After installation of a host in your test environment, you need to move it to production. The only major change that needs to be made is that the hostname of the
server needs to change.

What are two ways that an administrator can change the host name without editing configuration files on the host directly? (Choose two.)

A.
Login to the Direct Console User Interface and change it from here.

B.
Edit the Default TCP/IP Configuration from the vSphere Web Client.

C.
Use the Ruby vSphere Client to send a script to the ESXi host that updates the hostname.

D.
Update the information in DNS and the ESXi host will automatically update with these changes.

Explanation:
To change the host name without editing configuration files on the host, first, login to the direct console user interface and change the host name. Now edit the
default TCP/IP configuration from the vSphere client.
