CCSP Practice Question: Refer to the exhibit
Exhibit
Refer to the exhibit. Error Log Entry: Timestamp: 2024-08-15T14:23:10Z User: [email protected] Action: PutObject Resource: s3://finance-reports/quarterly.xlsx Status: AccessDenied Source IP: 203.0.113.45 UserAgent: [ConsoleLogin] Additional: The user does not have permissions to write to this bucket.
Refer to the exhibit. A cloud administrator sees this error log from AWS CloudTrail. The user [email protected] is a member of the 'Analysts' group. Which of the following is the most likely cause of the AccessDenied error?
⚠ Common exam trap
ISC2 often tests the distinction between an implicit deny (missing Allow) and an explicit deny (Deny statement), and candidates mistakenly assume a bucket policy or encryption requirement is the cause when the error is simply a missing permission in the IAM policy.
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
✓
The IAM policy attached to the user or group does not include s3:PutObject for that bucket.
The AccessDenied error for an s3:PutObject operation indicates that the IAM policy attached to the user or group does not grant the necessary permissions. Since the user is a member of the 'Analysts' group, the most likely cause is that the group's IAM policy lacks an Allow effect for s3:PutObject on the target bucket. AWS IAM evaluates both identity-based and resource-based policies, and if no explicit Allow is present, the default implicit deny applies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The user is trying to access the bucket from a different AWS region.
Why it's wrong here
Cross-region access is allowed by default; region mismatch is not an issue.
- ✓
The IAM policy attached to the user or group does not include s3:PutObject for that bucket.
Why this is correct
Missing IAM permissions are a common cause of AccessDenied.
- ✗
The bucket policy explicitly denies access to the 'Analysts' group.
Why it's wrong here
A deny in bucket policy would also cause AccessDenied, but the log does not indicate a bucket policy denial.
- ✗
The bucket requires server-side encryption and the request did not include encryption headers.
Why it's wrong here
Encryption mismatch would produce a different error, not AccessDenied.
