CV0-004 Operations and Support Practice Question
A company uses AWS and wants to analyze cost trends and identify the top services contributing to monthly spending. Which AWS tool provides a pre-built dashboard for this purpose?
⚠ Common exam trap
CV0-004 often tests the distinction between cost visibility tools (Cost Explorer, CUR) and cost governance tools (Budgets, Trusted Advisor), so candidates pick Budgets thinking 'cost management' means alerts rather than analysis.

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
✓
AWS Cost Explorer
AWS Cost Explorer is the native cost analysis tool that includes pre-built reports and dashboards for visualizing spend over time, forecasting, and identifying top cost-driving services by filtering on dimensions like service, linked account, or tag. It aggregates Cost and Usage Report data and presents it through a console UI with default views such as 'Cost by Service' and 'Monthly Costs by Linked Account'. This directly matches the requirement for a pre-built dashboard to analyze trends and top contributing services.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Trusted Advisor
Why it's wrong here
AWS Trusted Advisor inspects your account against best-practise checks for cost optimisation, security, fault tolerance and service limits, but it does not aggregate historical spend by service or render cost-trend dashboards. It is tempting because its cost-optimisation category flags idle resources; that suits reducing waste, whereas analysing monthly spending trends requires AWS Cost Explorer's pre-built reports.
- ✓
AWS Cost Explorer
Why this is correct
AWS Cost Explorer supplies a pre-built dashboard with cost trend graphs and service-level breakdowns, directly satisfying the requirement to analyse monthly spending and identify top contributing services. It visualises up to 12 months of historical data, whereas Budgets only alerts on thresholds and Cost and Usage Reports deliver raw data.
- ✗
AWS Compute Optimizer
Why it's wrong here
AWS Compute Optimizer analyses resource configuration and utilisation metrics to recommend right-sizing for compute services; it produces no cost-trend dashboard and cannot rank services by monthly spend. It is tempting because it does address cost reduction, but it would be the correct choice when the requirement is identifying over-provisioned EC2 instances rather than analysing spending trends.
- ✗
AWS Budgets
Why it's wrong here
AWS Budgets tracks spend against thresholds you define and raises alerts when usage or forecast crosses them; it presents no pre-built cost-trend dashboard nor service-level breakdown. It is tempting because it genuinely addresses cost governance, and would be the right choice when the requirement is notifying teams that a budget limit is approaching or breached.
