{
"Policy": {
"PolicyName": "S3ReadOnlyAccess",
"PolicyId": "ANPAY6TVEXAMPLE",
"Arn": "arn:aws:iam::123456789012:policy/S3ReadOnlyAccess",
"Path": "/",
"DefaultVersionId": "v3",

}
}
```An IAM policy named S3ReadOnlyAccess has DefaultVersionId v3. What does this indicate?
⚠ Common exam trap
ISC2 often tests the misconception that DefaultVersionId indicates the total number of versions or that a policy with a non-v1 default is somehow broken or unattachable, when in fact it simply shows which version is active.
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 policy is currently using version v3 as the default.
The DefaultVersionId of an IAM policy indicates which version is currently active and enforced when the policy is attached to an IAM user, group, or role. Since the policy is named S3ReadOnlyAccess and has DefaultVersionId v3, version v3 is the default and is being used for access control decisions. This is the standard behavior for IAM policies in AWS, where you can have multiple versions but only one is designated as the default.
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 policy is newly created.
Why it's wrong here
CreateDate is earlier than UpdateDate.
- ✓
The policy is currently using version v3 as the default.
Why this is correct
DefaultVersionId indicates the active version.
- ✗
The policy has three custom versions.
Why it's wrong here
DefaultVersionId shows the active version, not the count.
- ✗
The policy cannot be attached to any entity.
Why it's wrong here
IsAttachable is true, so it can be attached.
