問題 #14
You've developed a Snowflake Native Application. During the installation process in a consumer's account, the installation fails. The error message is vague and doesn't pinpoint the exact cause. What are the MOST effective steps you can take, in order , to diagnose the installation failure and provide the consumer with a resolution? (Select the top 3 steps)
答案：A,B,D
解題說明：
The most effective steps, in order, are: 1. D: Use 'SYSTEM$GET_PKG INSTALLATION ERRORS' in the provider account. This function is specifically designed to provide detailed error information about failed installations. It's the quickest way to get actionable insights. 2. B: Review Snowflake Event Tables. After getting a specific error from the , correlate the information with your application+s specific event logs. This helps understand the application-level context of the error. 3. A: Examine consumer's ACCOUNT_USAGE views. While less specific, checking query history and error logs in the consumer account can provide valuable insights into the environment and any potential conflicts. Option C is not the first step because Native Apps should ideally handle role creation. Sharing entire metadata (Option E) is a security risk and rarely necessary.
問題 #15
You are developing a Snowflake Native Application that processes sensitive financial data. You need to implement robust logging and auditing to comply with regulatory requirements. Which of the following strategies would provide the MOST secure and comprehensive auditing and logging solution within the context of a Snowflake Native App?
答案：C
解題說明：
Snowflake Event Tables provide a native, secure, and auditable way to track application events within the provider account. They are designed for observability and telemetry within the secure context of Snowflake. While options B and D are possible, they introduce complexities and potential security vulnerabilities related to managing access to external systems and ensuring data protection during transit. Option A provides insufficient application-specific logging. Option E, uses stages but not the snowflake event tables, stages are not the most suitable for application- specific data.
問題 #16
You are developing a Snowflake Native Application package that provides a set of UDFs for data transformation. The UDFs require specific Snowflake privileges to access data in consumer accounts. Which of the following methods can ensure your application has the necessary privileges when installed in a consumer account? (Choose all that apply)
答案：C,E
解題說明：
The application package 'manifest.yml' file is where you declare the resources your application needs and the privileges it requires. The 'GRANT APPLICATION ROLE ON statement, executed during the setup script, is the correct way to grant the APPLICATION role the necessary privileges on objects in the consumer account. Requiring consumers to manually grant privileges is not a scalable or secure solution. 'GRANT OWNERSHIP is generally not necessary or recommended as it gives the application full control over the object. Creating a separate role in the consumer account and having the application assume it is an overly complex solution when 'GRANT APPLICATION ROLE is available.
問題 #17
You are developing a Snowflake Native Application that includes a Python module for data transformation. This module relies on the pandas' and 'requests' libraries. You are using an 'environment.yml' file to manage dependencies. Which of the following 'environment.yml' configurations is the MOST secure and correct way to define these dependencies for your application? Assume you want to install these packages directly from conda-forge channel.
答案：A
解題說明：
Option E is the MOST secure and correct. Here's why: Specifying Versions: Explicitly pinning the versions of 'pandas' and requests' (e.g., 'pandas=l .3.5' , ensures consistent behavior across different environments and prevents unexpected issues caused by updates to these libraries. This greatly enhances the reproducibility and stability of your application. Using conda-forge Channel: Specifying 'conda-forge' as the channel is generally recommended for Snowflake Native Apps as it provides a broader selection of packages and often includes versions compatible with the Snowflake environment. It also tends to have more up-to-date packages. Avoiding 'pip': While 'pip' can be used, it's generally better to use 'conda' for managing dependencies in a 'environment.ymr file as it can handle non-Python dependencies as well and integrates better with Conda environments. Option A is less desirable because it relies on 'pip' without a specified channel, which can lead to inconsistencies and potential security vulnerabilities. Option B is better than A because it uses conda-forge but lacks version pinning. Option C uses 'defaults' channel which is less preferable to conda-forge and lacks version pinning. Option D unnecessarily mixes pip with the Conda package manager.
問題 #18
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?
答案：A,B
解題說明：
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.
