質問 # 20
Which container runtime engine is used by default in OpenShift?
正解:A
解説:
The default container runtime engine used by OpenShift is cri-o. CRI-O is an open source, community-driven container engine. Its primary goal is to replace the Docker service as the container engine for Kubernetes implementations, such as OpenShift Container Platform.
質問 # 21
Which technology is used to run VMs in an OpenShift cluster?
正解:A
解説:
OpenShift is a Kubernetes-based container platform that supports both containerized and virtualized workloads. Let's analyze each option:
A . ESXi
Incorrect: ESXi is VMware's hypervisor for running virtual machines. While it is widely used in traditional virtualization environments, it is not integrated into OpenShift.
B . OpenStack
Incorrect: OpenStack is an open-source cloud computing platform used for managing infrastructure resources (e.g., compute, storage, networking). It is unrelated to running VMs in an OpenShift cluster.
C . Hyper-V
Incorrect: Hyper-V is Microsoft's hypervisor for running virtual machines. Like ESXi, it is not integrated into OpenShift.
D . KubeVirt
Correct: KubeVirt is the technology used to run virtual machines in an OpenShift cluster. It extends Kubernetes to support VM workloads alongside containers, enabling hybrid workload management.
Why KubeVirt?
Integration with OpenShift: KubeVirt is specifically designed to run VMs in Kubernetes-based environments like OpenShift.
Hybrid Workload Support: It allows organizations to manage both containers and VMs using the same Kubernetes APIs and tools.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers OpenShift and its integration with Kubernetes extensions like KubeVirt. Understanding how to run VMs in OpenShift is essential for managing hybrid workloads in cloud-native environments.
For example, Juniper Contrail integrates with OpenShift and KubeVirt to provide networking and security for hybrid workloads.

質問 # 22
What is the role of overlay tunnels in an overlay software-defined networking (SDN) solution?
正解:D
解説:
In an overlay software-defined networking (SDN) solution, overlay tunnels play a critical role in abstracting the underlying physical network (underlay) from the virtualized network (overlay). Let's analyze each option:
A . The overlay tunnels provide optimization of traffic for performance and resilience.
Incorrect: While overlay tunnels can contribute to traffic optimization indirectly, their primary role is not performance or resilience. These aspects are typically handled by SDN controllers or other network optimization tools.
B . The overlay tunnels provide load balancing and scale out for applications.
Incorrect: Load balancing and scaling are functions of application-level services or SDN controllers, not the overlay tunnels themselves. Overlay tunnels focus on encapsulating traffic rather than managing application workloads.
C . The overlay tunnels provide microsegmentation for workloads.
Incorrect: Microsegmentation is achieved through policies and security rules applied at the overlay network level, not directly by the tunnels themselves. Overlay tunnels enable the transport of segmented traffic but do not enforce segmentation.
D . The overlay tunnels abstract the underlay network topology.
Correct: Overlay tunnels encapsulate traffic between endpoints (e.g., VMs, containers) and hide the complexity of the underlay network. This abstraction allows the overlay network to operate independently of the physical network topology, enabling flexibility and scalability.
Why This Answer?
Abstraction of Underlay: Overlay tunnels use encapsulation protocols like VXLAN, GRE, or MPLS to create virtualized networks that are decoupled from the physical infrastructure. This abstraction simplifies network management and enables advanced features like multi-tenancy and mobility.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers overlay and underlay networks as part of its SDN curriculum. Understanding the role of overlay tunnels is essential for designing and managing virtualized networks in cloud environments.
For example, Juniper Contrail uses overlay tunnels to provide connectivity between virtual machines (VMs) and containers, abstracting the physical network and enabling seamless communication across distributed environments.

Click the Exhibit button.
Referring to the exhibit, which port number would external users use to access the WEB application?
正解:D
解説:
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?
A . 80: Port 80 is commonly used for HTTP traffic, but it is not specified in the YAML file. The service does not expose port 80 externally.
B . 8080: Port 8080 is the internal port used within the Kubernetes cluster. It is not the port exposed to external users.
D . 5000: Port 5000 is the target port where the application runs inside the pod. It is not directly accessible to external users.
Why 31000?
NodePort Service Type: The NodePort service type exposes the application on a high-numbered port (default range: 30000-32767) on each node in the cluster.
External Accessibility: External users must use the nodePort value (31000) along with the node's IP address to access the WEB application.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers Kubernetes networking concepts, including service types like ClusterIP, NodePort, and LoadBalancer. Understanding how NodePort services work is essential for exposing applications to external users in Kubernetes environments.
For example, Juniper Contrail integrates with Kubernetes to provide advanced networking features, such as load balancing and network segmentation, for services like the one described in the exhibit.

質問 # 24
You are asked to provision a bare-metal server using OpenStack.
Which service is required to satisfy this requirement?
正解:A
解説:
OpenStack is an open-source cloud computing platform that provides various services for managing compute, storage, and networking resources. To provision a bare-metal server in OpenStack, the Ironic service is required. Let's analyze each option:
A . Ironic
Correct: OpenStack Ironic is a bare-metal provisioning service that allows you to manage and provision physical servers as if they were virtual machines. It automates tasks such as hardware discovery, configuration, and deployment of operating systems on bare-metal servers.
B . Zun
Incorrect: OpenStack Zun is a container service that manages the lifecycle of containers. It is unrelated to bare-metal provisioning.
C . Trove
Incorrect: OpenStack Trove is a Database as a Service (DBaaS) solution that provides managed database instances. It does not handle bare-metal provisioning.
D . Magnum
Incorrect: OpenStack Magnum is a container orchestration service that supports Kubernetes, Docker Swarm, and other container orchestration engines. It is focused on containerized workloads, not bare-metal servers.
Why Ironic?
Purpose-Built for Bare-Metal: Ironic is specifically designed to provision and manage bare-metal servers, making it the correct choice for this requirement.
Automation: Ironic automates the entire bare-metal provisioning process, including hardware discovery, configuration, and OS deployment.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers OpenStack as part of its cloud infrastructure curriculum. Understanding OpenStack services like Ironic is essential for managing bare-metal and virtualized environments in cloud deployments.
For example, Juniper Contrail integrates with OpenStack to provide networking and security for both virtualized and bare-metal workloads. Proficiency with OpenStack services ensures efficient management of diverse cloud resources.
