HPE Network Data Center Professional Architect Exam Sample Questions (Q41-Q46):

NEW QUESTION # 41
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 # 42
You delivered an L3 spine and leaf topology to a customer several years ago. The solution consisted of two CX 8325-32C switches at the spine and 20 CX 8325-48Y8C leaf switches. The leaf switches operate as 10 VSX pairs. The customer would now like to double the forwarding capacity of the topology. What should you recommend?

A. Adding one more spine switch that connects to each leaf switch with two 100 GbE links
B. Adding two more spine switches that connect to each leaf switches with 100 GbE links
C. Upgrading the existing links to 200 GbE
D. Add two more 100GbE links between each leaf switch and spine switch

Answer: B

Explanation:
The current design has 2 spine switches, with each leaf connecting to each spine. Adding 2 more spines doubles the number of ECMP spine paths and therefore doubles the leaf-to-spine forwarding capacity, while staying within CX 8325-32C port limits.

NEW QUESTION # 43
Which two considerations should be included in a disaster recovery (DR) design for a data center network spanning two sites? (Choose two.)

A. The color scheme of the network diagrams
B. Layer 2 extension or routed DR approach for workload mobility between sites
C. The customer's preferred font for documentation
D. Ensuring only one site has any redundant hardware
E. RPO (Recovery Point Objective) and RTO (Recovery Time Objective) targets defined by the business

Answer: B,E

Explanation:
DR designs must be driven by business-defined RPO/RTO targets, and the network must support the chosen workload mobility method (stretched L2 via EVPN VXLAN, or routed/L3 failover).
Documentation aesthetics and asymmetric redundancy are not relevant DR design considerations.

NEW QUESTION # 44
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?

A. Continue to use CX 9300-32D switches for the spine but use CX 9300S switches as leaf switches to optimize costs
B. Replace the CX 9300-32D switches with CX 9300S switches to ensure support for RoCEv1/v2
C. Eliminate the spine to establish a rail-only topology
D. Redesign the solution to carry traffic without VXLAN to ensure support for DCB

Answer: D

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 # 45
Identify the documentation resources for finding validated information that assists the architect in designing the solution (Choose two.)

A. Competitive documentation
B. Product reviews (cnet, networkworld)
C. Data sheets
D. Configuration guides
E. LinkedIn

Answer: C,D
