HPE0-J82 Sample Questions

  1. Question 1

    Advanced

    Differentiate and apply foundational storage architectures and technologies · Describe multi-site data availability methods and technologies

    A financial institution is designing a disaster recovery architecture across two data centers located 45 kilometers apart. The business mandates an RPO of zero and an RTO of less than 5 minutes for their tier-1 transactional databases. They have a dark fiber connection with less than 2ms round-trip latency between the sites.

    Which replication technology and architecture should the storage architect recommend to meet these strict requirements without manual intervention during a failover?

    sequenceDiagram participant Host participant SiteA as Primary Array participant SiteB as Secondary Array Host->>SiteA: Write Request SiteA->>SiteB: Replicate Data SiteB-->>SiteA: Acknowledge SiteA-->>Host: Write Complete
    Answer and explanation

    Correct answer: D

    For an RPO of zero, synchronous replication is strictly required. To achieve an RTO of less than 5 minutes without manual intervention, an active-active or stretched cluster architecture (like HPE Peer Persistence with an automatic quorum witness) is necessary. The latency of <2ms over 45km easily supports the synchronous round-trip requirement.

  2. Question 2

    Beginner

    Differentiate and apply foundational storage architectures and technologies · Describe and evaluate the use of drive interconnect technologies

    When comparing NVMe to traditional SAS interconnects in a modern all-flash storage array, which architectural difference provides NVMe with significantly lower latency and higher throughput?

    Answer and explanation

    Correct answer: A

    NVMe (Non-Volatile Memory Express) was designed specifically for flash media. It attaches directly to the PCIe bus, eliminating the translation overhead required by SAS/SATA controllers, and supports up to 64K queues with 64K commands per queue.

  3. Question 3

    Intermediate

    Differentiate and apply foundational storage architectures and technologies · Describe Storage presentation to hosts

    A system administrator is configuring host presentation for a new ESXi cluster connected to an active-optimized/active-unoptimized storage array. Which industry-standard protocol must the multipathing software support to dynamically discover optimal vs. non-optimal paths?

    Answer and explanation

    Correct answer: B

    ALUA (Asymmetric Logical Unit Access) is a SCSI standard that allows an array to communicate path states (Active/Optimized, Active/Non-Optimized, Standby, Unavailable) to the host multipathing software (like VMware NMP/PSP_RR), ensuring IO is sent down the most efficient controller paths.

  4. Question 4

    Intermediate

    Differentiate and apply foundational storage architectures and technologies · Describe and characterize the different SAN topologies

    An organization is redesigning its Fibre Channel SAN to support 2,000 servers and 4 enterprise storage arrays. They require high scalability, predictable performance for storage traffic, and simplified management. Which SAN topology best meets these requirements?

    Answer and explanation

    Correct answer: A

    A Core-edge topology connects servers to edge switches and storage to core switches. This provides high scalability, limits the number of hops (predictable performance), and simplifies management compared to deeply cascaded or full-mesh topologies at large scale.

    graph TD subgraph Edge Layer S1[Server 1] --> E1[Edge Switch 1] S2[Server 2] --> E2[Edge Switch 2] end subgraph Core Layer E1 --> C1[Core Director A] E2 --> C1 C1 --> ST1[(Storage Array)] end

  5. Question 5

    Beginner

    Differentiate and apply foundational storage architectures and technologies · Describe data availability and resiliency methodologies

    A customer needs to store 500 TB of unstructured archive data. They require high data durability capable of surviving multiple simultaneous drive failures, but they are extremely constrained by budget and physical rack space. Which data resiliency methodology provides the highest usable capacity relative to raw capacity while maintaining high fault tolerance?

    Answer and explanation

    Correct answer: D

    Erasure coding breaks data into fragments, expands them with redundant data pieces, and stores them across a set of different locations. It provides higher fault tolerance (can survive multiple failures depending on the configuration) with significantly less capacity overhead compared to mirroring (RAID 10), making it ideal for large-scale archive data where space and cost are constrained.

  6. Question 6

    IntermediateMultiple answers

    Differentiate and apply foundational storage architectures and technologies · Identify Storage optimization technologies

    A storage architect is evaluating which workloads to place on a newly deployed storage array featuring inline deduplication and compression. Which TWO of the following workloads will typically yield the highest data reduction ratios? (Select TWO)

    Answer and explanation

    Correct answers: A, C

    VDI full clones contain highly identical operating system files across hundreds or thousands of instances, resulting in excellent deduplication ratios.

    Server virtualization datastores typically host multiple VMs with similar OS binaries and templates, providing high deduplication and compression efficiency.
