HPE7-J02 Questions and Answers

Detailed Explanation:

Rationale for Correct Answer:

The requirements align with a Capital Purchase — outright ownership with a one-time CapEx expense. This provides complete lifecycle control and no ongoing payments, fitting the financial services company’s budgeting and governance model.

Distractors:

A: Operating lease is OpEx, variable payments, and no ownership.

B: Capital lease provides eventual ownership but still requires periodic lease payments.

C: Consumption model (e.g., GreenLake) uses variable OpEx, opposite of the customer’s request.

Key Concept: CapEx model = one-time purchase, ownership, full control.

Rationale for Correct Answer:

In the Zerto Vault architecture, production workloads replicate continuously to a Replication Target (secondary site). From there, data is further replicated periodically and encrypted into the Vault (air-gapped, isolated site). This two-step process ensures ransomware resilience and immutability, as the Vault acts as a hardened third copy.

Distractors:

A: Production-to-replication target traffic is continuous synchronous/asynchronous replication, not periodic. Periodic replication applies to Replication Target → Vault.

C: The Resilience Automation Server (RAS) is responsible for orchestrating failover and immutability enforcement, but it does not control port access between production and replication target.

D: Snapshots of Zerto components are not what is replicated — it’s application data VMs/volumes. The Vault ensures immutability of replicated data, not ZVM components.

Key Concept: Zerto Vault = encrypted, periodic replication from replication target to immutable vault.

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:

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:

A Capital Lease (also known as a finance lease) spreads costs over time like OpEx, while giving the customer the ability to own the equipment at the end of the lease term. This matches the desire for predictable payments, eventual ownership, and full control.

Distractors:

A (Consumption model): GreenLake provides OpEx flexibility but does not lead to ownership.

B (Operating lease): Pure rental; equipment must be returned, no ownership.

C (Capital purchase): Requires large upfront payment, which the customer wants to avoid.

Key Concept: Capital Lease = predictable payments + ownership path.

Detailed Explanation:

Rationale for Correct Answer:

Frequent cache misses occur when the working dataset does not fit effectively in cache. Increasing the flash-to-disk ratio ensures a higher portion of hot data is served from flash media rather than backend disk, reducing cache miss penalties. This is the standard HPE recommendation for read-intensive workloads where cache is insufficient.

Distractors:

A: Adding shelves adds capacity, not cache-to-data efficiency.

B: Upgrading controllers increases CPU, but not necessarily cache efficiency.

C: Pinned cache is intended for metadata or specific workloads, not large-scale read caching.

Key Concept: Flash-to-disk ratio optimization reduces cache misses.

Detailed Explanation:

Rationale for Correct Answer:

After installing the HPE CSI driver and creating backend secrets, the next critical step is to define a StorageClass that references the backend driver and parameters. Without the StorageClass, Kubernetes cannot dynamically provision PersistentVolumes (PVs). Once the StorageClass is created, workloads can request storage using PersistentVolumeClaims (PVCs).

Distractors:

A: Helm repo update only refreshes Helm charts; it does not enable CSI provisioning.

B: A PVC requires a StorageClass to bind dynamically — it cannot be created successfully beforehand.

C: Manually creating PVs is possible, but not the HPE best practice with CSI, which relies on StorageClass for dynamic provisioning.

Key Concept: Kubernetes CSI workflow: Secret → StorageClass → PVC → Pod.

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.
