Alcatel-Lucent NRS II – IP/MPLS Services — Question 27

Which action does the packet remarking process perform?

Answer options

• A. It determines the packet’s forwarding class based on classification criteria
• B. It modifies the current packet’s forwarding class to indicate promotion or demotion
• C. It sets the TOS, DSCP, EXP, or Dot1p field based on classification criteria
• D. It modifies the current TOS, DSCP, EXP, or Dot1p marking to indicate promotion or demotion

Correct answer: C

Explanation

The correct answer is C because the packet remarking process is responsible for setting the TOS, DSCP, EXP, or Dot1p field based on specific classification criteria. Options A and B focus on determining or altering the forwarding class, which is not the primary function of packet remarking. Option D suggests modifying existing markings, which is not the central task of packet remarking either.
