MLA-C01 Practice Question: ML Solution Monitoring, Maintenance and Security

This MLA-C01 practice question tests your understanding of ml solution monitoring, maintenance and security. 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 company wants to ensure that only authorized users and services can invoke a SageMaker real-time endpoint. Which AWS service can be used to manage access control?

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

✓

AWS Identity and Access Management (IAM)

AWS Identity and Access Management (IAM) is the correct service because it allows you to create fine-grained permissions policies that control which users, roles, or services can invoke a SageMaker real-time endpoint via the InvokeEndpoint API. By attaching IAM policies to principals (e.g., IAM users, roles, or federated identities), you can restrict invocation based on conditions such as source IP, VPC endpoint, or MFA, ensuring only authorized entities can send inference requests.

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.

  • ✗

    Amazon CloudWatch

    Why it's wrong here

    CloudWatch is for monitoring, not access control.

  • ✓

    AWS Identity and Access Management (IAM)

    Why this is correct

    IAM policies can grant or deny access to invoke SageMaker endpoints.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    AWS CloudTrail

    Why it's wrong here

    CloudTrail is for logging API calls, not access control.

  • ✗

    AWS Config

    Why it's wrong here

    AWS Config is for compliance and resource tracking, not access control.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse monitoring or auditing services (CloudWatch, CloudTrail, Config) with access control, mistakenly thinking they can restrict API calls when they only observe or log them.

Detailed technical explanation

How to think about this question

Under the hood, SageMaker endpoints are secured via IAM resource-based policies (attached to the endpoint) or identity-based policies (attached to the caller). The InvokeEndpoint API call is authenticated using AWS Signature Version 4, and IAM evaluates the effective permissions at runtime, including condition keys like sagemaker:TargetModel or aws:SourceVpce. In a real-world scenario, you might combine IAM with a VPC endpoint policy to restrict inference traffic to a specific VPC, preventing data exfiltration over the public internet.

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.
