Q54 Single choice

You have an application that reads data from a Pub/Sub topic. During local development, you authenticated using your personal credentials to test the application. You now want to deploy the application to Vertex AI and have created a new service account to be used as the application's identity. You need to ensure that the deployed application can still access the Pub/Sub topic.

What should you do?

A
Grant the relevant IAM roles to the service account used as your agent identity.
B
Generate a JSON private key for the service account, and upload the key as Vertex AI metadata.
C
Extract your access token by using the gcloud auth print-access-token command, and store it with the application.
D
Create a secret in Secret Manager to store your personal credentials, and configure the application's authentication code to use this secret.
