When considering OpenShift and Kubernetes, what are two unique resources of OpenShift? (Choose two.)
- A . routes
- B . build
- C . ingress
- D . services
A, B
Explanation:
OpenShift extends Kubernetes by introducing additional resources and abstractions to simplify application development and deployment.
Let’s analyze each option:
Which container runtime engine is used by default in OpenShift?
- A . containerd
- B . cri-o
- C . Docker
- D . runC
B
Explanation:
OpenShift uses a container runtime engine to manage and run containers within its Kubernetes-based environment.
Let’s analyze each option:
Click the Exhibit button.
Referring to the exhibit, which port number would external users use to access the WEB application?
- A . 80
- B . 8080
- C . 31000
- D . 5000
C
Explanation:
The YAML file provided in the exhibit defines a Kubernetes Service object of type NodePort. Let’s break down the key components of the configuration and analyze how external users access the WEB application:
Key Fields in the YAML File:
type: NodePort:
This specifies that the service is exposed on a static port on each node in the cluster. External users can access the service using the node’s IP address and the assigned nodePort.
port: 8080:
This is the port on which the service is exposed internally within the Kubernetes cluster. Other services or pods within the cluster can communicate with this service using port 8080.
targetPort: 5000:
This is the port on which the actual application (WEB application) is running inside the pod. The service forwards traffic from port: 8080 to targetPort: 5000.
nodePort: 31000:
This is the port on the node (host machine) where the service is exposed externally. External users will use this port to access the WEB application.
How External Users Access the WEB Application:
External users access the WEB application using the node’s IP address and the nodePort value (31000).
The Kubernetes service listens on this port and forwards incoming traffic to the appropriate pods running the WEB application.
