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

Detailed Explanation:

Rationale for Correct Answer:

For HPC and AI/ML workloads, NFS over RDMA (Remote Direct Memory Access) provides significantly lower latency and reduced CPU overhead compared to standard NFS over TCP. This allows direct memory-to-memory data transfers between storage and compute nodes, bypassing the kernel network stack. In VAST Data (underpinning GreenLake for File Storage), NFS over RDMA is explicitly supported to accelerate shared dataset access in HPC and AI environments.

Distractors:

A: Standard NFS introduces more latency due to kernel TCP/IP stack overhead.

C: RoCE (RDMA over Converged Ethernet) is a transport layer technology — useful, but the protocol chosen for the file system must be NFS over RDMA, not just RoCE.

D: iSER (iSCSI Extensions for RDMA) enhances iSCSI block storage, not NFS file workloads.

Key Concept: NFS over RDMA for HPC/AI shared datasets.

Detailed Explanation:

Rationale for Correct Answer:

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.

Detailed Explanation:

Rationale for Correct Answer:

HPE PCBE provides full-stack intelligence across compute, storage, and virtualization layers. It integrates with Kubernetes distributions like Tanzu and Canonical, giving visibility and lifecycle automation across the entire stack. This helps Dev/Ops teams simplify operations, capacity planning, and performance optimization in hybrid environments.

Distractors:

B: Multi-tenant VASA applies more to VMware vVols in multi-tenant setups.

C: No platform offers “infinite scale at no cost” — this is misleading.

D: Container-level protection is delivered through HPE CSI with data protection solutions, not unique to PCBE.

Key Concept: HPE PCBE delivers unified lifecycle management with full-stack intelligence.

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 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 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.

Detailed Explanation:

Rationale for Correct Answer:

Alletra 6000 expansion shelves connect via 24G SAS back-end connectivity. The BOM must include the required SAS cables to properly attach the shelf. If only the shelf is listed, it’s incomplete — SAS connectivity accessories must be added.

Distractors:

B: The supported max capacity is higher than 138TB + 46TB, so it won’t exceed limits.

C: Expansion shelves don’t use OCP adapters; they rely on SAS backend ports.

D: QSFP+ DACs are used for front-end networking (iSCSI/FC), not SAS shelf expansion.

Key Concept: Alletra 6000 expansions require 24G SAS cables included in the BOM.

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:

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.
