HPE Network Data Center Professional Architect Exam Sample Questions (Q37-Q42):

NEW QUESTION # 37
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 # 38
You're presenting your solution to your customer. What's important to include in your presentation?

A. your experience with this kind of project
B. tangible and intangible returns for the customer
C. your rollback plan
D. The protocols that will be used to make your solution work.

Answer: B

Explanation:
A solution presentation should clearly show the customer's business value, including measurable benefits and less tangible gains such as improved reliability, agility, or operational efficiency.

NEW QUESTION # 39
Waratah Hospital, based in Australia, is planning to move many data center services to new facility. (The remaining legacy data center will not be part of this project.) Waratah Hospital hired an external consultant to assist with the new data center network design.
Based on the requirements for the data center network infrastructure, the external consultant has created a high-level design. The below summarizes the content of the design document.
Requirements and information:
- Six racks in the data center room (single row).
- Redundant Top of Rack leaf switches with back-to-front cooling in each rack, providing 10/25 Gbps connectivity to servers, storage, and other devices.
- Four 100 GbE uplinks per leaf switch.
- The customer requested to install all switch ports facing the back of the rack racks (hot aisle.)
- OOB management for servers, storage, and network has to be provided through an external switch with back-to-front cooling. This switch has to be included in the solution. One OOB switch provides connectivity for two racks.
- Core equipment for the OOBM network is being reused.
- Middle-of-row spine switches.
-The data center should connect to the hospital building with links that provide 400 Gbps.
- Internet access is provided through an existing firewall cluster with two firewalls, each firewall in one data room. The second firewall is operating in standby mode, VRRP is utilized on the firewalls for failover. The data center network should connect to these firewalls with links that total
100 Gbps.
- The external link is a dark fiber direct link based on single-mode fiber (OS2). The distance to the main hospital 1.5 KM. The links will terminate on two core switches in the hospital.
The customer also requires:
- 99.999% uptime for this life-critical environment.
- Planned and unplanned downtime has to be minimized.
- Software upgrades are only allowed once per year with close to zero downtime.
- All life-critical resources are accessed locally, and all resources exist within the hospital campus.
- Waratah Hospital requires a highly secure environment for the data center. Encrypted wire speed connectivity between the data room and the hospital is a must-have because the link between the buildings crosses a public road.
- Waratah Hospital has a mix of virtualized (vSphere) servers. Nutanix storage, bare metal servers, backup servers and other devices.
In the past, the hospital has had a security breach that resulted in data loss, network downtime, and identity theft.
Refer to the scenario. You have learned that the customer needs to extend two VRFs between the new data center facility and the hospital. To meet with the requirements of the scenario and general best practices, what should you recommend for connecting border leaf switches to the hospital core?

A. 8x 50Gbps links that are all routed only ports (ROPs). These ports establish two full meshes between two border leaf switches and two hospital core switches.
B. 4x 100 Gbps links that are routed only ports. Border leaf switch 1 has two ports that connect to hospital core switch 1. Border leaf switch 2 has two ports that connect to hospital core switch 2.
C. 8x 50Gbps links that establish two full meshes between two border leaf switches and two hospital core switches. The 4 links that connect to the hospital core 1 in one VSX LAG, and the other 4 links are in another VSX LAG.
D. 4x 100 Gbps links, establishing a full mesh between two border leaf switches and two hospital core switches. Each link should have two subinterfaces acting as routed only ports.

Answer: D

Explanation:
This provides 400Gbps total, full-mesh resiliency, and separate routed connectivity for the two VRFs.

NEW QUESTION # 40
Which two considerations should be included in a disaster recovery (DR) design for a data center network spanning two sites? (Choose two.)

A. Layer 2 extension or routed DR approach for workload mobility between sites
B. RPO (Recovery Point Objective) and RTO (Recovery Time Objective) targets defined by the business
C. The color scheme of the network diagrams
D. Ensuring only one site has any redundant hardware
E. The customer's preferred font for documentation

Answer: A,B

Explanation:
DR designs must be driven by business-defined RPO/RTO targets, and the network must support the chosen workload mobility method (stretched L2 via EVPN VXLAN, or routed/L3 failover).
Documentation aesthetics and asymmetric redundancy are not relevant DR design considerations.

NEW QUESTION # 41
You are proposing HPE Aruba Networking Central for a customer. Which customer requirement can only be fulfilled by AAS license, as opposed to an AAE license?

A. The customer has budget available to pay for a full 3-year license as part of the initial payment for the networking solution.
B. The customer is purchasing some licenses now and more licenses in a few months and would like the option to have the term end for all the licenses.
C. The customer requires a license that supports AI Insights for CX 8325 and CX 9300 switches.
D. The customer is just getting acquainted with HPE Aruba Networking Central and wants to start with a 1-year license.

Answer: B

Explanation:
AAS/aaS SKUs provide flexible consumption options such as license co-termination, which lets licenses purchased at different times align to a common end date.
