최신 SnowPro Core COF-C03 무료샘플문제 (Q194-Q199):

질문 # 194
What are advantages clones have over tables created with CREATE TABLE AS SELECT statement? (Choose two.)

A. The clone saves space by not duplicating storage.
B. The clone is created almost instantly.
C. The clone will have time travel history from the original table.
D. The clone has better query performance.
E. The clone always stays in sync with the original table.

정답：A,B

설명：
Clones in Snowflake have the advantage of being created almost instantly and saving space by not duplicating storage.This is due to Snowflake's zero-copy cloning feature, which allows for the creation of object clones without the additional storage costs typically associated with data duplication23. Clones are independent of the original table and do not stay in sync with it, nor do they inherently have better query performance.However, they do inherit the time travel history from the original table at the time of cloning

질문 # 195
Which table function will identify data that was loaded using COPY INTO <table> statements and also identify data loaded using Snowpipe?

A. DATA_TRANSFER_HISTORY
B. VALIDATE_PIPE_LOAD
C. PIPE_USAGE_HISTORY
D. COPY_HISTORY

정답：D

설명：
The COPY_HISTORY table function in Snowflake is used to track data loading activities, including both manual COPY INTO <table> commands and automated data loading through Snowpipe. This function provides visibility into load operations, making it valuable for monitoring data ingestion, ensuring data integrity, and troubleshooting loading processes.

질문 # 196
Which default warehouse configuration has the highest precedence whenever a new session is created by a user?

A. Default warehouse in the configuration file of the client utilities
B. Default warehouse of the role assigned to the user
C. Default warehouse tor the user
D. Default warehouse specified on a CLI or in drivers/connectors parameters

정답：B

질문 # 197
The first user assigned to a new account, ACCOUNTADMIN, should create at least one additional user with which administrative privilege?

A. USERADMIN
B. SYSADMIN
C. PUBLIC
D. ORGADMIN

정답：A

질문 # 198
How does a Snowflake user extract the URL of a directory table on an external stage for further transformation?

A. Use the GET_STAGE_LOCATION function.
B. Use the DESCRIBE STAGE command.
C. Use the SHOW STAGES command.
D. Use the GET_ABSOLUTE_PATH function.

정답：D

설명：
To extract the URL of a directory table on an external stage for further transformation in Snowflake, the GET_ABSOLUTE_PATH function can be used. This function returns the full path of a file or directory within a specified stage, enabling users to dynamically construct URLs for accessing or processing data stored in external stages.
