Computer Networking You connect a host to a switch port, but the new host cannot log into the server that is plugged into the same switch. What could the problem be? The host has an invalid MAC address. The router is not configured for the new host. The VTP configuration on the switch is not updated for the new host. The switch port the host is connected to is not configured to the correct VLAN membership. The host has an invalid MAC address. The router is not configured for the new host.

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. 2 and 4 2 and 5 1 and 3 1,3 and 4 2 and 4 2 and 5 1 and 3 1,3 and 4 ANSWER DOWNLOAD EXAMIANS APP
