NEW QUESTION # 42
A Gen AI Specialist registered a new model in the Snowflake Model Registry and granted the USAGE privilege to a custom role, TRAINEE_ROLE.
When a new user with TRAINEE_ROLE tried to download the model artifacts with the GET command, an error occurred.
What would cause this error?
Answer: A
Explanation:
In the Snowflake Model Registry, models are treated as schema-level first-class database objects with a multi- tiered privilege hierarchy designed to separate operational inference from asset inspection and exfiltration.
The USAGE privilege on a model object permits a role to list the model and invoke its operational inference methods (e.g., using MODEL!PREDICT syntax) within a virtual warehouse. However, USAGE intentionally does not allow users to extract, inspect, or download the underlying raw code, serialized artifacts, binaries, or model weights.
To extract or download model artifacts directly (such as transferring files from the backing repository stage), a role must possess either the READ privilege or full OWNERSHIP on the model object. Because TRAINEE_ROLE was granted only USAGE, any attempt to retrieve model assets via internal stage operations or client GET commands fails due to insufficient object privileges.

NEW QUESTION # 43
When creating a Snowflake Document AI model, which object must have the CREATE SNOWFLAKE.ML.
DOCUMENT_INTELLIGENCE privilege?
Answer: A
Explanation:
Snowflake Document AI leverages zero-shot and fine-tuned multimodal models (specifically the Arctic-TILT architecture) to extract discrete data attributes from unstructured documents. Within Snowflake's object hierarchy, Document AI model builds (DOCUMENT_INTELLIGENCE objects) are managed as first-class, schema-level database entities.
Consequently, to initiate, build, and register a new Document AI pipeline within a target namespace, the user's active role must hold the CREATE SNOWFLAKE.ML.DOCUMENT_INTELLIGENCE privilege on the specific schema where the model build is instantiated (GRANT CREATE SNOWFLAKE.ML.
DOCUMENT_INTELLIGENCE ON SCHEMA < database > . < schema > TO ROLE < role > ;).
Securing database-level permissions provides container traversal (USAGE), but schema-level authority is required to instantiate schema-scoped ML assets. Virtual warehouses provide execution compute rather than metadata creation privileges, and stages serve as raw file storage repositories where stage-level privileges (READ, WRITE) govern file I/O rather than machine learning object creation. Without this explicit schema grant, attempts to initialize a Document AI build via Snowsight or SQL fail with authorization errors.

NEW QUESTION # 44
A Gen AI Specialist wants to use a Snowflake Cortex LLM function to classify customer questions into two categories: support and food.
The Specialist created a table named QUERIES containing the following values:
| ID | QUERY_TEXT |
| :--- | :--- |
| 1 | How do I reset my account password? |
| 2 | Where's the best sushi place in town? |
| 3 | I need help with a billing issue. |
Which command should be used?
```sql
Answer: B
Explanation:
The `SNOWFLAKE.CORTEX.CLASSIFY_TEXT` function assigns unstructured text to one or more predefined taxonomy categories without requiring manual prompt engineering.
Its SQL signature requires two positional arguments:
1. `text`: The string column or literal containing the text to be evaluated (here, `query_text`).
2. `categories`: An `ARRAY` of strings defining the target classification categories (here, `['support', 'food']`).
Option B follows this syntax: `SNOWFLAKE.CORTEX.CLASSIFY_TEXT(query_text, ['support', 'food'])`.
The function evaluates each row in `QUERIES` and returns a JSON object containing the assigned category label.
Option A is invalid because it omits the mandatory category array. Option C reverses the argument order.
Option D uses invalid named-argument syntax and incorrectly passes a model parameter, as
`CLASSIFY_TEXT` uses an internal specialized model rather than exposing user-selected foundation models.

NEW QUESTION # 45
This command is run:
```sqlSELECT SNOWFLAKE.CORTEX.COMPLETE
(
'llama2-70b-chat',
{
'role': 'user',
'content': 'what are the colors of an apple?'
},
{
'temperature': 0.7,
'guardrails': TRUE
}
);
```
This error is returned:
`Invalid argument types for function 'COMPLETES$V6': (VARCHAR(15), OBJECT, OBJECT)` What causes this error?
Answer: D
Explanation:
The `SNOWFLAKE.CORTEX.COMPLETE` function supports specific overloaded signatures:1.
`COMPLETE(model, prompt_string)`2. `COMPLETE(model, conversation_history_array [, options_object])
`When utilizing the three-argument signature containing an options configuration object (the third argument), Snowflake's SQL signature validator strictly enforces that the second argument (`prompt_or_history`) must be an **`ARRAY` of conversation message objects**, where each object contains valid `'role'` and `'content'` string keys.
In the query shown, the second argument was provided as a standalone, singular `OBJECT` (`{'role': 'user',
'content': ...}`) instead of being enclosed within array brackets (`[{'role': 'user', 'content': ...}]`). Consequently, Snowflake maps the arguments to `(VARCHAR, OBJECT, OBJECT)`, which does not match any valid function overload for `COMPLETE$V6`, raising an invalid argument type compilation exception. Enclosing the message object in an `ARRAY` resolves the signature mismatch.

NEW QUESTION # 46
Which Snowflake feature supports Retrieval Augmented Generation (RAG) with unstructured data?
Answer: B
Explanation:
Retrieval-Augmented Generation (RAG) over unstructured text requires an efficient search engine capable of identifying, ranking, and retrieving semantically relevant document chunks from text repositories.
Snowflake Cortex Search is the purpose-built service designed to support RAG over unstructured data. It indexes document content directly from Snowflake tables, generating vector embeddings and combining dense semantic vector retrieval with sparse keyword matching (BM25). Applications query Cortex Search to retrieve ranked context passages, which are then passed to LLMs to ground generated responses.In contrast, Cortex Analyst is designed for structured data querying via text-to-SQL semantic models; Cortex LLM Playground is a Snowsight testing interface for prompt exploration; and semantic views represent relational modeling constructs rather than unstructured vector retrieval engines.References & Study Guide Topics:* Snowflake Document Processing: Unstructured Data Indexing and Search* Cortex Architecture: Cortex Search Service as the Retrieval Backend for RAG===============
