Select 3You are provided with a network diagram by a network engineer to set up a small office network. The diagram indicates the following connections: a router to a switch, a switch to multiple PCs, and a router to an ISP modem. Which types of cables should you use to correctly connect the devices based on the diagram?
- A
Use a straight-through Ethernet cable to connect the router to the switch.
- B
Use a straight-through Ethernet cable to connect the switch to the PCs.
- C
Use a crossover Ethernet cable to connect the router to the switch.
- D
Use a straight-through Ethernet cable to connect the router to the ISP modem.
- E
Use a crossover Ethernet cable to connect the switch to the PCs.
Show answer and explanation
Correct answers: A, B, D
Explanation
In networking, the type of Ethernet cable used depends on the devices being connected. Straight-through cables are used for connections between devices of different types (e.g., router to switch, switch to PCs, router to ISP modem). Crossover cables are used for connections between devices of the same type (e.g., switch to switch, PC to PC). Understanding the correct cable type is essential to ensure proper network functionality.
- A. Correct.
Correct. A straight-through Ethernet cable is used to connect devices of different types, such as a router to a switch.
- B. Correct.
Correct. A straight-through Ethernet cable is used to connect the switch to end devices like PCs.
- C. Incorrect.
Incorrect. A crossover Ethernet cable is typically used to connect devices of the same type, such as two switches or two PCs. A router and switch are different types of devices.
- D. Correct.
Correct. A straight-through Ethernet cable is generally used to connect a router to an ISP modem, as they are different types of devices.
- E. Incorrect.
Incorrect. A crossover Ethernet cable is not used to connect a switch to end devices like PCs. Straight-through cables are appropriate for this connection.
