                  HPE Network Data Center Professional Architect Exam Sample Questions (Q74-Q79):

                  NEW QUESTION # 74
                  Your long-time customer has just acquired a company with 3,500 employees and they are planning on bringing the new data center sites up to their standards. They have asked for a bill of materials given only locations and port counts at the data center sites. What are valid assumptions that should be documented in the proposal? (Choose two.)

                  Answer: A,E

                  Explanation:
                  With only locations and port counts, the proposal should document infrastructure assumptions that affect deployability, such as whether the existing structured cabling and power capacity can support the proposed equipment.


                  NEW QUESTION # 75
                  To prepare for a data center network implementation, you have asked a customer for a list of VLANs to support. The customers list for several VMware ESXi hosts includes 4095. What follow up question should you ask?

                  Answer: A

                  Explanation:
                  In VMware ESXi, VLAN ID 4095 on a port group means VLAN trunking/VGT, allowing guest VMs to tag traffic themselves. You need to identify the actual VLAN tags used by those VMs.


                  NEW QUESTION # 76
                  A customer is deploying a cluster of twelve servers running AI workloads. Each server has four NVIDIA GPUs connected with NVLink. Each server supports 400 GbE connectivity on up to six ports; however, you can recommend using fewer ports. You have been asked to design a network to for the server's backend AI interconnect. Based on HPE Networking 'ecommendations for this workload, how many CX 9300-32D switches should you propose?

                  Answer: D

                  Explanation:
                  For AI backend interconnects, HPE recommends a rail-optimized design with one 400GbE rail per GPU/NIC path. With 4 GPUs per server, propose 4 CX 9300-32D switches, each serving one rail across the 12 servers.


                  NEW QUESTION # 77
                  During requirements gathering, the customer's application owner states RTO must be under 60 seconds for a critical database cluster. Which network-level design decision most directly supports this requirement?

                  Answer: C

                  Explanation:
                  Sub-minute RTO requirements call for fast-converging designs - BFD paired with dynamic routing for rapid link/node failure detection, and VSX for sub-second failover at the access layer - rather than default STP timers or manual intervention, which are far too slow.


                  NEW QUESTION # 78
                  A customer's security team requires micro-segmentation down to the individual workload level within the data center. Which technology combination best satisfies this requirement in an Aruba CX + VMware environment?

                  Answer: D

                  Explanation:
                  NSX's distributed firewall enforces security policy at the vNIC/workload level regardless of physical topology, while the CX VXLAN/EVPN fabric provides the underlying transport. VLANs alone can't achieve workload-level granularity, physical firewalls per server pair are impractical, and disabling east-west traffic breaks application functionality.
