300-445 Question 225
Select 3You are tasked with configuring alert rules in a network assurance platform for an enterprise environment. The goal is to monitor and notify administrators about conditions that could impact end-user experience. Which of the following alert rules should you configure to achieve this objective?
- A
Set an alert for when CPU utilization on a critical network device exceeds 85% for more than 5 minutes.
- B
Enable an alert to detect when users switch from a wired connection to a wireless connection.
- C
Configure an alert to track when VPN latency exceeds 200ms for a sustained period.
- D
Create an alert to monitor when a browser is using excessive memory on end-user devices.
- E
Set an alert for packet loss exceeding 0.5% on a core network switch.
Show answer and explanation
Correct answers: A, B, C
Explanation
To ensure a positive end-user experience, it is essential to configure alert rules that monitor critical infrastructure metrics (like CPU), connectivity changes (such as wired to wireless), and network performance (like VPN latency). These metrics directly influence the quality of the user's interaction with the network. Options like browser memory usage and packet loss, while important, do not align directly with monitoring the end-user experience in a network assurance context.
- A. Correct.
CPU utilization exceeding a threshold can degrade network performance and impact end-user experience, making this a valid alert to configure.
- B. Correct.
Switching from a wired to a wireless connection can affect connectivity quality and user experience, so monitoring this is relevant.
- C. Correct.
High VPN latency can severely impact remote user experience, making this alert critical for ensuring consistent performance.
- D. Incorrect.
While excessive browser memory usage is an issue, it is typically outside the scope of network assurance configurations.
- E. Incorrect.
Packet loss on a core network switch is a critical issue but is more related to network health rather than direct end-user experience.
