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 about the dial peer configuration is true? (Select the best answer.)
- The dial peer number is invalid.
- The destination pattern is invalid.
- The wrong keyword has been used to define the session target.
- The session target is the same as the default router.
The wrong keyword has been used to define the session target. Dial peer session targets can be specified by IP address or by host name. To specify a session target by IP address, you should configure the session target ipv4:ipaddress command, where ip address is the IP address of the router to which an outbound call matching the dial peer should be forwarded. To specify a session target by host name, you should configure the session target dns: hostname command, where hostname is the alphanumeric host name that is mapped to an IP address by a Domain Name System (DNS) server. The dns keyword also supports some wildcard options.
A voice gateway router will perform the following evaluations when it must send an outbound call:
1. The router will attempt to match the destination Dialed Number Identification Service (DNIS) to a destinationpattern string command on a digitbydigit basis, comparing the digit string to the destination pattern as the user dials the digits.
2. If the dial peer is a plain old telephone service (POTS) dial peer, the router will forward the call to the port indicated by the corresponding portport command.
3. If the dial peer is a Voice over IP (VoIP) dial peer, the router will forward the call to the IP address indicated by the corresponding session target ipv4: ipaddress command.
4. If no match is found, the call will be dropped.
The dial peer number is not invalid. A VoIP dial peer can be configured with any number in the range from 1 through 2145483647.
The destination pattern is not invalid. The dial peer command destination-pattern .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.
The session target is not the same as the default router in this configuration. The default router is defined by the Dynamic Host Configuration Protocol (DHCP) defaultrouter 192.168.14.1 command. The session target is misconfigured and is therefore unlikely to map a host name of 192.168.14.11 to the default router’s IP address of 192.168.14.1.
