COF-C03 Account Management and Data Governance Practice Question
Which of the following describes the purpose of 'Object Tagging' in Snowflake?
⚠ Common exam trap
Candidates often think tags are used for performance optimization or data clustering. They fail to recognize that tags are primarily metadata tools for discovery, compliance, and cost reporting purposes.
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
✓
To logically group objects for discovery and compliance reporting.
Object tagging allows administrators to assign metadata to objects (like tables, columns, or warehouses) to facilitate discovery, tracking, and governance. Tags are useful for identifying sensitive data, tracking costs, or enforcing compliance. This is a crucial feature for large organizations that need to report on data usage, lifecycle, and sensitivity across thousands of objects, making it easier to manage and audit data at scale.
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 encrypt sensitive data at the column level.
Why it's wrong here
Object tagging is for metadata management and governance, not for encryption. Encryption is handled by features like Tri-Secret Secure or column-level masking. Tags do not alter the way data is stored or protected; they only provide descriptive labels for organizational and audit purposes.
- ✓
To logically group objects for discovery and compliance reporting.
Why this is correct
Object tagging provides a mechanism to attach labels to objects, which can then be used to query and report on the data. For example, a tag like 'PII: True' helps security teams identify and audit all sensitive columns across the entire account for compliance documentation.
- ✗
To restrict user access based on their network location.
Why it's wrong here
Access restriction by network location is handled by Network Policies. Object tags are strictly for metadata and do not contain logic for enforcing connection-level security. Attempting to use tags for access control would be ineffective as they do not influence the authentication or authorization process.
- ✗
To automatically optimize query performance.
Why it's wrong here
Query performance optimization is managed through features like result set caching, clustering keys, and warehouse sizing. Object tags do not interact with the query engine or optimizer. They are descriptive labels only and have no impact on the execution speed or resources used by SQL queries.
