- A
Enable AWS CloudTrail for the SageMaker endpoint API calls
CloudTrail logs all API calls, providing an audit trail for security analysis.
- B
Enable AWS Config to monitor endpoint configuration changes
AWS Config tracks resource configuration changes and can detect unauthorized modifications.
- C
Enable SageMaker Data Capture on the endpoint
Why wrong: Data Capture is for collecting inference input and output for later analysis, not for security monitoring.
- D
Enable SageMaker Model Monitor for the endpoint
Why wrong: Model Monitor is used for detecting data drift and model quality issues, not for security monitoring.
- E
Enable Amazon GuardDuty for the endpoint
Why wrong: GuardDuty is a threat detection service for AWS accounts and workloads, but it does not specifically monitor SageMaker endpoint API calls or configuration changes at the resource level.
Quick Answer
The correct actions are enabling AWS Config to monitor endpoint configuration changes and using AWS CloudTrail to log API calls for security monitoring of SageMaker endpoints. CloudTrail records every API call made to the SageMaker endpoint, capturing details like the identity of the caller, source IP, and time of the request, which directly supports identifying unauthorized access attempts. AWS Config continuously tracks and evaluates changes to the endpoint’s configuration, such as model updates or instance type modifications, and can trigger alerts for any unauthorized tampering. On the AWS Certified Machine Learning Engineer Associate MLA-C01 exam, this pairing tests your ability to distinguish between security monitoring tools and operational monitoring tools—a common trap is confusing SageMaker Model Monitor or Data Capture (which handle data drift and performance) with security controls. Remember the memory tip: “CloudTrail catches the call, Config catches the change.”
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. 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.
A company has deployed a SageMaker endpoint for real-time inference. The security team needs to monitor for potential security threats such as unauthorized access attempts and tampering with the model configuration. Which TWO actions should the team take? (Choose TWO.)
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
Enable AWS CloudTrail for the SageMaker endpoint API calls
CloudTrail logs all API calls to the SageMaker endpoint, including who made the call and from where, which helps identify unauthorized access. AWS Config continuously monitors endpoint configuration changes and can trigger alerts when changes are made without authorization. SageMaker Model Monitor is for data drift, not security. Data Capture captures input/output for monitoring model performance, not security. GuardDuty is a threat detection service for AWS accounts and workloads, but it does not directly monitor SageMaker endpoints specifically.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Trap categories for this question
Command / output trap
Data Capture is for collecting inference input and output for later analysis, not for security monitoring.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related MLA-C01 questions on access control and AAA configuration.
