질문 # 81
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 scenario. You are trying to decide between the CX 9300 and CX 8325 switches for the border leaf switches. What is a hard requirement for this customer that affects this decision?
정답：D
설명：
The scenario states that encrypted wire-speed connectivity is a must-have because the link crosses a public road.
질문 # 82
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?
정답：A
설명：
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.
질문 # 83
You have designed a spine and leaf topology, which includes 16 leaf switches and four spine switches. The customer has no existing overlay solution. You are helping the implementer work with the customer to obtain IP address blocks for the design. You plan to ask for these /24 subnets. One for an individual loopback interface for each switch. One for point-to-point connections between leaf and spine switches. What is one of the corrections you must make?
정답：B
설명：
In an EVPN-VXLAN spine-leaf design with VSX leaf pairs, you need individual loopbacks for switch identity/control-plane functions and an additional shared loopback per VSX pair for the common VTEP/anycast function.
질문 # 84
You are choosing switches for a new rack, which needs to support several types of traffic including HTTPS multicast streaming, and iSCSI traffic You are attempting to choose between CX 8360v2-32Y6C and CX 8325-48Y8C models both of which can meet the racks' port requirements. Which technical requirement should point you toward the 8325 model?
정답：C
설명：
CX 8325 supports multiple dedicated lossless buffer pools, which fits a design requiring separate buffer allocation for different iSCSI tiers. CX 8360 supports PFC, but with shared loSSLESs resources rather than the same isolated pool model.
질문 # 85
Which information should you attempt to discover during your first data center network design meetings with the customer? (Choose two.)
정답：A,E
설명：
Early design meetings should establish key project context and constraints, such as whether the deployment is greenfield or brownfield and the available project budget. Detailed switch sizing and training planning come later.
