HPE Network Data Center Professional Architect Exam Sample Questions (Q20-Q25):

NEW QUESTION # 20
Refer to the exhibit.

You could make a change to the services that will save the customer money without affecting the level of support provided. What is that change?

A. Selecting SW + TechSupp
B. Selecting HW Onsite + SW + TechSupp FC 4h OS CDMR
C. Selecting hardware support only FC 4h OS HW

Answer: B

Explanation:
Use the combined chassis-level Foundational Care service so the switch keeps the same 4-hour onsite hardware, software, and technical support coverage without adding unnecessary duplicate services for components.

NEW QUESTION # 21
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?

A. It allows the customer and architect to validate key design assumptions (e.g., failover behavior, interoperability) in a controlled environment before committing to full rollout
B. It guarantees the design will have zero issues in production
C. It replaces the need for a design document
D. It is required by law for all network designs

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 # 22
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 network and the firewall. 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?

A. 2x 25 GbE routed only ports between border leaf switch 1 and the active firewall 2x 25 GbE routed only ports between border leaf switch 2 and the passive firewall.
B. One VSX LAG to each firewall consisting of 25 GbE links on the border leaf switches, two SVIs on each LAG.
C. One VSX LAG that includes a full mesh of 25 GbE links between the border leaf switches and firewall cluster, two SVIs on the LAG.
D. One 100 GbElink between border leaf switch 1 and the active firewall. One 100 GbE link between border leaf switch 2 and the passive firewall. Two subinterfaces on each link that act as ROPs.

Answer: B

Explanation:
For two VRFs and an active/standby firewall pair, each firewall should have redundant VSX LAG connectivity with separate VLAN/SVI transit per VRF.

NEW QUESTION # 23
Which two are valid reasons to recommend a routed underlay (Layer 3 to the leaf) in a VXLAN/EVPN fabric design? (Choose two.)

A. It eliminates the need for any overlay technology
B. It requires no IP addressing on the underlay
C. It provides deterministic, ECMP-based load balancing across all spine-leaf links
D. It guarantees zero oversubscription regardless of hardware
E. It removes dependency on spanning tree in the underlay

Answer: C,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 # 24
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.)

A. The acquired company's physical data cable plant at the new location will meet the technical requirements of the new solution.
B. The IP segments in the existing data centers will remain the same as the acquired company.
C. The acquired company's existing contract staff will be hired as full-time employees
D. The implementation project manager will be from the acquired company
E. The power at the acquired company's data center locations is sufficient for the proposed equipment.

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.
