300-430 Question 300
Single answerAn enterprise network administrator is using Cisco DNA Center to troubleshoot a connectivity issue for a wireless client. The administrator navigates to the 'Client 360' view in DNA Center and notices that the client has a poor RSSI and high interference levels. What is the most appropriate action the administrator should take using Cisco DNA Center to address this issue?
- A
Use the RF Spectrum Analysis tool to identify the source of interference and adjust the channel plan accordingly.
- B
Increase the transmit power of nearby access points to improve the client’s RSSI.
- C
Enable Fast Lane in DNA Center to prioritize the client’s wireless traffic.
- D
Replace the client device's wireless adapter to resolve the poor RSSI issue.
Show answer and explanation
Correct answer: A
Explanation
The RF Spectrum Analysis tool in Cisco DNA Center is specifically designed to detect sources of interference in the wireless environment. By identifying and mitigating interference, the administrator can improve the client’s wireless performance and potentially resolve both the poor RSSI and interference issues. Adjusting the channel plan is a key step to optimizing wireless network performance.
- A. Correct.
Using the RF Spectrum Analysis tool in DNA Center will allow the administrator to identify sources of interference and adjust the channel plan, which directly addresses the interference and potentially improves RSSI.
- B. Incorrect.
Increasing the transmit power of nearby access points may lead to co-channel interference and is not the recommended first step for resolving poor RSSI or interference issues.
- C. Incorrect.
Enabling Fast Lane is used to prioritize application traffic but does not resolve issues with RSSI or interference that are impacting connectivity.
- D. Incorrect.
Replacing the client device’s wireless adapter is not an appropriate step without first diagnosing and addressing network environment issues.
