Which of the following is displayed by the show ip dhcp snooping databasecommand? (Select the best answer.)

A.
the DHCP snooping configuration for a switch

B.
dynamic entries in the binding table

C.
the status of the binding table

D.
detailed DHCP snooping statistics

Explanation:
The show ip dhcp snooping database command displays the status of the binding table. When Dynamic Host
Configuration Protocol (DHCP) snooping is configured on a Cisco Catalyst switch, the switch tracks client
Media Access Control (MAC) addresses and their associated DHCP client hardware addresses in the DHCP
snooping binding database, which is also known as the binding table. If the switch receives DHCP packets that
do not match entries in the binding table, the switch drops the packets. The binding table can be stored locally
or it can be stored on a remote server. The show ip dhcp snooping databasecommand can be used to display
the status of the DHCP snooping binding table agent and statistics regarding the status of the binding table,
such as the Uniform Resource Locator (URL) where the binding table can be found and how many successful
writes have been committed to the table. For example, the following sample output indicates that the binding
table is stored in a file named bindingtable on the Trivial File Transfer Protocol (TFTP) server with an IP
address of 1.2.3.4:

The show ip dhcp snooping command displays general information regarding the DHCP snooping configuration
on a switch, such as the virtual LANs (VLANs) for which DHCP snooping is enabled and the trusted state of
each interface. For example, the following sample output indicates that DHCP snooping is enabled for VLANs
101, 201, and 301:

The show ip dhcp snooping binding command displays the dynamic entries in the binding table. You must use
the show ip source binding command to view both static and dynamic binding table entries. For example, the
following sample output from the show ip dhcp snooping binding command indicates that two DHCP clientsfrom VLAN 101 have entries in the binding table:

The show ip dhcp snooping statistics detail command displays detailed DHCP snooping statistics, which
include the number of packets dropped for each denial category, such as binding mismatches or exceeded rate
limits. For example, the following sample output from the show ip dhcp snooping statistics detail command
indicates that 2,130 packets were processed by DHCP snooping and 41 packets were dropped because of
binding mismatches:
