NEW QUESTION # 73
You are running a Kubernetes cluster with a single node. You need to ensure that your application remains available even if the node fails. Which Kubernetes feature should you use?

A. Pod Disruption Budgets
B. High availability
C. Horizontal Pod Autoscaling
D. Rolling updates
E. Node affinity

Answer: B

Explanation:
High availability in Kubernetes is achieved by running your cluster on multiple nodes. This ensures that your application remains available even if one node fails, as the workloads can be automatically moved to other healthy nodes.

NEW QUESTION # 74
You are using ArgoCD to manage your Kubernetes cluster with GitOps. How can you configure ArgoCD to automatically update the cluster when a new image tag is pushed to a container registry?

A. Use the *imagePullSecrets• field in the deployment configuration to provide the registry credentials to ArgoCD.
B. Use the *imagePullPolicys field in the container definition to automatically pull the latest image.
C. Use the *imagelJpdateStrategy' field in the deployment configuration to define the update policy.
D. Configure ArgoCD to use a Cron job that regularly checks for new image tags.
E. Configure ArgoCD to use a webhook that triggers an update whenever a new image tag is pushed.

Answer: E

Explanation:
ArgoCD can be configured to use webhooks, which are HTTP callbacks triggered by events like image pushes to container registries. This allows ArgoCD to automatically update the cluster whenever a new image tag is pushed, ensuring your deployments are always using the latest image versions.
