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

You are delivering a spine and leaf architecture based on 18 CX 8360-48Y6C v2 leaf switches and two CX 8325-32C spine switches. The leaf switches support servers with 10 and 25 GbE ports. Currently you are planning to use two 100 Gbps uplinks per leaf switch. The customer returns with the requirement to increase the uplink bandwidth by at least 50% per leaf switch.
What is a valid change to the plan?

• A. Add a third CX 8325-32C switch and connect it to each leaf switch with a 100 GbE link
• B. Convert both uplinks on each leaf switch (and connected spine switches) to 200 GbE links
• C. Add another 100 GbE link to each leaf switch. One switch in each VSX pair connects to spine 1, and one switch connects to spine 2.
• D. Add another 100 GbE link between each leaf switch and both spine switches

Which of the following best describes the purpose of a "risk register" in a data center network design project?

• A. A list of the switches to be purchased
• B. A financial ledger of the project's profit margin
• C. A tracked list of identified risks, their likelihood/impact, and mitigation or contingency plans
• D. A record of every email exchanged with the customer

You delivered an L3 spine and leaf topology to a customer several years ago. The solution consisted of two CX 8325-32C switches at the spine and 20 CX 8325-48Y8C leaf switches. The leaf switches operate as 10 VSX pairs. The customer would now like to double the forwarding capacity of the topology. What should you recommend?

• A. Adding two more spine switches that connect to each leaf switches with 100 GbE links
• B. Upgrading the existing links to 200 GbE
• C. Adding one more spine switch that connects to each leaf switch with two 100 GbE links
• D. Add two more 100GbE links between each leaf switch and spine switch

What is the primary benefit of using EVPN as the control plane for a VXLAN overlay, compared to traditional flood-and-learn VXLAN?

• A. EVPN eliminates the need for a physical underlay
• B. EVPN uses BGP to proactively distribute MAC and IP reachability information, reducing unknown- unicast flooding and improving convergence
• C. EVPN only works with IPv6
• D. EVPN removes the need for VTEPs

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