SAP-C02 Practice Question: Accelerate Workload Migration and Modernization

Exhibit

Refer to the exhibit.

```
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:PutObject",
      "Resource": "arn:aws:s3:::my-bucket/*",
      "Condition": {
        "IpAddress": {
          "aws:SourceIp": "203.0.113.0/24"
        }
      }
    }
  ]
}
```

Refer to the exhibit. A company is migrating an application to AWS and has attached the IAM policy shown to an IAM role. The application runs on an EC2 instance and needs to upload files to an S3 bucket. However, the uploads are failing with an access denied error. What is the most likely cause?

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 restricts access based on source IP, but the EC2 instance's public IP is not in the allowed range

The IAM policy explicitly allows s3:PutObject, so option A is incorrect. The resource ARN is correctly formatted as arn:aws:s3:::example-bucket/*, ruling out option B. The policy includes a condition (aws:SourceIp) that restricts access to the IP range 203.0.113.0/24. The EC2 instance's public IP may not fall within this range, causing the access denied error, making option C correct. Option D is incorrect because there is no indication of a bucket policy; the deny is due to the IAM policy's IP restriction.

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 IAM policy does not allow the s3:PutObject action
Why it's wrong here
Incorrect: The policy allows s3:PutObject.
✗
The IAM policy uses an incorrect resource ARN
Why it's wrong here
Incorrect: The resource ARN is correct for the bucket.
✓
The IAM policy restricts access based on source IP, but the EC2 instance's public IP is not in the allowed range
Why this is correct
Correct: The IP condition is likely blocking the instance.
✗
The S3 bucket policy denies access from the instance
Why it's wrong here
Incorrect: The exhibit shows an IAM policy, not a bucket policy.
