Practice questionDomain 2: Building and implementing CI/CD pipelines, including continuous testing, for application, infrastructure, and machine learning workloads

A retailer deploys a payment service to GKE through Cloud Deploy. Compliance now requires that production run only images built by the company's Cloud Build pipeline and checked for critical vulnerabilities. Developers must not be able to bypass this. What should you implement?
