- A
Use IAM conditions to restrict instance creation.
Why wrong: IAM conditions can restrict instance creation based on attributes such as machine type or region, but they cannot enforce a numeric limit on the total number of instances. This method does not control maximum count.
- B
Enable preemptible VMs.
Why wrong: Enabling preemptible VMs reduces cost but does not limit the maximum number of instances that can be created.
- C
Create budget alerts with a threshold at 80% of budget.
Why wrong: Budget alerts notify when spending reaches a threshold but do not prevent instance creation.
- D
Set resource quotas for compute instances.
Resource quotas set a hard limit on the number of compute instances that can be created in a project, effectively controlling the maximum count.
- E
Apply committed use discounts.
Why wrong: Committed use discounts provide cost savings for consistent usage but do not limit the number of instances.
PCDOE Resource Quotas Practice Question
This PCDOE practice question tests your understanding of managing google cloud costs. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: resource Quotas. 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 company wants to control costs by limiting the maximum number of Compute Engine instances a project can create. Which TWO methods can achieve this? (Choose two.)
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
Set resource quotas for compute instances.
Resource quotas are the only method among the options that can limit the maximum number of instances by setting a hard cap on instance count. IAM conditions can restrict instance creation based on attributes like machine type or region but cannot enforce a numeric limit on the number of instances. Therefore, only option D is correct.
Key principle: Resource Quotas

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
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember

TExam Day Tips
- 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
Resource Quotas
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.
