What is the Layer 2 Broadcast Destination Address?

• A. 192.168.1.255
• B. FFFF.FFFF.FFFF
• C. AABB.CCDD.EEFF
• D. 00FF.00FF.00FF

Answer: (B)

The Layer 2 broadcast destination address in Ethernet networks is represented by the address FFFF.FFFF.FFFF. This address is significant because it indicates that a frame should be forwarded to all devices on the local network segment, rather than targeting a specific device. When a network device sends a frame with the broadcast MAC address, all devices within the same broadcast domain will receive and process this frame. This is essential for various types of network operations, such as ARP (Address Resolution Protocol) requests, where a device needs to discover the MAC address corresponding to a known IP address. The other options provided are not valid Layer 2 broadcast addresses. For instance, the IPv4 broadcast address 192.168.1.255 is used at Layer 3, and while it serves a similar purpose for broadcasting data at the network layer, it is not the correct format for Ethernet Layer 2. The addresses AABB.CCDD.EEFF and 00FF.00FF.00FF are examples of specific unicast addresses and do not represent the broadcast functionality critical to Layer 2 communications.
