HPE Network Data Center Professional Architect Exam Sample Questions (Q76-Q81):

NEW QUESTION # 76
You are designing a network upgrade for a data center that is virtualized with VMware. The customer already uses NSX. You are handling the CX switch design, while the customer is handling the NSX design. What is one question to discuss for the logical design?

A. Whether the customer has a particular scheme they prefer for mapping VLANs to VNIs.
B. What routing is required between subnets inside and outside the overlay.
C. Into how many VRFs would the customer needs to segment the overlay networks.
D. How to correlate isolated VLAN IDs with primary VLAN IDs and whether to permit any traffic between isolated VLAN endpoints.

Answer: B

Explanation:
With NSX, the customer owns the overlay design, but the CX network design must account for how overlay networks connect to external/physical networks, including routing boundaries and route exchange.

NEW QUESTION # 77
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 is required by law for all network designs
C. It replaces the need for a design document
D. It guarantees the design will have zero issues in production

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 # 78
A customer's data center is expanding from one row to five rows over the next two years. What design principle should guide the initial fabric design to support this growth?

A. Design only for the current row and redesign the fabric entirely at each expansion
B. Design a modular spine-leaf architecture that allows adding leaf switches and racks incrementally without redesigning the core
C. Use a flat, non-modular Layer 2 network to keep the initial design simple
D. Avoid discussing future growth with the customer to keep scope narrow

Answer: B

Explanation:
A modular spine-leaf design allows incremental scale-out (adding leaves/racks) without re- architecting the fabric, which is essential when the customer has known growth plans. Designing only for the current state, or ignoring growth plans, risks a costly redesign later.

NEW QUESTION # 79
You are proposing an L3 spine and leaf topology to a customer. The solution consists of four CX
8325-32C switches at the spine and two CX 8325-48Y8C switches in each server rack. For this customer, you are using the leaf switches in a rack to provide the border leaf functionality. The customer's data center is growing and the customer asks you how many total server racks this solution can scale to support. What should you say?

A. 0
B. 1
C. 2
D. 3

Answer: B

Explanation:
Each CX 8325-32C spine has 32 usable 100G ports. Each server rack has two leaf switches, and each spine needs one connection to each leaf, so each rack consumes 2 ports per spine. 32 ÷ 2
= 16 total racks.

NEW QUESTION # 80
You are proposing HPE Aruba Networking Central for a customer. Which customer requirement can only be fulfilled by AAS license, as opposed to an AAE license?

A. The customer is just getting acquainted with HPE Aruba Networking Central and wants to start with a 1-year license.
B. The customer requires a license that supports AI Insights for CX 8325 and CX 9300 switches.
C. The customer is purchasing some licenses now and more licenses in a few months and would like the option to have the term end for all the licenses.
D. The customer has budget available to pay for a full 3-year license as part of the initial payment for the networking solution.

Answer: C

Explanation:
AAS/aaS SKUs provide flexible consumption options such as license co-termination, which lets licenses purchased at different times align to a common end date.
