Refer to the exhibit. A company is using an IAM role with the attached policy to deploy a SageMaker model. The data scientist can create training jobs and models, but when trying to create an endpoint, they receive an access denied error. What is the missing permission?

⚠ Common exam trap

Watch out — candidates often confuse the permissions needed for training jobs (which often require iam:PassRole) with those needed for endpoints, overlooking the VPC networking requirement that is specific to endpoint creation.

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

ec2:CreateNetworkInterface

When SageMaker creates an endpoint, it provisions a network interface in the customer's VPC to route traffic to the endpoint instances. The IAM role must have the ec2:CreateNetworkInterface permission to allow SageMaker to create this ENI; without it, the endpoint creation fails with an access denied error.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • cloudwatch:PutMetricData

    Why it's wrong here

    Not required for endpoint creation.

  • iam:PassRole

    Why it's wrong here

    PassRole is needed for the execution role, but the error is specifically on creating endpoint.

  • ec2:CreateNetworkInterface

    Why this is correct

    SageMaker creates an ENI in the VPC for the endpoint.

  • sagemaker:InvokeEndpoint

    Why it's wrong here

    InvokeEndpoint is for calling the endpoint, not creating.

  • kms:Decrypt

    Why it's wrong here

    Not needed unless using encrypted data.
