Sorry, you selected the wrong answer.

In a NETRIX network, an address can consist of how many digits?

  1. Four digit DNIC plus up to 10 more digits
  2. Only 14 digits according to X.121 standard
  3. Any number of digits from 1 to 15

The CCITT recommended X.121 is a suggestion for Public Data Networks not for private networks.

The CCITT (UTC) recommendation suggest 5 to 14 digits

The correct answer is "Any number of digits from 1 to 15."
