質問 # 274
Which SQL command can be used to see the CREATE definition of a masking policy?
正解：B
解説：
The SQL command GET_DDL can be used to retrieve the CREATE definition of a masking policy in Snowflake.This command generates the DDL statement required to recreate the masking policy
質問 # 275
What are potential impacts of storing non-native values like dates and timestamps in a variant column in Snowflake?
正解：D
解説：
Storing non-native values, such as dates and timestamps, in a VARIANT column in Snowflake can lead to slower query performance and increased storage consumption. VARIANT is a semi-structured data type that allows storing JSON, AVRO, ORC, Parquet, or XML data in a single column. When non-native data types are stored as VARIANT, Snowflake must perform implicit conversion to process these values, which can slow down query execution. Additionally, because the VARIANT data type is designed to accommodate a wide variety of data formats, it often requires more storage space compared to storing data in native, strongly-typed columns that are optimized for specific data types.
The performance impact arises from the need to parse and interpret the semi-structured data on the fly during query execution, as opposed to directly accessing and operating on optimally stored data in its native format.
Furthermore, the increased storage consumption is a result of the overhead associated with storing data in a format that is less space-efficient than the native formats optimized for specific types of data.

質問 # 276
A user has unloaded data from a Snowflake table to an external stage.
Which command can be used to verify if data has been uploaded to the external stage named my_stage?
正解：A
解説：
The list @my_stage command in Snowflake can be used to verify if data has been uploaded to an external stage namedmy_stage.This command provides a list of files that are present in the specified stage2.
質問 # 277
If a virtual warehouse runs for 61 seconds, shut down, and then restart and runs for 30 seconds, for how many seconds is it billed?
正解：B
解説：
Snowflake bills virtual warehouse usage in one-minute increments, rounding up to the nearest minute for any partial minute of compute time used. If a virtual warehouse runs for 61 seconds and then, after being shut down, restarts and runs for an additional 30 seconds, the total time billed would be 120 seconds or 2 minutes.
The first 61 seconds are rounded up to 2 minutes, and the subsequent 30 seconds are within a new minute, which is also rounded up to the nearest minute.
