Quick Answer
The answer is AWS CloudTrail. CloudTrail is the correct service because it provides a complete record of all API calls made to SageMaker endpoints, capturing details like the identity of the caller, the time of the request, and the source IP address, which is essential for security compliance audits. On the AWS Certified Machine Learning Engineer Associate MLA-C01 exam, this question tests your ability to distinguish between monitoring services: CloudTrail is for auditing API activity, while GuardDuty handles threat detection, Macie discovers sensitive data, and Config tracks configuration changes. A common trap is confusing CloudTrail with GuardDuty, but remember that CloudTrail is purely about logging who did what and when, not about detecting threats. For a quick memory tip, think "Trail of API calls" — CloudTrail leaves a trail of every API action.
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 wants to audit all API calls made to SageMaker endpoints for security compliance. Which AWS service should they enable?
AWS CloudTrail
CloudTrail records API calls for auditing.
Amazon GuardDuty
Why wrong: GuardDuty detects threats, not logs API calls.
AWS Config
Why wrong: Config monitors configuration changes, not API calls.
AWS CloudTrail
Why wrong: CloudTrail is correct but we need to place correct answer elsewhere.
Answer choices
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 records all API calls for auditing. GuardDuty is for threat detection, Macie for sensitive data discovery, and Config for configuration changes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
