HPE7-J02 Advanced HPE Storage Integrator Solutions Written Exam Questions and Answers

Detailed Explanation:

Rationale for Correct Answer:

The choice of assessment tool (e.g., HPE CloudPhysics for VMware vs. CloudPhysics.vhdx collector for Hyper-V) depends primarily on the virtualization platform in use. VMware and Hyper-V require different collectors, and this is the deciding factor for tool selection.

Distractors:

A: Public cloud use matters for hybrid sizing but not for tool selection.

C: Expired contracts are unrelated to tool choice.

D: Procurement model (CapEx vs. GreenLake) is separate from sizing assessment.

Key Concept: Assessment tool choice = based on hypervisor platform (VMware vs Hyper-V).

Detailed Explanation:

Rationale for Correct Answer:

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.

Detailed Explanation:

Rationale for Correct Answer:

HPE GreenLake for File Storage, powered by VAST Data software, natively supports cross-protocol access (NFS, SMB, and S3) to the same dataset. This means a file written via NFS can be accessed via SMB or S3 without replication. For cross-protocol access, both protocols must be enabled at the share/bucket level. This is a core differentiator of HPE’s GreenLake for File Storage solution.

Distractors:

A: Wrong, because GreenLake for File Storage already has native multi-protocol support — no need for 3rd party SDS.

C: Incorrect, as replication between separate shares is not required; it is a native capability.

D: Misleading — IP pools are used for load balancing and client connectivity, but not required to enable cross-protocol access.

Key Concept: Multi-protocol access in HPE GreenLake for File Storage (NFS/SMB/S3).

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:

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.

Detailed Explanation:

Rationale for Correct Answer:

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.

Detailed Explanation:

Rationale for Correct Answer:

When using Zerto Move, unlike a typical disaster recovery failover, the migration process allows the source VMs to be retained after cutover. This is useful when testing or validating the migration. In contrast, failover scenarios typically assume the source environment has failed or is decommissioned. Therefore, keeping source VMs is a differentiator for Move.

Distractors:

A: Checkpoints and RPO are controlled by Zerto replication but are not selectable per migration cutover in this way.

B: Source VMs are not deleted automatically; this is intentionally avoided to allow rollback.

D: While Zerto does provide low RPO/RTO (seconds to minutes), this applies mainly to DR failover, not migration cutovers.

Key Concept: Zerto Move vs Zerto Failover semantics.

Detailed Explanation:

Rationale for Correct Answer:

FC-FC routing (also known as Fibre Channel Routing / LSANs on B-Series switches) allows replication between separate SAN fabrics without merging them. This supports disaster recovery scenarios while preserving fabric isolation, exactly matching the bank’s requirement.

Distractors:

A: FCIP tunnels extend Fibre Channel over IP networks, but this typically merges SAN domains.

C: NPIV (N_Port ID Virtualization) allows multiple virtual WWNs per port, not cross-fabric replication.

D: Fabric partitioning is zoning and segmentation within a single fabric, not between independent fabrics.

Key Concept: FC-FC routing on Brocade (B-Series) for SAN isolation with replication.

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 CloudPhysics begins collecting performance and capacity data immediately after deployment of the Observer VM/collector. Some initial assessment results (e.g., environment inventory, early utilization stats) can be visible within 2 hours, while deeper trending insights require longer data collection (days/weeks).

Distractors:

B: Tokens are not required for customers to view results; reports are available via the portal.

C: Customers get a full dashboard view of results, not partial.

D: Assessments can run for longer periods (days–weeks), not fixed at 5 days.

Key Concept: CloudPhysics delivers initial insights within hours.

Detailed Explanation:

Rationale for Correct Answer:

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.

Detailed Explanation:

Rationale for Correct Answer:

HPE Alletra 6000 is a scale-out architecture array. Adding more arrays to a single scale-out group increases both performance (IOPS, throughput) and capacity, while maintaining single-pane management via HPE Data Services Cloud Console. This is the most efficient way to address both capacity growth and latency reduction for SQL workloads.

Distractors:

B: Adding NICs may help with throughput but not backend latency or capacity scaling.

C: Flash-to-cache ratios can optimize read caching but don’t fundamentally increase system-wide performance.

D: Timeless storage is a procurement/licensing option, not a performance/capacity scaling method.

Key Concept: Alletra 6000 scale-out clustering for balanced growth of capacity and performance.
