질문 # 30
What best practice recommendations will help prevent timeouts when using the PUT command to load large data sets? (Select TWO).
정답：C,D
설명：
To avoid timeouts during large data uploads with the PUT command in Snowflake, it is recommended to:
Compress files before loading: Compressed files are smaller and upload faster, reducing the risk of timeouts.
Increase the PARALLEL option value: This option allows more simultaneous upload threads, improving upload speed and efficiency for large datasets.
Semi-structured file formats and table staging do not directly impact timeouts, while enabling overwrite does not prevent timeouts but rather controls overwriting of existing files.
질문 # 31
Use of which file function allows a user to share unstructured data from an internal stage with an external reporting tool that does not have access to Snowflake">
정답：D
설명：
The GET_PRESIGNED_URL function in Snowflake generates a pre-signed URL for a file in an internal stage. This URL can be shared with external tools or users who do not have direct access to Snowflake, allowing them to download the file.
Generate Pre-Signed URL:
SELECT GET_PRESIGNED_URL(@my_stage/file.txt);
Share the URL: The generated URL can be shared with external users or applications, enabling them to access the file directly.

질문 # 32
When a replication schedule is set, how does Snowflake manage refreshes for failover groups?
정답：B
설명：
The correct answer is B. Only one refresh will run at a time .
Failover groups can be refreshed on a schedule to replicate supported account objects and database objects to target accounts. Snowflake does not run overlapping refresh operations for the same failover group.
Why B is correct:
If a scheduled refresh is still running, Snowflake does not start another concurrent refresh for the same failover group. Refresh operations are managed so that only one refresh runs at a time.
Why the other options are incorrect:
A). Multiple refreshes for the same failover group do not run concurrently.
C). Refreshes still require the appropriate privileges and configured replication/failover group permissions.
D). A delayed or long-running refresh does not mean the next refresh is automatically canceled in the way stated. The key behavior is that refreshes do not overlap.
Official Snowflake documentation reference:
Snowflake documentation for replication and failover groups explains that scheduled refreshes are managed by Snowflake and that refresh operations do not run concurrently for the same group.
Reference: Snowflake Documentation - Replication and failover groups; Snowflake Documentation - Failover group refresh; SnowPro Core Study Guide - Snowflake Account and Resource Management.

질문 # 33
Which Snowflake table is an implicit object layered on a stage, where the stage can be either internal or external?
정답：B
설명：
A directory table in Snowflake is an implicit object layered on a stage, whether internal or external. It allows users to query the contents of a stage as if it were a table, providing metadata about the files stored in the stage, such as filenames, file sizes, and last modified timestamps.

질문 # 34
What is the only supported character set for loading and unloading data from all supported file formats?
정답：C
설명：
UTF-8 is the only supported character set for loading and unloading data from all supported file formats in Snowflake. UTF-8 is a widely used encoding that supports a large range of characters from various languages, making it suitable for internationalization and ensuring data compatibility across different systems and platforms.
