Question 751 of 988
CLF-C02 Billing, Pricing, and Support Practice Question
A company has an AWS Basic Support plan. The operations team wants to use AWS Trusted Advisor to receive recommendations for cost optimization, such as identifying idle load balancers and underutilized Amazon EC2 instances. They log into the AWS Management Console and navigate to Trusted Advisor, but they only see a limited set of checks, such as S3 bucket permissions and service limits. Which action should the team take to access the complete library of Trusted Advisor checks, including the cost optimization recommendations?
⚠ Common exam trap
Candidates often assume AWS Config can perform cost optimization checks similar to Trusted Advisor, or that upgrading to a Developer plan is sufficient, when in fact only Business or Enterprise plans unlock the full Trusted Advisor check library.
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
✓
Upgrade to a Business or Enterprise Support plan.
AWS Trusted Advisor provides a full set of checks, including cost optimization recommendations (e.g., idle load balancers, underutilized EC2 instances), only to customers with a Business or Enterprise Support plan. The Basic Support plan restricts Trusted Advisor to a limited subset of checks, such as S3 bucket permissions and service limits. Therefore, upgrading to a Business or Enterprise Support plan is required to access the complete library of checks.
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 AWS Config to perform the cost optimization and underutilization checks.
Why it's wrong here
AWS Config is a service that evaluates resource configurations against rules and can help with compliance and security, but it is not the same as Trusted Advisor. It does not provide the same predefined cost optimization checks like idle load balancers or underutilized EC2 instances. Enabling Config does not unlock additional Trusted Advisor checks.
When this WOULD be correct
If the question asked which service to use to evaluate resource configurations against best practices and automate remediation (e.g., detecting non-compliant security groups), enabling AWS Config would be correct.
- ✗
Upgrade to a Developer Support plan.
Why it's wrong here
The Developer Support plan, like the Basic plan, provides only the core set of Trusted Advisor checks. It does not include the full set of checks related to cost optimization, performance, or fault tolerance. Upgrading to Developer does not resolve the limitation.
When this WOULD be correct
If the question asked which support plan provides access to AWS Support API and a 12-hour response time for impaired systems, then upgrading to Developer Support would be correct.
- ✓
Upgrade to a Business or Enterprise Support plan.
Why this is correct
The full library of Trusted Advisor checks, which includes cost optimization recommendations (e.g., idle load balancers, underutilized EC2 instances), is available only to customers with a Business or Enterprise Support plan. These plans provide access to all checks across security, cost optimization, performance, and fault tolerance.
- ✗
No action is needed; the full set of Trusted Advisor checks is already available for all AWS Support plans.
Why it's wrong here
This statement is incorrect. While a core set of checks is available to all support plans (Basic, Developer), the full set of checks, including advanced cost optimization and performance recommendations, is restricted to Business and Enterprise Support plans. Simply navigating to the Trusted Advisor console does not unlock additional checks without upgrading.
When this WOULD be correct
If the question stated that the company already has a Business or Enterprise Support plan, or if the scenario involved only the checks available in Basic Support (e.g., S3 bucket permissions and service limits), then no action would be needed.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.

✗Enable AWS Config to perform the cost optimization and underutilization checks.Wrong answer — click to see why▾
Why this is wrong here
AWS Config is a service for resource inventory and configuration history, not for providing Trusted Advisor checks. Trusted Advisor's full set of checks, including cost optimization, requires a Business or Enterprise Support plan.
★ When this WOULD be the correct answer
If the question asked which service to use to evaluate resource configurations against best practices and automate remediation (e.g., detecting non-compliant security groups), enabling AWS Config would be correct.
Why candidates choose this
Candidates may confuse AWS Config's compliance checks with Trusted Advisor's recommendations, assuming both offer similar cost optimization features.
✗Upgrade to a Developer Support plan.Wrong answer — click to see why▾
Why this is wrong here
The Developer Support plan does not include the full set of Trusted Advisor checks; only Business and Enterprise Support plans provide access to all checks, including cost optimization recommendations.
★ When this WOULD be the correct answer
If the question asked which support plan provides access to AWS Support API and a 12-hour response time for impaired systems, then upgrading to Developer Support would be correct.
Why candidates choose this
Candidates may confuse the Developer plan as a higher tier than Basic, but they don't realize that the full Trusted Advisor checks require Business or Enterprise level.
✗No action is needed; the full set of Trusted Advisor checks is already available for all AWS Support plans.Wrong answer — click to see why▾
Why this is wrong here
The AWS Basic Support plan only provides a limited set of Trusted Advisor checks (e.g., S3 bucket permissions and service limits). Cost optimization checks like idle load balancers and underutilized EC2 instances require a Business or Enterprise Support plan.
★ When this WOULD be the correct answer
If the question stated that the company already has a Business or Enterprise Support plan, or if the scenario involved only the checks available in Basic Support (e.g., S3 bucket permissions and service limits), then no action would be needed.
Why candidates choose this
Candidates may assume that all Trusted Advisor checks are free and available to all support plans, not realizing that cost optimization and advanced checks are restricted to higher-tier plans.
