Correct answer & explanation
✓
iam:PassRole
The error occurs because the IAM policy does not include the `iam:PassRole` permission. When creating a SageMaker endpoint, the service must assume an IAM role to access resources (e.g., S3 buckets, CloudWatch). The `iam:PassRole` permission allows the user to pass that role to SageMaker. The other actions listed are either for inference (`InvokeEndpoint`), listing endpoints (`ListEndpoints`), or updating endpoints (`UpdateEndpoint`), which are not relevant to the creation process. Therefore, the missing permission is `iam:PassRole` (Option A).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
iam:PassRole
Why this is correct
SageMaker needs iam:PassRole to assume a role for creating endpoints.
- ✗
sagemaker:ListEndpoints
Why it's wrong here
ListEndpoints is for listing.
- ✗
sagemaker:InvokeEndpoint
Why it's wrong here
InvokeEndpoint is for inference, not creation.
- ✗
sagemaker:UpdateEndpoint
Why it's wrong here
UpdateEndpoint is for updating endpoints.
