The root key is the top-level in Snowflake's hierarchical key model.

• A. True
• B. False
• C. Not used
• D. Unknown

Answer: (A)

In Snowflake’s encryption setup, keys are arranged in a hierarchy with a single key at the very top. This root key acts as the anchor for the entire key chain, protecting the next level of keys (the key-encryption keys), which in turn protect the actual data encryption keys. Data remains secure because you can rotate or re-wrap the data keys without touching the root, keeping the top-level key stable. So, the root key is indeed the top-level element in Snowflake’s hierarchical key model.
