                  HPE Network Data Center Professional Architect Exam Sample Questions (Q22-Q27):

                  NEW QUESTION # 22
                  You are designing an L3 spine and leaf architecture for a customer based on CX 10000 Series switches as leaf switches. The customer has added a requirEMENT that the leaf switches also support servers' iSCSI adapters. You have verified your design also meETS The customer's needs for lossless iSCSI. The customer asks for advice on ensuring that THE East-west firewall permits the iSCSI traffic. What should you explain?

                  Answer: C

                  Explanation:
                  lOSSLess iSCSI traffic uses a no-drop PFC queue, and CX 10000 dsm East-west firewall services are not applied to traffic in that queue. Therefore, no firewall permit rule is required for that traffic.


                  NEW QUESTION # 23
                  Which documents should be included in the solution proposal? Choose two.

                  Answer: A,D


                  NEW QUESTION # 24
                  Your long-time customer has just acquired a company with 3,500 employees and they are planning on bringing the new data center sites up to their standards. They have asked for a bill of materials given only locations and port counts at the data center sites. What are valid assumptions that should be documented in the proposal? (Choose two.)

                  Answer: B,D

                  Explanation:
                  With only locations and port counts, the proposal should document infrastructure assumptions that affect deployability, such as whether the existing structured cabling and power capacity can support the proposed equipment.


                  NEW QUESTION # 25
                  You are planning a network upgrade for a VMware-virtualized data center. The customer already uses NSX.
                  You are responsible for the CX switch design, and the customer is responsible for the NSX design.
                  What is one topic to discuss for the logical design?

                  Answer: B

                  Explanation:
                  When integrating an HPE ArubaOS-CX physical network fabric with an existing software-based overlay network such as VMware NSX, clear demarcation of network control planes is critical. In this architectural split, VMware NSX manages the logical GENEVE/VXLAN encapsulation across its host Edge nodes and transport nodes, while the Aruba CX switching fabric operates as the underlying Layer 3 IP transport network.
                  The primary logical interface between these two domains occurs at the border handoff, specifically involving the NSX Tier-0 Gateways and the physical CX switches (typically border leaves or core nodes). The architect must discuss and establish the routing design (typically dynamic eBGP peering over dedicated VLANs or routed links) to govern north-south reachability between subnets residing within the NSX overlay and systems residing outside the overlay (such as bare-metal database servers, external campus users, and WAN/Internet edges). Mapping internal VLANs to VNIs or defining overlay VRFs are functions executed strictly within the NSX software fabric.

                  NEW QUESTION # 26
                  A customer's data center has 40 racks and is growing. The customer asks you to recommend a fabric topology that supports predictable latency and easy horizontal scaling. Which topology should you recommend?

                  Answer: D

                  Explanation:
                  A spine-leaf (Clos) fabric provides consistent, predictable latency between any two leaf switches (every leaf is equidistant from every other leaf through the spine) and scales horizontally by adding spine or leaf switches without redesigning the fabric. Three-tier designs introduce variable latency and are harder to scale predictably; ring and full-mesh access designs don't fit modern DC scale requirements.


                  NEW QUESTION # 27
