My Answer B:
Creating a Cloud Run endpoint as a proxy to the data allows you to control access to the internal data through an API endpoint. By using Identity and Access Management (IAM) authentication, you can enforce strict access controls, ensuring that only authorized entities (such as your training job) can access the data. This approach helps mitigate the risk of data exfiltration by providing a secure and controlled access point to the internal data.
- Option A: may help control access within Google Cloud Platform services, but it does not directly address securing access to the internal data through an API endpoint.
- Option C: is more about network configurations and does not provide a solution for securely accessing the internal data through an API endpoint.
- Option D: involves transferring the data to a Cloud Storage bucket, which might introduce additional security risks during the data transfer process.
