Your company is using HTTPS requests to trigger a public Cloud Run-hosted service accessible at the https://booking-engine-abcdef.a.run.app URL. You need to give developers the ability to test the latest revisions of the service before the service is exposed to customers. What should you do?

A. Run the gcloud run deploy booking-engine --no-traffic --tag dev command. Use the https://dev--booking-engine-abcdef.a.run.app URL for testing. B. Run the gcloud run services update-traffic booking-engine --to-revisions LATEST=1 command. Use the https://booking-engine-abcdef.a.run.app URL for testing. C. Pass the curl –H “Authorization:Bearer $(gcloud auth print-identity-token)” auth token. Use the https://booking-engine-abcdef.a.run.app URL to test privately. D. Grant the roles/run.invoker role to the developers testing the booking-engine service. Use the https://booking-engine-abcdef.private.run.app URL for testing.
