You are deploying a new version of a critical web application. You want to route 5% of user traffic to the new version to monitor for errors before rolling it out to 100%. If errors spike, you want to instantly revert to the old version. Which THREE GCP services/features can facilitate this Canary deployment strategy? (Select THREE)

Canary deployments require precise, percentage-based traffic routing. Cloud Run and App Engine both have native, built-in traffic splitting capabilities between revisions/versions. For applications on Compute Engine or GKE, the Global External HTTP(S) Load Balancer supports advanced traffic management, including weight-based routing to different backend services. DNS is not suitable due to TTL caching preventing instant rollbacks.
