HPE Network Data Center Professional Architect Exam Sample Questions (Q104-Q109):

NEW QUESTION # 104
You are brought in to a customer with 1,115 employees to update the network and the previous network manager has left the company. What are methods to validate the current network state when the available network documentation is not up-to-date? (Choose two.)

A. Documenting existing network configuration and topology is not required. Previous iterations of network designs are considered obsolete and the best practice is that new designs are 'clean- sheet' designs.
B. Interview random company staff to gather the 'tribal knowledge' of how the network functions during normal operations and degraded states.
C. Begin searching through file shares for old documentation and compare the files and drawings to each other.
D. Physically examine the network devices and trace the cables from device to device documenting the connections and cabling type.
E. Use neighbor discovery protocols to learn neighbor relationships, document the connections and build a topology from the learned information.

Answer: D,E

Explanation:
When documentation is outdated, the current state should be validated by directly inspecting physical cabling/devices and by using neighbor discovery protocols such as LLDP/CDP to identify real device relationships and build an accurate topology.

NEW QUESTION # 105
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 guarantees the design will have zero issues in production
C. It replaces the need for a design document
D. It is required by law for all network designs

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 # 106
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 DSM1 of a VSX member is synchronized to any DSM on the other VSX member.
B. Flow state on DSM1 of a VSX member is synchronized to DSM2 on the other VSX member.
C. Flow state on the DSMs is not synchronized between the VSX members.
D. Flow state is synchronized between the matching DSMs between the VSX peers.

Answer: D

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.

NEW QUESTION # 107
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. Skip EVPN control plane design since VXLAN alone is sufficient
B. Immediately decommission the existing VLAN-based network
C. Require the customer to migrate all workloads to a public cloud instead
D. Design a coexistence strategy using a VXLAN-to-VLAN gateway (border leaf) to bridge legacy and new segments during migration

Answer: D

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 # 108
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. Ring topology
B. Spine-leaf (Clos) fabric
C. Three-tier core-distribution-access
D. Full-mesh access layer

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.
