C. Create and run an Azure Container Registry task. Can automatically build and update container images whenever the base image is changed. >Enable Task in ACR -ACR tasks allow you to automate container image builds whenever there are changes to the base image. >Create ACR Task -Automating actions based on changes in external container registries like Docker Hub. >Save and Run Task Run the task manually, this will be automatically triggered whenever the base image is updated in Docker Hub. https://learn.microsoft.com/en-us/azure/container-registry/container-registry-tasks-base-images I think you can achieve the same using Docker Hub service connection in Azure Pipelines, but involves a lot more configuration than using Azure Container Registry task.

C is the answer. https://learn.microsoft.com/en-us/azure/container-registry/container-registry-tasks-overview#task-scenarios

Yes, creating a Docker Hub service connection in Azure Pipelines is also a valid approach to automatically update Image1 whenever the base image is updated on Docker Hub. Here are the steps you can follow: In Azure DevOps, navigate to the Project Settings > Service connections. Click the "New service connection" button, and select "Docker Registry". Enter the Docker Hub registry URL and credentials. Save the service connection. In your build pipeline, add a Docker task to build and push the Image1 container to ACR1. In the Docker task, specify the base image from Docker Hub in the "FROM" statement in your Dockerfile. Enable the "Use Cache" option in the Docker task to speed up the build process..

Creating and running an Azure Container Registry task is one approach you could take to update Image1 automatically whenever the base image is updated on Docker Hub. Here is an example of how you could do this: In your build pipeline in Azure DevOps, add an Azure Container Registry task to the build step that generates Image1. In the Azure Container Registry task, specify the container registry (ACR1) where Image1 is stored and the name of the base image on Docker Hub. Set the task to check for updates to the base image on Docker Hub before building Image1. Save the changes to your build pipeline and run the pipeline to build and push Image1 to ACR1. Verify that the Azure Container Registry task updates Image1 automatically whenever the base image is updated on Docker Hub.

C is correct answer.

correct answer

got this in 30 Jun 2021 exams. scored 800+ marks. C is correct

Base images from a public repo in Docker Hub or MCR - For base images in public repositories, an ACR task checks for image updates at a random interval of between 10 and 60 minutes. Dependent tasks are run accordingly. https://docs.microsoft.com/en-us/azure/container-registry/container-registry-tasks-base-images#base-image-notifications

ACR Tasks supports automated container image builds when a container's base image is updated, such as when you patch the OS or application framework in one of your base images. ACR is the answer
