CCAO-F Prompting and Context Engineering Practice Question
When designing a prompt to handle sensitive user data, which THREE of the following practices should be prioritized for security and compliance?
⚠ Common exam trap
Candidates often assume the model can be 'told' to ignore PII, neglecting the risk of data leakage and failing to sanitize sensitive data at the application layer before API submission.

Correct answer & explanation
✓
Anonymize all PII (Personally Identifiable Information) before sending it to the API.
Security in LLM applications relies on the principle of least privilege and data minimization. You should never pass PII or sensitive data into the prompt if it is not absolutely necessary. Sanitizing inputs and using system prompts to enforce strict data handling policies ensures that the model acts as a safe intermediary, protecting user privacy and adhering to compliance requirements like GDPR or SOC2.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Anonymize all PII (Personally Identifiable Information) before sending it to the API.
Why this is correct
Anonymization is the first line of defense. By replacing real names, emails, or IDs with tokens or dummy data before the information reaches the model, you ensure that even if the prompt is logged, no sensitive user data is exposed. This is a critical step for data privacy compliance.
- ✓
Use the system prompt to explicitly define the data privacy boundaries and prohibit the model from storing input data.
Why this is correct
System prompts can enforce operational constraints. By telling the model to act as a stateless processor and not retain information about the user, you create an additional layer of behavioral guardrails. While this doesn't replace backend security, it reinforces the desired security posture of your application.
- ✗
Include the user's password in the prompt to verify their identity before responding.
Why it's wrong here
Passwords should never be sent to an LLM. This is a severe security vulnerability that would expose user credentials in API logs. Identity verification must be handled by your backend authentication system, never by the LLM itself. The LLM should only receive the tokens required to process the request.
- ✗
Use as many few-shot examples as possible to ensure the model behaves consistently.
Why it's wrong here
More is not better when it comes to few-shot examples. Over-populating the prompt with examples increases the surface area for potential data leakage if those examples happen to contain sensitive info. Only use the absolute minimum number of examples required to achieve the desired model behavior for the task.
- ✓
Set strict input validation in your application layer before passing content to Claude.
Why this is correct
Input validation is essential for preventing prompt injection and ensuring that only sanitized, expected data reaches the model. By filtering inputs on your server before calling the API, you protect against malicious attempts to manipulate the model into revealing sensitive information or bypassing your security policies.
