HPE Network Data Center Professional Architect Sample Questions:

Question #1
During a design workshop, the customer states their applications are highly sensitive to latency and jitter, such as real-time market data feeds. What design change might you propose?

A. Add additional aggregation tiers to increase path diversity
B. Reduce the number of spine switches to simplify the topology
C. Implement a non-blocking, low-latency spine-leaf fabric with minimal oversubscription and hardware timestamping/PTP support if needed
D. Use store-and-forward switches exclusively to guarantee accuracy over speed

Question #2
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. The customer must enable strict firewall mode before applying policies to ensure they take effect.
C. When you apply a policy to one network, it is recommended to add all the networks in its VRF to PSM.
D. The customer should apply the egress policy at both the VRF and network level to ensure that it works properly.

Question #3
A customer wants each of their three data centers to be able to fail over workloads to either of the other two sites. Which network design approach best supports this "any-to-any" DR model?

A. A hub-and-spoke design with only one DR-capable site
B. Isolating each site so no inter-site traffic is possible
C. Static routes configured manually between each site pair
D. A distributed EVPN VXLAN fabric extended across all three sites using a DCI (Data Center Interconnect)

Question #4
A customer wants to know how their new EVPN VXLAN fabric will interoperate with their existing WAN edge routers, which only support traditional VLAN trunks. What is an appropriate design element to bridge this gap?

A. Extend VXLAN all the way to the WAN routers by upgrading their firmware
B. Use border leaf switches to perform VXLAN-to-VLAN translation (bridging) toward the WAN edge
C. Require the customer to replace all WAN routers before the project can begin
D. Disable the overlay entirely for WAN-facing traffic

Question #5
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. Does the customer want to adopt a single source-of-truth automation/orchestration approach (e.g., Fabric Composer) as part of the new design?
B. What brand of laptop does the network team use?
C. What is the customer's preferred web browser for the switch GUI?
D. How many cables are currently unused in the data center?
