Quick Answer
The answer is ListObjects. This is the correct CloudTrail event name because the ListObjects API call is the specific AWS S3 operation that retrieves a list of all objects within a bucket, and CloudTrail logs every API action under its exact operation name. When an investigator sees a ListObjects event in the logs, it directly corresponds to a successful attempt to enumerate the bucket’s contents, making it a critical indicator for forensic analysis. On the Computer Hacking Forensic Investigator CHFI exam, this question tests your ability to map AWS API operations to their CloudTrail event names, a common scenario in cloud forensics where you must distinguish between data access events like GetObject (reading a file) and listing events like ListObjects. A frequent trap is confusing ListObjects with GetObject or HeadObject, but remember that listing is about seeing what exists, not retrieving the data itself. For a quick memory tip, think “ListObjects = Listing the contents,” and note that the event name is always the exact API call in PascalCase.
This CHFI practice question tests your understanding of application, email and cloud forensics. 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 cloud forensic investigator is examining AWS CloudTrail logs for signs of unauthorized access to an S3 bucket. Which of the following CloudTrail event names would indicate a successful attempt to list the objects in the bucket?
GetObject
Why wrong: GetObject retrieves a specific object.
PutObject
Why wrong: PutObject is for uploading objects.
DeleteObject
Why wrong: DeleteObject deletes an object.
ListObjects
ListObjects is the API call to list objects in a bucket.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
ListObjects
The ListObjects operation lists the objects in an S3 bucket; the CloudTrail event name is 'ListObjects'.
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.
GetObject
Why it's wrong here
GetObject retrieves a specific object.
PutObject
Why it's wrong here
PutObject is for uploading objects.
DeleteObject
Why it's wrong here
DeleteObject deletes an object.
ListObjects
Why this is correct
ListObjects is the API call to list objects in a bucket.

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
