HPE Network Data Center Professional Architect Exam Sample Questions (Q78-Q83):

NEW QUESTION # 78
Which two elements should be captured in the "success criteria" section of a data center network design proposal? (Choose two.)

A. The architect's personal preference for switch brand
B. Specific acceptance tests that validate the design meets stated requirements
C. The number of vacation days taken by the project team
D. Measurable performance targets (e.g., latency, uptime SLA) that define project success
E. The customer's stock price at contract signing

Answer: B,D

Explanation:
Success criteria should be measurable and testable -- such as defined performance/SLA targets and specific acceptance tests tied to the requirements -- so both the customer and architect can objectively confirm the design meets its goals. Personal preferences and unrelated business metrics don't belong here.

NEW QUESTION # 79
Refer to the exhibit.

You are designing a data center network. This customer requests that you connect the data center to campus core switches. The customer uses VLANs for segmentation, but not VRFs.
What is the recommended design for the links between the data center core switches and the campus core switches?

A. Link 1 and Link 3 should be one VSX LAG. Link 2 and Link 4 should be another VSX LAG.
B. Link 1 and Link 2 should be one VSX LAG. Link 3 and Link 4 should be another VSX LAG.
C. Each link should be a routed-only port (ROP) in a /31 subnet.
D. All links should be in the same VSX LAG.

Answer: C

Explanation:
The recommended campus-to-data-center core connection is Layer 3 routed links. Since the customer does not use VRFs, each physical link can be a simple point-to-point routed port using a /31 subnet.

NEW QUESTION # 80
A customer asks whether they should adopt a routed (Layer 3) access design or a bridged (Layer
2) access design for their new data center fabric. Which factor most strongly favors a routed access design?

A. The customer has no requirement for scalability
B. The customer wants to minimize the fault domain size and avoid spanning-tree dependency, and applications don't require L2 adjacency beyond the rack
C. The customer has many legacy applications requiring Layer 2 adjacency across racks
D. The customer wants to run VMware vMotion across the entire data center without any L3 boundary

Answer: B

Explanation:
A routed access design minimizes Layer 2 fault domains and removes dependency on spanning tree, which is ideal when applications don't require broad L2 adjacency. Legacy L2-dependent apps or unrestricted vMotion mobility across the entire DC would instead favor extending L2 (e.g., via VXLAN) further into the fabric.

NEW QUESTION # 81
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 is required by law for all network designs
B. It guarantees the design will have zero issues in production
C. It replaces the need for a design document
D. 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

Answer: D

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 # 82
A customer's security team requires micro-segmentation down to the individual workload level within the data center. Which technology combination best satisfies this requirement in an Aruba CX + VMware environment?

A. NSX distributed firewall for workload-level policy, integrated with the underlying VXLAN/EVPN fabric for transport
B. Disabling east-west traffic entirely
C. Physical firewalls between every server pair
D. VLANs alone, with no additional overlay

Answer: A

Explanation:
NSX's distributed firewall enforces security policy at the vNIC/workload level regardless of physical topology, while the CX VXLAN/EVPN fabric provides the underlying transport. VLANs alone can't achieve workload-level granularity, physical firewalls per server pair are impractical, and disabling east-west traffic breaks application functionality.
