1. What is synthetic data primarily used for in machine learning workflows?

   1. Replacing all real-world data collection permanently
   2. Encrypting existing datasets for secure cloud storage
   3. Generating artificial datasets that preserve statistical properties without containing actual PII
   4. Converting unstructured data into structured databases

2. A data scientist wants to train a model on customer data but is concerned about exposing real PII. Which capability of synthetic data tools most directly addresses this concern?

   1. Automatic model deployment to production servers
   2. Generating realistic but anonymous user records
   3. Higher model accuracy compared to real data
   4. Faster training times due to smaller dataset sizes

3. When evaluating a synthetic data platform, which metric indicates how well the generated data will perform in downstream machine learning tasks?

   1. Number of columns generated
   2. Re-identification risk score
   3. Utility
   4. Dataset file size

4. A company discovers their original training data significantly under-represents a particular demographic group. How can synthetic data help address this imbalance?

   1. By removing all demographic information from the dataset
   2. By deleting data from over-represented groups
   3. By automatically labeling the missing demographic data
   4. By augmenting under-represented classes to balance the dataset

5. What does differential privacy provide in the context of synthetic data generation?

   1. A guarantee that the synthetic data will always be 100% useful for ML
   2. Faster generation speeds compared to non-private methods
   3. A method for automatically labeling training data
   4. Mathematical guarantees that make it computationally infeasible to identify individuals in the dataset

6. A developer notices their synthetic dataset produces a model with significantly lower accuracy compared to training on real data. What does this indicate about the synthetic data quality?

   1. The utility of the synthetic data is low
   2. The dataset contains too much PII
   3. The privacy guarantees are too strong
   4. The generation process is too fast

7. A healthcare startup wants to share patient data with external researchers while complying with privacy regulations. Which approach would best enable data sharing while protecting patient privacy?

   1. Generating synthetic patient records that maintain clinical patterns but contain no real PII
   2. Encrypting the data with a standard password
   3. Sharing the original dataset with a password-protected file
   4. Redacting only the patient names from the original data

8. What risk remains even when using synthetic data generated with strong privacy guarantees?

   1. The possibility that re-identification attacks could still succeed in certain settings
   2. Guaranteed model accuracy degradation
   3. Automatic bias elimination
   4. Complete elimination of all re-identification risk

9. An ML engineer evaluates two synthetic data platforms and finds Platform A has higher utility but lower privacy scores compared to Platform B. What trade-off is the engineer observing?

   1. Platform A is newer than Platform B
   2. Platform A is easier to integrate into pipelines
   3. Higher utility often comes at the cost of stronger privacy guarantees
   4. Platform B costs more money

10. When a synthetic dataset amplifies existing biases from the source data, what is the most likely underlying cause?

    1. The privacy settings were too strong
    2. The synthetic data generation algorithm introduced new biases
    3. The dataset was too small
    4. The source data was biased and the generator inherited those patterns

11. When selecting a synthetic data platform for a project with strict regulatory privacy requirements, which evaluation criterion is most critical?

    1. Generation speed
    2. Color scheme of the dashboard
    3. Number of export formats available
    4. Privacy metrics including re-identification risk

12. A synthetic data platform claims their technology completely eliminates re-identification risk. What should a cautious evaluator conclude about this claim?

    1. The platform is likely the best available option
    2. The claim contradicts the fundamental limitations of synthetic data
    3. The platform uses quantum encryption
    4. The claim is definitely true

13. When integrating synthetic data into an existing machine learning pipeline, which consideration is most important for ensuring successful deployment?

    1. How well the synthetic data integrates with existing pipeline tools and workflows
    2. The number of social media followers the vendor has
    3. The physical location of the vendor's servers
    4. The platform's logo design

14. Before training a machine learning model on synthetic data, what should data scientists audit the dataset for?

    1. The programming language used to generate it
    2. The file creation date
    3. The number of rows in the file
    4. Whether the data contains original biases from the source dataset

15. Which combination of evaluation criteria best captures the comprehensive assessment of a synthetic data platform as described in the lesson?

    1. Number of employees, funding rounds, and social media followers
    2. Utility, privacy metrics, and pipeline integration
    3. Price, customer service response time, and office location
    4. Color palette, font selection, and user interface animations
