Which of the following does the auto assign command configure a router to do? (Select the best answer.)

A.
automatically assign an ephone to an IP phone

B.
automatically assign an ephonedn to an ephone

C.
automatically assign an IP address to an IP phone

D.
automatically assign an IP phone to a hunt group

Explanation:
The auto assign command configures a router to automatically assign an ephonedn to an ephone. When an IP
phone registers with a router that is configured with the auto assigncommand, the router will associate button 1
on the IP phone’s ephone with an existing, unused ephonedn. If no ephonedn is available, the phone will
register but none of the phone’s buttons will be associated with ephonedn extensions.
The autoregephone command, not the auto assign command, configures a router to automatically assign an
ephone to an IP phone. When an IP phone registers with a router that is configured with the autoreg-ephone
command, the router will associate the Media Access Control (MAC) address of the IP phone with the first
unassigned ephone on the router. If all the ephones on the router are associated with IP phones, the router will
create a new ephone, provided that the number of configured ephones does not exceed the value of the
maxephone command. You can also manually assign an IP phone to an ephone by issuing the macaddress
macaddress command in ephone configuration mode, where macaddress is the MAC address of the IP phone
you want to assign to the ephone.
The auto assign command does not configure a router to automatically assign an IP address to an IP phone. A
router that is configured as a Dynamic Host Configuration Protocol (DHCP) server automatically assigns an IP
address to an IP phone. The following partial output from the show runningconfig command displays a DHCP
server that is configured to distribute IP addressing information to IP phones:
ip dhcp excluded-address 192.168.14.1 192.168.14.9
ip dhcp pool IPPhones
network 192.168.14.0 255.255.255.0
default-router 192.168.14.1
option 150 ip 192.168.14.1
The auto assign command does not configure a router to automatically assign an IP phone to a hunt group. IPphones are associated with ephones, ephones are associated with ephonedns, and ephonedns are manually
assigned to hunt groups.
