HPE Network Data Center Professional Architect Exam Sample Questions (Q16-Q21):

NEW QUESTION # 16
What is the primary purpose of conducting a "current state assessment" before beginning a data center network design?

A. To generate a sales quote immediately
B. To finalize the bill of materials before requirements are gathered
C. To establish a documented baseline of existing infrastructure, traffic patterns, and pain points that informs design decisions
D. To replace the need for stakeholder interviews

Answer: C

Explanation:
A current state assessment creates a factual baseline (topology, traffic flows, capacity, known issues) that the new design must account for or improve upon. It is not a substitute for interviews, nor should it precede requirements gathering in the overall process, nor is it a sales tool.

NEW QUESTION # 17
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. Equipment data sheets
C. Completed RFP Responses
D. Support entitlement QR codes

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 # 18
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. Avoid discussing future growth with the customer to keep scope narrow
B. Use a flat, non-modular Layer 2 network to keep the initial design simple
C. Design only for the current row and redesign the fabric entirely at each expansion
D. Design a modular spine-leaf architecture that allows adding leaf switches and racks incrementally without redesigning the core

Answer: D

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 # 19
You are modernizing a customer's legacy three-tier architecture with an L3 spine and leaf topology. The CX switches in the topology will provide the overlay. The customer data center uses six VRFs. The customer has asked for service leaf switches to connect to two clustered firewalls, which route and filter traffic between the VRFs. How should the service leaf switches connect to the firewalls?

A. On two VSX LAGs, which are in the default VRF
B. On four ROPs (two per switch), each ROP being in the default VRF
C. On two VSX LAGs, each of which carries one VLAN per VRF
D. On four ROPs (two per switch), each ROP being attached to the six data center VRFs

Answer: C

Explanation:
Create one multi-chassis LAG to each firewall. Each LAG operates as a Layer 2 trunk carrying a separate transit VLAN for every VRF. HPE's validated border-leaf configuration uses two MC- LAGs-one to each firewall-with the external VRF VLANs permitted on both.

NEW QUESTION # 20
A customer has deployed CX 10000 switches. Fabric Composer, and Pensando Policy and Services Manager (PSM). The switches are discovered in PSM but no VRFs or networks are added. Now the customer wants to get started by applying micro-segmentation to one network.
The customer tells you that they plan to add a policy with rules for permitting desired traffic from endpoints in this network. They will apply it as an egress policy to the network. At this point they will not add any other networks to PSM or apply policies to them. What warning should you give the customer about this plan?

A. An ingress policy not egress policy, is the correct direction for controlling traffic from endpoints.
B. When you apply a policy to one network, it is recommended to add all the networks in its VRF to PSM.
C. The customer should apply the egress policy at both the VRF and network level to ensure that it works properly.
D. The customer must enable strict firewall mode before applying policies to ensure they take effect.

Answer: B

Explanation:
For CX 10000/PSM policy enforcement, networks in the same VRF should be consistently represented in PSM. Adding only one network can lead to incomplete policy context and unexpected segmentation behavior.
