Computer Networking If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame? Add the source address and port to the MAC address table and forward the frame out the destination port Add the destination to the MAC address table and then forward the frame Flood the network with the frame Discard it and send an error message back to the originating host Add the source address and port to the MAC address table and forward the frame out the destination port Add the destination to the MAC address table and then forward the frame Flood the network with the frame Discard it and send an error message back to the originating host ANSWER DOWNLOAD EXAMIANS APP

Computer Networking How does a host on an Ethernet LAN know when to transmit after a collision has occurred?1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.3. You can improve the CSMA/CD network by adding more hubs.4. After a collision, the station that detected the collision has first priority to resend the lost data.5. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data. 1,3 and 4 2 and 5 1 and 3 2 and 4 1,3 and 4 2 and 5 1 and 3 2 and 4 ANSWER DOWNLOAD EXAMIANS APP
