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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A financial services company deploys a fraud detection model on a SageMaker real-time endpoint. The inference logic includes a pre-processing step that requires access to a DynamoDB table for user metadata. The model container is a custom Docker image. How should the team grant the endpoint access to DynamoDB?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an IAM role with DynamoDB read access and assign it to the SageMaker endpoint as the execution role
Option C is correct because SageMaker endpoints require an IAM execution role to be assigned at creation time. This role defines the permissions the endpoint's container has when making AWS API calls, such as reading from DynamoDB. By attaching a policy with DynamoDB read access to this execution role, the endpoint securely obtains temporary credentials via the AWS STS service, eliminating the need to hardcode or manage long-term credentials.
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.
✗
Store IAM credentials in the container image as environment variables
Why it's wrong here
Hardcoding credentials is insecure and violates best practices.
✗
Attach an IAM instance profile to the underlying EC2 instance
Why it's wrong here
SageMaker endpoints are managed services; you don't attach instance profiles directly.
✓
Create an IAM role with DynamoDB read access and assign it to the SageMaker endpoint as the execution role
Why this is correct
SageMaker assumes the execution role to access other AWS services.

✗
Retrieve temporary credentials from AWS Secrets Manager within the container code
Why it's wrong here
Secrets Manager is for secrets, but SageMaker can use execution role directly.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse SageMaker endpoints with EC2-based deployments and incorrectly think they need to manage instance profiles or embed credentials, when in fact SageMaker abstracts the underlying compute and uses an execution role for all API access.
Detailed technical explanation
How to think about this question
Under the hood, when you create a SageMaker endpoint with an execution role, SageMaker calls AssumeRole on your behalf to obtain temporary security credentials that are injected into the container's environment as AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_SESSION_TOKEN. These credentials are automatically rotated by AWS and scoped to the permissions of the execution role. In a real-world scenario, if the DynamoDB table is in a different account, you would also need to configure a cross-account IAM role and ensure the execution role has sts:AssumeRole permissions.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
