HP HPE7-A12 : HPE Network Data Center Professional Architect Exam

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.
What are valid assumptions that can be made for this scenario when creating the network design documentation? (Choose two.)

• A. Sufficient cabling between data centers will be available.
• B. The customer s staff can implement the project.
• C. Hardware delivery will meet project timelines.
• D. Sufficient virtualization resources for the deployment of software will be available.
• E. The customer's budget for the project will be met.

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

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

Which factor should most influence the decision to use a two-tier (spine-leaf) versus a three-tier (spine-super spine-leaf) fabric design?

• A. The customer's preferred switch vendor logo
• B. The color of the network diagrams
• C. The number of employees in the customer's HR department
• D. The total scale of the fabric -- very large environments exceeding the port capacity of a two-tier spine may require a super-spine tier to interconnect multiple spine-leaf pods

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

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