Full question →mediummultiple choiceObjective-mapped
A company operates multiple AWS accounts under AWS Organizations. The security team needs to record all management events (for example, creating Amazon EC2 instances, modifying security groups, and deleting Amazon S3 buckets) across all accounts. The logs must be delivered to a single Amazon S3 bucket that is encrypted with an AWS KMS key and protected from modification. Which AWS feature should the team enable to achieve this centralized logging requirement?
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
Best answer
AWS CloudTrail
AWS CloudTrail records API calls and can be configured as an organization trail to log activity across all accounts in AWS Organizations. It delivers log files to a specified S3 bucket, where encryption and immutability can be applied.
B
Distractor review
AWS Config
AWS Config records configuration changes and evaluates resource compliance against rules, but it does not capture every API call. It can use CloudTrail as a data source, but it is not the primary service for recording API events.
C
Distractor review
Amazon CloudWatch Logs
Amazon CloudWatch Logs is used to collect, monitor, and store log files from applications and AWS services. It does not natively record AWS API calls; CloudTrail can stream events to CloudWatch Logs, but CloudTrail itself is the service that captures the API events.
D
Distractor review
AWS Audit Manager
AWS Audit Manager helps assess your usage of AWS services against compliance requirements and generates audit reports. It relies on evidence collected from services like CloudTrail, but it does not directly record API calls.
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: AWS CloudTrail — AWS CloudTrail records AWS API calls and related events in your account. By enabling an organization trail in AWS Organizations, you can create a single trail that applies to all accounts in the organization, delivering log files to a single S3 bucket. The bucket can be encrypted with AWS KMS and can have S3 Object Lock enabled to prevent modification or deletion of log files. This centralized logging is essential for security analysis, compliance auditing, and operational troubleshooting.
