Microsoft Azure IoT Developer — Question 41

You need to update the IoT Edge runtime by using rolling tags.

Which two actions should you perform? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Answer options

• A. On the IoT Edge device, remove the edgeHub and edgeAgent container images.
• B. Modify the systemModules section of the deployment manifest JSON file.
• C. On the IoT Edge device, update the security daemon.
• D. Add an update tag to the IoT Edge device twin.

Correct answer: A, C

Explanation

Removing the edgeHub and edgeAgent container images (Option A) ensures that the old versions are not used during the update process. Updating the security daemon (Option C) is also crucial as it maintains the security aspect during the runtime update. The other options do not directly contribute to the rolling update process for the IoT Edge runtime.
