- A
docker tag myimage us-central1-docker.pkg.dev/myproject/myrepo/myimage:v1 && docker push us-central1-docker.pkg.dev/myproject/myrepo/myimage:v1
This correctly tags the local image with the full Artifact Registry path and pushes it. The format is `[REGION]-docker.pkg.dev/[PROJECT]/[REPO]/[IMAGE]:[TAG]`.
- B
gcloud artifacts docker push myimage --location=us-central1 --repository=myrepo
Why wrong: `gcloud artifacts docker push` is not a valid command. Docker images are pushed using the standard `docker push` command after tagging.
- C
docker push gcr.io/myproject/myimage:v1
Why wrong: This pushes to Container Registry (gcr.io), not Artifact Registry (pkg.dev). The registry host and path format are different.
- D
gcloud container images push myimage:v1 --region=us-central1
Why wrong: `gcloud container images push` is not a valid command. Use standard `docker tag` and `docker push` commands.
Quick Answer
The correct answer is to use the `docker tag` command followed by `docker push` with the full Artifact Registry path. This is correct because Docker requires a local image to be tagged with the complete registry URL—including the hostname, project ID, repository name, and image name with version tag—before it can be pushed to a remote repository like Artifact Registry. The `docker push` command then authenticates through the configured Docker credential helper and uploads the image to the specified path. On the Google Associate Cloud Engineer exam, this tests your understanding of the standard Docker workflow in a GCP context, where the registry host is always in the format `LOCATION-docker.pkg.dev`. A common trap is forgetting to include the project ID or repository name in the tag, or attempting to push without tagging first. Remember the memory tip: "Tag the full path, then push—never skip the tag."
Google ACE Deploying and implementing a cloud solution Practice Question
This ACE practice question tests your understanding of deploying and implementing a cloud solution. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 team has a Docker container image locally and wants to push it to Google Artifact Registry. They've already authenticated Docker with GCP. The registry host is 'us-central1-docker.pkg.dev'. Which commands correctly tag and push the image?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
docker tag myimage us-central1-docker.pkg.dev/myproject/myrepo/myimage:v1 && docker push us-central1-docker.pkg.dev/myproject/myrepo/myimage:v1
Option A is correct because it uses the standard Docker CLI workflow: first tagging the local image with the full Artifact Registry path (including the registry host, project, repository, and image name with tag), then pushing it. Since the team has already authenticated Docker with GCP, the `docker push` command will authenticate via the Docker credential helper and upload the image to the specified Artifact Registry repository.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✓
docker tag myimage us-central1-docker.pkg.dev/myproject/myrepo/myimage:v1 && docker push us-central1-docker.pkg.dev/myproject/myrepo/myimage:v1
Why this is correct
This correctly tags the local image with the full Artifact Registry path and pushes it. The format is `[REGION]-docker.pkg.dev/[PROJECT]/[REPO]/[IMAGE]:[TAG]`.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
gcloud artifacts docker push myimage --location=us-central1 --repository=myrepo
Why it's wrong here
`gcloud artifacts docker push` is not a valid command. Docker images are pushed using the standard `docker push` command after tagging.
- ✗
docker push gcr.io/myproject/myimage:v1
Why it's wrong here
This pushes to Container Registry (gcr.io), not Artifact Registry (pkg.dev). The registry host and path format are different.
- ✗
gcloud container images push myimage:v1 --region=us-central1
Why it's wrong here
`gcloud container images push` is not a valid command. Use standard `docker tag` and `docker push` commands.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between Google Container Registry (gcr.io) and Artifact Registry (LOCATION-docker.pkg.dev), and candidates mistakenly use gcr.io commands or syntax for Artifact Registry, or assume gcloud commands can replace standard Docker CLI commands for pushing images.
Trap categories for this question
Command / output trap
`gcloud artifacts docker push` is not a valid command. Docker images are pushed using the standard `docker push` command after tagging.
Detailed technical explanation
How to think about this question
Artifact Registry uses a regionalized hostname format (`LOCATION-docker.pkg.dev`) to store images in a specific GCP region, enabling lower latency and compliance with data residency requirements. The Docker credential helper (`gcloud auth configure-docker`) modifies Docker's configuration to automatically exchange GCP credentials for registry access, so `docker push` works seamlessly after authentication. Tagging with the full path is mandatory because Docker uses the registry hostname to determine the target repository, and the project and repository are encoded in the URL path.
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.
TExam Day Tips
- 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.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
