Snowflake applies egress charges in the case of database replication when data is transferred out of a Snowflake region to another region or cloud provider. This is because the data transfer incurs costs associated with moving data across different networks. Egress charges are not applied for data sharing within the same region, query result retrieval, or loading data into Snowflake, as these actions do not involve data transfer across regions.

The correct answer is B. Snowflake CLI is primarily used for managing workloads and applications, while SnowSQL is used for executing operations .
SnowSQL is Snowflake's command-line client that is primarily used to connect to Snowflake and execute SQL statements. It is commonly used for SQL operations, including running queries, loading data, unloading data, and executing scripts.
Snowflake CLI is a broader command-line tool designed for managing Snowflake workloads and application development workflows. It supports tasks related to Snowflake Native Apps, Snowpark, Streamlit, stages, tasks, and other development or deployment activities.
Why B is correct:
Snowflake CLI is more focused on managing Snowflake workloads, projects, and applications. SnowSQL is primarily used as a SQL command-line client to execute SQL operations against Snowflake.
Why the other options are incorrect:
A). This reverses the primary purposes of the tools. SnowSQL is not mainly for managing workloads and applications.
C). SnowSQL is not limited to DDL, and Snowflake CLI is not limited to DML.
D). Snowflake CLI is not limited to query execution, and SnowSQL is not a Python package management tool.
Official Snowflake documentation reference:
Snowflake documentation describes SnowSQL as the command-line client for connecting to Snowflake and executing SQL queries. Snowflake CLI is described as a command-line tool for developer workflows and managing Snowflake workloads and applications.
