                  HPE Network Data Center Professional Architect Exam Sample Questions (Q81-Q86):

                  NEW QUESTION # 81
                  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: A

                  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 # 82
                  Which two are valid reasons to recommend a routed underlay (Layer 3 to the leaf) in a VXLAN/EVPN fabric design? (Choose two.)

                  Answer: B,E

                  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 # 83
                  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: A,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 # 84
                  Refer to the exhibit.

                  You are designing a data center network. This customer requests that you connect the data center core their firewalls. The customer uses six VRFs for segmentation, and the firewalls are responsible for handling traffic in all of the VRFs.
                  What is the recommended design for the links between the data center core switches and the firewalls?

                  Answer: A

                  Explanation:
                  From the exhibit:
                  1. Links 1 and 3 connect the two VSX core switches to the active firewall.
                  2. Links 2 and 4 connect the two VSX core switches to the passive firewall.
                  Therefore, each firewall receives its own VSX multi-chassis LAG.


                  NEW QUESTION # 85
                  What is the best practice for using VSX at the Core of a two-tier design?

                  Answer: C

                  Explanation:
                  In a two-tier L2 access design, VSX at the core provides redundant active-active connectivity and default gateway resiliency for access switches. For L3-only or EVPN-VXLAN access designs, routed spine/core behavior is preferred instead.
