HP HPE7-A12 Exam : 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.
Refer to the rack requirements in the scenario. Which additional information can help you choose between CX 8325-48Y8C and CX 8360-48Y6C models?

• A. Precisely how many ports use 10 GbE versus 25 GbE and whether that mix might change.
• B. How the rack and switches installed in it are oriented toward hot and cold aisles.
• C. Whether the customer requires the flexibility to extend VM networks across a routed underlay.
• D. Whether the customer has a preference for AOC versus DAC cables.

Your long-time customer has just acquired a company with 3,500 employees and they are planning on bringing the new data center sites up to their standards. They have asked for a bill of materials given only locations and port counts at the data center sites. What are valid assumptions that should be documented in the proposal? (Choose two.)

• A. The implementation project manager will be from the acquired company
• B. The acquired company's physical data cable plant at the new location will meet the technical requirements of the new solution.
• C. The power at the acquired company's data center locations is sufficient for the proposed equipment.
• D. The acquired company's existing contract staff will be hired as full-time employees
• E. The IP segments in the existing data centers will remain the same as the acquired company.

You are designing an L3 spine and leaf architecture for a customer based on CX 10000 Series switches as leaf switches. The customer has added a requirEMENT that the leaf switches also support servers' iSCSI adapters. You have verified your design also meETS The customer's needs for lossless iSCSI. The customer asks for advice on ensuring that THE East-west firewall permits the iSCSI traffic. What should you explain?

• A. The customer should place the iSCSI adapters in a PVLAN primary VLAN to ensure trafFIC Is permitted.
• B. CX 10000 switches do not implement east-west firewall policies on traffic in a no-drop PFC queue.
• C. Fabric Composer supports VM tag-based Endpoint Groups (EPGs) which will make it easy for the customer to select the iSCSI traffic and permit it.
• D. The custOMER should place the iSCSI adapters in a PVLAN isolated VLAN to ensure traFFIC is forwarded without disruption from VM traffic.

A customer wants to know how their new EVPN VXLAN fabric will interoperate with their existing WAN edge routers, which only support traditional VLAN trunks. What is an appropriate design element to bridge this gap?

• A. Require the customer to replace all WAN routers before the project can begin
• B. Use border leaf switches to perform VXLAN-to-VLAN translation (bridging) toward the WAN edge
• C. Disable the overlay entirely for WAN-facing traffic
• D. Extend VXLAN all the way to the WAN routers by upgrading their firmware

When creating an endpoint group in Aruba Fabric Composer, which option do you select in the endpoints section if you want to protect the hypervisor?

• A. VNIC
• B. VM Kernel Adapter
• C. VM Tag
• D. VM Name
