Practice question 175 of 506 · medium

A new alias portal.contoso.com should follow app01.contoso.com's address changes. Which record type is appropriate for the alias?

Choose the single best answer.

  1. A.CNAME targeting app01.contoso.com
  2. B.A record containing the text app01.contoso.com
  3. C.NS for portal.contoso.com as if it were the zone authority
  4. D.PTR targeting app01.contoso.com in the forward zone
Show the answer and explanation

✓ Correct answer

  • CNAME targeting app01.contoso.com

CNAME points the alias to the canonical name so that target resolution determines the address. PTR is for reverse mapping, NS identifies zone authority, and an A record stores an IPv4 address rather than a DNS-name target.
