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.
Which GCP tool provides recommendations for rightsizing Compute Engine VMs?
Cloud Console Cost Table.
Why wrong: Cost Table shows current costs, not recommendations.
Cloud Monitoring.
Why wrong: Cloud Monitoring provides metrics and alerts, not cost optimization recommendations.
Cloud Billing Reports.
Why wrong: Cloud Billing Reports show historical cost data, not recommendations.
Recommender.
Recommender provides rightsizing and other cost optimization recommendations.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Recommender.
The Recommender tool in GCP uses machine learning to analyze historical usage patterns and provides actionable recommendations, including rightsizing suggestions for Compute Engine VMs. It identifies underutilized VMs and suggests optimal machine types to reduce costs without compromising performance, making it the correct choice for this task.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Cloud Console Cost Table.
Why it's wrong here
Cost Table shows current costs, not recommendations.
Cloud Monitoring.
Why it's wrong here
Cloud Monitoring provides metrics and alerts, not cost optimization recommendations.
Cloud Billing Reports.
Why it's wrong here
Cloud Billing Reports show historical cost data, not recommendations.
Recommender.
Why this is correct
Recommender provides rightsizing and other cost optimization recommendations.
Related concept
Read the scenario before looking for a memorised answer.
Common exam traps
The trap here is that candidates often confuse Cloud Monitoring's alerting capabilities with proactive recommendations, assuming that monitoring data alone provides rightsizing suggestions, but Recommender is the dedicated tool for that purpose.
Trap categories for this question
Command / output trap
Cost Table shows current costs, not recommendations.
Detailed technical explanation
The Recommender uses the Compute Engine VM Rightsizing Recommender, which analyzes CPU, memory, and network utilization over a 14-day period (configurable) and applies a cost-benefit analysis to suggest machine type changes. It leverages the same ML models used in Google's internal optimization, and recommendations are accessible via the gcloud recommender commands or REST API, allowing integration into automated workflows. A subtle behavior is that it excludes VMs with less than 7 days of data or those with sustained usage patterns that might skew recommendations.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
