                  HPE Network Data Center Professional Architect Exam Sample Questions (Q25-Q30):

                  NEW QUESTION # 25
                  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 # 26
                  You have designed a spine and leaf topology, which includes 16 leaf switches and four spine switches. The customer has no existing overlay solution. You are helping the implementer work with the customer to obtain IP address blocks for the design. You plan to ask for these /24 subnets. One for an individual loopback interface for each switch. One for point-to-point connections between leaf and spine switches. What is one of the corrections you must make?

                  Answer: A

                  Explanation:
                  In an EVPN-VXLAN spine-leaf design with VSX leaf pairs, you need individual loopbacks for switch identity/control-plane functions and an additional shared loopback per VSX pair for the common VTEP/anycast function.


                  NEW QUESTION # 27
                  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 # 28
                  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: A

                  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 # 29
                  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.
