A financial firm is experiencing intermittent 'Client Authentication Failures' across multiple sites. The alerts are not correlated in time, and the firm's helpdesk is receiving user complaints. The network team has checked the RADIUS server and found no issues. What is the next best step in the Mist portal to identify the root cause?

Use the 'Marvis' AI assistant to ask about the authentication failures and review the AI-driven insights and suggested root causes.

Increase the severity of 'Authentication Failure' alerts to 'Critical' to get more attention.

Generate a report of all 'Authentication Failure' alerts from the last week and look for a pattern by site.

Acknowledge all the alerts and wait for the issue to resolve itself.

An administrator wants to receive an alert only when the number of failed client authentications exceeds 10 in a 5-minute window. What must be configured in the alert rule?

A threshold of 10 and a time window of 5 minutes

A site assignment for the alert

A large enterprise wants to automate the response to 'Rogue AP' alerts. When a rogue AP is detected, they want to automatically disable the switch port to which the rogue AP is connected. They also want to send a notification to the security team. What is the most effective way to achieve this using Mist?

Create an alert rule for 'Rogue AP' that sends an email to the security team, and rely on them to manually disable the port.

Configure a webhook to send the alert to the SIEM, and have the SIEM disable the switch port.

Configure a webhook for 'Rogue AP' alerts to trigger a script in an external automation platform that disables the switch port and sends a notification.

Use the Mist portal's built-in 'Automation' feature to directly disable the switch port.
