Rationale for Correct Answe r:

The exhibit shows an Alletra MP configuration delivering ~4.6 GB/s (256 KB sequential read) with four 10 Gb host ports. That throughput is close to the aggregate front-end bandwidth ceiling of 410 GbE (5 GB/s raw, less with protocol overhead). For large-block sequential workloads, the front-end link budget is often the bottleneck; adding additional 10 GbE ports (or moving to higher-speed links) increases available host bandwidth and raises sustained sequential read throughput. This aligns with HPE sizing guidance: scale host connectivity to meet sequential throughput targets before adding media.

Analysis of Incorrect Options (Distractors):

B: Adding a third node isn't applicable to a 2-node HA block pair and would not address a front-end bandwidth limit.

C: More controller cores don't raise link-level throughput if host I/O is already constrained by port bandwidth.

D: Adding NVMe media primarily boosts IOPS/parallelism; sequential read is bounded here by front-end ports.

Key Concept: Sequential throughput is front-end bandwidth bound; scale host ports to increase GB/s.

Rationale for Correct Answe r:

In the exhibit, several paths show ''Standby'' and some appear ''Dead'', while only a subset is Active (0). This typically indicates that one storage controller may be missing or offline, which reduces redundancy and can cause performance degradation. In a healthy Peer Persistence environment, both controllers should present active and non-optimized paths.

Distractors:

A & B: Having multiple active paths does not inherently reduce performance; in fact, MPIO load balances traffic. The issue here is path failures, not excessive active paths.

Key Concept: MPIO pathing in HPE Peer Persistence and controller health.

Rationale for Correct Answe r:

In Alletra 6000 Peer Persistence environments, operations like resizing Peer Persistence volumes must be performed via the HPE Data Services Cloud Console (DSCC), which manages volume collections and replication consistency groups. Attempting to grow the upstream volume locally will fail because the changes need to propagate across both sites consistently.

Distractors:

A/B: Removing upstream or downstream volumes would break replication and is not required.

D: Expanding in VMware only extends the VMFS datastore, not the underlying replicated volume.

Key Concept: Peer Persistence volume resizing is done in DSCC, not local web GUI.

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.

Rationale for Correct Answe r:

A Capital Lease (also known as a finance lease) spreads costs over time like OpEx, while giving the customer the ability to own the equipment at the end of the lease term. This matches the desire for predictable payments, eventual ownership, and full control.

Distractors:

A (Consumption model): GreenLake provides OpEx flexibility but does not lead to ownership.

B (Operating lease): Pure rental; equipment must be returned, no ownership.

C (Capital purchase): Requires large upfront payment, which the customer wants to avoid.

Key Concept: Capital Lease = predictable payments + ownership path.
