Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native Application and need to implement robust logging for troubleshooting purposes. You want to capture detailed information about function calls, including input parameters and return values. Which of the following approaches offers the MOST comprehensive and secure solution for logging within a Snowflake Native Application, considering the limitations imposed by the Snowflake environment?

A) Employing 'EXECUTE IMMEDIATE to write log messages directly to a dedicated logging table within the consumer's account.
B) Leveraging Snowflake's event tables and configuring the application to emit custom events, then creating views on those event tables within the consumer's account.
C) Using 'SYSTEM$LOG' with debug level logging and capturing logs in a secure internal stage, managed by the provider, ensuring data privacy and limited consumer access.
D) Writing log messages to an external stage (e.g., AWS S3, Azure Blob Storage) that is accessible to both the provider and consumer accounts.
E) Using ' SYSTEM$LOG' with trace level logging and store the logs into internal stage, accessible only by the application's service user.

2. You're designing a Snowflake Native Application that leverages Snowpark Container Services (SPCS) and you are creating a CI/CD pipeline for deploying your application to multiple Snowflake regions. As part of the pipeline, you want to automate the creation of a Compute Pool. Which of the following approaches represents the MOST robust and repeatable method for creating the Compute Pool across all regions, considering factors like consistency and potential differences in available instance families?

A) Manually create the Compute Pool in each region using the Snowflake web interface, ensuring the parameters are identical across all instances.
B) Create a Compute Pool in one region and then clone it to all other regions using the 'CREATE CLONE syntax.
C) Compute Pools created are global objects, so the pool automatically exists across all regions.
D) Use a Snowflake Script (SnowSQL) to create the Compute Pool, retrieving the available instance families dynamically using 'SYSTEM$GET_CP POLICY' and selecting the appropriate instance family based on regional availability. Store common configurations in environment variables.
E) Use a Snowflake Script (SnowSQL) to create the Compute Pool, hardcoding the instance family and other parameters directly into the script.

3. You are developing a Snowflake Native Application that utilizes Snowpark Container Services to perform complex image processing. The application needs to securely access data stored in the consumer's Snowflake account, specifically a table named 'USER IMAGES' in the schema 'RAW DATA'. The container image is built and pushed to Snowflake's internal registry. Which of the following steps are necessary to ensure the container service can access this data securely and efficiently within the consumer's account without exposing credentials directly in the container environment?

A) Create a Snowflake database role, grant SELECT privileges on ' to this role, and then assign this role to the service account used by the container service through an entitlement.
B) Configure a Snowflake OAuth integration and associate it with the container service. The container application would then use the OAuth client credentials to obtain an access token and authenticate with Snowflake.
C) Grant the SNOWFLAKE CONTAINER SERVICE role to the account administrator and use the administrator's credentials within the container service's code.
D) Create a Snowflake network rule that allows access to all Snowflake internal IPs. Associate this rule with the container service's network policy.
E) Create a Snowflake service account and grant it SELECT privileges on the 'RAW DATA.USER IMAGES table. Store the service account's credentials as environment variables within the container service's specification.

4. You are building a Snowflake Native App that aggregates data across multiple consumer accounts. Your app needs to securely access data in each consumer's Snowflake account without requiring them to share their credentials directly. You are evaluating different options for secure data access. Which of the following strategies are viable and recommended to implement this, maximizing security and minimizing administrative overhead for the consumer?

A) Require consumers to grant SELECT privileges on their tables directly to the application's account. This necessitates the consumer to manage grants directly.

B) Utilize Snowflake's Native App data sharing capabilities where the provider app shares data products back to the consumer account and the consumer account can use this inside their apps.

C) Implement a data sharing agreement where consumers create a share from their account and grant usage to your application's account using secure data sharing. The application account can then create a database from this share.

D) Use Snowflake Data Clean Rooms to allow the app to query data from the consumers accounts.

E) Have consumers create and share a JWT (JSON Web Token) with your application. The JWT will be used to authenticate against their Snowflake instance via an external function.

5. You are designing a Snowflake Native Application that provides a data enrichment service. Consumers provide their data via a secure data share, and your application enriches it with external datasets within your provider account. To ensure data security and prevent accidental data leakage, which of the following strategies should you implement when designing the application's logic (select all that apply)?

A) Use fully qualified names when referencing objects within the consumer's shared data (e.g.,
B) Implement strict input validation and sanitization of the data received from the consumer to prevent SQL injection or other malicious attacks that could lead to data exfiltration.
C) Create a dedicated service user within your provider account with restricted privileges to access the shared data. The application's logic should execute using this service user's context.
D) Grant the consumer's application role 'OWNERSHIP' privilege on the data share. This simplifies data management for the consumer.
E) Log all data access and modifications performed by the application, including the user context (application role), timestamps, and objects accessed, for auditing purposes.
