You monitor Azure virtual machines by using Azure Monitor.
You plan to restart the virtual machines when CPU usage exceeds 95 percent for more than 30 minutes.
You need to create an alert in Azure Monitor to restart the virtual machines. The solution must minimize administrative effort.
Which type of action should you use in the alert?
To minimize administrative effort while enabling automatic action based on CPU usage, an Automation Runbook is the most suitable choice. Automation Runbooks allow you to create scripts to perform routine tasks such as restarting a virtual machine. These scripts can be integrated directly into Azure Monitor alert rules, allowing them to be triggered automatically when the specified condition (CPU usage exceeds 95 percent for more than 30 minutes) is met. This approach simplifies administration as it leverages pre-configured workflows that can be reused without the need to develop new logic from scratch.
C is correct. Check yourself in Azure Portal -> Monitor -> Create alert rule -> create action -> automation runbook -> select "restart VM" from dropdown. Every easy, no admin effort. If you choose Logic App instead of automation runbook, you actually need to develop/design your logic app to restart the VM, which is more effort.
ITSM - IT Service Management Connector (ITSMC) allows you to connect Azure to a supported IT Service Management (ITSM) product or service. Webhook - Webhook actions allow you to invoke a single HTTP POST request. Logic App - This action is used to invoke a logic app. Answer is C
Correct
"The solution must minimize administrative effort" eq. Logic App
A Logic App can reboot a VM?
Difficult choice I think, runbook and logic app can both do it and are both options in an action group. The whole point of a logic app is that it's simpler because you haven't got to write code. Personally I think I'll go runbook, more orthodox, but I may change my mind!
Correct Use a runbook (to restart a VM, or scale a VM up or down) https://docs.microsoft.com/en-us/learn/modules/incident-response-with-alerting-on-azure/6-activity-log-alerts
"You need to create an alert in Azure Monitor to restart the virtual machines." - Runbooks can be triggered if an alert is generated. But the question relates to triggering the alert. I would go with logic app
C is correct: https://docs.microsoft.com/en-us/azure/automation/automation-alert-metric If you want a simple Alert, use a runbook. If you have a complicated set of rules and logic you need to apply, then use Logic Apps.
Answer is correct. We need Automation Runbook which can be triggered from the Alerts directly and which gets Events or Logs.
