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

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.

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.

Rationale for Correct Answer:

In Alletra 6000 Peer Persistence environments, operations like resizing Peer Persistence volumes must be performed via the HPE Data Services Cloud Console (DSCC), which manages volume collections and replication consistency groups. Attempting to grow the upstream volume locally will fail because the changes need to propagate across both sites consistently.

Distractors:

A/B: Removing upstream or downstream volumes would break replication and is not required.

D: Expanding in VMware only extends the VMFS datastore, not the underlying replicated volume.

Key Concept: Peer Persistence volume resizing is done in DSCC, not local web GUI.

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).
