Topic #: 3
Which Ethernet frame can create Layer 2 flooding due to all bytes on the destination MAC address being set to all FF?

Suggested Answer: A Vote an answer

Layer 2 flooding caused by Ethernet frames with all bytes in the destination MAC address set to FF refers to broadcast frames.Here's why:
* Broadcast Ethernet Frame (A):
* Address Specification:In Ethernet networking, a broadcast frame has a destination MAC address ofFF:FF:FF:FF:FF:FF, which instructs network devices to forward the frame to all devices within the broadcast domain.
* Network Behavior:This causes Layer 2 flooding as the frame is sent to all ports in the VLAN, except the originating port, ensuring that the broadcast reaches all network segments.
* Other Frame Types:
* Unicast (B)targets a single device.
* Multicast (C)targets a group of devices.
* Anycast (D)is not used in Ethernet but rather in IP-based routing to route to the nearest of multiple destinations, typically in internet addressing.
References:You can find more information about Ethernet frame types in networking textbooks or documentation that discusses network layer interaction:Network Theory Books
