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 is most likely to occur if a user dials 911?

A.
The call will connect to the 911 service.

B.
The call will fail because .11 is not a valid destination pattern.

C.
The call will connect to the 411 service because 4 comes before 9.

D.
The call will fail because the forward-digits 3 command is missing.

Explanation:
The call will fail because the forward-digits 3 command is missing from the configuration. The forward-digits 3
command would enable the router to forward N11 service calls to the public switched telephone network
(PSTN). N11 numbers are a group of short telephone numbers that are reserved in the North American
Numbering Plan (NANP) for special services, such as emergency calls, telephone directory information, and
traffic reports. By default, Cisco Unified Communications Manager Express (CME) only forwards digits matchedby wildcards in a destination pattern, not digits that are explicitly defined in the destination pattern. Therefore,
the destination-pattern .11 command configures CME to forward only the first digit in the destination pattern
when a user dials an N11 service code.
The destination pattern in this configuration is valid. The destination-pattern command is used to match both
inbound and outbound dial peers. The sequence of dialed digits that will be matched for a dial peer can contain
the digits 0 through 9, the asterisk (*), and the pound sign (#). In addition, you can use a period (.) as a wildcard
symbol to refine the dialing pattern or to match multiple dial strings for a single dial peer. The command set in
this scenario configures a dial peer on a CME router to match three-digit patterns ending in 11.
The call will not connect to either the 911 service or the 411 service, because the CME router will forward only
the first digit of the number. However, if the forward digits 3 command had been issued on the router, the call
would connect to the 411 service only if the user dialed 411. Destination pattern matching on the. wildcard
matches digits one-by-one as the user dials them; it does not match digits to wildcards in a given sort order.
