Two HPE Storage Alletra MP B10000 arrays are deployed with Active Peer Persistence. Both arrays and hosts are installed in close proximity to each other. To enable symmetric access, Peer Persistence must be configured accordingly.Which Host Proximity Parameter should be selected for host ESX31 in this case?
Answer(s): B
Detailed Explanation;Rationale for Correct Answer;Option B (All) is correct because in an Active Peer Persistence deployment where both arrays and hosts are in close proximity (metro or campus cluster scenario), the hosts should be configured with Host Proximity = All. This ensures that the host (ESX31) can access both arrays symmetrically and concurrently, enabling active-active paths. This is essential to deliver seamless failover and load balancing across the arrays in an HPE Alletra MP Peer Persistence environment.Analysis of Incorrect Options (Distractors):A (Secondary): This is used for hosts located closer to the secondary array, to bias access toward it in asymmetric deployments. Not applicable here since the hosts are near both arrays. C (Exclusive): This option assigns the host to a single array exclusively, preventing dual-active access. This would defeat the purpose of symmetric Peer Persistence. D (Primary): Similar to Secondary, this biases access to only the primary array, which is not correct when arrays and hosts are in the same site for active-active.Key Concept:This question focuses on Host Proximity parameters in HPE Peer Persistence. Primary/Secondary = asymmetric designs (hosts closer to one array). All = symmetric design (hosts equidistant to both arrays, enabling active-active).Exclusive = restricts access to one array only.

While attempting to increase an upstream volume size for an Alletra 6000 Peer Persistence setup from local web management, you are facing an error that prevents you from completing the task. Which action is required to complete the task successfully?
Answer(s): C
Detailed Explanation;Rationale for Correct Answer;In Alletra 6000 Peer Persistence environments, operations like resizing Peer Persistence volumes must be performed via the HPE Data Services Cloud Console (DSCC), which manages volume collections and replication consistency groups. Attempting to grow the upstream volume locally will fail because the changes need to propagate across both sites consistently.Distractors:A/B: Removing upstream or downstream volumes would break replication and is not required.D: Expanding in VMware only extends the VMFS datastore, not the underlying replicated volume. Key Concept: Peer Persistence volume resizing is done in DSCC, not local web GUI.

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?
Answer(s): A
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.

Your customer is using 2 HPE StoreOnce appliances across 2 sites with replication enabled for disaster recovery. They are concerned about the fact that the StoreOnce administrators have full access to the systems, which allows them to delete backup copies on these systems. What needs to be used to address the concern of your customer?
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.

Two HPE Alletra 6000 arrays are configured for peer persistence between datacenters A and B, which have a fiber distance of 50km (31mi). The datacenter B hardware will be relocated to a new location that will increase the fiber distance to 150km (93mi). Which condition is valid once the relocation is finished?
Detailed Explanation;Rationale for Correct Answer;HPE Peer Persistence is supported over distances of up to 150200 km, as long as the round-trip latency is 10ms. Therefore, even after relocation to 150km, Peer Persistence remains supported provided latency requirements are met.Distractors:B: RC (Remote Copy) transport is already the underlying technology, but no change is required.C: Peer Persistence is already an active-active design; no change to "active" mode is needed.D: Distance does not exceed the supported range; only latency matters. Key Concept: Latency <10ms is the critical requirement for Peer Persistence.
