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 1 and 3 2 and 5 2 and 4 1,3 and 4 1 and 3 2 and 5 2 and 4 ANSWER DOWNLOAD EXAMIANS APP
Computer Networking Using the following illustration, what would be the IP address of E0 if you were using the eighth subnet? The network ID is 192.168.10.0/28 and you need to use the last available IP address in the range. The zero subnet should not be considered valid for this question. 192.168.10.143 192.168.10.66 192.168.10.142 192.168.10.126 192.168.100.254 192.168.10.143 192.168.10.66 192.168.10.142 192.168.10.126 192.168.100.254 ANSWER DOWNLOAD EXAMIANS APP
