Question

Options

• Anum-exp 1234 7222222
• Bvoice-translation profile POTS translate called 1
• Cdial-peer voice 1 pots destination-patter 7...$ port 0/2/0:15
• Dvoice-translation rule 1 rule 1 /^7(.*)$/ /8\1/
• Edial-peer voice 1 pots destination-patter ^7...$ no digit-strip port 0/2/0:15

• A
  27% (9)
• B
  58% (19)
• C
  6% (2)
• E
  9% (3)

Explanation

Digit manipulation in Cisco IOS requires two components working together: (1) A voice translation rule (option D) defines the regex-based substitution - 'rule 1 /^7(.*)$/ /8\1/' matches any number starting with 7, captures the remaining digits, and replaces the leading 7 with 8. (2) A voice translation profile (option B) packages the rule and specifies which number to translate (called, calling, or redirect) - 'voice-translation profile POTS translate called 1' applies translation rule 1 to the called number. The profile is then applied to a dial-peer with 'translation-profile outgoing/incoming POTS'. Options A, C, and E are incorrect: num-exp is for extension expansion, and the dial-peer destination-pattern options shown do not perform digit translation.
