Answer: SnowCD

The question asks about a Snowflake native tool specifically designed for diagnosing and troubleshooting network connections. SnowCD (Snowflake Connectivity Diagnostic Tool) is explicitly built for this purpose - it tests network connectivity between a client machine and Snowflake services, checking DNS resolution, network latency, and firewall configurations. The community discussion strongly supports this with 83% of users selecting D (SnowCD) and multiple comments confirming this is the tool's defined purpose, with references to official Snowflake documentation. SnowSQL is a command-line client for executing SQL, Snowflake Python connector is for application connectivity, and Snowsight is the web interface - none of these are dedicated network diagnostic tools.
