Snowflake SnowPro Specialty - Native Apps Sample Questions (Q228-Q233):

NEW QUESTION # 228
A Snowflake Native App provider has implemented an Event Table to capture application logs. They observe a significant performance degradation in their application queries when the Event Table grows beyond a certain size. Which of the following strategies can be implemented to mitigate the performance issue, assuming that frequent querying of the last 7 days of data is common? Select ONLY ONE answer.

A. Create a materialized view on top of the Event Table that filters for events within the last 7 days.
B. Increase the warehouse size used for querying the Event Table.
C. Implement a stored procedure that manually copies the last 7 days of data to a separate, smaller table.
D. Partition the Event Table by date, using the ' INSTALLATION_TIMESTAMP' column.
E. Disable automatic clustering on the Event Table.

Answer: A

Explanation:
Option B, creating a materialized view that filters for the last 7 days of data, is the MOST effective solution. Materialized views pre- compute and store the results of the query, so subsequent queries against the view are significantly faster. Increasing the warehouse size (Option A) might provide some improvement but does not address the fundamental issue of scanning the entire table. Partitioning (Option C) is not supported in Snowflake. Implementing a stored procedure (Option D) adds complexity and overhead. Disabling automatic clustering (Option E) will degrade performance.

NEW QUESTION # 229
You are developing a Snowflake Native Application that processes sensitive customer dat a. You need to ensure that the application is secure and compliant with data privacy regulations. Which of the following security measures are MOST effective when designing your application package? (Select TWO)

A. Bypass Snowflake's RBAC and authentication to manage access within the application.
B. Implement role-based access control (RBAC) to restrict access to sensitive data based on user roles within the application.
C. Use obfuscation techniques on the data within the application, making it harder to be read.
D. Encrypt all data at rest and in transit using Snowflake's built-in encryption features.
E. Store all sensitive data in external stages managed by the provider account to isolate it from the consumer's Snowflake environment.

Answer: B,D

Explanation:
Encrypting data at rest and in transit (A) is crucial for protecting sensitive information. Implementing RBAC (B) ensures that only authorized users can access specific data, enhancing security and compliance. Storing data in provider-managed external stages (C) would not allow consumer access to the data via Snowflake's data sharing capabilities. Obfuscation(D) is not the strongest mechanism. Bypassing Snowflake's RBAC(E) is a security risk and should never be done.

NEW QUESTION # 230
You are developing a Snowflake Native App that requires uploading multiple large data files (each > 50MB) to a stage for processing. Due to network limitations, you need to optimize the upload process. You have already created the stage and have necessary privileges. Which of the following approaches would be most effective for uploading the files efficiently?

A. Use the Snowflake Visual Studio Code (VS Code) extension's built-in file upload feature, which automatically handles parallel uploads.
B. Write a Python script leveraging the Snowflake Connector for Python to upload the files using multi-threading or asynchronous operations.
C. Utilize Snowflake's internal staging using 'PUT command on Internal stage for smaller file and external stage for larger file and then copy the larger file from external to internal by referencing file URL.
D. Use the 'PUT ' command with the 'PARALLEL' option enabled in SnowSQL.
E. Compress the files into a single ZIP archive before uploading using the 'PUT' command.

Answer: B,D

Explanation:
Options A and C are the most effective. Option A leverages SnowSQL's 'PARALLEL' option for concurrent uploads. Option C allows fine-grained control over upload concurrency using Python. Option B is less reliable for guaranteed performance tuning. Option D can introduce unnecessary overhead. Option E will increase complexity, so its not a direct approach to optimize upload process.

NEW QUESTION # 231
Consider the following Python code snippet used within a Streamlit application deployed as a Snowflake Native App:

A. The code will fail with a privilege error if the 'app_public' role does not have OWNERSHIP of the table 'my_table' .
B. The code will fail because the Snowflake Connector for Python requires explicit connection parameters to be defined even within a Native App context.
C. The code requires using the 'snowflake.snowpark' library instead of for optimized performance within native apps.
D. The code will execute successfully, assuming that Smy_table' exists, and the 'app_public' role has at least SELECT privilege on 'my_table' and USAGE privilege on the schema containing 'my_table' .
E. The code will execute without any privilege errors, assuming the necessary database and schema privileges are granted to the 'app_public' role.

Answer: D

Explanation:
The correct answer is D. When running within a Snowflake Native App, the Snowflake Connector for Python automatically uses the current session context, eliminating the need for explicit connection parameters. The code will execute successfully provided that the 'app_public' role has the appropriate privileges, which includes 'SELECT on 'my_table' and 'USAGE on the schema containing the table. Option A is partially correct, but option D provides more specific privilege requirements. Option B is incorrect because explicit connections aren't needed. Option C is incorrect because 'OWNERSHIP' isn't required, only 'SELECT. Option E is incorrect; using 'snowflake.snowpark' may offer performance benefits for data processing, but using "snowflake.connectofl is viable for simple queries.

NEW QUESTION # 232
You are developing a Snowflake Native App that needs to access a secured external API to enrich customer dat a. The API requires an OAuth 2.0 token stored securely. Which of the following approaches would you use within the application manifest and Snowflake objects to securely store and access this token, minimizing exposure and adhering to best practices?

A. Store the OAuth 2.0 token as a cleartext secret in a Snowflake stage and access it using external functions.
B. Store the OAuth 2.0 token as a masked comment within the application's SQL code. This will provide sufficient obfuscation.
C. Store the OAuth 2.0 token directly in the application's manifest file as a PARAMETER. This simplifies access within the application code.
D. Use Snowflake's SECRET object type to securely store the OAuth 2.0 token. Reference the SECRET object within the application using PARAMETERS in the manifest and utilize function in application code to retrieve it at runtime.
E. Hardcode the OAuth 2.0 token within the application's stored procedures. This ensures the token is readily available.

Answer: D

Explanation:
Storing secrets like OAuth tokens directly in the manifest or hardcoding them is a significant security risk. Using Snowflake SECRET objects is the recommended approach for securely managing sensitive information. The 'SYSTEM$GET SECRET function provides a secure way to retrieve the secret at runtime without exposing it in the code or manifest. Snowflake stages shouldn't be used to store secrets in clear text.
