HPE Network Data Center Professional Architect Exam Sample Questions (Q57-Q62):

NEW QUESTION # 57
A customer wants to migrate from a traditional VLAN-based data center network to a VXLAN/EVPN fabric with minimal disruption. What is an appropriate first step in the design process?

A. Design a coexistence strategy using a VXLAN-to-VLAN gateway (border leaf) to bridge legacy and new segments during migration
B. Require the customer to migrate all workloads to a public cloud instead
C. Immediately decommission the existing VLAN-based network
D. Skip EVPN control plane design since VXLAN alone is sufficient

Answer: A

Explanation:
Migrations should minimize disruption; a border leaf function bridges legacy VLAN-based segments into the new VXLAN/EVPN fabric so services can be migrated incrementally. EVPN is the standard control plane for VXLAN and should not be skipped, since it provides MAC/IP learning and reduces flood-and-learn behavior.

NEW QUESTION # 58
You have designed an L3 spine and leaf topology for a customer's data center which is highly virtualized with VMware vSphere. This customer already uses HPE Aruba Networking mobility and switching solutions in the campus. You are recommending CX 8325 and CX 9300 switches and Fabric Composer The customer asks you to justify the cost of the Fabric Composer licenses.
What should you explain?

A. This solution's deep integration with vSphere saves IT time and el'minates costly errors with features like automatic VLAN provisioning.
B. This solution enables the customer to monitor the data center and campus solutions from the same cloud console, eliminating travel costs.
C. This solution uses agentic AI to run the network automatically, reducing IT operational costs.
D. This solution's integration with ITSMs such as ServiceNow helps cu'tomers troubleshoot more quickly.

Answer: A

Explanation:
Fabric Composer provides VMware vSphere integration and automation for data center fabric operations, including simplifying/automating VLAN and network provisioning.

NEW QUESTION # 59
A customer's data center has 40 racks and is growing. The customer asks you to recommend a fabric topology that supports predictable latency and easy horizontal scaling. Which topology should you recommend?

A. Three-tier core-distribution-access
B. Spine-leaf (Clos) fabric
C. Full-mesh access layer
D. Ring topology

Answer: B

Explanation:
A spine-leaf (Clos) fabric provides consistent, predictable latency between any two leaf switches (every leaf is equidistant from every other leaf through the spine) and scales horizontally by adding spine or leaf switches without redesigning the fabric. Three-tier designs introduce variable latency and are harder to scale predictably; ring and full-mesh access designs don't fit modern DC scale requirements.

NEW QUESTION # 60
Which of the following is an appropriate deliverable to include in a High-Level Design (HLD) document, as opposed to a Low-Level Design (LLD)?

A. Switch configuration CLI commands
B. Exact port-by-port cabling diagram
C. Specific IP addressing for every VLAN
D. Conceptual topology diagram and overall architecture rationale

Answer: D

Explanation:
An HLD captures the conceptual architecture, topology, and design rationale at a strategic level.
Detailed cabling diagrams, IP addressing schemes, and CLI configurations belong in the LLD, which documents implementation-level detail.

NEW QUESTION # 61

A. Hardware and support, but not software
B. Hardware and software, but not support
