HPE Network Data Center Professional Architect Sample Questions:

1. 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) 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.
C) 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.
D) 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.

2. When proposing Aruba CX switches with Fabric Composer for a customer replacing a legacy Cisco Nexus environment, what is an important assumption to document regarding the migration?

A) The customer's existing Nexus switches will remain as the primary management plane
B) Existing automation scripts written for NX-OS APIs will need to be rewritten or replaced for the new platform
C) Fabric Composer requires the customer to eliminate all VLANs
D) VXLAN is not supported on Aruba CX switches

3. Your customer wants to host endpoints on the Border Leaf switches. Is this a supported topology?

A) Yes, configuring VLANs and SVIs on a Border is a supported way to operate.
B) No, as a Border Leaf is a pure Layer 3 device and has to remain like that.
C) No, as a Border Leaf only supports Loopback addresses.
D) Yes, using Routed-only ports.

4. Which information should you attempt to discover during your first data center network design meetings with the customer? (Choose two.)

A) What are the team's training needs for the project?
B) What's the budget allocated to this project?
C) What are the bandwidth requirements for the spine switches?
D) What are the data center's addresses?
E) Is it a greenfield or brownfield deployment?

5. Refer to the exhibit.

You are designing a data center network. This customer requests that you connect the data center core their firewalls. The customer uses six VRFs for segmentation, and the firewalls are responsible for handling traffic in all of the VRFs.
What is the recommended design for the links between the data center core switches and the firewalls?

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