HPE Network Data Center Professional Architect Exam Sample Questions (Q17-Q22):

NEW QUESTION # 17
You are designing a CX data center network for a customer who has indicated that they must integrate the switches in their automation workflows. Which capability enables your customer to fulfill their objectives?

A. gRPC
B. NETCONF
C. REST API with JSON
D. XML API

Answer: C

Explanation:
Aruba CX switches support automation through a REST API using JSON, which enables integration with external automation/orchestration workflows.

NEW QUESTION # 18
What is the best practice for using VSX at the Core of a two-tier design?

A. You should implement VSX at the core when the access layer operates at layer 2 only.
B. You should implement VSX at the core when the access is layer 3 only with OSPF routed traffic forwarding between core and access.
C. You should implement VSX at the core when the access switches implement EVPN VXLAN.
D. You should never implement VSX at the core of a two-tier design.

Answer: A

Explanation:
In a two-tier L2 access design, VSX at the core provides redundant active-active connectivity and default gateway resiliency for access switches. For L3-only or EVPN-VXLAN access designs, routed spine/core behavior is preferred instead.

NEW QUESTION # 19
You are proposing an L3 spine and leaf topology to a customer. The solution consists of four CX
8325-32C switches at the spine and two CX 8325-48Y8C switches in each server rack. For this customer, you are using the leaf switches in a rack to provide the border leaf functionality. The customer's data center is growing and the customer asks you how many total server racks this solution can scale to support. What should you say?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
Each CX 8325-32C spine has 32 usable 100G ports. Each server rack has two leaf switches, and each spine needs one connection to each leaf, so each rack consumes 2 ports per spine. 32 ÷ 2
= 16 total racks.

NEW QUESTION # 20
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 four ROPs (two per switch), each ROP being in the default VRF
B. On two VSX LAGs, which are 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 # 21
Refer to the exhibit.

You are designing a data center network. This customer requests that you connect the data center to campus core switches. The customer uses VLANs for segmentation, but not VRFs.
What is the recommended design for the links between the data center core switches and the campus core switches?

A. All links should be in the same VSX LAG.
B. Link 1 and Link 3 should be one VSX LAG. Link 2 and Link 4 should be another VSX LAG.
C. Link 1 and Link 2 should be one VSX LAG. Link 3 and Link 4 should be another VSX LAG.
D. Each link should be a routed-only port (ROP) in a /31 subnet.

Answer: D

Explanation:
The recommended campus-to-data-center core connection is Layer 3 routed links. Since the customer does not use VRFs, each physical link can be a simple point-to-point routed port using a /31 subnet.
