NEW QUESTION # 443
Cloning is being used to create a development environment. Will storage be impacted when cloned tables are modified in a development environment?
Answer: D
Explanation:
Zero-copy cloning initially shares micro-partitions between the source object and the clone. However, when data is modified in either the original or cloned object, Snowflake creates new micro-partitions for the changed data. Those modified micro-partitions consume additional storage.
Reference: Snowflake Documentation - Zero-copy cloning; Micro-partitions; Storage impact of cloned objects.
NEW QUESTION # 444
Which of the following objects can be shared through secure data sharing?
Answer: D
Explanation:
Secure data sharing in Snowflake allows users to share various objects between Snowflake accounts without physically copying the data, thus not consuming additional storage. Among the options provided, external tables can be shared through secure data sharing. External tables are used to query data directly from files in a stage without loading the data into Snowflake tables, making them suitable for sharing across different Snowflake accounts.

NEW QUESTION # 445
The following settings are configured:
THE MIN_DATA_RETENTION_TIME_IN_DAYS is set to 5 at the account level.
THE DATA_RETENTION_TIME_IN_DAYS is set to 2 at the object level.
For how many days will the data be retained at the object level?
Answer: B
Explanation:
The settings shown in the image indicate that the data retention time in days is configured at two different levels: the account level and the object level. At the account level, theMIN_DATA_RETENTION_TIME_IN_DAYSis set to 5 days, and at the object level, theDATA_RETENTION_TIME_IN_DAYSis set to 2 days. Since the object level setting has a lower value, it takes precedence over the account level setting for the specific object. Therefore, the data will be retained for
2 days at the object level.

NEW QUESTION # 446
A user has unloaded data from Snowflake to a stage
Which SQL command should be used to validate which data was loaded into the stage?
Answer: A
Explanation:
Thelistcommand in Snowflake is used to validate and display the list of files in a specified stage. When a user has unloaded data to a stage, running the list @file__stage command will show all the files that have been uploaded to that stage, allowing the user to verify the data that was unloaded.

NEW QUESTION # 447
Which table type exists only within the session it was created and is only visible to the user who created it?
Answer: B
Explanation:
The correct answer is D. Temporary .
A temporary table exists only for the duration of the session in which it was created. It is only visible to the user session that created it and is automatically dropped when the session ends.
Why D is correct:
Temporary tables are useful for session-specific intermediate data. They do not persist beyond the session and are not visible to other users or sessions.
Example:
CREATE TEMPORARY TABLE temp_sales AS
SELECT *
FROM sales
WHERE sales_date = CURRENT_DATE;
Why the other options are incorrect:
A). Hybrid tables are optimized for transactional workloads and are not session-only objects.
B). Dynamic tables are used for declarative, automated data transformation and are persistent database objects.
C). Transient tables persist until explicitly dropped and are visible according to granted privileges. They do not have Fail-safe, but they are not session-only.
Official Snowflake documentation reference:
Snowflake documentation describes temporary tables as existing only within the session in which they are created and being dropped automatically at the end of the session.
