Waratah Hospital, located in Australia, plans to relocate many data-center services to a new facility. The remaining legacy data center is outside this project's scope. Waratah Hospital engaged an external consultant to help design the new data center network.
Based on the data center network-infrastructure requirements, the external consultant created a high-level design. The design document is summarized below.
Requirements and information:
Six racks in the data center room, arranged in a single row.
Redundant top-of-rack leaf switches with back-to-front cooling in every rack, delivering 10/25 Gbps connectivity for servers, storage, and other devices.
Four 100 GbE uplinks per leaf switch.
The customer requested that all switch ports face the rear of the racks (the hot aisle).
OOB management for servers, storage, and network devices must be provided through an external switch with back-to-front cooling. This switch must 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 must connect to the hospital building using links that provide 400 Gbps.
Internet access is supplied through an existing firewall cluster with two firewalls, with one firewall in each data room. The second firewall operates in standby mode, and VRRP is used on the firewalls for failover. The data center network must connect to these firewalls with links totaling 100 Gbps.
The external link is a direct dark-fiber link based on single-mode fiber (OS2). The distance to the main hospital is 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 must be minimized.
Software upgrades are permitted only once per year, with close to zero downtime.
All life-critical resources are accessed locally, and all resources are located within the hospital campus.
Waratah Hospital requires a highly secure data center environment. Encrypted wire-speed connectivity between the data room and the hospital is mandatory because the link between the buildings crosses a public road.
Waratah Hospital has a mixture of virtualized (vSphere) servers, Nutanix storage, bare-metal servers, backup servers, and other devices.
The hospital previously experienced a security breach that caused data loss, network downtime, and identity theft.
Which valid assumptions can be made for this scenario when preparing the network design documentation?
Choose two.

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

Refer to the exhibit.

You can change the services to save the customer money without affecting the level of support delivered.
What change should you make?

• A. Selecting SW + TechSupp
• B. Selecting hardware support only FC 4h OS HW
• C. Selecting HW Onsite + SW + TechSupp FC 4h OS CDMR

Identify the documentation resources that provide validated information to help the architect design the solution. Choose two.

• A. Configuration guides
• B. Competitive documentation
• C. Data sheets
• D. Product reviews (cnet, networkworld)
• E. LinkedIn

You are implementing a spine-and-leaf architecture using 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. You currently plan to use two 100-Gbps uplinks per leaf switch.
The customer now requires at least a 50% increase in uplink bandwidth per leaf switch. What is a valid modification to the plan?

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

You have been asked to help design an HPE Aruba Networking CX network solution that connects AI servers to file storage. The solution must support NFS over RDMA and deliver 400 GbE links to the edge. The current design uses leaf and spine switches that carry all traffic in VXLAN tunnels. Every switch is a CX
9300-32D switch.
What is one correction you should make to the design?

• A. Continue to use CX 9300-32D switches for the spine but use CX 9300S switches as leaf switches to optimize costs
• B. Eliminate the spine to establish a rail-only topology
• C. Redesign the solution to carry traffic without VXLAN to ensure support for DCB
• D. Replace the CX 9300-32D switches with CX 9300S switches to ensure support for RoCEv1/v2
