AZ-204 Practice Question: Connect to and consume Azure services and third-party services

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Create an Azure Container Registry, push the container image to the registry, create a container group in Azure Container Instances, configure the container group settings, then start the container group.

  Why this is correct

  This is correct because the registry must exist before pushing an image, and the image must be in the registry before creating a container group that references it. The container group is created with initial settings, and if needed, additional configuration and starting follow, though in ACI the container starts upon creation.

• ✗

  Push the container image, create an Azure Container Registry, create a container group, configure settings, then start.

  Why it's wrong here

  This sequence is fundamentally flawed because a container image cannot be pushed to a destination that does not yet exist. Azure Container Registry (ACR) serves as the secure, private repository for Docker images. Therefore, the ACR instance must be provisioned and available before any 'docker push' command can successfully upload an image to it, making the initial step of pushing the image impossible.

• ✗

  Create a container group, create an Azure Container Registry, push the container image, configure settings, then start.

  Why it's wrong here

  This order is incorrect because an Azure Container Instance (ACI) container group requires a specific container image to be referenced at the time of its creation. The ACI service pulls this image from a registry, such as Azure Container Registry, to instantiate the containers. Consequently, the image must already be built and pushed to a registry before the container group can be defined and provisioned to utilize it.

• ✗

  Create an Azure Container Registry, create a container group, push the container image, configure settings, then start.

  Why it's wrong here

  While creating the Azure Container Registry first is a correct initial step, this sequence fails because the container group is attempted before the image is actually available within that registry. When creating an Azure Container Instance (ACI) container group, you must specify the image source. If the image has not yet been pushed to the ACR, the ACI deployment will fail as it cannot locate or pull the specified container image from the designated repository.
