300-425 Question 250
Select 3An enterprise network administrator is using Cisco Prime Infrastructure (PI) to monitor and manage their wireless network. The administrator notices that a specific access point (AP) frequently goes offline. They want to use PI to investigate and identify the root cause of the issue. Which of the following actions should the administrator take within Cisco PI to troubleshoot this problem?
- A
Review the AP’s event logs in Cisco Prime Infrastructure to check for disconnection patterns.
- B
Use Cisco PI’s Spectrum Analysis tool to identify potential interference near the AP.
- C
Check the AP’s configuration in Cisco PI for incorrect settings or mismatched firmware versions.
- D
Run a Wireless Heatmap report in Cisco PI to analyze coverage gaps in the area served by the AP.
- E
Use the AP's CLI via SSH to directly troubleshoot the hardware issue.
Show answer and explanation
Correct answers: A, B, C
Explanation
Cisco Prime Infrastructure provides advanced tools for monitoring and troubleshooting wireless networks, including event logs, spectrum analysis, and configuration checks. These capabilities allow network administrators to identify and resolve issues related to AP disconnections in a centralized manner. Running a Wireless Heatmap report focuses on coverage analysis rather than root cause troubleshooting, and accessing the AP's CLI is outside the scope of PI's functionality.
- A. Correct.
Reviewing the AP’s event logs in Cisco Prime Infrastructure can reveal disconnection patterns, such as power issues, network interruptions, or firmware crashes.
- B. Correct.
Using Cisco PI’s Spectrum Analysis tool helps detect interference or environmental factors that might be affecting the AP's performance.
- C. Correct.
Checking the AP’s configuration for mismatched firmware or incorrect settings in Cisco PI is critical since configuration errors can lead to frequent disconnections.
- D. Incorrect.
Running a Wireless Heatmap report in Cisco PI is helpful for identifying coverage gaps but does not directly address the root cause of an AP going offline.
- E. Incorrect.
Using the AP's CLI via SSH is not a function provided directly by Cisco Prime Infrastructure. Troubleshooting hardware issues via CLI would require separate access, outside of PI.
