Free HPE Storage Architect (HPE0-J82) Practice Questions

Answer : C

The HPE Ninja Online Block Storage Sizer is the product-aligned planning tool for an HPE Alletra 5000 block storage solution. Alletra 5000 uses adaptive flash technology, combining HDD storage capacity with SSD-based acceleration, so a correct recommendation must consider both usable capacity and sustained workload performance. The sizer supports collection of workload characteristics such as logical dataset size, I/O rates, throughput, latency requirements, future growth and expected data reduction. The architect should compare proposed drive, cache and controller resources with expected mixed-workload patterns rather than assuming the largest capacity configuration has the best response time. NinjaSTARS serves specialized storage sizing workflows; the Intelligent Configurator focuses on configuration tasks; and CloudPhysics supplies infrastructure metadata and assessment insight. None replaces the identified block-storage sizing workflow for this question. Current application data should be collected wherever possible; otherwise document assumptions explicitly. Final output needs validation against HPE QuickSpecs, supported expansion rules, and any customer availability or replication obligations.

Answer : B

For the HPE Alletra 5030-to-5050 upgrade scenario, HPE's placement guidance recommends the largest-capacity disks in the head shelf and then the nearest expansion shelves. The adaptive flash system combines HDD capacity and SSD cache, so both physical layout and cache placement can influence operating characteristics and supported expansion behavior. Where different cache capacities are present, the higher cache capacity belongs in the head shelf rather than a distant expansion shelf. Placing the lowest cache capacity there, as option A states, reverses that recommendation. Option C unnecessarily demands an absolute same-capacity rule for every disk in a shelf, and D places the largest cache in the first expansion shelf instead of the head shelf. Before changing controllers or disks, the architect should verify current drive distribution, cache tiers, firmware, enclosure order, and allowed upgrade path. Expected mixed-workload performance improvements should be evaluated with IOPS, latency, throughput, and growth estimates rather than controller model numbers alone.

Answer : B

Effective capacity is the correct basis for HPE Alletra Storage MP B10000 capacity modeling in Ninja Online Block Storage Sizer because it represents the amount of logical customer data accommodated after applying supported space-efficiency mechanisms. HPE's architecture includes thin provisioning, compression, deduplication and efficient copies. Raw capacity counts installed flash before protection and system overhead; usable capacity represents the physical capacity available after relevant reservations; installed capacity merely describes purchased media. These values do not by themselves describe the logical application data that may fit after data reduction. The B10000 QuickSpecs use an illustrative 4:1 compaction assumption with RAID 6 and operational headroom, while warning that real ratios depend on workload. Therefore sizing requires estimates of non-reducible data, application growth, snapshots and protection obligations. An effective-capacity figure should not be treated as an unconditional guarantee for all datasets. An architect should retain the workload assumptions and validate them with customer telemetry or representative data samples before finalizing a purchase.

Answer : D

NVMe over Fabrics (NVMe-oF) is the backend protocol family used for high-speed access between the disaggregated elements of switched HPE Alletra Storage MP systems. Separate controller chassis provide processing while NVMe JBOF shelves supply flash capacity. Dedicated redundant Ethernet switching carries storage commands to the shared media, enabling independent scaling of compute and raw flash resources. NVMe-oF preserves the efficient NVMe command model across a fabric, reducing overhead associated with remote flash access. Although Fibre Channel and iSCSI can serve host connectivity in enterprise designs, they are not the specified interconnection for the switched MP backend. 'FC-oF' is not the required protocol label. Implementation must respect dedicated backend switch models, port requirements, cabling symmetry, redundancy and release-specific support matrices. The system's ability to survive selected component failures also depends on maintaining all intended alternate paths. For the requested controller interconnection technology, NVMe-oF is the correct architectural description. Failure tests should confirm continued backend accessibility after a supported fabric component outage.

Answer : D

HPE Alletra Storage MP B10000 QuickSpecs identify up to two front-end 100 GbE iSCSI or NVMe/TCP ports per supported controller node, with the precise capability determined by model, adapter selection, ArcusOS release, and age of the configuration. Host-facing Ethernet connectivity must be distinguished from the redundant high-speed backend links used for JBOF access and controller/storage interconnection. A front-end port connects an array to the customer's host-storage network, while an expansion port belongs to the internal storage fabric. HPE's published B10000 specification does not support the four front-end 100 GbE connections claimed by the uploaded answer key. Four front-end 100 GbE ports may be associated with different HPE storage platforms, including X10000 configurations, but that must not be transferred to the B10000 specification. The question therefore illustrates the need to read product-specific QuickSpecs rather than infer port quantities from adapter speed or the number of visible physical connectors. Under the cited B10000 specification, D is supported.
