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 DevOps engineer notices that the monthly compute cost is higher than expected for a Kubernetes Engine cluster. They want to identify which namespaces or workloads are contributing most to the cost. What should they do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable GKE Usage Metering and export to BigQuery.
Option D is correct because GKE Usage Metering exports detailed per-cluster resource consumption data (CPU, memory, storage, and network) to BigQuery, enabling cost attribution by namespace, label, or workload. This is the only option that directly provides granular cost breakdowns for Kubernetes resources, allowing the engineer to identify which namespaces or workloads drive compute costs.
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.
✗
Enable Logging for all containers and analyze logs.
Why it's wrong here
Logs do not provide cost information.
✗
Use Cloud Monitoring dashboards with Kubernetes metrics.
Why it's wrong here
Cloud Monitoring shows resource usage, not cost allocation.
✗
Add labels to nodes and use Cost Table reports.
Why it's wrong here
Labels on nodes apply to the whole node, not per workload.
✓
Enable GKE Usage Metering and export to BigQuery.
Why this is correct
GKE Usage Metering provides cost attribution by namespace and workload.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse monitoring metrics (CPU/memory usage) with cost data, or assume node labels and billing reports alone provide namespace-level granularity, missing that GKE Usage Metering is the specific tool designed for this exact use case.

Command / output trap
Cloud Monitoring shows resource usage, not cost allocation.
Detailed technical explanation
How to think about this question
GKE Usage Metering works by collecting resource usage data from the Kubernetes API server and writing it to a BigQuery dataset as tables like `gke_cluster_resource_usage` and `gke_cluster_cost_breakdown`. These tables include fields such as `namespace`, `workload`, `resource_type`, and `usage_quantity`, enabling SQL queries to sum costs per namespace. A real-world scenario is a multi-tenant cluster where one team's namespace uses GPU nodes; Usage Metering can isolate that cost, while node labels alone would not distinguish GPU vs. CPU usage within the same node pool.
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.
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
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.
