質問 # 62
A customer's data center uses structured cabling based on MMF O'5. The customer wants to upgrade the spine switches in their spine and leaf topology. A key goal of this upgrade is to eventually support 400GbE leaf-to-spine links. However, for a while, many of the leaf switches will continue to support 100GbE uplinks. What is a valid recommendation for the spine switches?
正解：B
解説：
With existing MMF OM5 structured cabling, 400G QSFP-DD MPO-16 optics are the valid migration choice for 400GbE spine links. The 4x100G DR option is for single-mode fiber, not MMF.

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.
Given the scenario, what environmental information should be gathered to complement the design? (Choose two.)
正解：A、B
解説：
Heat dissipation and power requirements are environmental details that still need to be validated for the physical deployment.

In this scenario, the customers servers are HPE Servers. For the iLO ports, you propose a 6300M switch for each rack. What is the best practice to connect these switches to the data center data plane?
正解：B
解説：
iLO/OOB management should remain on the out-of-band management network, separate from the production data plane.
質問 # 65
You are proposing an L3 spine and leaf topology to a customer. The solution consists of four CX
8325-32C switches at the spine and two CX 8325-48Y8C switches in each server rack. For this customer, you are using the leaf switches in a rack to provide the border leaf functionality. The customer's data center is growing and the customer asks you how many total server racks this solution can scale to support. What should you say?
正解：D
解説：
Each CX 8325-32C spine has 32 usable 100G ports. Each server rack has two leaf switches, and each spine needs one connection to each leaf, so each rack consumes 2 ports per spine. 32 ÷ 2
= 16 total racks.
質問 # 66
You are planning a pair of CX switches to act as ToR switches. The switches implement VSX as part of a data center L2 topology and connect to the core on VSX LAGs. To meet expansion requirements, you need to keep as many ports open as possible. What option should you recommend for VSX LAGs?
正解：D
解説：
VSX keepalives should use an independent path from the ISL. Using the OOBM management interface preserves front-panel data ports while still providing a separate keepalive path.
