HP HPE7-A12 Exam Syllabus Topics:

HPE Network Data Center Professional Architect Sample Questions:

1. You have designed a two-tier L2 data center network for a customer. When you are presenting the solution, the customer indicates that they have a mission-critical multicast application with sources and receivers in the data center. Which CX feature, beyond features provided by the PIM-SM standard, should you explain to emphasize the value of your solution?

A) Fast switchover from the RP tree to the shortest path tree
B) Bootstrap router (BSR) support, which makes the solution more automated and resistant to link failures
C) PIM-SM active-active with VSX which enables near instant failover for multicast streams if one core switch fails
D) VSX active forwarding, which enables multiple switches to act as PIM-SM active designated routers at the same time

2. Drag and Drop Question
Match the switch family with the capability.

3. To prepare for a data center network implementation, you have asked a customer for a list of VLANs to support. The customers list for several VMware ESXi hosts includes 4095. What follow up question should you ask?

A) What VLAN tags do the VMs connected to the 4095 port group use?
B) Is VLAN 4095 associated with the same subnet on all of those hosts?
C) Because this VLAN ID is reserved for the system on CX switches, is the customer open to changing that VLAN ID?
D) Is the customer using NSX to support this non-standard VLAN?

4. 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) 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) 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.

5. Which two factors should be part of a data center network's high availability (HA) design?
(Choose two.)

A) Redundant power and diverse uplinks between tiers
B) VSX (Virtual Switching Extension) between top-of-rack switch pairs
C) Selecting a single top-of-rack switch per rack with no backup
D) Disabling LACP to simplify configuration
E) Placing all spine switches in a single power zone
