100-150 Question 148
Single answerAn engineer has asked you to check the status lights on a Cisco switch to confirm if it is properly connected to the network. You observe that the STAT indicator is solid green, the SPD light is blinking green, and the LINK/ACT light is solid amber. Based on these observations, what is the status of the device?
- A
The device is functioning normally and connected to the network.
- B
The device is experiencing a connectivity issue with the network.
- C
The device is powered on but has a hardware failure.
- D
The device is powered on but has a speed mismatch with the connected device.
Show answer and explanation
Correct answer: B
Explanation
The status lights on a Cisco device provide critical information about its operation. In this scenario, the STAT light being solid green indicates the device is functioning normally, while the SPD light blinking green shows the port is operating at its configured speed. However, the LINK/ACT light being solid amber indicates a connectivity issue, such as the port being disabled or not established a proper link. This points to a network connectivity problem rather than a hardware failure or speed mismatch.
- A. Incorrect.
This is incorrect. A solid amber LINK/ACT light indicates a potential issue, such as no connectivity or a disabled port.
- B. Correct.
This is correct. A solid amber LINK/ACT light typically means there is a connectivity issue with the network, even though the device is powered on and attempting to connect.
- C. Incorrect.
This is incorrect. A hardware failure would likely involve other status indicators, such as specific error codes or blinking patterns on the STAT light.
- D. Incorrect.
This is incorrect. A speed mismatch would typically be indicated by the SPD indicator, but in this scenario, the SPD light is blinking green, which suggests normal operation.
