Which statement is correct concerning exception traffic processing?

Answer options

• A. Exception traffic is discarded by the PFE.
• B. Exception traffic is rate-limited to protect the RE.
• C. Exception traffic is always dropped during congestion.
• D. Exception traffic is never forwarded.

Correct answer: B

Explanation

The correct answer is B because exception traffic is indeed rate-limited to protect the Routing Engine (RE) from being overwhelmed. Option A is incorrect as the PFE does not discard all exception traffic. Option C is false since exception traffic can be processed even during congestion. Option D is not accurate because exception traffic can be forwarded under certain circumstances.
