The answer is AWS KMS, AWS CloudTrail, and Amazon GuardDuty. AWS KMS provides the encryption for model artifacts and training data at rest, directly satisfying SOC 2 and PCI DSS encryption mandates through managed keys. CloudTrail delivers the audit trail of all API calls and user activity, enabling the access auditing required by both compliance frameworks. GuardDuty continuously monitors VPC Flow Logs, DNS logs, and CloudTrail events to detect network threats like port scanning or data exfiltration, fulfilling the environment protection requirement. On the AWS Certified AI Practitioner AIF-C01 exam, this question tests your ability to map compliance controls to specific services rather than just memorizing features—a common trap is confusing CloudTrail with CloudWatch or overlooking that GuardDuty addresses network threats, not just instance-level security. Remember the mnemonic “KCG” (Keys, CloudTrail, Guard) to recall that encryption, auditing, and threat detection form the compliance triad for ML workloads.
AIF-C01 Practice Question: Security, Compliance and Governance for AI Solutions
This AIF-C01 practice question tests your understanding of security, compliance and governance for ai solutions. 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 is deploying a machine learning model that must comply with SOC 2 and PCI DSS. They need to ensure that the model artifacts and training data are encrypted, access is audited, and the environment is protected from network threats. Which THREE AWS services should they implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon GuardDuty
Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior, which helps protect the environment from network threats as required by SOC 2 and PCI DSS. By analyzing VPC Flow Logs, DNS logs, and CloudTrail events, it can detect anomalies such as port scanning or data exfiltration, directly addressing the need for network threat protection in a compliant ML deployment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Amazon DynamoDB Accelerator (DAX)
Why it's wrong here
DAX is a caching service for DynamoDB, not relevant to security compliance.
✓
Amazon GuardDuty
Why this is correct
GuardDuty continuously monitors for malicious activity and network threats.

✓
AWS KMS
Why this is correct
KMS provides encryption for data at rest and in transit for model artifacts and data.

✗
AWS WAF
Why it's wrong here
WAF protects web applications, but the primary threat protection for ML pipelines is more comprehensive via GuardDuty.
Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the distinction between network threat detection (GuardDuty) and web application layer protection (WAF), leading candidates to incorrectly choose WAF for general network threat protection when it only addresses HTTP/S-based attacks.
Detailed technical explanation
How to think about this question
GuardDuty uses integrated threat intelligence from AWS Security Hub and third-party feeds, along with machine learning models, to detect suspicious patterns like cryptocurrency mining or credential compromise. Under the hood, it processes VPC Flow Logs at the hypervisor level, ensuring no performance impact on instances, and generates findings that can be automatically remediated via Amazon EventBridge. In a real-world scenario, a compromised ML training instance attempting to exfiltrate data to an external IP would be flagged by GuardDuty's anomaly detection, which is critical for PCI DSS requirement 11.4 (use of intrusion-detection techniques).

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.
