MEF Software-Defined Wide Area Network (SD-WAN) Practice Exam

What term describes a pause between frames, potentially used for clock syncing or other purposes?

Inter frame gap Ingress IP Packet Egress IP Packet Internet Breakout / Local Internet Breakout

Correct Answer:

Inter frame gap

Explanation:

The pause between Ethernet frames is called the interframe gap. It’s a mandated idle period defined by the Ethernet standards, measured in bit times, that separates consecutive frames. This gap lets devices finish processing the previous frame, prepare and time the next one, and can even aid receivers with timing or clock alignment in some designs. The other terms describe data traffic or routing concepts (IP packets moving in or out of a device, or local Internet breakout) rather than the timing gap between frames. So the interframe gap is the correct term for a pause between frames.
