질문 # 49
You are tasked with building a dashboard in Looker Studio to visualize data from a Snowflake database. The data contains sensitive information, and the security team requires that only authorized users can access specific data based on their role. The Snowflake database has roles defined: 'ANALYST, 'MANAGER, and 'EXECUTIVE. The 'SALES DATA' table contains a 'REGION' column. 'ANALYST' should only see data for their assigned region, 'MANAGER should see data for their region and direct reports regions, and 'EXECUTIVE should see all regions. Which of the following is/are the MOST secure and efficient way(s) to implement row-level security in Snowflake and integrate it with Looker Studio without duplicating the data?

A. Create dynamic data masking policies in Snowflake to redact sensitive 'SALE_AMOUNT data based on roles and connect Looker Studio using a service account.
B. Implement a Snowflake stored procedure that accepts a user's role as input and returns the filtered data. Connect Looker Studio to this stored procedure.
C. Import the 'SALES DATA' table into Looker Studio and implement data blending with a user role mapping table to filter the data within Looker Studio.
D. Implement Row Access Policies in Snowflake based on the USER NAME() or CURRENT ROLE() functions to filter the 'SALES DATA' table directly. Grant appropriate roles to users and connect Looker Studio using a service account that has the necessary privileges.
E. Create separate Snowflake views for each role, filtering the data based on the 'REGION' column. Connect Looker Studio to the appropriate view based on the user's role.

정답：A,D

설명：
Row Access Policies (RAP) in Snowflake provide the most secure and efficient way to implement row-level security. By defining policies based on the user's role, you can ensure that users only see the data they are authorized to access directly at the Snowflake level. Combining RAPs with dynamic data masking for 'SALE_AMOUNT adds an extra layer of security by redacting sensitive data based on the user's role. Option A requires managing multiple views, which can be cumbersome. Option B introduces complexity with stored procedures. Option D moves security logic into Looker Studio, which is less secure and can be bypassed. Using a service account with appropriate privileges ensures that Looker Studio can access the data securely and apply the defined Row Access Policies. Options C is correct because it keeps security logic within Snowflake. Option E is correct because it provides additional data masking depending on the security policies for sale amount.

질문 # 50
You have a table 'product_catalog' containing a 'description' column of type TEXT, and a 'tags' column which is a VARIANT containing an array of strings representing tags associated with the product. You need to build an efficient search mechanism that allows users to find products matching specific tags. Considering scalability and performance for large catalogs, which of the following methods using table functions and Snowflake's search capabilities would be most suitable? Choose all that apply.

A. Create a search optimization service on the 'product_catalog' table including the 'description' and 'tags' columns. When querying, use a combination of CONTAINS() for 'description' and ARRAY_CONTAINS() on the 'tags' column and a 'SEARCH' clause to filter results.
B. Use a Java UDF to iterate over the 'tags' array and check if any of the tags match the search terms. Apply this UDF in a WHERE clause along with a CONTAINS() check on the 'description'
C. Create a view that flattens the 'tags' array using LATERAL FLATTEN into a 'tag' column, and then create a full-text index on the 'description' column. Query the view using CONTAINS() or LIKE operator on the 'description' and EQUALS operator on the 'tag' column.
D. Create a search optimization service on the 'product_catalog' table including the 'description' column. When querying, use a combination of CONTAINS() for 'description' and ARRAY_CONTAINS() on the 'tags' column.
E. Create a search optimization service on the 'product_catalog' table including the 'description' and 'tags' columns. Use LATERAL FLATTEN to expand the 'tags' array and then create an index on the flattened 'tag' values.

정답：A,D

설명：
Search optimization service in Snowflake is designed to accelerate search queries and is best practice here. Using 'ARRAY on the 'tags' column lets you directly check if the array contains specific tags. Using on the 'description' column can search for specific search terms in your description. Using a 'SEARCH' clause can improve search performnce significantly. Option C and E, are both correct, since they use contains as well as the array_contains but option E includes the use of Search which is more effiecient. Option A is incorrect, as indexes are not allowed on flattened data. UDF will have performance issues. Creating a view and indexing the view is not optimal as querying directly with CONTAINS on the tags column gives faster results.

질문 # 51
You are tasked with analyzing website clickstream data stored in a Snowflake table named 'clickstream_data'. The table contains a 'variant' column named 'event data' that holds JSON data representing various events like 'page view', 'button click', and 'form submission'. You need to extract the 'page_url' from 'page_view' events, the 'button id' from 'button click' events, and the 'form id' from 'form submission' events. Design the most efficient Snowflake SQL query to achieve this, considering the performance implications of variant parsing and filtering. Assume the 'event_type' is directly available within the variant object as well. Which of the following queries would be most efficient?

A. Option C
B. Option D
C. Option E
D. Option A
E. Option B

정답：A

설명：
Option C is the most efficient. Snowflake's native variant access is generally faster than using 'PARSE_JSON' Also, explicit casting to VARCHAR ensures consistency in the output data type. Option A although correct will produce an output that is of variant type for all fields. Option B is incorrect because if none of the when conditions matches, then it returns NULL. Option D uses PARSE JSON unneccessarily making it slower. Option E uses GET which is used to extract data from an object within VARIANT and not to directly evaluate the VARIANT column.

질문 # 52
What role do system functions play in data manipulation within Snowflake?

A. System functions manage query execution plans.
B. They solely work on numeric data.
C. System functions perform administrative tasks.
D. They modify database structures.

정답：C

설명：
System functions in Snowflake perform administrative tasks, aiding in data manipulation and management.

질문 # 53
You are designing a data pipeline that requires executing a sequence of SQL statements conditionally based on the success or failure of previous steps. You want to encapsulate this logic within a stored procedure in Snowflake. Which of the following approaches can be used to achieve this conditional execution within a stored procedure, and what are their key differences regarding error handling and control flow?

A. Using Javascript as the stored procedure language and leveraging its built-in 'try...catcW blocks. SQL statements are executed using the Snowflake Javascript API, and Javascript's error handling mechanisms are used to manage exceptions and control the flow. This offers more flexibility in handling complex error scenarios and integrating with external systems.
B. All of the above approaches can be used, but they differ in terms of complexity, performance, and error handling capabilities.
C. Using 'IF...THEN...ELSE' statements to check the 'SQLCODE' or 'SQLSTATE after each SQL statement. If the 'SQLCODE indicates an error, the procedure can execute alternative steps or terminate gracefully. This allows for fine-grained control over the execution flow based on the success or failure of individual statements.
D. Using 'TRY...CATCH' blocks within the stored procedure to handle exceptions and control the flow based on error codes. Each SQL statement is wrapped in a TRY block, and if an error occurs, the CATCH block is executed to log the error and potentially execute alternative steps. This ensures that the procedure continues to execute even if some steps fail.
E. Utilizing Snowflake's Task feature to define dependencies between different SQL operations. Each SQL statement is defined as a separate Task, and dependencies are created to ensure that Tasks are executed only if their preceding Tasks succeed. This provides a robust and scalable way to manage complex data pipelines with conditional execution.

정답：B

설명：
All the mentioned approaches are valid for conditional execution within a Snowflake stored procedure or data pipeline. blocks provide a general mechanism for handling exceptions. 'IF...THEN...ELSE statements with 'SQLCODE or 'SQLSTATE& allow for more granular control based on specific error codes. Javascript offers flexibility and integration capabilities. Snowflake Tasks provide a robust and scalable solution for managing complex data pipelines with dependencies. The best approach depends on the specific requirements of the data pipeline, including complexity, performance, and error handling needs.
