HP Advanced HPE Storage Integrator Solutions Written HPE7-J02 Exam Questions

Answer : A

Detailed Explanatio n:

Rationale for Correct Answe r:

The exhibit shows the use of 32Gb FC HBAs and 100GbE switches (Aruba 100G). However, the customer specifically requires 25GbE top-of-rack switches. Therefore, the configuration needs to be corrected to 25GbE networking. The HPE Alletra MP B10000 guarantees 100% data availability SLA, so the primary correction is networking alignment, not drives or financial model.

Distractors:

B: Reducing drives reduces raw capacity below 80TB requirement.

C: GreenLake is a consumption model but not the technical correction required.

D: Aruba 8325 is a core switch option; customer only asked for ToR 25GbE.

Key Concept: Networking alignment with requirements.

Answer : B

Rationale for Correct Answe r:

With Alletra and Primera Peer Persistence, the Quorum Witness is no longer a self-hosted VM. It is delivered as a cloud-based SaaS service managed by HPE. This eliminates customer responsibility for patching and ensures HPE automatically applies updates and security fixes. This resolves the audit concern.

Distractors:

A: Applies to older 3PAR environments, not Alletra/Primera.

C/D: Quorum Witness is no longer an appliance --- it is SaaS managed, so these don't apply.

Key Concept: Alletra Quorum Witness is SaaS-managed, removing patching responsibility.

Answer : A

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.

Answer : B

HPE NinjaSTARS (Storage Assessment and Right Sizing) is the dedicated HPE tool for sizing and configuring StoreOnce backup appliances. It evaluates backup datasets, retention policies, deduplication ratios, and replication to recommend the right StoreOnce model and configuration.

Distractors:

A (CloudPhysics): Used for virtual infrastructure and block storage assessments, not backup target sizing.

C (Ninja Online): General sizing tool, not specific for StoreOnce.

D (OCA): Used for quoting/configuration, but sizing requires NinjaSTARS first.

Key Concept: HPE NinjaSTARS is the StoreOnce sizing tool.

Answer : A

Detailed Explanatio n:

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.

Answer : B

Detailed Explanatio n:

Rationale for Correct Answe r:

The exhibit shows a system delivering ~2.3 GB/s sequential read. For large-block sequential workloads, aggregate host link bandwidth (number speed of front-end ports) is the primary limiter. Increasing the count of 10/25 Gb iSCSI NICs adds parallel lanes, raising sustained read GB/s to the hosts. This is a recommended first step in HPE sizing before changing protocols.

Analysis of Incorrect Options (Distractors):

A: Adding an expansion shelf increases capacity, not front-end bandwidth.

C: Moving to 32 Gb FC can help, but simply adding more existing 10/25 Gb ports achieves the same goal without a protocol/adapter change and is the straightforward, supported scale-out path.

D: SCM (Storage Class Memory) targets latency/IOPS; it doesn't materially lift sequential GB/s if the link budget is the bottleneck.

Key Concept: Scale front-end connectivity to increase sequential throughput; capacity or media class changes won't fix a link-limited system.

Answer : D
