質問 # 46
What is the name of the Docker container runtime?
正解：B
解説：
The name of the Docker container runtime is containerd, which is a daemon that manages the complete container lifecycle of its host system, from image transfer and storage to container execution and supervision to low-level storage to network attachments and beyond. Dockerd is the Docker daemon that acts as the primary user interface for Docker. Docker cl is not a valid name for any Docker component. Cri-o is another container runtime that implements the Kubernetes Container Runtime Interface (CRI) to enable using OCI (Open Container Initiative) compatible runtimes.
質問 # 47
You are asked to run a container in a Kubernetes environment.
What should you do to accomplish this task?
正解：A
解説：
To run a container in a Kubernetes environment, you should define a YAML manifest for the container and its resources. YAML manifests are used to define Kubernetes objects, such as pods or services. These manifests describe the desired state of the system.
質問 # 48
Which two statements are true regarding isolated namespaces in Juniper Cloud-Native Contrail Networking (CN2)? (Choose two.)
正解：A、D
解説：
In Juniper Cloud-Native Contrail Networking (CN2), isolated namespaces are used to isolate a pod from other pods without explicitly configuring a network policy. Pods in an isolated namespace can only communicate with pods in the same namespace. They cannot reach pods or services in other isolated or non-isolated namespaces.
質問 # 49
Which command would you use to see which VMs are running on your KVM device?
正解：D
解説：
KVM (Kernel-based Virtual Machine) is a popular open-source virtualization technology that allows you to run virtual machines (VMs) on Linux systems. The virsh command-line tool is used to manage KVM VMs. Let's analyze each option:
A . virt-install
Incorrect: The virt-install command is used to create and provision new virtual machines. It is not used to list running VMs.
B . virsh net-list
Incorrect: The virsh net-list command lists virtual networks configured in the KVM environment. It does not display information about running VMs.
C . virsh list
Correct: The virsh list command displays the status of virtual machines managed by the KVM hypervisor. By default, it shows only running VMs. You can use the --all flag to include stopped VMs in the output.
D . VBoxManage list runningvms
Incorrect: The VBoxManage command is used with Oracle VirtualBox, not KVM. It is unrelated to KVM virtualization.
Why virsh list?
Purpose-Built for KVM: virsh is the standard tool for managing KVM virtual machines, and virsh list is specifically designed to show the status of running VMs.
Simplicity: The command is straightforward and provides the required information without additional complexity.
JNCIA Cloud Reference:
The JNCIA-Cloud certification emphasizes understanding virtualization technologies, including KVM. Managing virtual machines using tools like virsh is a fundamental skill for operating virtualized environments.
For example, Juniper Contrail supports integration with KVM hypervisors, enabling the deployment and management of virtualized network functions (VNFs). Proficiency with KVM tools ensures efficient management of virtualized infrastructure.

質問 # 50
Which OpenStack service displays server details of the compute node?
正解：B
解説：
OpenStack provides various services to manage cloud infrastructure resources, including compute nodes and virtual machines (VMs). Let's analyze each option:
A . Keystone
Incorrect: Keystone is the OpenStack identity service responsible for authentication and authorization. It does not display server details of compute nodes.
B . Neutron
Incorrect: Neutron is the OpenStack networking service that manages virtual networks, routers, and IP addresses. It is unrelated to displaying server details of compute nodes.
C . Cinder
Incorrect: Cinder is the OpenStack block storage service that provides persistent storage volumes for VMs. It does not display server details of compute nodes.
D . Nova
Correct: Nova is the OpenStack compute service responsible for managing the lifecycle of virtual machines, including provisioning, scheduling, and monitoring. It also provides detailed information about compute nodes and VMs, such as CPU, memory, and disk usage.
Why Nova?
Compute Node Management: Nova manages compute nodes and provides APIs to retrieve server details, including resource utilization and VM status.
Integration with CLI/REST APIs: Commands like openstack server show or nova hypervisor-show can be used to display compute node and VM details.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers OpenStack services, including Nova, as part of its cloud infrastructure curriculum. Understanding Nova's role in managing compute resources is essential for operating OpenStack environments.
For example, Juniper Contrail integrates with OpenStack Nova to provide advanced networking and security features for compute nodes and VMs.
