Refer to the exhibit. Router RTA has been configured as a DHCP server. The two debug
commands will generate output on RTA when Host A requests an IP address. Which set of
DHCPD debug messages is in the correct sequence?
A.
DHCPD: Sending DHCPOFFER to client
DHCPD: DHCPDISCOVER received from client
DHCPD: DHCPREQUEST received from client
DHCPD: Sending DHCPACK to client
B.
DHCPD: DHCPDISCOVER received from client
DHCPD: DHCPREQUEST received from client
DHCPD: Sending DHCPOFFER to client
DHCPD: Sending DHCPACK to client
C.
DHCPD: DHCPDISCOVER received from client
DHCPD: Sending DHCPOFFER to client
DHCPD: DHCPREQUEST received from client
DHCPD: Sending DHCPACK to client
D.
DHCPD: DHCPREQUEST received from client
DHCPD: Sending DHCPOFFER to client
DHCPD: DHCPDISCOVER received from client
DHCPD: Sending DHCPACK to client
E.
DHCPD: Sending DHCPACK to client
DHCPD: DHCPDISCOVER received from client
DHCPD: Sending DHCPOFFER to client
DHCPD: DHCPREQUEST received from client
F.
DHCPD: DHCPDISCOVER received from client
DHCPD: Sending DHCPACK to client
DHCPD: Sending DHCPOFFER to client
DHCPD: DHCPREQUEST received from client
Explanation:
The following example shows a combination of DHCP server events and decoded receptions
and transmissions:
Router# debug ip dhcp server events
Router# debug ip dhcp server packets
DHCPD:DHCPDISCOVER received from client 0b07.1134.a029 through relay 10.1.0.253.
DHCPD:assigned IP address 10.1.0.3 to client 0b07.1134.a029.
DHCPD:Sending DHCPOFFER to client 0b07.1134.a029 (10.1.0.3).
DHCPD:unicasting BOOTREPLY for client 0b07.1134.a029 to relay 10.1.0.253.
DHCPD:DHCPREQUEST received from client 0b07.1134.a029.
DHCPD:Sending DHCPACK to client 0b07.1134.a029 (10.1.0.3).
DHCPD:unicasting BOOTREPLY for client 0b07.1134.a029 to relay 10.1.0.253.
DHCPD:checking for expired leases.
Note that for this question, the correct order of events are highlighted above.http://www.cisco.com/en/US/docs/ios/debug/command/reference/db_h1.html#wp1020307
