NEW QUESTION # 988
What is the MINIMUM role required to set the value for the parameter ENABLE_ACCOUNT_DATABASE_REPLICATION?
Answer: B
Explanation:
The ENABLE_ACCOUNT_DATABASE_REPLICATION parameter is a critical setting in Snowflake that allows or restricts the replication of databases across Snowflake accounts. Given the significant impact of this parameter on data management and security, only the ACCOUNTADMIN role has the minimum required privileges to set or modify it. This ensures that only users with the highest level of access and responsibility within the Snowflake environment can control database replication settings, maintaining strict governance and security standards.
Reference: Snowflake Documentation on Database Replication
NEW QUESTION # 989
How does Snowflake allow a data provider with an Azure account in central Canada to share data with a data consumer on AWS in Australia?
Answer: B
Explanation:
Snowflake allows data providers to share data with consumers across different cloud platforms and regions through database replication. The data provider must replicate the database to a secondary account in the target region or cloud platform within the same organization, and then create a share to the data consumer's account. This process ensures that the data is available in the consumer's region and on their cloud platform, facilitating seamless data sharing.

NEW QUESTION # 990
What should be used when creating a CSV file format where the columns are wrapped by single quotes or double quotes?
Answer: A
Explanation:
When creating a CSV file format in Snowflake and the requirement is to wrap columns by single quotes or double quotes, the FIELD_OPTIONALLY_ENCLOSED_BY parameter should be used in the file format specification. This parameter allows you to define a character (either a single quote or a double quote) that can optionally enclose each field in the CSV file, providing flexibility in handling fields that contain special characters or delimiters as part of their data.

NEW QUESTION # 991
Where can files be created when the data is going to be unloaded from Snowflake using a copy into
<location> command? (Select TWO).
Answer: B,C

* C. External Stage: These are external storage locations (e.g., AWS S3, Azure Blob Storage, or Google Cloud Storage) linked to Snowflake using a stage definition.
Why Other Options Are Incorrect:
* B. SFTP Location: Snowflake does not directly support SFTP as a storage location.
* D. Network Share Folder: Network shares are not supported by Snowflake for data unloading.
* E. Local Disk: Snowflake does not allow unloading data directly to a local disk.

NEW QUESTION # 992
A column named "Data" contains VARIANT data and stores values as follows:
How will Snowflake extract the employee's name from the column data?
Answer: B
Explanation:
In Snowflake, to extract a specific value from a VARIANT column, you use the column name followed by a colon and then the key. The keys are case-sensitive. Therefore, to extract the employee's name from the
"Data" column, the correct syntax is data:employee.name.
