CCNA – Basic Questions
Question 1
For which type of connection should a straight-through cable be used?
A. switch to switch
B. switch to hub
C. switch to router
D. hub to hub
E. router to PC
Answer: C
Explanation
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: use straight-through cable
Two devices in the same group: use crossover cable
In this case we can use straight-through cable to connect a switch to a router -> C is correct.
Question 2
Which type of cable is used to connect the COM port of a host to the COM port of a router or
switch?
A. crossover
B. straight-through
C. rolled
D. shielded twisted-pair
Answer: C
Explanation
The correct question should be “Which type of cable is used to connect the COM port of a host to
the CONSOLE port of a router or switch?” and the correct answer is rollover cable. But we can’t
plug this rollover cable directly into our host because it will not work. We often use a RJ45 to DB9
