- A
Step 1: Create a Cloud Storage bucket. Step 2: Write the Cloud Function code. Step 3: Deploy the Cloud Function with the appropriate event trigger. Step 4: Test the function by uploading a file to the bucket.
This is the correct order because you need a bucket first to trigger events, then write the code, deploy it with the trigger configuration, and finally test by uploading a file.
- B
Step 1: Write the Cloud Function code. Step 2: Create a Cloud Storage bucket. Step 3: Deploy the Cloud Function with the appropriate event trigger. Step 4: Test the function by uploading a file to the bucket.
Why wrong: This is incorrect because the bucket must exist before deploying the function, as the trigger references the bucket. Writing code first is fine, but creating the bucket after deployment would cause the deployment to fail if the bucket doesn't exist.
- C
Step 1: Create a Cloud Storage bucket. Step 2: Write the Cloud Function code. Step 3: Test the function by uploading a file to the bucket. Step 4: Deploy the Cloud Function with the appropriate event trigger.
Why wrong: This is incorrect because testing before deployment is not possible; the function must be deployed first to be triggered by the upload event.
- D
Step 1: Deploy the Cloud Function with the appropriate event trigger. Step 2: Create a Cloud Storage bucket. Step 3: Write the Cloud Function code. Step 4: Test the function by uploading a file to the bucket.
Why wrong: This is incorrect because you cannot deploy a function without code, and the bucket must exist before deployment for the trigger to be valid.
Steps to Create a Cloud Function Triggered by Cloud Storage
This PDE practice question tests your understanding of building and operationalizing data processing systems. 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.
Drag and drop the steps to create a Cloud Function triggered by Cloud Storage events into the correct order.
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
Step 1: Create a Cloud Storage bucket. Step 2: Write the Cloud Function code. Step 3: Deploy the Cloud Function with the appropriate event trigger. Step 4: Test the function by uploading a file to the bucket.
The correct sequence for creating a Cloud Function triggered by Cloud Storage events is: first ensure the bucket exists (create if needed), then write the function code, deploy the function with the appropriate event trigger (e.g., google.storage.object.finalize), and finally test by uploading a file. Common mistakes include deploying before creating the bucket, testing before deployment, or deploying without code.
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
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 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.
