Option A is correct. This sequence of commands sets an account-level allowlist for 'mistral-large? and 'snowflake-arctic' , thereby restricting general access to other models. It then explicitly grants the access to the 'claude-3-5- sonnet' model object using its dedicated application role This ensures that 'claude-3-5-sonnet' is accessible only to that specific role and not globally through the allowlist. The ' call is often recommended after modifying 'CORTEX MODELS ALLOWLIST to ensure changes are applied. Option B is incorrect because 'ALTER ACCOUNT requires the 'ACCOUNTADMI!V role, and setting to 'claude-3-5-sonnet' would make it globally available, contradicting the requirement. Option C is incorrect because model-level RBAC for base models in 'SNOWFLAKE.MODELS' is primarily applied using application roles (e.g., 'CORTEX-MODEL-ROLE'), not directly with 'GRANT USAGE ON MODEL'. Option D is incorrect. While clearing the allowiist is a valid part of a strategy, GRANT USAGE ON ALL MODELS IN SCHEMA SNOWFLAKE.MODELS' would grant access to 'all' models in that schema, which contradicts the requirement for 'claude-3-5-sonnet' to be exclusive to the data science team and not generally available. Option E is incorrect because 'ALTER ACCOUNT requires the ACCOUNTADMIN' role, and setting the allowlist to 'claude-3-5-sonnet' would make it generally available, violating the isolation requirement.
