HP HPE7-A12 Exam Syllabus Topics:

HPE Network Data Center Professional Architect Sample Questions:

Question #1
A customer wants each of their three data centers to be able to fail over workloads to either of the other two sites. Which network design approach best supports this "any-to-any" DR model?

A. Isolating each site so no inter-site traffic is possible
B. A hub-and-spoke design with only one DR-capable site
C. A distributed EVPN VXLAN fabric extended across all three sites using a DCI (Data Center Interconnect)
D. Static routes configured manually between each site pair

Question #2
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. VSX active forwarding, which enables multiple switches to act as PIM-SM active designated routers at the same time
C. Bootstrap router (BSR) support, which makes the solution more automated and resistant to link failures
D. PIM-SM active-active with VSX which enables near instant failover for multicast streams if one core switch fails

Question #3
You have designed a spine and leaf topology, which includes 16 leaf switches and four spine switches. The customer has no existing overlay solution. You are helping the implementer work with the customer to obtain IP address blocks for the design. You plan to ask for these /24 subnets. One for an individual loopback interface for each switch. One for point-to-point connections between leaf and spine switches. What is one of the corrections you must make?

A. Ask for another subnet for point-to-point links in the overlay VRF
B. Ask for another subnet for loopback IP addresses shared by the two members of each VSX pair
C. Change the /24 subnet request for the point-to-point links to a /23 subnet
D. Change the /24 subnet request for the individual loopback addresses to a /25 subnet

Question #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.
Given the scenario, what environmental information should be gathered to complement the design? (Choose two.)

A. connectivity requirements
B. switch placement requirements
C. heat dissipation requirements
D. power requirements

Question #5
You have successfully installed, configured, and migrated the customer to the new Aruba CX data center equipment. What documents are normally part of the post-installation deliverables?

A. Equipment data sheets
B. Inventory
C. Support entitlement QR codes
D. Completed RFP Responses
