47_Straight-Through and Cross-Over cables Quiz

What is the common name for a straight-through cable used to connect workstations to network devices?

• Coaxial cable

• Twisted pair cable

• Fiber optic cable

• Patch cable

Answer explanation

The common name for a straight-through cable used to connect workstations to network devices is a Patch cable.

Which pins are used for 10-megabit and 100-megabit networking in a straight-through cable?

• Pins 3 and 6

• Pins 4, 5, 7, and 8

• All 8 pins

• Pins 1 and 2

Answer explanation

In a straight-through cable, pins 1 and 2 are used for 10-megabit and 100-megabit networking. These pins are responsible for transmitting and receiving data in Ethernet connections.

What is the technical term for the adapter inside a computer that serves as a media-dependent interface?

• Network interface card

• Patch panel

• Network switch

• MDI-X

Answer explanation

The technical term for the adapter inside a computer that serves as a media-dependent interface is a Network Interface Card (NIC). It allows the computer to connect to a network using a specific media type.

In a gigabit Ethernet cable, how many pairs of wires are used for communication?

• 2 pairs

• 4 pairs

• All 8 pairs

• 3 pairs

Answer explanation

In a gigabit Ethernet cable, all 8 pairs of wires are used for communication, making it the correct choice.

When connecting two MDI devices or two MDI-X devices, which type of cable should be used?

• Straight-through cable

• Coaxial cable

• Fiber optic cable

• Crossover cable

Answer explanation

When connecting two MDI devices or two MDI-X devices, a crossover cable should be used to swap the transmit and receive signals between the devices.

What feature allows modern Ethernet devices to automatically identify when a crossover cable is needed?

• Auto-switching

• Auto-MDI-X

• Patch panel detection

• Crossover auto-sense

Answer explanation

Auto-MDI-X is the feature that allows modern Ethernet devices to automatically identify when a crossover cable is needed.

Which devices would require the use of a crossover cable when connecting them together?

• Workstation to switch

• Switch to switch

• Router to switch

• Workstation to router

Answer explanation

Switch to switch is the correct choice because when connecting two switches together, a crossover cable is needed to ensure proper communication since switches transmit on the same pins.

What is the configuration of a crossover cable for 1000BASE-T based on the 802.3 standard?

• Not 568A or B colors

• 568A on one side, 568B on the other

• 568B on both sides

• Custom color coding

Answer explanation

Not 568A or B colors

In gigabit networking, how does the communication flow differ from 10 and 100-megabit Ethernet?

• Transmit on all wires, receive on separate wires

• Transmit and receive on separate wires

• Transmit and receive on all wires

• Transmit on one side, receive on the other

Answer explanation

In gigabit networking, the communication flow involves transmitting and receiving data on all wires, which differs from 10 and 100-megabit Ethernet where the communication flow is not on all wires.

When connecting a workstation to a switch, which type of cable should be used?

• Fiber optic cable

• Coaxial cable

• Crossover cable

• Straight-through cable

Answer explanation

When connecting a workstation to a switch, a straight-through cable should be used to ensure proper communication between the devices.
