Snowflake SnowPro Advanced: Data Engineer (DEA-C02) 認定 DEA-C02 試験問題 (Q124-Q129):

質問 # 124
Which of the following statements are TRUE regarding Snowflake's Fail-safe mechanism and its relation to Time Travel? (Select all that apply)

A. Fail-safe is automatically enabled for all Snowflake accounts and requires no configuration.
B. Users can query data directly from Fail-safe using SQL commands if Time Travel is insufficient.
C. Fail-safe is exclusively used by Snowflake to recover data in the event of a catastrophic system failure, and users have no direct access.
D. The Fail-safe period starts immediately after the Time Travel retention period ends.
E. Fail-safe provides a historical data retention period of 7 days, similar to the default Time Travel setting.

正解：A、C、D

解説：
Fail-safe is automatically enabled and managed by Snowflake (B). It kicks in after Time Travel (C) and is not directly accessible to users (E). Users cannot query data from Fail-safe using SQL commands. Fail-safes duration depends on the Snowflake Edition but not for the same days as time travel.

質問 # 125
A data provider wants to create a Listing in the Snowflake Marketplace. They want to ensure that consumers can only access the data in a secure and controlled manner. The provider needs to restrict data access based on specific roles within the consumer's Snowflake account and track data usage. Which of the following steps are NECESSARY to achieve these requirements?

A. Implement row-level security policies on the shared tables and views to filter data based on consumer roles. Share the tables and views in the Listing. Monitor usage through Snowflake's account usage views.
B. Implement a secure view with a 'WHERE clause that filters data based on the consumer's context and share the view in the Listing.
C. Create a Reader Account and share the data through that account, managing access directly.
D. Grant direct access to the underlying tables and views to the consumer's roles.

正解：A

解説：
Row-level security policies are critical for restricting data access based on consumer roles. Secure views can achieve similar outcomes, but row-level policies provides a more structured and scalable solution. Sharing the tables and views allows consumers to directly query the data, while the security policies enforce the access restrictions. Snowflake's account usage views provide the necessary tools for tracking data usage by consumers. Creating Reader accounts, and not using listings at all are valid approaches but don't make use of Snowflake Listings.

質問 # 126
You have a Snowflake stage named that points to an S3 bucket containing JSON log files. You want to create a directory table to track the files and their metadata'. The log files are continuously being added to the bucket. Which of the following sets of steps is the MOST efficient way to create and maintain an up-to-date directory table for this stage?

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

正解：B

解説：
Option D is the most efficient. While S3 event notifications (option B) can be faster, setting up and maintaining the event notification infrastructure and ensuring delivery can be complex. only refreshes at creation. There is no REFRESH_AUTOMATICALLY or 'AUTO REFRESH' clause. Scheduling a Snowflake Task provides a managed and relatively simple way to keep the directory table up-to-date. The refresh interval for task should be configured for optimal performance.

質問 # 127
You are designing a data governance strategy for a Snowflake data warehouse. You need to track data lineage for compliance purposes. Specifically, you need to identify all downstream tables that depend on a specific column in a source table. Which combination of Snowflake features and techniques would you use to achieve this goal effectively?

A. Use Snowflake's INFORMATION SCHEMA views (TABLES, COLUMNS) and regularly audit user query history to manually reconstruct the data lineage.
B. Use Snowflake's ACCOUNT USAGE views related to query history and object dependencies, combined with a custom script to recursively trace data lineage based on SQL operations (e.g., INSERT INTO ... SELECT).
C. Utilize Snowflake's data lineage feature in conjunction with object tagging. Tag relevant columns and tables, then query the lineage views to trace dependencies.
D. Rely solely on user documentation and training to ensure data lineage is properly documented and maintained. Implement strict naming conventions for tables and columns.
E. Implement a custom data lineage tracking system by parsing all SQL queries executed in the Snowflake environment and storing the dependencies in a separate metadata database.

正解：C

解説：
Snowflake's data lineage features provide a direct and integrated solution for tracking data dependencies. Object tagging enhances this by allowing you to identify and categorize sensitive data, making it easier to trace lineage for specific data elements. The other options are either manual (A, D), require significant custom development (C, E), or don't leverage Snowflake's built-in capabilities.

質問 # 128
You have a Snowflake table 'CUSTOMER DATA with a column 'EMAIL' containing customer email addresses. You need to classify this column as 'PII' using a tag named 'SENSITIVITY' and value 'CONFIDENTIAL'. Also, you want all queries accessing this 'EMAIL' column to be logged, with specific details about who accessed it and when. You already have appropriate roles and privileges to perform the required operations. Which of the following SQL statements, when executed in sequence, will achieve this goal, assuming appropriate logging mechanisms are already configured to read from the Snowflake ACCESS HISTORY view?

正解：B

解説：
The correct sequence of SQL statements is in Option D. First, the tag 'SENSITIVITY' needs to be created. Second, although not explicitly a 'tag value' object, you still need to create a SENSITIVITY tag object. This makes the tag value 'CONFIDENTIAL' available. Then, the tag is applied to the column using the 'ALTER TABLE MODIFY COLUMN ... SET TAG' command with the desired value ('CONFIDENTIAL'). Granting USAGE permissions to the 'data_steward' role (though not directly related to the tagging itself) allows that role to manage and view tag assignments, which is important for governance. Options A, B, C, and E are incorrect because they do not correctly create and assign the tag and its value or have some of the GRANT statement.
