                  HPE Network Data Center Professional Architect Exam Sample Questions (Q45-Q50):

                  NEW QUESTION # 45
                  What are important characteristics to mention while discussing possible connections for VMware hosts to server-access-switches?

                  Answer: C

                  Explanation:
                  VMware hosts can use LACP only when the required vSphere features/licensing are available, typically with a vSphere Distributed Switch. This is important when designing host-to-access- switch connectivity.


                  NEW QUESTION # 46
                  During the design validation phase, you propose a "proof of concept" (PoC) lab test before full production deployment. What is the primary value of a PoC in this context?

                  Answer: A

                  Explanation:
                  A PoC validates critical assumptions -- such as failover timing, third-party interoperability, or new feature behavior -- in a low-risk environment before full deployment, reducing production risk. It doesn't guarantee zero issues, isn't a legal requirement, and doesn't replace design documentation.


                  NEW QUESTION # 47
                  Waratah Hospital, based in Australia, is planning to move many data center services to new facility. (The remaining legacy data center will not be part of this project.) Waratah Hospital hired an external consultant to assist with the new data center network design.
                  Based on the requirements for the data center network infrastructure, the external consultant has created a high-level design. The below summarizes the content of the design document.
                  Requirements and information:
                  - Six racks in the data center room (single row).
                  - Redundant Top of Rack leaf switches with back-to-front cooling in each rack, providing 10/25 Gbps connectivity to servers, storage, and other devices.
                  - Four 100 GbE uplinks per leaf switch.
                  - The customer requested to install all switch ports facing the back of the rack racks (hot aisle.)
                  - OOB management for servers, storage, and network has to be provided through an external switch with back-to-front cooling. This switch has to be included in the solution. One OOB switch provides connectivity for two racks.
                  - Core equipment for the OOBM network is being reused.
                  - Middle-of-row spine switches.
                  -The data center should connect to the hospital building with links that provide 400 Gbps.
                  - Internet access is provided through an existing firewall cluster with two firewalls, each firewall in one data room. The second firewall is operating in standby mode, VRRP is utilized on the firewalls for failover. The data center network should connect to these firewalls with links that total
                  100 Gbps.
                  - The external link is a dark fiber direct link based on single-mode fiber (OS2). The distance to the main hospital 1.5 KM. The links will terminate on two core switches in the hospital.
                  The customer also requires:
                  - 99.999% uptime for this life-critical environment.
                  - Planned and unplanned downtime has to be minimized.
                  - Software upgrades are only allowed once per year with close to zero downtime.
                  - All life-critical resources are accessed locally, and all resources exist within the hospital campus.
                  - Waratah Hospital requires a highly secure environment for the data center. Encrypted wire speed connectivity between the data room and the hospital is a must-have because the link between the buildings crosses a public road.
                  - Waratah Hospital has a mix of virtualized (vSphere) servers. Nutanix storage, bare metal servers, backup servers and other devices.
                  In the past, the hospital has had a security breach that resulted in data loss, network downtime, and identity theft.
                  Refer to the scenario. You have learned that the customer needs to extend two VRFs between the new data center facility and the hospital. To meet with the requirements of the scenario and general best practices, what should you recommend for connecting border leaf switches to the hospital core?

                  Answer: C

                  Explanation:
                  This provides 400Gbps total, full-mesh resiliency, and separate routed connectivity for the two VRFs.


                  NEW QUESTION # 48
                  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,C

                  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 # 49
                  You are planning a CX-based data center network that applies east-west firewall policies, managed by AMD Pensando Policy and Services Manager (PSM). Which network should be used to communicate with PSM?

                  Answer: B

                  Explanation:
                  PSM is a management/control system for CX 10000 distributed services, so switch-to-PSM communication should use the out-of-band management network, separate from the data underlay and overlay traffic.


                  NEW QUESTION # 50
                  ......
