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.

Rationale for Correct Answe r:

HPE Morpheus can run as a single VM in non-critical environments, but for high availability (HA) without distributed databases, the recommendation is to deploy 3 VMs in a cluster. This ensures quorum and redundancy across application nodes, protecting against single VM failure. Distributed database mode requires more VMs, but is not needed in this scenario.

Distractors:

A: 4 VMs are required only if distributed DB is enabled (PostgreSQL cluster), not here.

B/D: A single VM (with or without VMware HA) doesn't provide native Morpheus HA resilience.

Key Concept: Morpheus HA = 3-node cluster minimum without distributed DB.

Rationale for Correct Answe r:

From the exhibit, the system shows maximum estimated IOPS performance (over 250K IOPS read, 115K IOPS mixed, 62K write). These values align with HPE's published performance specifications for this model with full cores enabled. The network interface count and disk count are balanced relative to controller capability. Therefore, no further upgrades are required to achieve maximum performance.

Distractors:

A: Adding NICs/HBAs may improve throughput but will not exceed controller-bound IOPS.

B: Adding disks increases capacity, not peak IOPS, as performance is primarily controller-driven.

D: The system already matches controller capability; upgrading cores is not an option in Alletra MP B10000 mid-range systems.

Key Concept: Understanding performance sizing based on controller and architecture limits, not just capacity or NICs.

Detailed Explanatio n:

Rationale for Correct Answe r:

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.
