COF-C03 Data Collaboration Practice Question
A data provider wants to share a subset of data with a specific consumer while ensuring the consumer cannot see any other tables in the same database. What is the most secure and efficient method to achieve this?
⚠ Common exam trap
Many candidates mistakenly select standard views or table duplication, forgetting that standard views expose underlying metadata and schema structures, violating isolation and security requirements.
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
✓
Use a Secure View in a dedicated share-ready schema.
Secure Views are essential for sharing specific data subsets because they hide the underlying query logic and schema structure from the consumer. By using a Secure View, the provider maintains granular control over column and row visibility, ensuring data privacy across account boundaries. This approach prevents unauthorized metadata discovery, which is critical in multi-tenant data sharing environments where isolation between different business units or external partners must be strictly maintained for compliance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Grant usage on the entire database to the consumer's role.
Why it's wrong here
Granting database usage allows the consumer to see all schemas and objects within that database, violating the requirement to share only a subset. This broad privilege grants too much visibility, bypassing the principle of least privilege required for secure data collaboration between distinct Snowflake accounts.
- ✗
Create a shared database and grant access to the base tables.
Why it's wrong here
Sharing base tables directly exposes the entire structure and content of the underlying data. This approach fails to protect sensitive columns or filtered rows, increasing the risk of exposing unintended data points to the consumer during the collaboration process, which is not recommended for restricted subsets.
- ✓
Use a Secure View in a dedicated share-ready schema.
Why this is correct
Secure Views are specifically optimized to hide internal metadata and query structures from unauthorized users. By placing the view in a dedicated schema, the provider enforces strict isolation, ensuring the consumer only interacts with the specific subset defined by the view logic without discovering other database objects.
- ✗
Enable Secure Data Sharing and grant SELECT on all tables.
Why it's wrong here
Granting SELECT on all tables defeats the purpose of providing a specific subset of data. This method requires manual intervention for every new table, is prone to human error, and fails to provide the row-level or column-level security necessary for protected data collaboration scenarios.
