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 role can use the key to encrypt and decrypt, regardless of its IAM policy.
A KMS grant allows the grantee to perform the specified operations (in this case, Encrypt and Decrypt) on the KMS key without needing additional permissions in the IAM policy. The grant provides these permissions directly to the grantee, independent of IAM policies. Option B is incorrect because the grant's permissions are effective regardless of the IAM policy; they do not require IAM policy to also allow the operations. Option C is incorrect because the grant does not include permission to delete the key; deletion requires separate IAM permissions. Option D is incorrect because creating new grants is a separate permission (CreateGrant) that is not included in a grant that only allows Encrypt and Decrypt.
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 role can use the key to encrypt and decrypt, regardless of its IAM policy.
Why this is correct
The grant explicitly allows Encrypt and Decrypt operations, and grants bypass IAM policy restrictions.
- ✗
The role can use the key to encrypt and decrypt, but only if its IAM policy also allows it.
Why it's wrong here
This is incorrect because grants are independent of IAM policies; the role can use the key even if its IAM policy does not allow it.
- ✗
The role can delete the KMS key.
Why it's wrong here
The grant does not include the kms:DeleteKey permission.
- ✗
The role can create new grants for this key.
Why it's wrong here
The grant does not include the kms:CreateGrant permission.
