What is the hexadecimal representation for an Ethernet Broadcast address?
A
FF-FF-FF-FF-FF-FF
B
00-00-00-00-00-00
C
11-11-11-11-11-11
D
99-99-99-99-99-99
Explanation: 

Detailed explanation-1: -An Ethernet broadcast frame is received and processed by every device on an Ethernet LAN. The features of an Ethernet broadcast are as follows: It has the destination MAC address FF-FF-FF-FF-FF-FF in hexadecimal (or 48 1s in binary). It is flooded out all Ethernet switch ports except the incoming port.

Detailed explanation-2: -When the SW receives the frame, it checks the destination MAC address. For a broadcast address FFFF. FFFF. FFFF it will forward the frame to every port except the port in which the switch received the frame.

Detailed explanation-3: -At the Ethernet layer, broadcast frames have a destination MAC address of FF-FF-FF-FF-FF-FF. When a switch receives a frame with this MAC, it sends a copy of the frame out all its interfaces, except the one it received the broadcast on. An example of this behavior is shown in Figure 1.

Detailed explanation-4: -Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal digits (0-9, plus A-F, capitalized).
