Question 3

If a DHCP already has an IP address, it sends a ____ message to a DHCP server requesting local configuration information only.
A)DHCPInform
B)DHCPAck

Accepted Answer

When a device that already has an IP address needs local configuration information from a DHCP server, it sends a DHCPInform message to the server. This message does not request a new IP address, as the device already has one. Instead, it requests additional network configuration information such as DNS servers and gateway settings.

Question 12

A DHCP client sends a ____ message to a DHCP server to relinquish its IP address and end its lease.
A)DHCPInform
B)DHCPAck
C)DHCPDecline
D)DHCPRelease

Accepted Answer

When a DHCP client wants to relinquish its IP address and end its lease, it sends a DHCPRelease message to the DHCP server. This message tells the server that the client no longer needs the leased IP address and the server is free to reuse it. The other options are not relevant to this scenario. DHCPInform is used by a client to request information from the server without requesting an IP address. DHCPAck is the server's response to a client's DHCPRequest message confirming the assignment of an IP address. DHCPDecline is sent by a client to a server to decline an offered IP address.

Question 13

A DHCP client sends a ____ message to a DHCP server that declines an offered IP address.
A)DHCPNack
B)DHCPAck
C)DHCPDecline
D)DHCPRelease

Accepted Answer

When a DHCP client declines an offered IP address, it sends a DHCPDecline message to the DHCP server. DHCPNack is a message sent by the DHCP server when it cannot fulfill a DHCP client's request, DHCPAck is a message sent by the DHCP server when it offers an IP address to a DHCP client, and DHCPRelease is a message sent by the DHCP client when releasing its assigned IP address.
