PCDOE Optimizing performance and cost Practice Question
A company is using Google Cloud and wants to monitor and control costs. Which TWO actions should they take? (Choose two.)
⚠ Common exam trap
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.
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 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.
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.
- ✓
Use labels to categorize resources and track costs by team.
Why this is correct
Labels enable cost allocation and reporting, helping control costs.
- ✗
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.
