                  HPE Network Data Center Professional Architect Exam Sample Questions (Q14-Q19):

                  NEW QUESTION # 14
                  Hotspot Question
                  Click where you would implement the CX 10000 network segmentation policy in this data center deployment.

                  Answer:

                  Explanation:

                  Explanation:
                  Network segmentation/microsegmentation for server workloads is implemented at the CX 10000 ToR enforcement points, closest to the workloads. The edge gateway is for north-south/WAN edge services, not the primary workload segmentation policy placement.


                  NEW QUESTION # 15
                  Which two are valid reasons to recommend a routed underlay (Layer 3 to the leaf) in a VXLAN/EVPN fabric design? (Choose two.)

                  Answer: B,E

                  Explanation:
                  A routed underlay removes STP dependency and enables ECMP across all spine-leaf paths for deterministic load balancing and fast convergence. It still requires underlay IP addressing, doesn't guarantee zero oversubscription (that's a hardware/design choice), and doesn't eliminate the need for an overlay if one is desired for mobility/segmentation.


                  NEW QUESTION # 16
                  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: D

                  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 # 17
                  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: B

                  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 # 18
                  What is the primary benefit of using EVPN as the control plane for a VXLAN overlay, compared to traditional flood-and-learn VXLAN?

                  Answer: A

                  Explanation:
                  EVPN leverages MP-BGP to advertise MAC and IP host routes proactively between VTEPs, avoiding the flooding and slow convergence associated with traditional flood-and-learn VXLAN. It still requires an underlay and VTEPs, and works with both IPv4 and IPv6.


                  NEW QUESTION # 19
                  ......
