The answer is to configure the Amazon Lex bot to use obfuscation for the credit card slot type, enable encryption in transit via HTTPS endpoints, and ensure logging is disabled or scrubbed for sensitive data. This works because Amazon Lex’s obfuscation feature replaces actual credit card values with asterisks in conversation logs and transcripts, preventing sensitive data exposure, while HTTPS (TLS) encrypts all data moving between the client and the Lex service, securing it from interception. On the AWS Certified AI Practitioner AIF-C01 exam, this scenario tests your understanding of Lex’s built-in data protection mechanisms versus general encryption practices—a common trap is confusing obfuscation (which hides data in logs) with encryption (which protects data in transit). Remember, obfuscation hides the card number from your eyes, while HTTPS hides it from eavesdroppers. A handy mnemonic: “Obfuscate the log, encrypt the path.”
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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 is deploying an Amazon Lex chatbot that processes customer credit card information. The company must ensure that the chatbot does not log sensitive data and that the data is encrypted in transit. Which THREE actions should the company take? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ensure the Amazon Lex endpoint uses HTTPS for all API calls
Option A is correct because Amazon Lex endpoints support HTTPS, which encrypts data in transit using TLS. By ensuring all API calls use HTTPS, the company protects sensitive credit card information from being intercepted during communication between the client and the Lex service.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Read the scenario before looking for a memorised answer.
✓
Enable audio logging in Amazon Lex with content redaction enabled
Why this is correct
Redaction removes sensitive data from logs.

✗
Enable CloudTrail data events for the Lex bot to capture conversation logs
Why it's wrong here
CloudTrail does not capture Lex conversation logs; Lex uses CloudWatch Logs.
✗
Enable S3 server access logs on the bucket storing the Lex bot configuration
Why it's wrong here
Server access logs do not capture Lex bot execution logs.
✓
Configure the Amazon Lex bot to use obfuscation for the credit card slot type
Why this is correct
Obfuscation replaces the actual value with asterisks in logs.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse CloudTrail data events (which log API activity) with conversation logging (which captures user utterances), leading them to incorrectly select option C as a solution for preventing sensitive data logging.
Detailed technical explanation
How to think about this question
Amazon Lex uses AWS KMS for encryption at rest and TLS 1.2+ for encryption in transit. Content redaction in audio logging automatically replaces sensitive slot values (e.g., credit card numbers) with '[REDACTED]' in logs, while obfuscation for slot types masks the value in the session and logs. These features work together to ensure PCI DSS compliance by preventing sensitive data exposure.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
