The answer is setting up budget alerts and using labels to categorize resources. Budget alerts are a fundamental cost control mechanism in Google Cloud, allowing you to define a spending threshold and receive notifications when actual or forecasted costs exceed specified percentages, such as 50%, 90%, or 100%, enabling proactive intervention before costs escalate. Labels, meanwhile, are key-value pairs attached to resources that enable granular cost tracking in billing reports, allowing you to allocate spending by team, project, or environment, which directly supports accountability and cost attribution. On the Google Professional Cloud DevOps Engineer exam, this question tests your understanding of operational cost governance—a core DevOps responsibility—and often appears alongside distractors like disabling all services or deleting unused projects, which are reactive rather than proactive. A common trap is confusing labels with tags or assuming budget alerts alone are sufficient without the categorization that labels provide. Memory tip: think “Alert to halt, label to sort”—budget alerts stop the bleeding, labels show where the wound is.
PCDOE Managing Google Cloud costs Practice Question
This PCDOE practice question tests your understanding of managing google cloud costs. 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 company is using Google Cloud and wants to monitor and control costs. Which TWO actions should they take? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set up budget alerts to notify when spending exceeds thresholds.
Setting up budget alerts (option A) is a core cost control action because it allows you to define a budget amount and receive notifications when actual or forecasted spending exceeds a specified threshold (e.g., 50%, 90%, 100%). This enables proactive intervention before costs spiral out of control. Using labels (option B) to categorize resources (e.g., by team, project, or environment) allows you to track and allocate costs accurately in billing reports, making it easier to identify cost drivers and enforce accountability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Set up budget alerts to notify when spending exceeds thresholds.
Why this is correct
Budget alerts help monitor and control costs by providing notifications.
Related concept
Read the scenario before looking for a memorised answer.
✓
Use labels to categorize resources and track costs by team.
Why this is correct
Labels enable cost allocation and reporting, helping control costs.
Related concept
Read the scenario before looking for a memorised answer.
✗
Disable all unnecessary APIs at the organization level.
Why it's wrong here
Disabling APIs globally may affect other projects; better to manage per project.
✗
Export billing data to BigQuery for detailed analysis.
Why it's wrong here
Exporting to BigQuery is for analysis, not direct cost control.
✗
Grant billing account access to all project owners.
Why it's wrong here
Granting billing access to all owners increases risk of accidental spending.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between cost monitoring (e.g., exporting to BigQuery) and cost control (e.g., budget alerts and labels), so candidates mistakenly select options that only provide visibility rather than active enforcement or categorization.
Detailed technical explanation
How to think about this question
Budget alerts in Google Cloud are implemented through the Cloud Billing API and can trigger Pub/Sub notifications or email alerts based on budget amount and threshold rules. Labels are key-value pairs attached to resources (e.g., 'cost-center:engineering') and are propagated to billing export tables, enabling cost breakdowns by label in tools like BigQuery or the Cloud Billing Reports UI. A common real-world scenario is a multi-team organization where labels allow each team to see only their own costs in a shared billing account, while budget alerts prevent surprise bills from runaway compute instances.

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.

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.
