HP Advanced HPE Storage Integrator Solutions Written Exam Sample Questions (Q20-Q25):NEW QUESTION # 20
Your organization is implementing a new high-performance computing (HPC) cluster to support advanced scientific simul-ations. The cluster will consist of several hundred nodes that require rapid access to shared datasets. The storage is Vast/GL4F.
The application is very sensitive to latency and minimizing CPU overhead during data transfers is critical to achieving the desired performance levels.
Which access protocol should the organization implement to enhance NFS performance by reducing storage latency and increasing I/O operations?
  • A. NFS
  • B. iSER
  • C. NFS over RDMA
  • D. RoCE
Answer: C
Explanation:
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.
Reference: HPE GreenLake for File Storage powered by VAST - HPC Deployment Guide, RDMA and NFS performance white papers.

NEW QUESTION # 21
A mid-sized enterprise needs a file storage solution that offers scalable storage and integrated data protection, backup, and disaster recovery.
Which solution best meets the company's needs?
  • A. HPE GreenLake for File Storage
  • B. Cohesity
  • C. Qumulo
  • D. Scality
Answer: A
Explanation:
Detailed Explanation:
Rationale for Correct Answer:
HPE GreenLake for File Storage (powered by VAST Data) delivers scale-out NAS capabilities with native data protection, snapshots, and disaster recovery integration. It is designed for enterprises that need both scalability and integrated protection in a single consumption or CapEx model.
Distractors:
A (Qumulo): Excellent scale-out file, but lacks deep HPE ecosystem integration.
B (Scality): Primarily focused on object storage, not file workloads.
D (Cohesity): Strong in backup and secondary storage, but not primary enterprise file services.
Key Concept: HPE GreenLake for File Storage = enterprise-grade file storage + integrated protection.
Reference: HPE GreenLake for File Storage Overview.

NEW QUESTION # 22
You are sizing an HPE Alletra 5030. Unless otherwise indicated by the HPE sizer or the customer's requirements, HPE best practices state that you should default to which minimum FDR calculation?
  • A. 23% of the largest drive size
  • B. 23% of the smallest drive size
  • C. Above 12% for low-read latency
  • D. Below 12% for low-read latency
Answer: A
Explanation:
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.
Reference: HPE Alletra 5000/6000 Sizing and Configuration Guide.

NEW QUESTION # 23
An HPE Alletra 6030 with 138TB flash kit needs a storage expansion. The BOM lists only a 46TB Expansion Shelf, including price.
What should you take into account?
  • A. Total supported capacity will be exceeded with the proposed configuration.
  • B. QSFP+ DAC cables are required if NVMe media is used.
  • C. The expansion shelf needs to include the 24G SAS cables.
  • D. Both Controllers need 100Gb OCP adapters for the expansion shelf connection.
Answer: C
Explanation:
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.
Reference: HPE Alletra 6000 Hardware Installation Guide.

NEW QUESTION # 24
Refer to the exhibit.

Your customer had an unexpected failure of their current storage array, causing them to lose some of their critical data. As a result, they are looking for a storage array with a guarantee of 100% data availability to prevent this failure and loss in the future.
They need 80TB raw and two new 25GbE top-of-rack switches to connect to their environment.
They expect 5% annual growth.
Which correction should be made to the configuration in the exhibit to meet the customer's requirements?
  • A. Add 2× Aruba 8325 switches
  • B. Decrease to 20 × 3.84TB drives
  • C. HPE GreenLake financial model
  • D. Change to 25G networking
Answer: D
Explanation:
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.
Reference: HPE Alletra MP Ordering and Configuration Guide.
