Google PCA Practice Question: Analysing and Optimising Technical and Business Processes

Your organization is adopting Google Cloud and wants to establish a cost governance framework. You need to implement mechanisms that provide visibility into spending and allow proactive control over costs. (Choose two.)

⚠ Common exam trap

The trap here is equating cost optimization techniques like committed use discounts with governance, which actually requires visibility and alerting.

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 in Cloud Billing to notify stakeholders when spending exceeds a defined threshold.

Cost governance requires both visibility and proactive control. Exporting billing data to BigQuery with Looker Studio dashboards provides deep visibility into spending patterns, while budget alerts notify stakeholders when thresholds are breached. Together, they enable analysis and timely intervention. The other options are either optimization tactics, overly broad permissions, or planning tools that lack ongoing monitoring.

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 in Cloud Billing to notify stakeholders when spending exceeds a defined threshold.
Why this is correct
Budget alerts provide proactive notifications when costs approach or exceed predefined limits. They do not stop spending, but they enable timely action. This is a core cost governance mechanism that increases awareness and allows teams to react before costs escalate. It complements detailed analysis by providing early warnings.
✗
Assign the Billing Account Administrator role to all project owners to ensure they can view and manage costs.
Why it's wrong here
Granting Billing Account Administrator to all project owners gives broad permissions to manage billing, which may violate least privilege. It also does not provide visibility or proactive control by itself; it only grants access. Cost governance relies on tools like budgets and billing export, not on wide role assignments.
✗
Use the Pricing Calculator to estimate costs before deploying new resources.
Why it's wrong here
The Pricing Calculator is useful for estimating future costs during planning, but it does not provide ongoing visibility into actual spending or proactive control. It is a static estimation tool, not a monitoring or alerting mechanism. For governance, you need continuous tracking and alerts based on real usage.
✗
Enable committed use discounts for all Compute Engine instances to reduce the effective cost per hour.
Why it's wrong here
Committed use discounts reduce prices for predictable workloads, but they do not provide visibility or proactive control over spending. They are a cost optimization tactic, not a governance mechanism. Without analysis and alerts, you might commit to resources you do not need. This option addresses cost reduction, not governance.
✓
Export billing data to BigQuery and create custom dashboards in Looker Studio to analyze cost trends by project and label.
Why this is correct
Exporting billing data to BigQuery enables detailed analysis and custom reporting. Looker Studio can visualize this data, helping you identify cost drivers and trends. This provides the visibility needed for cost governance and supports informed decision-making. It is a recommended practice for understanding and optimizing cloud spend.
