AIF-C01 Practice Question: A financial services company is deploying a…
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?
⚠ Common exam trap
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.
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
✓
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.

Option-by-option breakdown
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 CloudTrail
Why this is correct
CloudTrail provides audit logs of API calls for compliance requirements.
- ✓
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.
