- A
Enable AWS Config to perform the cost optimization and underutilization checks.
Why wrong: 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.
- B
Upgrade to a Developer Support plan.
Why wrong: 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.
- C
Upgrade to a Business or Enterprise Support plan.
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.
- D
No action is needed; the full set of Trusted Advisor checks is already available for all AWS Support plans.
Why wrong: 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.
Quick Answer
The answer is to upgrade to a Business or Enterprise Support plan. AWS Trusted Advisor full checks access is locked behind these higher-tier plans, meaning only Business and Enterprise support subscribers see the complete library of recommendations, including cost optimization checks for idle load balancers and underutilized EC2 instances. Basic and Developer Support plans restrict you to a limited subset of core checks, like S3 bucket permissions and service limits, which is why the operations team sees only those. On the AWS Certified Cloud Practitioner CLF-C02 exam, this distinction tests your understanding of how support tiers directly impact operational tooling—a common trap is assuming all Trusted Advisor checks are free or that upgrading to Developer Support will suffice. Remember the memory tip: “Business unlocks the full business of Trusted Advisor,” meaning you need Business or Enterprise to get every check.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 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?
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.

Why this is correct

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that 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.
Detailed technical explanation
How to think about this question
AWS Trusted Advisor uses a set of automated checks that evaluate your AWS environment against best practices. The checks are categorized into five pillars: cost optimization, performance, security, fault tolerance, and service limits. Under the hood, the full check library is gated by the support plan tier via IAM policies and service-level entitlements; even if you enable AWS Config, it does not grant access to the Trusted Advisor cost optimization checks because those checks are a distinct feature of the support plan. In a real-world scenario, a company on a Basic plan might see only 7 core checks, while a Business plan unlocks over 100 checks, including those for idle resources and underutilized EC2 instances.
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.
