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 team uses GitHub for source control. They want to automatically trigger Cloud Build builds on pull request creation. Which two actions are required? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Install the Cloud Build GitHub app in the repository
Installing the Cloud Build GitHub app and creating a trigger with the 'pull_request' event are the two necessary steps. Other options are either not needed or incorrect.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Read the scenario before looking for a memorised answer.
✗
Configure a webhook in GitHub to send push events to Cloud Build
Why it's wrong here
The GitHub app handles webhooks automatically; manual webhook setup is not needed.
✗
Use Cloud Source Repositories as a mirror of GitHub
Why it's wrong here
This is not required and adds unnecessary complexity.
✗
In the Cloud Build trigger, set the event to 'push' and branch filter to 'pull-request/*'
Why it's wrong here
This would trigger on pushes to branches named 'pull-request/*', not on pull request events.

KKey Concepts to Remember
Read the scenario before looking for a memorised 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.
