NEW QUESTION # 94
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?
Answer: C
Explanation:
The scenario gives 10/25GbE requirements, but the exact current and future port-speed mix helps validate the best ToR model.
NEW QUESTION # 95
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?
Answer: B
Explanation:
Border leaf switches are designed to bridge overlay VXLAN networks to traditional VLAN-based external networks (such as legacy WAN edge routers), avoiding the need to replace or upgrade those devices as a prerequisite.
NEW QUESTION # 96
Refer to the exhibit.
You could make a change to the services that will save the customer money without affecting the level of support provided. What is that change?
Answer: C
Explanation:
Use the combined chassis-level Foundational Care service so the switch keeps the same 4-hour onsite hardware, software, and technical support coverage without adding unnecessary duplicate services for components.
NEW QUESTION # 97
You are modernizing a customer's legacy three-tier architecture with an L3 spine and leaf topology. The CX switches in the topology will provide the overlay. The customer data center uses six VRFs. The customer has asked for service leaf switches to connect to two clustered firewalls, which route and filter traffic between the VRFs. How can you maximize the efficiency of the traffic flow between subnets in the same VRF?
Answer: C
Explanation:
For traffic between subnets in the same VRF, distributed L3 anycast gateways allow routing directly at the leaf switches, avoiding inefficient hairpinning through centralized firewalls. The firewalls should be used for routed/filtering traffic between VRFs.
NEW QUESTION # 98
Which two items are typically part of a "gap analysis" performed after the current state assessment? (Choose two.)
Answer: C,D
Explanation:
A gap analysis compares current-state capabilities against future requirements and highlights existing limitations/risks that the new design needs to address. Travel, marketing, and label colors are unrelated to gap analysis.
