Correct answer: Sync Waves

Sync Waves allow you to order how manifests are applied by annotating them with 'argocd.argoproj.io/sync-wave'. Lower values are applied first. Argo CD waits for the health status of the previous wave before proceeding to the next.

Correct answer: Define the 'replicas' field directly in the 'kustomization.yaml' file.

Kustomize provides a top-level 'replicas' list in kustomization.yaml that specifically targets resources by name and updates their replica count. This is cleaner and more explicit than generic patching for this specific use case.

Correct answer: Define a 'podTemplate' with a container specification that includes 'resourceRequest' and 'resourceLimit'.

In the Kubernetes plugin for Jenkins (used in OpenShift), you define the agent environment using `podTemplate`. Within this template, you specify the container specs, including CPU and memory requests and limits.

Correct answer: helm.sh/resource-policy: keep

The annotation `helm.sh/resource-policy: keep` instructs Helm to skip deleting or modifying this resource during an upgrade or uninstall operation. It 'abandons' the resource management while leaving it in the cluster.

Correct answer: You require zero-downtime cutover between two distinct environments (active and idle) by switching the Route destination.

Blue/Green deployment involves running two identical environments. One is live (Blue) and one is idle (Green). The cutover is instantaneous and achieved by updating the Router configuration to point to the Green service instead of Blue.

Correct answers: The List generator allows you to manually define a fixed list of clusters or configuration values to iterate over.; The Cluster generator automatically discovers clusters registered in Argo CD and deploys applications to them.

The List generator is one of the simplest generators, allowing explicit definition of parameters (like cluster URL and cluster name) to create Applications.

The Cluster generator queries the Argo CD cluster secrets and generates parameters for each registered cluster, enabling automatic multi-cluster deployments.
