A university campus uses Juniper Mist to manage its wireless network. The IT team wants to be alerted when the signal-to-noise ratio (SNR) on any access point drops below 15 dB, but they do not want to be alerted for individual client issues. Which type of alert rule should they configure?

WLAN alert rule with a threshold for SNR

Client alert rule for roaming events

Device alert rule for AP hardware failures

WAN alert rule for uplink bandwidth

A network administrator wants to programmatically retrieve a list of active alerts from Juniper Mist to integrate with an internal dashboard. Which method should they use?

Use the Mist API to query the alerts endpoint

Use the syslog server to receive alert logs

Export alerts from the dashboard as a CSV file

Configure a webhook to send alerts to the dashboard

An administrator receives an alert indicating that an access point's CPU utilization is above 90%. What is the first step in using this alert to troubleshoot the issue?

Immediately reboot the access point

Change the alert threshold to a higher value

Review the alert details to identify the affected AP and the time of the event

A network administrator is reviewing alerts in the Mist dashboard and notices that some alerts are marked as 'cleared' while others are 'active'. The administrator wants to understand why an alert was cleared. What should they do?

Click on the alert to view its details, including the clear reason

Check the audit log for the alert clear event

Look at the site's WLAN health report

Contact Juniper support for the clear reason

A network engineer is troubleshooting an alert that indicates a high number of DHCP failures on a specific SSID. The alert details show that the DHCP server is reachable, but clients are not getting IP addresses. The engineer suspects a misconfiguration in the SSID's DHCP options. Which alert detail would be most useful to confirm this suspicion?

The client's signal strength at the time of failure

The AP's channel and power settings

The DHCP server's IP address and the SSID's DHCP option settings

The list of clients that failed DHCP and their MAC addresses
