HPE Network Data Center Professional Architect Exam Sample Questions (Q73-Q78):

NEW QUESTION # 73
A customer's network team is hesitant to adopt Fabric Composer because they are comfortable with CLI-based management. What is an effective way to address this concern in the design proposal?

Answer: D

Explanation:
Addressing organizational change resistance requires a phased plan with training, and reassurance that CLI access remains available for troubleshooting even as Fabric Composer provides intent-based automation for routine operations - balancing new capability with familiar workflows.


NEW QUESTION # 74
You have been called in to help design an HPE Aruba Networking CX network solution to connect AI servers to file storage. The solution must support NFS over RDMA and provide 400 GbE links to the edge. The design currently consists of leaf and spine switches, which carry all traffic in VXLAN tunnels. Each switch is a CX 9300-32D switch. What is one correction that you should make to the design?

Answer: B

Explanation:
NFS over RDMA/RoCE requires lossless Ethernet behavior with DCB features such as PFC/ETS and ECN. For CX 9300-based RoCE designs, ECN is supported in the underlay, not in the VXLAN overlay, so RDMA storage traffic should not be carried through VXLAN tunnels.


NEW QUESTION # 75
When proposing Aruba CX switches with Fabric Composer for a customer replacing a legacy Cisco Nexus environment, what is an important assumption to document regarding the migration?

Answer: C

Explanation:
Since NX-OS and AOS-CX have different APIs and CLI syntax, any existing automation tooling built against Nexus will not be directly portable and should be flagged as a migration assumption/risk. AOS-CX does support VXLAN, and Fabric Composer does not eliminate VLANs.


NEW QUESTION # 76
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. One of your junior colleagues has recommended deploying CX 8325-32C BF 6F 2AC Bundle switches for border leaf switches. What issue should you point out with this plan?

Answer: A

Explanation:
The hospital link has strict requirements for high-capacity, encrypted wire-speed connectivity, so the proposed border leaf choice must be validated against that requirement.


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: A

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.
