Which command should she use?

Sahan wants to clear TCP/IP network information from her Windows NT workstation. Which
command should she use?

A.
Ipconfig /release

B.
Ipconfig /renew

C.
Ipconfig /clear

D.
Ipconfig /reset

Explanation:
The /release parameter will release the current IP address and cancel the lease. This command
can only be issued if the IP address and configuration was initially provided via a DHCP server.
Incorrect Answers:
B: The /renew is used to renew the current lease of the IP address. The /renew causes interaction
with the DHCP server to extend the current lease. It does not clear the information, the information
will remain.
C: /clear and /reset are not valid parameters of the ipconfig command. If they are used, they will

cause an error. Actually, since they are invalid, the ipconfig command will display the help screen
to show you what is valid, as well as the correct usage.
D: /clear and /reset are not valid parameters of the ipconfig command. If they are used, they will
cause an error. Actually, since they are invalid, the ipconfig command will display the help screen
to show you what is valid, as well as the correct usage.
