+## Question 4
+Q: *Alarms are an important part of telemetry monitoring. Describe how they work in
+ThingsBoard and what options are available to send notifications when an alarm is triggered.*
+
+A: Alarms are defined for certain device profiles which you choose. If certain telemetry data is sent that meets certain conditions, the alarm will be triggered. This will be visible in your notifications. The alarms can also be displayed in a dashboard that is associated with a device of the device profile.
+
+Personalized notifications can be delivered via email, SMS or other third party systems through the Notification Center.
+
+It's also possible to send notifications to your smartphone through the Thingsboard Mobile Application
