HP HPE7-A12 Exam Syllabus Topics:

HPE Network Data Center Professional Architect Sample Questions:

1. You are planning a CX-based data center network that applies east-west firewall policies, managed by AMD Pensando Policy and Services Manager (PSM). Which network should be used to communicate with PSM?

A) In the cloud with access to any overlay VRF to which policies will be applied
B) In the OOBM network
C) In the cloud with access to one VRF in which all managed switches have an interface
D) In the network underlay

2. 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 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.
B) 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.
C) 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.
D) 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.

Waratah Hospital requires a high availability deployment of Aruba Fabric Composer. How many nodes are supported with the high availability option?

A) high availability is not supported
B) two nodes
C) three nodes
D) four nodes

4. You have been called in to help design an HPE Aruba Networking CX network solution to connect AI servers to file storage. The solution must support NFS over RDMA and provide 400 GbE links to the edge. The design currently consists of leaf and spine switches, which carry all traffic in VXLAN tunnels. Each switch is a CX 9300-32D switch. What is one correction that you should make to the design?

A) Replace the CX 9300-32D switches with CX 9300S switches to ensure support for RoCEv1/v2
B) Redesign the solution to carry traffic without VXLAN to ensure support for DCB
C) Eliminate the spine to establish a rail-only topology
D) Continue to use CX 9300-32D switches for the spine but use CX 9300S switches as leaf switches to optimize costs

5. A customer currently has a data center network that uses CX switches and Pensando to implement east-west firewalling. The data center is currently highly virtualized with VMware.
However, the customer is considering migrating some workloads to HPE VMs running on HPE Morpheus VM Essentials (VME). What should you explain?

A) The customer will not be able to implement microsegmentation between the HPE VMs on the same subnet, but can implement segmentation between VMs on different subnets.
B) The customer should purchase the HPE Morpheus Enterprise license to enable support for PVLAN and the full firewall features, including microsegmentation.
C) The customer should use the VME DSS plug-in to utilize the full firewall features, including microsegmentation.
D) The customer will not be able to implement the east-west firewall policies for traffic originating from the HPE VMs, but can continue to use the1nnatingcies to secure other data center traffic.
