COF-C03 Data Loading, Unloading, and Connectivity Practice Question
Which Snowflake feature allows for secure, direct communication between a customer's virtual private cloud (VPC) and the Snowflake service without using the public internet?
⚠ Common exam trap
Candidates often confuse Snowflake Private Link with general network policies or external stages, missing its specific VPC connectivity purpose.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Snowflake Private Link
For organizations with strict security and compliance requirements, avoiding the public internet for data transit is essential. Snowflake supports private connectivity options on major cloud providers to ensure that data remains within the cloud provider's network backbone, significantly reducing the attack surface for potential data interception.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Snowflake Data Exchange
Why it's wrong here
The Data Exchange is a platform for sharing data between different Snowflake accounts and organizations. While it is secure, it is a data collaboration feature and not a networking technology used to establish private connectivity between a VPC and the Snowflake service environment.
- ✓
Snowflake Private Link
Why this is correct
Snowflake Private Link (based on AWS PrivateLink or Azure Private Link) provides private connectivity to Snowflake by ensuring that all traffic stays within the cloud provider's network. This eliminates exposure to the public internet and simplifies the network architecture for highly regulated industries like finance or healthcare.
- ✗
SnowSQL Proxy Configuration
Why it's wrong here
Configuring a proxy in SnowSQL allows the CLI tool to route its traffic through an internal corporate proxy server. While this is a common network configuration, it still typically involves the traffic eventually crossing the public internet unless the proxy itself is part of a private link setup.
- ✗
Network Policy Whitelisting
Why it's wrong here
Network policies are used to restrict access to Snowflake based on IP addresses, but they do not create a private path for the data. The traffic still travels over the public internet; the policy simply acts as a gatekeeper that rejects connections from unauthorized IP ranges.
