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.
Which TWO are benefits of using Cloud Build? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It allows using custom build steps with community or private images
Option A is correct because Cloud Build allows you to use custom build steps with community or private container images, enabling you to run arbitrary tools and scripts as part of your build pipeline. This flexibility means you are not limited to Google-provided build steps and can integrate any software that runs in a container.
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.
✓
It allows using custom build steps with community or private images
Why this is correct
Custom build steps provide flexibility.
Related concept
Read the scenario before looking for a memorised answer.
✓
It offers a fully managed CI/CD platform for building, testing, and deploying
Why this is correct
Cloud Build is a managed service for build pipelines.
Related concept
Read the scenario before looking for a memorised answer.
✗
It only supports Java and Go runtimes
Why it's wrong here
Cloud Build supports many languages via community or custom build steps.
✗
It requires a trigger to start any build
Why it's wrong here
Cloud Build can be invoked manually via gcloud or API.
✗
It provides a source code repository for version control
Why it's wrong here
Cloud Source Repositories is the repository service.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that Cloud Build is a full CI/CD platform with built-in version control, but it is actually a build service that relies on external repositories for source code management.
Detailed technical explanation
How to think about this question
Cloud Build executes build steps as a series of Docker containers, each step running in a separate container with access to a shared filesystem mounted at /workspace. Custom build steps allow you to use any image from Container Registry or Artifact Registry, enabling integration with tools like SonarQube for code analysis or custom deployment scripts. This containerized approach ensures reproducibility and isolation across build environments.
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.
