HPE7-J02 Exam Dumps - HPE Storage Solutions Questions and Answers

Detailed Explanation:

Rationale for Correct Answer:

HPE CloudPhysics provides comprehensive environment assessment and competitive sizing for virtualized environments (VMware, Hyper-V, etc.). The CloudPhysics collector (available as a .vhdx for Hyper-V) is deployed into the cluster to gather metrics on CPU, memory, storage IOPS/latency, and utilization trends. These analytics feed into the sizing of HPE storage solutions.

Distractors:

B: InfoSight sizing tools work with HPE systems, not competitive 3rd-party storage like Pure.

C: SAF is a manual assessment requiring email submission and is not the correct modern method for this case.

D: NinjaProtected applies to backup analysis, not production Hyper-V cluster sizing.

Key Concept: CloudPhysics.vhdx collector for Hyper-V sizing with 3rd-party infrastructure.

Detailed Explanation:

Rationale for Correct Answer:

HPE StoreOnce Dual Authorization prevents a single administrator from deleting, expiring, or modifying backup data. Instead, any destructive action requires approval from a second administrator, mitigating insider threats and accidental deletions. This is the correct feature for immutability protection in a replicated StoreOnce environment.

Distractors:

B (CHAP): Used for iSCSI authentication, not backup immutability.

C: Encryption protects data confidentiality, not accidental deletion.

D: Resource restrictions are policy-driven but don’t enforce dual control over destructive actions.

Key Concept: Dual Authorization for ransomware and insider-threat protection on StoreOnce.

Detailed Explanation:

Rationale for Correct Answer:

Option A is correct because Fibre Channel over Ethernet (FCoE) is designed for large enterprise environments that already have Fibre Channel (FC) infrastructures but want to simplify cabling and reduce hardware by converging LAN and SAN traffic over a single Ethernet fabric. FCoE retains the efficiency, low latency, and reliability of Fibre Channel while leveraging Ethernet to minimize physical infrastructure costs. This aligns with HPE’s best practices for environments using HPE Alletra 9000/Primera or HPE Nimble arrays connected to converged networks where cost reduction and high performance are equally important.

Analysis of Incorrect Options (Distractors):

B: Real-time replication across WANs requires protocols like HPE 3PAR/Alletra Remote Copy, asynchronous/synchronous replication, or HPE Peer Persistence. FCoE is not suited for high-latency WANs because it is a LAN protocol designed for short distances within a data center.

C: For inter-data center SAN unification, FCIP (Fibre Channel over IP) or iSCSI are more suitable. FCoE does not handle long-distance high-latency links effectively.

D: A startup building AI applications with cloud workloads typically benefits from object storage (HPE Scality RING, HPE GreenLake for File and Object) or direct cloud-native APIs (S3/Blob). FCoE is irrelevant in this use case since it is on-prem and infrastructure-focused.

Key Concept:

The question is testing knowledge of FCoE and its appropriate deployment scenarios — specifically, its role in consolidating storage and network traffic inside enterprise data centers while preserving Fibre Channel protocol advantages.

Detailed Explanation:

Rationale for Correct Answer:

HPE Morpheus can run as a single VM in non-critical environments, but for high availability (HA) without distributed databases, the recommendation is to deploy 3 VMs in a cluster. This ensures quorum and redundancy across application nodes, protecting against single VM failure. Distributed database mode requires more VMs, but is not needed in this scenario.

Distractors:

A: 4 VMs are required only if distributed DB is enabled (PostgreSQL cluster), not here.

B/D: A single VM (with or without VMware HA) doesn’t provide native Morpheus HA resilience.

Key Concept: Morpheus HA = 3-node cluster minimum without distributed DB.

Detailed Explanation:

Rationale for Correct Answer:

For competitive or 3rd-party (non-HPE) environments like Dell + VMware, HPE CloudPhysics is the correct tool. The Observer VM is deployed into vCenter to gather real-world workload metrics (CPU, memory, storage I/O). These analytics can then be used for SimpliVity HCI sizing.

Distractors:

A: NinjaOnline SimpliVity Sizer requires input metrics, but it cannot directly collect from 3rd-party environments.

B: InfoSight sizing applies to HPE arrays, not competitive storage.

D: InfoSight for SimpliVity only monitors existing HPE SimpliVity clusters.

Key Concept: CloudPhysics Observer → gathers competitive workload metrics → feeds into SimpliVity sizing.

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.

Detailed Explanation:

Rationale for Correct Answer:

From the exhibit, the system shows maximum estimated IOPS performance (over 250K IOPS read, 115K IOPS mixed, 62K write). These values align with HPE’s published performance specifications for this model with full cores enabled. The network interface count and disk count are balanced relative to controller capability. Therefore, no further upgrades are required to achieve maximum performance.

Distractors:

A: Adding NICs/HBAs may improve throughput but will not exceed controller-bound IOPS.

B: Adding disks increases capacity, not peak IOPS, as performance is primarily controller-driven.

D: The system already matches controller capability; upgrading cores is not an option in Alletra MP B10000 mid-range systems.

Key Concept: Understanding performance sizing based on controller and architecture limits, not just capacity or NICs.

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.

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.
