DEA-C02 Data Governance Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  To hide data from unauthorized users.

  Why it's wrong here

  Tags themselves do not provide security or access control; they are merely metadata. The security and masking are performed by separate policy objects that reference these tags. A tag provides the label that tells the policy engine where to apply the protection, but it is not the protection itself.

• ✓

  To classify data and facilitate governance policy application.

  Why this is correct

  Tags allow for the classification of data assets, enabling administrators to identify sensitive information and apply policies programmatically. This is a fundamental component of data governance, as it provides a structured way to manage and protect data across large, complex schemas without requiring manual column-level configuration.

• ✗

  To store physical data for backup purposes.

  Why it's wrong here

  Tags are metadata objects and cannot store, backup, or retrieve physical data records. They describe data, they do not contain it. Using tags as a backup mechanism is fundamentally impossible within the Snowflake architecture, as they do not hold any actual data content or history.

• ✗

  To increase the performance of queries.

  Why it's wrong here

  Tags are not related to query optimization or performance. They are purely administrative and governance-focused objects. Adding tags to a table has no impact on how the query optimizer handles the data, meaning they provide no benefit for improving the speed or efficiency of SQL execution.
