CV0-004 Operations and Support Practice Question
A cloud engineer wants to view a dashboard showing cost breakdown by department. Which tool provides pre-built billing dashboards?
⚠ Common exam trap
CV0-004 often tests whether candidates confuse monitoring tools like CloudWatch with billing tools, or pick Trusted Advisor because it sounds like it would surface cost insights.
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
✓
AWS Cost Explorer
AWS Cost Explorer includes pre-built reports and dashboards that break down costs by dimensions such as service, linked account, and tag, which can represent departments. It is the native AWS tool for visualizing and analyzing billing data, including cost by department when tags are used.
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 CloudWatch
Why it's wrong here
CloudWatch collects operational metrics, logs and alarms for running resources; it holds no billing line items, so departmental cost breakdowns cannot be charted. It would be correct for monitoring CPU, latency or triggering alarms on performance thresholds.
- ✓
AWS Cost Explorer
Why this is correct
AWS Cost Explorer provides pre-built dashboards that visualise cost and usage data, including breakdowns by dimension such as department when costs are tagged accordingly. This directly satisfies the requirement for an existing billing dashboard, unlike raw billing reports or custom-built tooling that would need manual configuration.
- ✗
AWS Trusted Advisor
Why it's wrong here
AWS Trusted Advisor inspects account configuration against best-practise checks — cost optimisation flags idle or underused resources, not departmental spend breakdowns. It is tempting because its cost optimisation category does address billing, but it reports individual saving opportunities rather than the aggregated, per-department dashboard the engineer requires; that is Cost Explorer's function.
- ✗
AWS Config
Why it's wrong here
AWS Config records resource configuration changes and evaluates compliance rules, exposing no cost or billing data, so no departmental spend dashboard exists. It would be correct for tracking configuration drift or auditing resource state against policies.
