- A
Use only aggregated data that does not include any patient-level details.
Why wrong: Aggregation may lose granularity needed for readmission prediction; de-identification of patient-level data is preferred.
- B
De-identify all protected health information (PHI) by removing or masking identifiers.
De-identification ensures compliance with HIPAA and protects patient privacy, allowing safe use of data for AI.
- C
Obtain written patient consent for every record used in training.
Why wrong: While consent is important, HIPAA allows use of de-identified data without consent; obtaining consent for each record is impractical.
- D
Store the data in a separate, encrypted environment with access controls.
Why wrong: While security measures are important, they do not remove PHI; de-identification is the primary requirement.
Quick Answer
The answer is to de-identify all protected health information (PHI) by removing or masking identifiers. This is correct because HIPAA mandates that any dataset containing individually identifiable health information must be stripped of those identifiers before it can be used for AI training without explicit patient authorization. In the context of building a patient readmission prediction model, identifiers like names, addresses, and medical record numbers must be removed or masked, while clinical notes can still be retained for predictive modeling as long as they no longer link back to a specific individual. On the Salesforce AI Associate exam, this question tests your understanding of the HIPAA Privacy Rule’s safe harbor method, which requires removing 18 specific identifiers. A common trap is assuming that simply anonymizing the data is enough, but the key is that de-identification must be explicit and verifiable. Memory tip: think “18 to de-identify” — remove all 18 HIPAA-listed identifiers before training any AI model.
AI Associate Data for AI Practice Question
This AI Associate practice question tests your understanding of data for ai. 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 healthcare organization uses Salesforce to develop an AI model for patient readmission prediction. They must comply with HIPAA regulations. The dataset includes patient names, addresses, medical record numbers, and detailed clinical notes. The data scientist plans to train a supervised model using historical readmission outcomes. What is the most important data governance step before model training?
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
De-identify all protected health information (PHI) by removing or masking identifiers.
Option B is correct because HIPAA mandates that protected health information (PHI) must be de-identified before it can be used for model training without patient authorization. Removing or masking identifiers such as names, addresses, and medical record numbers ensures the dataset no longer contains individually identifiable information, allowing the organization to comply with the HIPAA Privacy Rule while still using clinical notes for predictive modeling.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
While consent is important, HIPAA allows use of de-identified data without consent; obtaining consent for each record is impractical.

Why it's wrong here
While security measures are important, they do not remove PHI; de-identification is the primary requirement.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Salesforce often tests the misconception that security controls like encryption or access controls alone satisfy HIPAA compliance, when in fact de-identification is the primary requirement for using PHI in AI model training without patient consent.
Detailed technical explanation
How to think about this question
Under the hood, HIPAA's Safe Harbor method requires the removal of 18 specific identifiers, including names, geographic subdivisions smaller than a state, dates (except year), phone numbers, and medical record numbers. De-identification can also be achieved via the Expert Determination method, where a qualified statistician certifies that the risk of re-identification is very small. In practice, clinical notes often contain free-text PHI, so natural language processing (NLP) tools are used to detect and mask identifiers before training begins.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
