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) 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.
B) 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.
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.

2. You have designed an L3 spine and leaf topology for a customer's data center which is highly virtualized with VMware vSphere. This customer already uses HPE Aruba Networking mobility and switching solutions in the campus. You are recommending CX 8325 and CX 9300 switches and Fabric Composer The customer asks you to justify the cost of the Fabric Composer licenses.
What should you explain?

A) This solution's integration with ITSMs such as ServiceNow helps cu'tomers troubleshoot more quickly.
B) This solution's deep integration with vSphere saves IT time and el'minates costly errors with features like automatic VLAN provisioning.
C) This solution enables the customer to monitor the data center and campus solutions from the same cloud console, eliminating travel costs.
D) This solution uses agentic AI to run the network automatically, reducing IT operational costs.

3. You are finalizing a proposal for a data center network consisting of 14 CX 8325 switches, 6 CX
6300M switches, and Fabric Composer licenses for those switches. What is one assumption that you might include in the assumptions documentation?

A) The customer has an Internet connection over which switches' mgmt ports can receive access to the cloud-based management solution.
B) The customer has sufficient OPEX budget to pay for the Fabric Composer licenses
C) The customer has ESXi or KVM hosts that have sufficient resources to run Fabric Composer and can connect to the OOBM network.
D) The customer has attended or enrolled for training on using Fabric Composer.

4. 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) The customer must enable strict firewall mode before applying policies to ensure they take effect.
B) The customer should apply the egress policy at both the VRF and network level to ensure that it works properly.
C) When you apply a policy to one network, it is recommended to add all the networks in its VRF to PSM.
D) An ingress policy not egress policy, is the correct direction for controlling traffic from endpoints.

5. A customer's compliance team requires that PCI-scoped systems be logically isolated from the rest of the data center, with all inter-zone traffic inspected. Which design element addresses this requirement?

A) Increasing the MTU size on all switches
B) A single flat VLAN for all workloads
C) VRF segmentation combined with a firewall or service insertion point between VRFs
D) Disabling spanning tree throughout the fabric
