You issue the show running-config command on a CME router and receive the following partial output:
Examine the output, and use the information you gather to answer the question.
Which of the following statements is true? (Select the best answer.)
A.
There will be no delay after the phone number is dialed.
B.
IP phones will not be able to download their configurations.
C.
IP phones will require manual IP address configuration.
D.
No dialed digit can be matched.
Explanation:
IP phones will not be able to download their configurations from a Trivial File Transfer Protocol (TFTP) server,
because the option 150 ip ipaddress command is missing from the Dynamic Host Configuration Protocol
(DHCP) configuration in the output above. To automatically assign a TFTP server to IP phones, you shouldissue the option 150 ip ipaddress command, where ipaddress is the address of the TFTP server. A TFTP
server is required so that IP phones can download their startup configuration files. In this scenario, the option
150 ip 192.168.14.1 command would configure the DHCP server on the Cisco Unified Communications
Manager Express (CME) router to assign the TFTP server address of 192.168.14.1 to IP phones that are
configured by using DHCP.
There will be a delay after the called number is dialed, and up to 32 digits will be matched by the destination
pattern. The dial peer command destinationpattern .T is used to indicate any string of up to 32 digits. The T
character is used at the end of a string to instruct the router to wait for the complete dial string to be entered
before matching a call to a dial peer. Cisco recommends that you use the destinationpattern .T command
rather than the destinationpattern T command because the destinationpattern .T command requires that the
caller dial a digit.
IP phones will not require manual IP address configuration. The ip address 192.168.14.1 255.255.255.0
command configures the FastEthernet 0/0 interface on the CME router with the IP address 192.168.14.1. In
addition, the ip dhcp excludedaddress 192.168.14.1 192.168.14.9 command prevents the CME router from
assigning the IP address 192.168.14.1 to an IP phone.https://www.cisco.com/c/en/us/td/docs/ios/12_2/ip/configuration/guide/fipr_c/1cfdhcp.html#wp1010670
