Full question →mediummultiple choiceObjective-mapped
A company has a strict security policy requiring that no Amazon S3 bucket or IAM role should be accessible to external AWS accounts unless explicitly approved. The security team needs a service that continuously analyzes resource-based policies and can generate findings when an S3 bucket policy allows access to a principal from outside the company's AWS Organization. Which AWS service should the team use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
AWS Config
AWS Config evaluates resource configurations against rules and can detect changes, but it does not specifically analyze resource-based policies to identify if they grant access to external principals. It is not the primary tool for this requirement.
B
Best answer
IAM Access Analyzer
IAM Access Analyzer continuously analyzes resource-based policies and generates findings when a resource is accessible from outside the AWS Organization. This matches the requirement of detecting unintended external access to S3 buckets and IAM roles.
C
Distractor review
AWS Trusted Advisor
AWS Trusted Advisor provides recommendations across cost, performance, security, and fault tolerance, including some checks for security group rules and IAM use. However, it does not continuously monitor resource-level policies for external access and does not generate findings for unintended sharing.
D
Distractor review
Amazon GuardDuty
Amazon GuardDuty is a threat detection service that monitors for malicious or unauthorized behavior, such as compromised instances or unusual API activity. It does not analyze resource-based policies for external access permissions.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
A company uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
FAQ
Questions learners often ask
What does this CLF-C02 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: IAM Access Analyzer — IAM Access Analyzer is designed to continuously analyze resource-based policies (such as S3 bucket policies and IAM role trust policies) and generate findings when a resource is accessible from outside the AWS Organization. AWS Config can evaluate resource configurations against rules but does not specifically focus on detecting external access. AWS Trusted Advisor provides best-practice recommendations but not continuous policy analysis for unintended sharing. Amazon GuardDuty is a threat detection service that monitors for malicious activity, not for resource policy analysis.
