300-430 Question 233
Single answerA network administrator is monitoring a Cisco wireless network and notices that multiple access points are reporting high channel utilization in a specific area. What would be the most appropriate monitoring action to take next to identify the root cause?
- A
Analyze the Radio Frequency (RF) spectrum to identify potential interference sources.
- B
Increase the transmit power of the access points to improve coverage in the area.
- C
Check the access points' firmware version and immediately update to the latest version.
- D
Disable Dynamic Channel Allocation (DCA) to prevent channel changes in the affected area.
Show answer and explanation
Correct answer: A
Explanation
High channel utilization can result from interference, congestion, or environmental factors. The most appropriate monitoring action in this scenario is to analyze the RF spectrum, as it allows the administrator to identify potential interference sources and understand the wireless environment better. This step is critical for diagnosing and resolving issues effectively.
- A. Correct.
Analyzing the RF spectrum helps identify interference sources such as neighboring Wi-Fi networks, non-Wi-Fi devices, or environmental obstacles, which could explain high channel utilization.
- B. Incorrect.
Increasing the transmit power is not appropriate in this case, as it may lead to more interference and worsen the issue rather than improving it.
- C. Incorrect.
Checking and updating the firmware might be a good long-term action, but it is not directly related to identifying the root cause of high channel utilization.
- D. Incorrect.
Disabling DCA could lead to suboptimal performance since it prevents the system from adapting to interference or congestion dynamically.
