Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a client leaves a subnet, it should release the configuration received by the server using ____
A
DHCPOFFER
B
DHCPDISCONNECT
C
DHCPACK
D
DHCPRELEASE
Explanation: 

Detailed explanation-1: -If a server receives a DHCPREQUEST message, the server marks the address as leased. Servers that are not selected will return offered addresses to their available pool. The selected server sends the client an acknowledgment (DHCPACK), which contains additional configuration information.

Detailed explanation-2: -The DHCP server does not issue an acknowledgement of receipt of the client’s DHCP request because it keeps the IP address until the lease time is over. If a DHCP message is lost, they give-up its IP address.

Detailed explanation-3: -To release the DHCP assigned address, use the following CLI command: clear dhcp lease interface <ethernet interface> ip <ip-address>. In the example below, we will clear the 10.192. Confirm the release by returning to the DHCP server screen and viewing the allocated addresses again, as in Step 2 above. 26-Sept-2018
