Correct Answer:

Explanation:
To remember which type of cable you should use, follow these tips:
-To connecttwo serial interfacesof 2 routers we useserial cable
- To specify when we use crossover cable or straight-through cable, we should remember: Group 1:Router, Host, Server Group 2:Hub, Switch One device in group 1 + One device in group 2: usestraight-through cable Two devices in the same group: usecrossover cable For example: we use straight-through cable to connect switch to router, switch to host, hub to host, hub to server... and we use crossover cable to connect switch to switch, switch to hub, router to router, host to host...)
