HPE Network Data Center Professional Architect Exam Sample Questions (Q24-Q29):

NEW QUESTION # 24
You have successfully installed, configured, and migrated the customer to the new Aruba CX data center equipment. What documents are normally part of the post-installation deliverables?

A. Inventory
B. Support entitlement QR codes
C. Completed RFP Responses
D. Equipment data sheets

Answer: A

Explanation:
Post-installation deliverables normally include updated as-built documentation such as device inventory, configurations, topology, and implementation details. Data sheets and RFP responses are pre-sales/design documents.

NEW QUESTION # 25
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. Replace the CX 9300-32D switches with CX 9300S switches to ensure support for RoCEv1/v2
C. Redesign the solution to carry traffic without VXLAN to ensure support for DCB
D. Continue to use CX 9300-32D switches for the spine but use CX 9300S switches as leaf switches to optimize costs

Answer: C

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 # 26
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. Whenever possible, ramp up the new infrastructure in parallel and do transparent switching from old to new core switch.
B. Close the production site for at least 1 day to do a bing-bang approach
C. Create a Migration Plan which describes a phased approach, i.e. access layer first, distribution layer second, etc.
D. Replace one access switch at a time and patch the ports by using a patch plan.

Answer: A,D

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 # 27
Which statement is true about VSX design?

A. VSX peer keepalive can be implemented over a VSX LAG.
B. VSX Inter-Switch Link must be implemented using direct links between peers.
C. VSX Inter-Switch Link can implemented over indirect links.
D. VSX peer keepalive links only supports 40G and 100G ports.

Answer: B

Explanation:
The VSX ISL is the dedicated synchronization/data link between the two VSX peers and must be directly connected. The keepalive should use a separate path, often OOBM or routed connectivity.

NEW QUESTION # 28
What is the correct statement with regard to flow synchronization on the HPE Aruba Networking CX 10000 Distributed Services Modules (DSM) operating in VSX?

A. Flow state on the DSMs is not synchronized between the VSX members.
B. Flow state is synchronized between the matching DSMs between the VSX peers.
C. Flow state on DSM1 of a VSX member is synchronized to any DSM on the other VSX member.
D. Flow state on DSM1 of a VSX member is synchronized to DSM2 on the other VSX member.

Answer: B

Explanation:
In a CX 10000 VSX pair, firewall flows are synchronized across the logical VSX VTEPs, and DSM flow sync is done between matching DSMs, not randomly or cross-mapped between DSM1 and DSM2.
