HPE Network Data Center Professional Architect Exam Sample Questions (Q87-Q92):

NEW QUESTION # 87
You have delivered a CX 10000-based data center network to a customer. The customer wants to ensure a smooth transition to the new network before starting to implement the security capabilities. What should you recommend for the initial deployment?

A. Making sure that strict firewall bypass is enabled for ARP broadcasts
B. Making sure that all networks have been added to PSM with an egress policy that has no rules
C. Making sure that all VRFs have been added to PSM with an ingress policy that has no rules
D. Making sure that strict firewall mode is disabled

Answer: D

Explanation:
For an initial CX 10000 deployment, disabling strict firewall mode allows traffic to pass while the customer validates network connectivity before gradually implementing segmentation/security policies.

NEW QUESTION # 88
During discovery, you learn the customer's current data center has no automation and all changes are made via CLI on individual switches. What follow-up Qis most important for scoping the design?

A. What brand of laptop does the network team use?
B. What is the customer's preferred web browser for the switch GUI?
C. How many cables are currently unused in the data center?
D. Does the customer want to adopt a single source-of-truth automation/orchestration approach (e.g., Fabric Composer) as part of the new design?

Answer: D

Explanation:
Understanding whether the customer wants to move toward automated, intent-based fabric management directly affects switch model selection, licensing, and overall architecture. The other options are irrelevant to design scope.

NEW QUESTION # 89
The customer operates a 24/7 production facility and is concerned that the migration will disrupt the production line. What are two ways to minimize or eliminate this disruption? (Choose two.)

A. Replace one access switch at a time and patch the ports by using a patch plan.
B. Create a Migration Plan which describes a phased approach, i.e. access layer first, distribution layer second, etc.
C. Whenever possible, ramp up the new infrastructure in parallel and do transparent switching from old to new core switch.
D. Close the production site for at least 1 day to do a bing-bang approach

Answer: A,C

Explanation:
To minimize disruption in a 24/7 environment, build the new infrastructure in parallel where possible and migrate gradually. Replacing one access switch at a time with a detailed patch plan limits the impact to small, controlled sections.

NEW QUESTION # 90
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 requires a license that supports AI Insights for CX 8325 and CX 9300 switches.
B. The customer is just getting acquainted with HPE Aruba Networking Central and wants to start with a 1-year license.
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.

NEW QUESTION # 91
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. Eliminate the spine to establish a rail-only topology
B. Redesign the solution to carry traffic without VXLAN to ensure support for DCB
C. Continue to use CX 9300-32D switches for the spine but use CX 9300S switches as leaf switches to optimize costs
D. Replace the CX 9300-32D switches with CX 9300S switches to ensure support for RoCEv1/v2

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.
