Snowflake SnowPro Specialty - Native Apps Sample Questions (Q143-Q148):

NEW QUESTION # 143
You are developing a Snowflake Native Application that processes sensitive dat a. During the application lifecycle management, including version updates, what steps should you take to ensure the data security and privacy of the consumers' data, especially considering that your development team might need access to a subset of the data for testing?

A. Utilize Snowflake's external functions to process the data in a secure enclave outside of Snowflake, minimizing the risk of data exposure. Ensure external functions called are encrypted.
B. Use Snowflake's data classification features to identify sensitive data and implement row-level security to restrict access to the development team.
C. Grant the development team direct access to the consumer's data warehouse to facilitate testing. Ensure proper auditing is enabled.
D. Create a separate Snowflake account for testing and populate it with synthetic data that mimics the structure and characteristics of the consumer's data.
E. Implement data masking and anonymization techniques to create a sanitized test dataset derived from the consumer's data. Provide the development team with access only to the masked data, via data sharing from the producer to consumer account.

Answer: D,E

Explanation:
The best answers are (B) and (D). Providing direct access to consumer data (A) is a major security risk. Option (B) utilizes masking/anonymization, crucial for protecting sensitive data. Data is shared from Producer account to Consumer accounts with masking policies applied for developers testing/access. Option (D) with synthetic data offers a secure testing environment. While data classification (C) and row-level security are useful, they aren't sufficient to protect data during development and testing, as developers could still potentially access sensitive data. External functions (E) could be used in conjunction with options B or D, but aren't a standalone solution.

NEW QUESTION # 144
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. Write a Python script leveraging the Snowflake Connector for Python to upload the files using multi-threading or asynchronous operations.
B. 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.
C. Use the Snowflake Visual Studio Code (VS Code) extension's built-in file upload feature, which automatically handles parallel uploads.
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: A,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 # 145
You've identified a critical security vulnerability in your Snowflake Native Application that requires immediate remediation. You need to release a patch, but you want to minimize the impact on consumers who are already using your application. Which of the following approaches is MOST suitable for deploying this patch? Select TWO that apply.

A. Develop a SQL script containing the necessary fixes and provide it to consumers with instructions on how to apply it manually to their installed application instances.
B. Leverage zero-downtime patching (if supported by Snowflake in future) by updating internal objects without requiring consumers to update or redeploy their installed application instances.
C. Issue an official announcement to all consumers that they need to uninstall and reinstall the application to receive the security fix.
D. Create a new version of the application package with the patch applied, and immediately update the default version of the application package to the new version.
E. Create a new version of the application package containing the patch. Ensure the new version addresses the vulnerability while maintaining backward compatibility with existing application interfaces and data formats, and then gradually roll out the new version to consumers using APPLICATION roles and grants.

Answer: B,E

Explanation:
Options C and E are the most suitable. Option C prioritizes security while minimizing disruption by maintaining backward compatibility and rolling out the patch gradually. Consumers can update at their own pace without breaking existing workflows. Option E (if it were a feature) is optimal for security patching as it does not require any end-user action at all. Option A immediately updating default version could disrupt those not prepared for change. Option B places a burden on the consumer and opens the door for manual errors. Option D is disruptive and inconvenient for consumers.

NEW QUESTION # 146
You are developing a Snowflake Native Application that needs to track usage metrics within consumer accounts. Specifically, you want to log the number of times a particular function within your application is called, and also store certain operational statistics. Which of the following storage options are available to you within the application package to persist these metrics, and what are their implications?
(Select TWO)

A. Using temporary tables within the application. These tables are automatically dropped at the end of the session.
B. Leveraging external stages (e.g., AWS S3) to store the metrics. The application would need the necessary IAM roles and stage configuration.
C. Utilizing User-Defined Functions (UDFs) with external network access to push metrics to an external logging service.
D. Using the 'APPLICATION' schema to create persistent internal stages. Data written to these stages will persist across installations and updates.
E. Creating permanent tables within the application package using the 'APPLICATION' schema. These tables persist across installations and updates.

Answer: D,E

Explanation:
Options B and E are the correct choices. The 'APPLICATION' schema allows for the creation of permanent tables within the application package. These tables persist across installations and updates, making them suitable for storing usage metrics. Similarly internal stages created using the 'APPLICATION' schema will persist data across versions. Option A is incorrect as temporary tables are session-based. Option C introduces external dependencies that are not typically ideal for tightly integrated Native Apps for internal metrics. Option D involves external network calls which might be restricted and less efficient for logging internal metrics.

NEW QUESTION # 147
An application provider wants to grant the 'EXECUTE MANAGED TASK' privilege to a consumer account for a specific managed task within their Snowflake Native App. The provider uses the following SQL statement:

However, when the consumer account attempts to execute the managed task, they encounter an error indicating insufficient privileges. Which of the following reasons could explain why the consumer account is unable to execute the task, and how could the provider resolve the issue? Select two correct answers.

A. The 'EXECUTE MANAGED TASK' privilege must be granted directly to the consumer account's user role, not the application role. The provider needs to identify the user role used by the consumer and grant the privilege to that specific role.
B. The 'EXECUTE MANAGED TASK' privilege needs to be granted with the 'WITH GRANT OPTION' clause to allow the consumer to further grant the privilege to other roles within their account.
C. The application role 'app_public' might not be activated within the consumer account's session. The consumer needs to ensure the application role is active using 'USE ROLE app_public;' before attempting to execute the managed task.
D. The managed task owner (the application) does not have the OWNERSHIP privilege on the database and schema where the managed task resides. The application must have OWNERSHIP on these objects.
E. The consumer account needs to explicitly grant the 'USAGE' privilege on the application database and schema to the application role 'app_public'. The provider needs to provide SQL to facilitate this in their setup script for consumer.

Answer: C,E

Explanation:
Option B is correct because the application role needs to be activated in the consumer's session to use the granted privilege. Option D is correct because even with the EXECUTE MANAGED TASK privilege, the application role needs USAGE privileges on the database and schema containing the task to access it. Option A is incorrect because granting to the application role is the correct method. Option C focuses on the provider's application setup, which does not directly relate to the consumer's inability to execute after a successful grant. Option E isn't applicable since the consumer is attempting to execute, not grant privileges to others.
