HP HPE7-A12 Exam Syllabus Topics:

HPE Network Data Center Professional Architect Sample Questions:

1. You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN. The customer does not require VRF segmentation for any of the data center endpoint traffic. What should you recommend for the VRF in which to place the SVIs for server, VM and other endpoint VLANs?

A) Use any VRF name except default
B) Use whichever VRF the switch individual loopback interface is attached to
C) Use the default VRF
D) Use whichever VRF the switch VXLAN loopback interface is attached to

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

3. A customer wants to migrate from a traditional VLAN-based data center network to a VXLAN/EVPN fabric with minimal disruption. What is an appropriate first step in the design process?

A) Design a coexistence strategy using a VXLAN-to-VLAN gateway (border leaf) to bridge legacy and new segments during migration
B) Skip EVPN control plane design since VXLAN alone is sufficient
C) Immediately decommission the existing VLAN-based network
D) Require the customer to migrate all workloads to a public cloud instead

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. One of your junior colleagues has recommended deploying CX 8325-32C BF 6F 2AC Bundle switches for border leaf switches. What issue should you point out with this plan?

A) These switches do not meet all of the customer's requirements for the link to the hospital.
B) These switches cannot establish 4x 25 GbE links to comply with best practices for connecting to the firewalls.
C) These switches are using the wrong airflow for the customers environment.
D) These switches do not support sufficient power redundancy for the customer's requirements.

5. During requirements gathering, the customer's application owner states RTO must be under 60 seconds for a critical database cluster. Which network-level design decision most directly supports this requirement?

A) Increasing the ARP cache timeout to reduce protocol overhead
B) Using fast-converging protocols (e.g., BFD with routing protocols, sub-second VSX failover) and minimizing L2 dependency for that segment
C) Relying solely on manual failover procedures
D) Using default STP timers throughout the fabric
