Computer Networking A network administrator views the output from the show ip route command. A network that is advertised by both RIP and IGRP appears in the routing table flagged as an IGRP route. Why is the RIP route to this network not used in the routing table? IGRP has a faster update timer. The IGRP route has fewer hops. RIP has a higher metric value for that route. IGRP has a lower administrative distance. IGRP has a faster update timer. The IGRP route has fewer hops. RIP has a higher metric value for that route. IGRP has a lower administrative distance.

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