                                HPE Network Data Center Professional Architect Exam Sample Questions (Q48-Q53):

                                NEW QUESTION # 48
                                What is a key reason to interview the customer's storage team during data center network design, even if the network team owns the project?

                                Answer: D

                                Explanation:
                                Storage protocols often have specific network requirements -- for example, NVMe-oF or FCoE may require lossless (DCB/PFC) Ethernet, iSCSI may need dedicated VLANs, and FC may need separate SAN fabrics -- all of which must be reflected in the network design.


                                NEW QUESTION # 49
                                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: D,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 # 50
                                You are sizing spine switches for a new leaf-spine fabric supporting 48 leaf switches, each with two 100G uplinks. What is the minimum number of 100G ports required per spine switch if there are 4 spine switches and full redundancy is desired?

                                Answer: C

                                Explanation:
                                Each leaf has 2 uplinks distributed across 4 spines (1 uplink to 2 of the 4 spines, or evenly spread), so each spine needs to support 48 leaves รท 4 spines ร— 2 uplinks = 24 ports per spine to provide full connectivity and redundancy.


                                NEW QUESTION # 51
                                Which information should you attempt to discover during your first data center network design meetings with the customer? (Choose two.)

                                Answer: A,B

                                Explanation:
                                Early design meetings should establish key project context and constraints, such as whether the deployment is greenfield or brownfield and the available project budget. Detailed switch sizing and training planning come later.


                                NEW QUESTION # 52
                                In multi-fabric design, what is the minimal recommended MTU?

                                Answer: D

                                Explanation:
                                Multi-fabric EVPN/VXLAN designs require jumbo MTU for encapsulation overhead, and HPE Aruba validated configurations commonly use MTU 9198 on AOS-CX links/interfaces.


                                NEW QUESTION # 53
                                ......
