- A
Compute Engine with a startup script
Why wrong: Compute Engine requires managing VMs and does not automatically trigger on Cloud Storage events. Not cost-effective for small event-driven tasks.
- B
App Engine Standard
Why wrong: App Engine Standard does not have native Cloud Storage event triggers; you would need to poll Cloud Storage, which is inefficient.
- C
Cloud Run jobs
Why wrong: Cloud Run jobs are for batch processing, not event-driven triggers. They are not natively triggered by Cloud Storage events.
- D
Cloud Functions (Gen 2)
Gen 2 Cloud Functions supports event triggers from Cloud Storage and has a maximum timeout of 60 minutes, fitting the 10-minute requirement. It is serverless and cost-effective.

Google ACE Planning and Configuring a Cloud Solution Practice Question
This ACE practice question tests your understanding of planning and configuring a cloud solution. 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 startup wants to run a small, event-driven application that processes files uploaded to Cloud Storage. The function should be triggered by object finalize events and should have a maximum execution time of 10 minutes. Which compute option is most cost-effective and easy to manage?
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
✓
Cloud Functions (Gen 2)
Cloud Functions (Gen 2) can be triggered by Cloud Storage events and supports longer timeouts (up to 60 minutes). It is serverless and cost-effective for event-driven workloads. Cloud Run also works but requires running a container; Cloud Functions is simpler for single-purpose functions.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
