CCNA Question of the Week

In this weekly series, Jill Liles posts questions and answers to help readers prepare for the CCNA exam.

How can you condense consecutive sets of zeros in an IPv6 address?

  1. with the “:::” symbol
  2. by eliminating leading zeros
  3. by replacing four consecutive zeros with a single zero
  4. with the “::” symbol


The correct answer is D.

IPv6 addresses can be shortened by replacing a “bunch” of zeros, only once in an address, with the “::” symbol. This can be done only once because the address is expanded by determining how many bits are missing and putting zeros in their place.
