DEA-C02 Data Governance Practice Question
An organization wants to track all data access in their Snowflake account for compliance. They need to know which columns were accessed by which queries, and they want to retain this information for at least one year. Which Snowflake feature should they use to meet this requirement?
⚠ Common exam trap
The trap here is assuming that Query History includes column-level access details, when it only records query metadata.
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
✓
Access History
Access History is specifically designed to provide column-level access auditing, capturing which columns were read or written by queries. It retains data for 365 days, satisfying the one-year retention requirement. Query History lacks column-level detail and has a shorter retention. Login History and Object Dependencies do not track data access. Thus, Access History is the correct feature.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Login History
Why it's wrong here
Login History records authentication events such as successful and failed logins, but it does not track data access or column usage. It is useful for security monitoring but not for auditing which columns were accessed. The retention is also limited. Therefore, it is not suitable for this requirement.
- ✗
Object Dependencies
Why it's wrong here
Object Dependencies shows relationships between objects, such as which views reference which tables, but it does not track data access or column usage. It is a metadata feature for impact analysis, not for auditing. It cannot provide information about who accessed which columns. Hence, it is not the correct choice.
- ✓
Access History
Why this is correct
Access History captures column-level access information for queries, including which columns were read and written. It is designed for auditing and compliance, and the data is retained for 365 days. This meets the requirement of tracking column access and retaining for one year. Therefore, Access History is the correct feature.
- ✗
Query History
Why it's wrong here
Query History records metadata about queries, such as the SQL text, user, and duration, but it does not provide column-level access details. It cannot tell you which columns were accessed. Additionally, Query History is retained for 14 days by default, not one year. Thus, it does not meet the requirement for column-level tracking and long retention.
