What are two use cases for Fibre Channel Zoning in a vSphere environment? (Choose two.)

1. A. Increases the number of targets presented to an ESXi host.
2. B. Controls and isolates paths in a fabric.
3. C. Controls and isolates paths to an NFS share.
4. D. Can be used to separate different environments.

Correct Answer: BD
Zoning provides access control in the SAN topology. Zoning defines which HBAs can connect to which targets. When you configure a SAN by using zoning, the devices outside a zone are not visible to the devices inside the zone.

Refer to the Exhibit.

An administrator reviews the Health of a virtual machine, as shown in the Exhibit.
Based on the exhibit, which three metrics can be used to determine the virtual machine’s Workload characteristics? (Choose three.)

1. A. CPU
2. B. Memory
3. C. Network IO
4. D. Threads
5. E. vNUMA Stats

Correct Answer: ABC
The three most important metrics that are needed to be observed to ensure virtual machine health are CPU, memory and Network I/O because they are directly related to how the virtual machine will perform during peak load hours.

An administrator decides to change the root password for an ESXi 6.x host to comply with the company's security policies.
What are two ways that this can be accomplished? (Choose two.)

1. A. Use the Direct Console User Interface to change the password.
2. B. Use the passwd command in the ESXi Shell.
3. C. Use the password command in the ESXi Shell.
4. D. Use the vSphere client to update local users.

Correct Answer: AB
To prevent unauthorized access to the vCenter Server Appliance Direct Console User Interface, you can change the password of the root user.
The default root password for the vCenter Server Appliance is the password you enter during deployment of the virtual appliance.
