The correct answer is building the container locally and pushing to Artifact Registry, then deploying with gcloud, alongside source-based deployment using the `--source` flag. These two approaches are supported because Cloud Run is designed to accept either a pre-built container image from a registry like Artifact Registry or to automatically build and deploy from your source code, handling the containerization process for you. On the Google Professional Cloud Developer exam, this question tests your understanding of the two primary workflows for getting an application onto Cloud Run, often appearing as a multiple-select item where distractors include unsupported methods like deploying directly from a Dockerfile without a registry or using a CI/CD pipeline that bypasses Artifact Registry. A common trap is assuming that any method involving a Dockerfile is valid, but Cloud Run requires either a built image in a registry or the `--source` flag to trigger a build. Remember the mnemonic "Push or Pull" — you either push a built image to a registry, or you let Cloud Run pull your source and build it.
PCD Building and testing applications Practice Question
This PCD practice question tests your understanding of building and testing applications. 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 company wants to deploy a containerized application to Cloud Run. Which two approaches are supported? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use gcloud beta run deploy with --source flag to build and deploy from source
Cloud Run supports source-based deployment with the `--source` flag and building/pushing to Artifact Registry then deploying. Other options are not valid deployment methods.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use gcloud beta run deploy with --source flag to build and deploy from source
Why this is correct
This allows building and deploying directly from source code.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use Cloud Functions to package the container as a function
Why it's wrong here
Cloud Functions handles code, not containers.
✗
Upload a Dockerfile to Cloud Run console and let it build
Why it's wrong here
Cloud Run console does not build from Dockerfile; it expects a pre-built image.
✗
Use Kubernetes Engine to deploy the container and then migrate to Cloud Run
Why it's wrong here
Migration is not a deployment method; it's a separate process.
✓
Build the container locally and push to Artifact Registry, then deploy with gcloud
Why this is correct
This is the standard workflow: build, push to registry, then deploy.

Common exam traps
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.
Detailed technical explanation
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.
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.
