GCP Professional Cloud Security Engineer Practice Question

Your company operates a Java service in its on-premises data center that invokes Google Cloud Translation API with an API key embedded in application code. Security engineers want to reduce the blast radius if the key is leaked: the key must remain usable only from the data-center's two static egress IP addresses and must never work against any Google APIs except Cloud Translation. Which configuration best satisfies these requirements while preserving current functionality?

  • Keep the key unrestricted but set per-user daily quota to zero for every Google API except Cloud Translation.

  • Replace the API key with OAuth 2.0 service-account authentication so requests use signed JWTs instead of an API key.

  • Edit the existing API key to add an IP address application restriction for the two egress IPs and enable an API restriction that permits only the Cloud Translation API.

  • Place Cloud Translation API and the on-premises project inside a VPC Service Controls service perimeter that blocks egress to all other Google APIs.
