                                HPE Network Data Center Professional Architect Exam Sample Questions (Q69-Q74):

                                NEW QUESTION # 69
                                A customer's data center is expanding from one row to five rows over the next two years. What design principle should guide the initial fabric design to support this growth?

                                Answer: B

                                Explanation:
                                A modular spine-leaf design allows incremental scale-out (adding leaves/racks) without re- architecting the fabric, which is essential when the customer has known growth plans. Designing only for the current state, or ignoring growth plans, risks a costly redesign later.


                                NEW QUESTION # 70
                                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: B

                                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 # 71
                                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 # 72
                                The customer operates a 24/7 production facility and is concerned that the migration will disrupt the production line. What are two ways to minimize or eliminate this disruption? (Choose two.)

                                Answer: A,D

                                Explanation:
                                To minimize disruption in a 24/7 environment, build the new infrastructure in parallel where possible and migrate gradually. Replacing one access switch at a time with a detailed patch plan limits the impact to small, controlled sections.


                                NEW QUESTION # 73
                                A customer has a highly virtualized data center for which you are designing a two-tier L2 data center. What are the characteristics of a design that extends VLANs only to the ToR switches and server ports that strictly need those VLANs? (Choose two.)

                                Answer: B,E

                                Explanation:
                                Limiting VLANs only to required ToR switches and server ports reduces unnecessary Layer 2 flooding/MAC learning and gives network admins tighter control over where each VLAN exists. It is less flexible for server admins than extending all VLANs everywhere.


                                NEW QUESTION # 74
                                ......
