ACE Practice Question: A development team stores Docker images in…
This ACE practice question tests your understanding of a development team stores docker images in…. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A development team stores Docker images in Artifact Registry. A new team member needs to pull images to their local machine using Docker. Which command authenticates Docker to pull from a specific Artifact Registry repository in us-central1?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
gcloud auth configure-docker us-central1-docker.pkg.dev
This command configures Docker's credential helper to use gcloud credentials for the specified Artifact Registry endpoint — no key file needed if the user is authenticated with `gcloud auth login`.
B
Distractor review
kubectl create secret docker-registry artifactregistry --server=us-central1-docker.pkg.dev
This creates a Kubernetes pull secret for cluster use — it doesn't configure Docker on the developer's local machine.
C
Distractor review
gcloud artifacts docker auth --region=us-central1
`gcloud artifacts docker auth` is not a valid command. Authentication is done via `gcloud auth configure-docker`.
D
Distractor review
docker login us-central1-docker.pkg.dev --username=_json_key --password-stdin < key.json
While possible with a service account JSON key, this is the legacy approach. `gcloud auth configure-docker` is the recommended keyless method for authenticated users.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

What is the correct answer to this question?
The correct answer is: gcloud auth configure-docker us-central1-docker.pkg.dev — `gcloud auth configure-docker [REGION]-docker.pkg.dev` configures Docker's credential helper to authenticate to Artifact Registry in the specified region. After running this, `docker pull` commands succeed for images in that registry.
What should I do if I get this ACE question wrong?
Identify which ACE exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
