You have an application that is running in a managed instance group. Your development team has released an updated instance template which contains a new feature which was not heavily tested. You want to minimize impact to users if there is a bug in the new template. How should you update your instances?

1. A. Manually patch some of the instances, and then perform a rolling restart on the instance group.
2. B. Using the new instance template, perform a rolling update across all instances in the instance group. Verify the new feature once the rollout completes.
3. C. Deploy a new instance group and canary the updated template in that group. Verify the new feature in the new canary instance group, and then update the original instance group.
4. D. Perform a canary update by starting a rolling update and specifying a target size for your instances to receive the new template. Verify the new feature on the canary instances, and then roll forward to the rest of the instances. — đáp án hiện tại
