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 TWO are best practices for implementing CI/CD on Google Cloud?
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 the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Artifact Registry for storing container images.
Option B is correct because Artifact Registry is the recommended service for storing, managing, and securing container images and other artifacts in Google Cloud. It integrates natively with Cloud Build, Cloud Run, and Kubernetes, providing vulnerability scanning and IAM-based access control, which are essential for a secure CI/CD pipeline.
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 Cloud Run for all services.
Why it's wrong here
Cloud Run is for serverless containers, not all workloads.
✓
Use Artifact Registry for storing container images.
Why this is correct
Artifact Registry is the recommended registry for Google Cloud.

✗
Use Cloud Build for all deployments, including infrastructure changes.
Why it's wrong here
Cloud Build is not designed for all deployment scenarios; use specialized tools.

✗
Use GitHub Actions instead of Cloud Build.
Why it's wrong here
GitHub Actions is an alternative but not a best practice specific to Google Cloud.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between CI/CD tools and compute services, so candidates mistakenly select Cloud Run as a CI/CD best practice because it is a popular Google Cloud service, but it is a runtime environment, not a pipeline component.

Scenario analysis trap
Cloud Build is not designed for all deployment scenarios; use specialized tools.
Detailed technical explanation
How to think about this question
Artifact Registry supports multiple formats (Docker, Maven, npm, Python, etc.) and uses regional or multi-regional repositories to reduce latency and comply with data residency requirements. It also integrates with Binary Authorization to enforce deployment policies based on attestations, which is critical for regulated environments. Cloud Deploy (option D) is correct because it provides managed continuous delivery for GKE and Anthos, supporting canary and blue-green deployments with automated rollback and Skaffold-based configuration.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
