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.

Exhibit

{
  "budgetName": "projects/my-project/budgets/my-budget",
  "costAmount": 1500.00,
  "budgetAmount": 1000.00,
  "alertThresholdExceeded": 1.0,
  "budgetFilter": {
    "projects": ["projects/dev-123"],
    "creditTypesTreatment": "INCLUDE_ALL_CREDITS"
  }
}

Refer to the exhibit. A budget alert has fired for project dev-123 indicating that the cost has exceeded the budget of $1000. What should the team do next to investigate the cost overrun?

Exhibit

{
  "budgetName": "projects/my-project/budgets/my-budget",
  "costAmount": 1500.00,
  "budgetAmount": 1000.00,
  "alertThresholdExceeded": 1.0,
  "budgetFilter": {
    "projects": ["projects/dev-123"],
    "creditTypesTreatment": "INCLUDE_ALL_CREDITS"
  }
}

A
Disable all APIs in project dev-123 immediately.
Why wrong: Disabling APIs could disrupt services; investigation should come first.
B
Open a BigQuery query on the billing export table, filtering by project 'dev-123' and service.
BigQuery billing exports provide detailed cost data for root cause analysis.
C
Set up a Cloud Function to automatically shut down resources when the budget is exceeded.
Why wrong: Automated shutdown is a remediation step, not an investigation step.
D
View the billing account's cost table in the Cloud Console.
Why wrong: The console shows aggregated costs but lacks granular breakdown to pinpoint the cause.
E
Create a new budget with a lower threshold to get alerted earlier.
Why wrong: This does not help investigate; it's a reactive measure.

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

✓

Open a BigQuery query on the billing export table, filtering by project 'dev-123' and service.

The most effective first step is to query the billing export data in BigQuery, which provides detailed cost breakdowns by project, service, and labels. Option B is the recommended approach for granular analysis. Viewing the billing account page (A) gives a high-level view but not the necessary detail. Creating a new budget (C) does not address the root cause. Disabling APIs (D) is too drastic without understanding the cause. Setting up automatic shutdown (E) is a reaction that should follow investigation.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation

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.

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.
