A. Software and support, but not hardware
B. Hardware and software, but not support
C. Hardware and support, but not software
D. Hardware software, and support

Question 2

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?

A. The need to minimize downtime during software upgrades
B. The bandwidth requirements on the links to the hospital
C. Hardware encryption on the links to the hospital
D. The mixed speed requirements to connect to both the hospital and the internet firewall

Question 3

You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN with a distributed gateway model. You are helping implementers to assemble a list of required loopback interface IDs and IP blocks. What information do you need from the customer to complete this list?

A. Whether the customer prefers OSPF or BGP as a routing protocol
B. For each overlay VRF whether the customer requires L2 multicast forwarding
C. For each overlay VRF, whether it will have DHCP servers to which relay is required
D. Whether the customer prefers a single-AS or dual-AS design for the VXLAN control plane

Question 4

You are planning a CX-based data center network that applies east-west firewall policies, managed by AMD Pensando Policy and Services Manager (PSM). Which network should be used to communicate with PSM?

A. In the network underlay
B. In the cloud with access to any overlay VRF to which policies will be applied
C. In the cloud with access to one VRF in which all managed switches have an interface
D. In the OOBM network

Question 5

A customer wants each of their three data centers to be able to fail over workloads to either of the other two sites. Which network design approach best supports this "any-to-any" DR model?

A. Static routes configured manually between each site pair
B. A hub-and-spoke design with only one DR-capable site
C. A distributed EVPN VXLAN fabric extended across all three sites using a DCI (Data Center Interconnect)
D. Isolating each site so no inter-site traffic is possible
