300-445 Question 231
Select 3You are tasked with configuring alert rules for an enterprise network to monitor and improve the end-user experience. The organization has reported issues such as high CPU utilization on network devices, frequent Wi-Fi connectivity drops, and inconsistent VPN performance during remote work hours. Which alert rules should you configure to address these concerns?
- A
Set an alert for CPU utilization exceeding 85% on critical network devices.
- B
Configure an alert for Wi-Fi disconnection rates exceeding 5% of client devices within a 30-minute window.
- C
Create an alert for VPN latency exceeding 100ms during peak hours.
- D
Enable an alert for browser cache size exceeding 500MB for end-users.
- E
Set an alert for wired-to-wireless transition rates exceeding 10% of clients in a single hour.
Show answer and explanation
Correct answers: A, B, C
Explanation
The correct alert rules focus on issues that directly impact the end-user experience in an enterprise network, such as device performance (CPU utilization), network connectivity (Wi-Fi disconnection), and remote access performance (VPN latency). Monitoring browser cache size and wired-to-wireless transition rates are either unrelated or less impactful for network assurance in the given context.
- A. Correct.
Monitoring CPU utilization is critical for ensuring that network devices operate efficiently and do not become a bottleneck, directly affecting user experience. Setting an alert for CPU usage exceeding 85% is a best practice.
- B. Correct.
High Wi-Fi disconnection rates can significantly impact end-user experience. Configuring an alert for disconnection rates exceeding 5% helps identify and address potential wireless network issues.
- C. Correct.
VPN latency can degrade the remote work experience for end-users. An alert for latency exceeding 100ms during peak hours ensures proactive monitoring and resolution of VPN performance issues.
- D. Incorrect.
Browser cache size exceeding 500MB is not directly related to network assurance. This might be relevant for endpoint management but does not address the core network-related user experience issues.
- E. Incorrect.
Wired-to-wireless transition rates are generally normal in hybrid environments and do not typically indicate a problem unless accompanied by other performance issues. Monitoring this alone does not significantly improve the end-user experience.
