ACE Practice Question: A batch data processing job runs nightly for 4…
This ACE practice question tests your understanding of a batch data processing job runs nightly for 4…. 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 batch data processing job runs nightly for 4 hours and can tolerate interruption because it saves progress checkpoints every 15 minutes. Which VM option offers the greatest cost reduction?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Shielded VM
Shielded VMs add security features (Secure Boot, vTPM) but don't reduce the base VM cost.
B
Distractor review
Custom machine type VM with reduced memory
Custom machine types optimize resource allocation but don't provide the deep discounts of Spot VMs.
C
Best answer
Spot VM
Spot VMs are available at up to 91% discount and are ideal for batch workloads that tolerate interruption and implement checkpointing.
D
Distractor review
Sole-tenant node VM
Sole-tenant nodes are used for compliance and licensing isolation — they are more expensive than standard VMs, not cheaper.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this ACE question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Spot VM — Spot VMs (formerly Preemptible VMs) offer discounts of up to 91% compared to standard VMs. They can be preempted with a 30-second notice, making them ideal for fault-tolerant workloads that checkpoint progress. Custom machine types optimize resource fit but don't inherently reduce cost as dramatically.
What should I do if I get this ACE question wrong?
Identify which ACE exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
