Which of the following dial peer commands will match dial strings 1777 and 3777? (Select 3 choices.)

A.
destinationpattern .777

B.
destinationpattern *777

C.
destinationpattern (13)777

D.
destinationpattern [13]777

E.
destinationpattern [13]777

Explanation:
The following dial peer commands will match dial strings 1777 and 3777:
-destinationpattern .777
-destinationpattern [13]777
-destinationpattern [13]777
The destination-npattern command is used to match both inbound and outbound dial peers; a dial peer defines
a logical route to a telephony endpoint. Outbound dial peers are matched to destination patterns on a digit-bydigit basis as the caller dials the destination number. If multiple dial peers explicitly match the destination
pattern, the most specific match for the pattern will be used. 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 the following symbols to refine the dialing pattern or to match multiple dial strings for a single dial peer:

The dial peer command destinationpattern .777 matches any fourdigit dial string that ends with 777. The period
is used as a wildcard character that matches any digit. Not only will the destinationpattern .777 command
match 1777 and 3777, it will also match 0777, 2777, 4777, 5777, and so on.
The dial peer command destinationpattern [13]777 matches only the dial strings 1777 and 3777. When squarebrackets contain a set of digits without a dash, the pattern will match any of the bracketed digits for that digit
position. For example, the destinationpattern [135]777 command matches the dial strings 1777, 3777, and
5777. The caret (^) can be used within the brackets to indicate characters that should not match. For example,
the destinationpattern [^01479]777 command matches the dial strings 2777, 3777, 5777, 6777, and 8777, but
the command does not match the dial strings 0777, 1777, 4777, 7777, and 9777.
The dial peer command destinationpattern [13]777 matches the dial strings 1777, 2777, and 3777. The dash
indicates a range of characters. You can also use the dash along with a set of characters. For example, the
destinationpattern [135]777 command matches the dial strings 1777, 3777, 4777, and 5777.
The dial peer command destinationpattern *777 does not match the dial strings 1777 and 3777. The * character
is not used as a wildcard character? it is used to indicate the asterisk on the telephone keypad. Therefore, the
destinationpattern *777 command matches only the dial string *777.
The dial peer command destinationpattern (13)777 does not match the dial strings 1777 and 3777.
Parentheses are used to indicate a specific sequence of characters. Therefore, the destinationpattern (13) 777
command matches only the dial string 13777. Parentheses are often used with the %, +, and ? characters to
indicate a repeating pattern. For example, the destinationpattern (13)+777 command matches 13777, 1313777,
131313777, and so on.
