PAS-C01 Technology Practice Question
Exhibit
Refer to the exhibit.
Exhibit:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3:PutObject",
"Resource": "arn:aws:s3:::sap-backup-bucket/*",
"Condition": {
"StringEquals": {
"s3:x-amz-server-side-encryption": "AES256"
}
}
},
{
"Effect": "Deny",
"Action": "s3:PutObject",
"Resource": "arn:aws:s3:::sap-backup-bucket/*",
"Condition": {
"StringNotEquals": {
"s3:x-amz-server-side-encryption": "AES256"
}
}
}
]
}Refer to the exhibit. An IAM policy is attached to an EC2 instance role used by SAP HANA backup scripts. The backup script attempts to upload a file to the S3 bucket without specifying server-side encryption. What will happen?
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 upload fails because of the Deny statement.
The first statement allows PutObject only if encryption is AES256. The second statement denies PutObject if encryption is not AES256. Since the request does not specify encryption, it does not match the condition in the Allow statement (so not allowed) and it matches the Deny statement because encryption is not AES256 (StringNotEquals). Therefore, the request is denied.
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 upload fails because there is no Allow statement without condition.
Why it's wrong here
The Allow statement requires encryption, so it does not apply.
- ✗
The upload succeeds because there is an Allow statement.
Why it's wrong here
The Allow has a condition that is not met, so it does not apply.
- ✓
The upload fails because of the Deny statement.
Why this is correct
The Deny statement explicitly denies PutObject when encryption is not AES256.
- ✗
The upload succeeds because the Deny condition does not match.
Why it's wrong here
The Deny condition matches because encryption is not AES256.
