Practice Free JN0-214 Exam Online Questions
Which term identifies to which network a virtual machine interface is connected?
- A . virtual network ID
- B . machine access control (MAC)
- C . Virtual Extensible LAN
- D . virtual tunnel endpoint (VTEP)
A
Explanation:
In cloud environments, virtual machines (VMs) connect to virtual networks to enable communication. Identifying the network to which a VM interface is connected is essential for proper configuration and isolation.

Let’s analyze each option:
You have built a Kubernetes environment offering virtual machine hosting using KubeVirt.
Which type of service have you created in this scenario?
- A . Software as a Service (Saa
- B . Platform as a Service (Paa
- C . Infrastructure as a Service (laaS)
- D . Bare Metal as a Service (BMaaS)
C
Explanation:
Kubernetes combined with KubeVirt enables the hosting of virtual machines (VMs) alongside containerized workloads. This setup aligns with a specific cloud service model.
Let’s analyze each option:
Which component of Kubernetes runs on each node maintaining network rules?
- A . container runtime
- B . kube-proxy
- C . kubelet
- D . kube controller
B
Explanation:
Kubernetes components work together to ensure seamless communication and network functionality within the cluster.
Let’s analyze each option:
Your organization has legacy virtual machine workloads that need to be managed within a Kubernetes deployment.
Which Kubernetes add-on would be used to satisfy this requirement?
- A . ADOT
- B . Canal
- C . KubeVirt
- D . Romana
C
Explanation:
Kubernetes is designed primarily for managing containerized workloads, but it can also support legacy virtual machine (VM) workloads through specific add-ons.
Let’s analyze each option:
Which two statements about Kubernetes are correct? (Choose two.)
- A . Kubernetes is compatible with the container open container runtime.
- B . Kubernetes requires the Docker daemon to run Docker containers.
- C . A container is the smallest unit of computing that you can manage with Kubernetes.
- D . A Kubernetes cluster must contain at least one control plane node.
A, C
Explanation:
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications.
Let’s analyze each statement:
Which statement about software-defined networking is true?
- A . It must manage networks through the use of containers and repositories.
- B . It manages networks by separating the data forwarding plane from the control plane.
- C . It applies security policies individually to each separate node.
- D . It manages networks by merging the data forwarding plane with the control plane.
B
Explanation:
Software-Defined Networking (SDN) is a revolutionary approach to network management that separates the control plane from the data (forwarding) plane.
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.
Why Not Other Options?
You want to create a template that defines the CPU, RAM, and disk space properties that a VM will use when instantiated.
In this scenario, which OpenStack object should you create?
- A . role
- B . Image
- C . project
- D . flavor
D
Explanation:
In OpenStack, a flavor defines the compute, memory, and storage properties of a virtual machine (VM) instance.
