Question: 5

Which two statements are correct about Kubernetes resources? (Choose two.)

AA ClusterIP type service can only be accessed within a Kubernetes cluster.

BA daemonSet ensures that a replica of a pod is running on all nodes.

CA deploymentConfig is a Kubernetes resource.

DNodePort service exposes the service externally by using a cloud provider load balancer.

DNodePort service exposes the service externally by using a cloud provider load balancer.
Incorrect:
A NodePort service exposes the service on a static port on each node in the cluster, allowing external access via the node's IP address and the assigned port. However, it does not use a cloud provider load balancer. The LoadBalancer service type is the one that leverages cloud provider load balancers for external access.
Why These Statements?
ClusterIP: Ensures internal-only communication, making it suitable for backend services that do not need external exposure.
DaemonSet: Guarantees that a specific pod runs on all nodes, ensuring consistent functionality across the cluster.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers Kubernetes resources and their functionalities, including services, DaemonSets, and Deployments. Understanding these concepts is essential for managing Kubernetes clusters effectively.
For example, Juniper Contrail integrates with Kubernetes to provide advanced networking features for services and DaemonSets, ensuring seamless operation of distributed applications.
