CKAD-Batch15-Part 2

Which of the following deployment strategies allows for continuous delivery with minimal risk by releasing updates to a small subset of users initially?

• Blue-green deployment

• Canary deployment

• Rolling deployment

• Feature toggle deployment

In a blue-green deployment strategy, what happens when a new version of the application is deployed to the "green" environment?

• Traffic automatically shifts from blue to green

• Both blue and green environments serve traffic simultaneously

• Traffic is shifted gradually from blue to green

• Only the green environment serves traffic

Which deployment strategy involves updating a small portion of servers at a time until all servers are updated?

• Canary deployment

• Blue-green deployment

• Rolling deployment

• Recreate deployment

What is the primary purpose of a readiness probe in Kubernetes?

• To determine if a container is ready to accept traffic

• To check the overall health of the cluster

• To monitor the resource usage of a container

• To perform automated rollbacks in case of failure

What is the purpose of a startup probe in Kubernetes?

• To monitor the startup time of containers

• To ensure that containers are started in a specific order

• To check if a container has started successfully

• To perform pre-start initialization tasks

Which type of probe in Kubernetes is used to detect when a container becomes unresponsive or deadlocked?

• Readiness probe

• Liveness probe

• Startup probe

• Health check probe

In a blue-green deployment, how does traffic routing typically occur between the blue and green environments?

• Through a load balancer

• Through DNS changes

• Through direct IP routing

• Through a reverse proxy

What is the primary purpose of an init container in Kubernetes?

• To store sensitive data securely

• To initialize and prepare the environment before the main container starts

• To scale the application horizontally

• To monitor the health of the main container

In Kubernetes, what is the main function of a sidecar container?

• To act as the primary application container

• To provide additional functionality or support to the main container

• To manage the Kubernetes cluster itself

• To isolate sensitive data within the pod

In Kubernetes, which of the following statements regarding taints is true?

• Taints are only applicable to worker nodes in a Kubernetes cluster.

• A pod with a toleration matching a node's taint will always be scheduled onto that node.

• Taints are only used to specify resource constraints for nodes.

• Taints and tolerations are primarily used for inter-pod communication within a cluster.
