- A
Configure Cloud Build triggers to run only from protected branches (e.g., main, release).
This prevents injection of malicious code from feature branches.
- B
Store secrets and credentials in Secret Manager and access them via the 'availableSecrets' field.
Secret Manager provides secure, audited access to secrets.
- C
Grant the Cloud Build service account the Storage Admin role for the project to allow pushing images.
Why wrong: Storage Admin is overly broad; use minimal roles like Artifact Registry Writer.
- D
Enable Container Analysis on the Artifact Registry repository to automatically scan images for vulnerabilities after build.
Scanning helps detect and remediate vulnerabilities early.
- E
Disable build cache to ensure fresh builds and avoid using potentially compromised cached layers.
Why wrong: Disabling cache slows builds and does not significantly improve security; scanning images is more effective.
PCDOE Building and implementing CI/CD pipelines Practice Question
This PCDOE practice question tests your understanding of building and implementing ci/cd pipelines. 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.
Which THREE of the following are best practices for securing a CI/CD pipeline using Cloud Build? (Choose 3.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
Configure Cloud Build triggers to run only from protected branches (e.g., main, release).
Option A is correct because restricting Cloud Build triggers to protected branches (e.g., main, release) prevents unauthorized or untested code changes from initiating builds, which is a fundamental security control for CI/CD pipelines. This ensures that only code that has passed review and is merged into stable branches can trigger automated builds, reducing the risk of malicious or erroneous code being deployed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the principle of least privilege by including overly broad IAM roles (like Storage Admin) as distractors, and candidates may mistakenly think granting full access is acceptable for simplicity, when in fact specific roles like Artifact Registry Writer or Cloud Build Service Account should be used.
Detailed technical explanation
How to think about this question
Cloud Build triggers can be configured with a regex pattern for branch names, and using `^main$` or `^release/.*$` ensures only those branches trigger builds. The `availableSecrets` field in `cloudbuild.yaml` allows referencing secrets from Secret Manager by key, which are injected as environment variables or files at build time without exposing them in the source code or logs. Container Analysis (now part of Artifact Analysis) uses vulnerability scanning based on the Common Vulnerabilities and Exposures (CVE) database and can be integrated with Cloud Build to fail builds if critical vulnerabilities are found.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
