hello @Vetrivel,

Serverless compute resources run in the serverless compute plane, which is managed by Azure Databricks. For more details on the network and architecture, see Serverless compute plane networking.

TL;DR: you need to use NCC to be able to access your resources.

Let me know if this helps.
