- A
Cloud Functions with background trigger
Why wrong: Cloud Functions has a maximum timeout (typically 9 minutes for HTTP functions, 60 minutes for background functions) and is not designed for long-running batch processes.
- B
Compute Engine with preemptible VMs
Preemptible VMs are ideal for fault-tolerant, interruptible batch workloads because they provide significant cost savings (up to 80% discount) and can be restarted if preempted.
- C
Google Kubernetes Engine with standard nodes
Why wrong: GKE with standard nodes is more expensive than preemptible VMs and adds complexity of container orchestration for a simple batch job.
- D
Cloud Run with manual scaling
Why wrong: Cloud Run has a request timeout of 60 minutes (up to 60 minutes for async) and is not optimized for long-running batch jobs; also cost is per request, not per compute time for sustained use.
Cloud Digital Leader Google Cloud Products and Services Practice Question
This GCDL practice question tests your understanding of google cloud products and services. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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.
An organization needs to run a batch process every night that analyzes terabytes of data from Cloud Storage and writes results back to BigQuery. The job is not time-sensitive and can be preempted. Which compute approach is most cost-effective?
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
Compute Engine with preemptible VMs
Preemptible VMs on Compute Engine offer the lowest cost for fault-tolerant batch workloads because they are up to 80% cheaper than regular VMs but can be terminated at any time. Cloud Run has a request timeout limit and is not ideal for long-running batch jobs. GKE with preemptible nodes is also cost-effective but requires Kubernetes expertise and is more complex than simply using preemptible VMs. Cloud Functions has a timeout limit.
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.
