- A
AWS CloudTrail
Correct. CloudTrail records all API calls to SageMaker endpoints, providing a full audit trail for security compliance.
- B
Amazon GuardDuty
Why wrong: Incorrect. GuardDuty is a threat detection service that monitors for malicious activity, not an API auditing service.
- C
AWS Config
Why wrong: Incorrect. AWS Config evaluates resource configurations and compliance, but does not log API call details.
- D
AWS CloudTrail
Correct. Option D is identical to option A; both correctly identify AWS CloudTrail as the service to enable for API auditing.

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 audit all API calls made to SageMaker endpoints for security compliance. Which AWS service should they enable?
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 CloudTrail
AWS CloudTrail is the correct service because it records all API calls made to SageMaker endpoints, including the caller identity, time, source IP, and request parameters. This provides a complete audit trail for security compliance, enabling analysis of who made what changes and when. CloudTrail is specifically designed for governance, compliance, and operational auditing of AWS API activity. Note that both options A and D list 'AWS CloudTrail' and are therefore both correct. This duplication is an artifact in the question design but does not change the fact that CloudTrail is the right service.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse GuardDuty's threat detection capabilities with CloudTrail's auditing function, or mistakenly think AWS Config's configuration tracking includes API call logging. Additionally, be aware that duplicate correct options (A and D) may appear in some questions; both are valid selections.
Detailed technical explanation
How to think about this question
CloudTrail delivers log files to an S3 bucket in JSON or gzip format, with each event containing fields like eventSource (e.g., sagemaker.amazonaws.com), eventName (e.g., InvokeEndpoint), and userIdentity. For SageMaker, CloudTrail captures all control plane operations (e.g., CreateEndpoint, UpdateEndpoint) and data plane operations (e.g., InvokeEndpoint) when data events are enabled. In a real-world scenario, enabling CloudTrail on SageMaker endpoints is critical for SOC 2 or PCI DSS audits to demonstrate who invoked a model and when.
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.
