                  HPE Network Data Center Professional Architect Exam Sample Questions (Q62-Q67):

                  NEW QUESTION # 62
                  You delivered an L3 spine and leaf topology to a customer several years ago. The solution consisted of two CX 8325-32C switches at the spine and 20 CX 8325-48Y8C leaf switches. The leaf switches operate as 10 VSX pairs. The customer would now like to double the forwarding capacity of the topology. What should you recommend?

                  Answer: D

                  Explanation:
                  The current design has 2 spine switches, with each leaf connecting to each spine. Adding 2 more spines doubles the number of ECMP spine paths and therefore doubles the leaf-to-spine forwarding capacity, while staying within CX 8325-32C port limits.


                  NEW QUESTION # 63
                  Which factor should most influence the decision to use a two-tier (spine-leaf) versus a three-tier (spine-super spine-leaf) fabric design?

                  Answer: D

                  Explanation:
                  When the required scale exceeds what a single spine tier can support (i.e., more leaf switches than available spine ports allow), a super-spine tier is introduced to interconnect multiple spine- leaf "pods," forming a three-tier design. Scale, not aesthetics or unrelated org details, drives this decision.


                  NEW QUESTION # 64
                  You have been called in to help design an HPE Aruba Networking CX network solution to connect AI servers to file storage. The solution must support NFS over RDMA and provide 400 GbE links to the edge. The design currently consists of leaf and spine switches, which carry all traffic in VXLAN tunnels. Each switch is a CX 9300-32D switch. What is one correction that you should make to the design?

                  Answer: D

                  Explanation:
                  NFS over RDMA/RoCE requires lossless Ethernet behavior with DCB features such as PFC/ETS and ECN. For CX 9300-based RoCE designs, ECN is supported in the underlay, not in the VXLAN overlay, so RDMA storage traffic should not be carried through VXLAN tunnels.


                  NEW QUESTION # 65
                  You are designing a CX data center network for a customer who has indicated that they must integrate the switches in their automation workflows. Which capability enables your customer to fulfill their objectives?

                  Answer: B

                  Explanation:
                  Aruba CX switches support automation through a REST API using JSON, which enables integration with external automation/orchestration workflows.


                  NEW QUESTION # 66
                  A customer wants each of their three data centers to be able to fail over workloads to either of the other two sites. Which network design approach best supports this "any-to-any" DR model?

                  Answer: C

                  Explanation:
                  Extending an EVPN VXLAN fabric across all three sites via a DCI allows any site to serve as an active or standby location for any workload, providing symmetric any-to-any failover. Hub-and- spoke and isolated designs don't support symmetric multi-site failover, and static routing doesn't scale for this use case.


                  NEW QUESTION # 67
                  ......
