D!!! for sure! The RollingUpdate deployment strategy is a Kubernetes-native method that supports zero-downtime updates by gradually replacing old pods with new ones, ensuring continuous availability during the deployment process. Other strategies that also achieve zero-downtime include Blue-Green Deployment, which uses two identical environments to switch traffic over, and Canary Releases, where updates are first rolled out to a small subset of users.
