Quick Answer
The answer is AWS CloudTrail, as it is the service that records all API calls made within an AWS environment, including S3 bucket deletion events. When an SAP administrator needs to audit S3 bucket deletion API calls to investigate an accidental deletion of a bucket used for SAP backups, CloudTrail captures the exact user identity, source IP address, and timestamp of the delete action, providing a complete audit trail. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this concept tests your understanding of operational governance and security monitoring, often appearing in scenario-based questions where you must distinguish CloudTrail from services like AWS Config or Amazon Inspector. A common trap is confusing CloudTrail with S3 server access logs, but remember that CloudTrail focuses on management events like DeleteBucket, while server access logs track object-level requests. Memory tip: think of CloudTrail as the “call recorder” for every AWS API action—if it’s an API call, CloudTrail has the tape.
This PAS-C01 practice question tests your understanding of operations and maintenance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An SAP administrator needs to review API calls made by a user who accidentally deleted an S3 bucket used for SAP backups. Which AWS service provides a record of these API calls?
Amazon S3 server access logs
Why wrong: S3 access logs record requests to S3, but not all AWS API calls.
Amazon CloudWatch Logs
Why wrong: CloudWatch Logs stores application logs, not API calls.
AWS Config
Why wrong: Config tracks configuration changes, not API calls.
AWS CloudTrail
CloudTrail provides a record of API calls for governance and auditing.

Correct answer & explanation
AWS CloudTrail
AWS CloudTrail is the correct service because it records all API calls made to the AWS environment, including S3 bucket deletion events. When a user accidentally deletes an S3 bucket, CloudTrail captures the event details such as the user identity, source IP, and timestamp, enabling the SAP administrator to audit the action. This is essential for security analysis and operational troubleshooting in the context of SAP backups.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Amazon S3 server access logs
Why it's wrong here
S3 access logs record requests to S3, but not all AWS API calls.
Amazon CloudWatch Logs
Why it's wrong here
CloudWatch Logs stores application logs, not API calls.
AWS Config
Why it's wrong here
Config tracks configuration changes, not API calls.
AWS CloudTrail
Why this is correct
CloudTrail provides a record of API calls for governance and auditing.

Common exam traps
The trap here is that candidates often confuse Amazon S3 server access logs (which log object-level requests) with AWS CloudTrail (which logs management-plane API calls), leading them to select Option A when the question specifically asks about API calls that deleted the bucket itself.
Detailed technical explanation
AWS CloudTrail captures all S3 control-plane API calls (e.g., CreateBucket, DeleteBucket, PutBucketPolicy) via the S3 API, logging them as CloudTrail events in JSON format with fields like userIdentity (including ARN and access key), eventSource (s3.amazonaws.com), and requestParameters. These events are delivered to an S3 bucket or CloudWatch Logs, and the default retention is 90 days in the CloudTrail event history, but can be extended indefinitely by storing in S3. In a real-world SAP backup scenario, if the bucket was deleted by an IAM user or role, CloudTrail helps identify whether the action was accidental or malicious, and can be integrated with AWS Lambda for automated remediation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
