At ValidExamDumps, we consistently monitor updates to the HPE7-J02 exam questions by HP. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the HP Advanced HPE Storage Integrator Solutions Written Exam exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by HP in their HPE7-J02 exam. These outdated questions lead to customers failing their HP Advanced HPE Storage Integrator Solutions Written Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the HPE7-J02 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Which statement is correct when enabling port trunking (FC ISL / Ethernet link aggregation)?
Detailed Explanatio n:
Rationale for Correct Answe r:
In B-Series (Brocade) SAN switches, trunking requires that all ports in a trunk group belong to the same port group (same ASIC) and run at the same speed. This ensures frame ordering and load balancing across ISLs.
Distractors:
A: Incorrect --- cable length differences must be minimal, but not stated in meters like this.
C: Incorrect --- speeds must match across all trunked ports.
D: Trunking requires a license on some Brocade models; not always enabled by default.
Key Concept: Port trunking requires same port group and same speed.
Your customer has deployed an HPE Alletra MP B10000 array in its virtualized environment. Data protection follows 3-2-1 best practices, with snapshots on the array, Veeam v12 backups, and storage on an external HPE StoreOnce appliance. Despite this, a ransomware attack made data recovery impossible.
Your customer asks how to enhance data protection with immutability and application consistency.
What is a possible solution using HPE Virtual Lock technology?
Detailed Explanatio n:
Rationale for Correct Answe r:
Option C is correct because HPE StoreOnce Virtual Lock technology provides immutability at the Catalyst store level, preventing backup data from being deleted or modified for a defined retention period. This ensures ransomware or malicious actors cannot encrypt, alter, or delete the protected backups, aligning with modern data protection requirements for immutability and compliance. In integration with Veeam v12, backups stored on StoreOnce Catalyst stores can be locked, creating an additional immutability layer beyond application-consistent snapshots.
Analysis of Incorrect Options (Distractors):
A: Virtual Lock is not a Veeam feature. While Veeam v12 supports immutability on certain storage backends (object lock-enabled S3, hardened Linux repositories), HPE Virtual Lock is specific to StoreOnce Catalyst stores, not Veeam job settings.
B: VMware vCenter datastores do not have a native immutability feature. Snapshots in vCenter can be deleted or corrupted during ransomware events, making this option incorrect.
D: HPE Alletra arrays support application-consistent snapshots and replication, but they do not provide the immutability guarantee that StoreOnce Virtual Lock enforces. Array-level snapshots can still be deleted if admin credentials are compromised.
Key Concept:
This question targets knowledge of HPE StoreOnce Virtual Lock --- a feature designed to enforce immutability on Catalyst backup stores, making backup data resistant to deletion or alteration during ransomware or insider attacks.

The storage solution based on the exhibit is deployed at a customer site.
How can the sequential read performance be enhanced with this setup?
Detailed Explanatio n:
Rationale for Correct Answe r:
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 410 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.
A customer is replacing their HPE 3PAR 8200 Peer Persistence setup with Alletra 6000. In a recent audit, they were warned that the Quorum Witness VM was missing security updates.
How would you respond regarding the new setup?
Detailed Explanatio n:
Rationale for Correct Answe r:
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.
Your customer is a software development company using Kubernetes, Canonical, and Tanzu. They are expanding their Dev/Ops container environment and are considering HPE Private Cloud Business Edition (PCBE).
What is a unique benefit that HPE PCBE would bring to this customer's environment?
Detailed Explanatio n:
Rationale for Correct Answe r:
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.
