Selected Answer: AF

A F CORRECT A. pattern match: ({6}\d): This pattern match captures an incoming 6-digit E.164 address. The expression {6} specifies exactly 6 digits, and \d represents a digit (0-9). So, this pattern matches any number that has exactly 6 digits. F. replace string: \[email protected]: The \1 refers to the captured group in the pattern match (the 6-digit E.164 address). The @cisco.com is appended to the 6-digit number, forming a SIP URI like [email protected].
