NSE 6 – FortiSwitch 7.2 — Question 20

Which Ethernet frame can create Layer 2 flooding due to all bytes on the destination MAC address being set to all FF?

Answer options

• A. The broadcast Ethernet frame
• B. The unicast Ethernet frame
• C. The multicast Ethernet frame
• D. The anycast Ethernet frame

Correct answer: A

Explanation

The correct answer is A, as a broadcast Ethernet frame is designed to reach all devices on the local network segment by using a destination MAC address of all FF. The unicast frame (B) targets a specific device, and multicast (C) and anycast (D) frames do not cause flooding since they target groups or specific nodes, respectively.
