Free and Premium HP HPE7-J02 Dumps Questions Answers

Detailed Explanation:

Rationale for Correct Answer:

HPE CloudPhysics provides comprehensive environment assessment and competitive sizing for virtualized environments (VMware, Hyper-V, etc.). The CloudPhysics collector (available as a .vhdx for Hyper-V) is deployed into the cluster to gather metrics on CPU, memory, storage IOPS/latency, and utilization trends. These analytics feed into the sizing of HPE storage solutions.

Distractors:

B: InfoSight sizing tools work with HPE systems, not competitive 3rd-party storage like Pure.

C: SAF is a manual assessment requiring email submission and is not the correct modern method for this case.

D: NinjaProtected applies to backup analysis, not production Hyper-V cluster sizing.

Key Concept: CloudPhysics.vhdx collector for Hyper-V sizing with 3rd-party infrastructure.

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 Alletra 5000/6000 sizing, the Failure Domain Reserve (FDR) is used to account for rebuild overhead in case of drive failure. HPE best practices define that, unless otherwise directed by the sizing tool or customer requirements, the minimum FDR value should be set to 23% of the largest drive size. This ensures enough reserve capacity for fault tolerance and sustained performance during rebuilds.

Distractors:

B/C: Low-read latency is influenced by cache and workload profile, not by arbitrary FDR percentages.

D: Using the smallest drive is incorrect — rebuild impact must be sized against the largest drive.

Key Concept: FDR sizing based on 23% of largest drive = HPE best practice.

Detailed Explanation:

Rationale for Correct Answer:

HPE GreenLake for Containers delivers an enterprise-grade Kubernetes platform, leveraging open-source Kubernetes but with simplified lifecycle management, monitoring, and integration with HPE infrastructure. It provides full support for containerized workloads, whether cloud-native or modernized traditional applications.

Distractors:

A: Incorrect — not about legacy virtualization.

B: Incorrect — microservices are supported; orchestration is Kubernetes-native.

D: Incorrect — it supports both cloud-native and modernized workloads.

Key Concept: GreenLake for Containers = Kubernetes with simplified enterprise management.

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:

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:

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:

For competitive or 3rd-party (non-HPE) environments like Dell + VMware, HPE CloudPhysics is the correct tool. The Observer VM is deployed into vCenter to gather real-world workload metrics (CPU, memory, storage I/O). These analytics can then be used for SimpliVity HCI sizing.

Distractors:

A: NinjaOnline SimpliVity Sizer requires input metrics, but it cannot directly collect from 3rd-party environments.

B: InfoSight sizing applies to HPE arrays, not competitive storage.

D: InfoSight for SimpliVity only monitors existing HPE SimpliVity clusters.

Key Concept: CloudPhysics Observer → gathers competitive workload metrics → feeds into SimpliVity sizing.

Detailed Explanation:

Rationale for Correct Answer:

Changing HA from Drive Level to Enclosure Level means the system must reserve additional capacity to tolerate the loss of an entire disk enclosure. This decreases usable capacity, as more parity/spare space is required. Performance remains similar, but capacity overhead increases.

Distractors:

A: Multiple enclosures exist in the config; option is valid.

B: Switched vs direct-connect is unrelated to HA settings.

C: Performance estimates are not directly reduced by HA level change; capacity is.

Key Concept: Enclosure HA = more reserve overhead → less usable capacity.

Detailed Explanation:

Rationale for Correct Answer:

In Brocade (HPE B-Series) SAN switches, FCIP trunking allows multiple IP circuits to be aggregated. This increases bandwidth and provides resiliency (if one link fails, traffic continues over remaining paths). It is the correct statement regarding HPE’s FCIP feature set.

Distractors:

B: High availability still requires redundant fabrics; FCIP trunking alone doesn’t replace fabric design best practices.

C: FCIP can run over shared IP WANs; no need for dedicated links.

D: Encryption adds overhead; performance impact exists (although minimal with hardware offload).

Key Concept: FCIP trunking = bandwidth + availability for multisite SAN.

Detailed Explanation:

Rationale for Correct Answer:

HPE SimpliVity RapidDR simplifies and automates DR failover processes, but execution requires an authorized operator to trigger a pre-configured recovery plan. This balances automation with compliance and security requirements (important for healthcare). It does not guarantee zero RTO, but it does minimize RTO through automation.

Distractors:

A: RTO of 0 is not possible; RapidDR reduces but does not eliminate recovery time.

B: Domain admin credentials for re-IP are not required; automation handles reconfiguration.

C: Auto-commit/rollback require administrator validation; no “silent” automation is allowed for compliance.

Key Concept: RapidDR = automation of failover/failback but requires authorized trigger.

Detailed Explanation:

Rationale for Correct Answer:

From the exhibit, the system shows maximum estimated IOPS performance (over 250K IOPS read, 115K IOPS mixed, 62K write). These values align with HPE’s published performance specifications for this model with full cores enabled. The network interface count and disk count are balanced relative to controller capability. Therefore, no further upgrades are required to achieve maximum performance.

Distractors:

A: Adding NICs/HBAs may improve throughput but will not exceed controller-bound IOPS.

B: Adding disks increases capacity, not peak IOPS, as performance is primarily controller-driven.

D: The system already matches controller capability; upgrading cores is not an option in Alletra MP B10000 mid-range systems.

Key Concept: Understanding performance sizing based on controller and architecture limits, not just capacity or NICs.
