CCIE Routing and Switching (legacy) — Question 24

Which action does a switch running OpenFlow take when it receives a packet that does not match its flow entry?

Answer options

• A. Flood the packet
• B. Transfer the packet
• C. Reject the packet
• D. Drop the packet
• E. Forward the packet to the controller

Correct answer: B

Explanation

The correct answer is B, as a switch running OpenFlow typically transfers the packet to the controller for further processing when it doesn't match any flow entry. Options A, C, D, and E do not accurately describe the action taken for unmatched packets in this context.
