100-150 Question 168
Select 3A network technician is troubleshooting a connectivity issue and needs to identify the ports available on a switch. Which of the following ports are most commonly found on modern network switches?
- A
RJ-45 Ethernet ports
- B
Serial Console port
- C
USB Type-C port
- D
HDMI port
- E
SFP (Small Form-factor Pluggable) ports
Show answer and explanation
Correct answers: A, B, E
Explanation
Modern network switches typically include RJ-45 Ethernet ports for general connectivity, Serial Console ports for management and configuration, and SFP ports for high-speed connections over fiber or Ethernet. HDMI ports are not relevant to networking devices, and USB Type-C is not a standard feature on most switches.
- A. Correct.
RJ-45 Ethernet ports are standard on network switches for connecting devices using twisted pair cables. They are crucial for typical network operations.
- B. Correct.
The Serial Console port is often present on network devices like switches and routers to allow direct management and configuration via command-line interfaces.
- C. Incorrect.
USB Type-C ports are less common on network switches and are generally not used for core networking functionality. They might be present on some high-end devices for auxiliary purposes.
- D. Incorrect.
HDMI ports are not found on network switches, as they are used for video output and are irrelevant to networking hardware.
- E. Correct.
SFP ports are common on modern switches for allowing fiber optic or high-speed Ethernet connections via modular transceivers.
