                                HPE Network Data Center Professional Architect Exam Sample Questions (Q63-Q68):

                                NEW QUESTION # 63
                                Which two are valid reasons to recommend a routed underlay (Layer 3 to the leaf) in a VXLAN/EVPN fabric design? (Choose two.)

                                Answer: A,C

                                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 # 64
                                What documents should be included in the solution proposal?

                                Answer: C

                                Explanation:
                                A solution proposal should include the proposed equipment and licensing details in a Bill of Materials. As-built diagrams are post-install deliverables, and architect meeting notes are not normally part of the customer-facing proposal.


                                NEW QUESTION # 65
                                You are modernizing a customer's legacy three-tier architecture with an L3 spine and leaf topology. The CX switches in the topology will provide the overlay. The customer data center uses six VRFs. The customer has asked for service leaf switches to connect to two clustered firewalls, which route and filter traffic between the VRFs. How can you maximize the efficiency of the traffic flow between subnets in the same VRF?

                                Answer: D

                                Explanation:
                                For traffic between subnets in the same VRF, distributed L3 anycast gateways allow routing directly at the leaf switches, avoiding inefficient hairpinning through centralized firewalls. The firewalls should be used for routed/filtering traffic between VRFs.


                                NEW QUESTION # 66
                                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: B

                                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 # 67
                                To secure the network, which feature or capability should be implemented?

                                Answer: C


                                NEW QUESTION # 68
