The correct answer is that the action will be denied because the Deny statement explicitly blocks CreateEndpointConfig when the subnet does not match. This occurs because IAM policy evaluation logic gives Deny statements absolute precedence over Allow statements, so even if another policy permits the action, the explicit Deny with a condition key for the subnet mismatch overrides everything. On the AWS Certified Machine Learning Engineer Associate MLA-C01 exam, this tests your understanding of how to use IAM policy conditions to restrict SageMaker endpoint creation to a specific VPC subnet, a common security requirement for controlling network traffic in ML deployments. A frequent trap is assuming an Allow statement alone can override a Deny, but remember that Deny is always the final decision in IAM. Memory tip: think of Deny as a "veto" — no matter how many Allow votes you have, one Deny kills the action.
MLA-C01 Deployment and Orchestration of ML Workflows Practice Question
This MLA-C01 practice question tests your understanding of deployment and orchestration of ml workflows. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Refer to the exhibit. An AWS IAM policy is attached to a role used by a CI/CD pipeline to deploy SageMaker endpoints. The pipeline attempts to create an endpoint configuration with a VPC subnet that is not subnet-0123456789abcdef0. What will happen when the pipeline tries to create the endpoint configuration?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The action will be denied because the Deny statement explicitly blocks CreateEndpointConfig when the subnet does not match.
Option A is correct because the IAM policy includes a Deny statement with a condition that explicitly blocks the `CreateEndpointConfig` action when the subnet specified in the request does not match `subnet-0123456789abcdef0`. Since the pipeline is attempting to create an endpoint configuration with a different subnet, the Deny statement overrides any Allow statements, resulting in the action being denied.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 action will be denied because the Deny statement explicitly blocks CreateEndpointConfig when the subnet does not match.
Why this is correct
An explicit Deny overrides any Allow, and the condition is not met.
Related concept
Read the scenario before looking for a memorised answer.
✗
The action will be allowed because the CreateEndpoint statement allows all endpoints.
Why it's wrong here
The Deny on CreateEndpointConfig is separate and will block this action.
✗
The action will be allowed only if the endpoint configuration uses a VPC with multiple subnets.
Why it's wrong here
The condition requires the exact subnet, not multiple.
✗
The action will be allowed because the policy lacks a Deny on the subnet condition for the endpoint resource.
Why it's wrong here
The Deny applies to CreateEndpointConfig regardless of the endpoint resource.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume an Allow statement for `CreateEndpoint` would permit the action, but they overlook that an explicit Deny on the `CreateEndpointConfig` action with a subnet condition takes precedence, causing the request to fail.
Detailed technical explanation
How to think about this question
In AWS IAM, explicit Deny statements always override any Allow statements, making them a powerful tool for enforcing strict compliance requirements. The condition key `sagemaker:VpcSubnets` is used to restrict which subnets can be used when creating SageMaker endpoint configurations, and if the condition does not match, the Deny is triggered. This pattern is common in regulated environments where data must remain within specific VPC subnets for security or compliance reasons.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
