Question 1 of 70

You are brought in to a customer with 1,115 employees to update the network and the previous network manager has left the company.
What are methods to validate the current network state when the available network documentation is not up-to-date? (Choose two.)

Documenting existing network configuration and topology is not required. Previous iterations of network designs are considered obsolete and the best practice is that new designs are 'clean-sheet' designs.

Begin searching through file shares for old documentation and compare the files and drawings to each other.

Physically examine the network devices and trace the cables from device to device documenting the connections and cabling type.

Use neighbor discovery protocols to learn neighbor relationships, document the connections and build a topology from the learned information.

Interview random company staff to gather the 'tribal knowledge' of how the network functions during normal operations and degraded states.

Question 2 of 70

To prepare for a data center network implementation, you have asked a customer for a list of VLANs to support. The customers list for several VMware ESXi hosts includes 4095.
What follow up question should you ask?

Is VLAN 4095 associated with the same subnet on all of those hosts?

What VLAN tags do the VMs connected to the 4095 port group use?

Is the customer using NSX to support this non-standard VLAN?

Because this VLAN ID is reserved for the system on CX switches, is the customer open to changing that VLAN ID?

Question 3 of 70

Which information should you attempt to discover during your first data center network design meetings with the customer? (Choose two.)

What are the data center’s addresses?

Is it a greenfield or brownfield deployment?

What are the team's training needs for the project?

What are the bandwidth requirements for the spine switches?

What’s the budget allocated to this project?

Question 4 of 70

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?

How the rack and switches installed in it are oriented toward hot and cold aisles.

Whether the customer requires the flexibility to extend VM networks across a routed underlay.

Precisely how many ports use 10 GbE versus 25 GbE and whether that mix might change.

Whether the customer has a preference for AOC versus DAC cables.

Given the scenario, what environmental information should be gathered to complement the design? (Choose two.)

heat dissipation requirements

connectivity requirements

power requirements

switch placement requirements
