300-445 Question 228
Select 3You are an enterprise network engineer tasked with ensuring a seamless end-user experience. The organization frequently experiences performance issues during peak hours due to high CPU utilization on core network devices and sporadic Wi-Fi connectivity problems. To proactively address these issues, which alert rules should you configure to monitor and mitigate the impact on end-users?
- A
Set an alert rule to trigger when CPU utilization on core devices exceeds 80% for more than 5 minutes.
- B
Configure a rule to monitor and alert when users switch between wired and wireless connections more than 5 times in 10 minutes.
- C
Enable a browser behavior alert rule to detect when users attempt to access unsupported browsers.
- D
Set an alert to monitor VPN tunnel drops exceeding a threshold of 10 disconnections per hour.
- E
Create an alert that triggers when Wi-Fi signal strength for any user drops below the -70 dBm threshold.
Show answer and explanation
Correct answers: A, D, E
Explanation
To ensure a seamless end-user experience, network assurance requires proactive monitoring of key performance indicators such as CPU utilization on core devices, VPN stability, and Wi-Fi signal strength. These metrics directly impact user connectivity and performance. While browser behavior and transition between connection types may have some influence, they are not as critical as the other metrics in the context of network performance monitoring.
- A. Correct.
Setting an alert rule for CPU utilization exceeding 80% ensures proactive monitoring of high resource usage, which could lead to degraded network performance for end-users.
- B. Incorrect.
Monitoring user transitions between wired and wireless connections is not typically a critical factor in end-user experience unless it is directly tied to connectivity issues, which is not mentioned here.
- C. Incorrect.
While monitoring unsupported browser usage can improve security and application compatibility, it is not directly related to network performance or the scenarios described in the question.
- D. Correct.
Monitoring VPN tunnel drops is crucial for remote users as frequent disconnections can severely affect their experience, especially during peak hours.
- E. Correct.
Wi-Fi signal strength below -70 dBm can lead to poor connectivity and performance issues, so this alert is essential for maintaining a good end-user experience.
