                  HPE Network Data Center Professional Architect Exam Sample Questions (Q87-Q92):

                  NEW QUESTION # 87
                  You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN with a distributed gateway model. You are helping implementers to assemble a list of required loopback interface IDs and IP blocks. What information do you need from the customer to complete this list?

                  Answer: D

                  Explanation:
                  The choice of single-AS versus dual-AS affects the BGP control-plane configuration and AS numbering, not principally the required loopback inventory. Distributed-gateway designs can require dedicated per-VRF loopback addressing for services such as DHCP relay and unique source addressing. HPE also recommends planning an IP block for the loopbacks assigned to each overlay VRF.


                  NEW QUESTION # 88
                  You are planning a pair of CX switches to act as ToR switches. The switches implement VSX as part of a data center L2 topology and connect to the core on VSX LAGs. To meet expansion requirements, you need to keep as many ports open as possible. What option should you recommend for VSX LAGs?

                  Answer: A

                  Explanation:
                  VSX keepalives should use an independent path from the ISL. Using the OOBM management interface preserves front-panel data ports while still providing a separate keepalive path.


                  NEW QUESTION # 89
                  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: A

                  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 # 90
                  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: C

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


                  NEW QUESTION # 91
                  What is the primary purpose of conducting a "current state assessment" before beginning a data center network design?

                  Answer: C

                  Explanation:
                  A current state assessment creates a factual baseline (topology, traffic flows, capacity, known issues) that the new design must account for or improve upon. It is not a substitute for interviews, nor should it precede requirements gathering in the overall process, nor is it a sales tool.


                  NEW QUESTION # 92
                  ......
