Pass the HP HPE Storage Solutions HPE7-J02 Questions and answers with CertsForce

Detailed Explanation:

Rationale for Correct Answer:

In Brocade (HPE B-Series) SAN switches, FCIP trunking allows multiple IP circuits to be aggregated. This increases bandwidth and provides resiliency (if one link fails, traffic continues over remaining paths). It is the correct statement regarding HPE’s FCIP feature set.

Distractors:

B: High availability still requires redundant fabrics; FCIP trunking alone doesn’t replace fabric design best practices.

C: FCIP can run over shared IP WANs; no need for dedicated links.

D: Encryption adds overhead; performance impact exists (although minimal with hardware offload).

Key Concept: FCIP trunking = bandwidth + availability for multisite SAN.

Rationale for Correct Answer:

The Simulator for VM Rightsizing Card Deck in HPE CloudPhysics evaluates actual VM utilization against provisioned resources. It identifies under- and overprovisioned VMs, providing insights into reclaimable resources and accurate sizing recommendations. This directly helps plan server and storage upgrades.

Distractors:

A: Storage Space Management focuses on datastore usage trends, not provisioning mismatches.

B: Reclaimable VMware vDisk Space identifies unused storage, not CPU/RAM sizing.

D: Infrastructure Planning helps plan new builds but doesn’t directly analyze current over/under provisioning.

Key Concept: VM Rightsizing = CloudPhysics tool for over/under provisioning analysis.

Detailed Explanation:

Rationale for Correct Answer:

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 4×10 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 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.
