                  HPE Network Data Center Professional Architect Exam Sample Questions (Q21-Q26):

                  NEW QUESTION # 21
                  During a design workshop, the customer states their applications are highly sensitive to latency and jitter, such as real-time market data feeds. What design change might you propose?

                  Answer: C

                  Explanation:
                  Latency-sensitive workloads benefit from a low-oversubscription, cut-through-capable spine-leaf fabric with minimal hop count; PTP (Precision Time Protocol) support may also be relevant for timestamp-sensitive financial applications. Adding tiers or reducing spines would increase latency or reduce resiliency.


                  NEW QUESTION # 22
                  A customer running VMware with NSX asks whether they still need to design VLANs on the physical CX switches. What is the correct guidance?

                  Answer: C

                  Explanation:
                  Even with NSX handling overlay segmentation for workloads, the physical underlay still requires basic VLANs/subnets for functions like VTEP/transport connectivity and out-of-band management; NSX segments do not need to map one-to-one with physical VLANs, and a pure L2 underlay is not required (a routed underlay is typically preferred).


                  NEW QUESTION # 23
                  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.
                  Given the scenario, which environmental requirements are provided in this scenario? (Choose two.)

                  Answer: D,E

                  Explanation:
                  The scenario provides switch placement requirements and airflow direction, including back-to- front cooling and ports facing the hot aisle.


                  NEW QUESTION # 24
                  Your customer requires management access to switches through SSH. Which authentication mechanism can be implemented?

                  Answer: D

                  Explanation:
                  SSH management access can be authenticated against an external directory using secure LDAP/LDAPS, allowing centralized user authentication for switch administration.


                  NEW QUESTION # 25
                  A customer wants to know how their new EVPN VXLAN fabric will interoperate with their existing WAN edge routers, which only support traditional VLAN trunks. What is an appropriate design element to bridge this gap?

                  Answer: B

                  Explanation:
                  Border leaf switches are designed to bridge overlay VXLAN networks to traditional VLAN-based external networks (such as legacy WAN edge routers), avoiding the need to replace or upgrade those devices as a prerequisite.
