Cisco CCNA mock exam questions sample test – Question 439

.You are the network administrator for your company. You wanted to connect the host computers to the switches.
Which cable should you use to ensure the connectivity?

A. Straight-through cable
B. Rollover cable
C. Crossover cable
D. Serial cable

Correct Answer: A

A straight-through cable is a normal four-pair cable with the same order of pin configuration on both ends. These are usually used to connect a computer to the switch or hub’s
Ethernet ports. The following table shows the pin layout of a straight-through cable:
A rollover cable, also known as rolled cable or Cisco console cable, is used to connect a computer terminal to the console port of a router. The cable pin order at one end of the cable
is the reverse of the order at another end. Pin 1 is connected to pin 8, pin 2 to pin 7, and so on.
A crossover cable is used to connect two similar devices such as a computer to computer or a switch to a switch, and a computer to a router’s Ethernet port.
A serial cable is used on a router’s wide area network (WAN) interface to connect to the serial ports. Cisco serial cables generally have a male DB-25 connector on one end and a
female DB-25 connector on the other.
