Incorrect answer: ACDE
For the destination to be represented in a global form common to all cases, we must adopt a global
form of the destination number from which all local forms can be derived. The + sign is the
mechanism used by the ITU’s E.164 recommendation to represent any PSTN number in a global,
unique way. This form is sometimes referred to as a fully qualified PSTN number.
