zero RPOs and very low RTOs. It supports VMware workloads, as well as hybrid cloud deployments with AWS and Azure. Zerto is specifically designed for disaster recovery orchestration, enabling automated failover, failback, and application-consistent protection across sites and cloud environments.

Distractors:

B (CommVault): Primarily a backup/recovery and data management platform — RPOs are not near-zero.

C (Cohesity): Strong in backup, secondary storage, and ransomware recovery, but not near-zero RPO DR orchestration.

D (SimpliVity): Hyperconverged infrastructure with built-in backup, but not optimized for large-scale multi-cloud DR.

Key Concept: Continuous Data Protection (Zerto) for hybrid/multi-cloud disaster recovery.

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.
