What function does DiffServ perform?

  • A It automatically identifies traffic.
  • B It guarantees end-to-end bandwidth for traffic.
  • C It categorizes traffic.
  • D It provides reserve bandwidth by using RSVP.
Explanation

DiffServ classifies traffic into behavior aggregates, typically using DSCP markings, so network devices can apply different per-hop forwarding treatments. It does not inherently reserve bandwidth or guarantee an end-to-end bandwidth level.
