Juniper Cloud, Associate (JNCIA-Cloud) Sample Questions (Q23-Q28):

NEW QUESTION # 23
What is the name of the Docker container runtime?

A. docker cl
B. containerd
C. dockerd
D. cri-o

Answer: B

Explanation:
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.

NEW QUESTION # 24
Your company has a Web app hosted in Kubernetes with a fluctuating number of pods.
In this scenario, which Kubernetes service type would provide equal access to all nodes using a single URL?

A. LoadBalancer
B. NodePort
C. ExternalName
D. ClusterIP

Answer: A

Explanation:
The LoadBalancer service type in Kubernetes exposes the service externally using a cloud provider's load balancer. NodePort and ClusterIP services, to which the external load balancer routes, are automatically created.

NEW QUESTION # 25
Which operating system must be used for control plane machines in Red Hat OpenShift?

A. Red Hat Enterprise Linux
B. Red Hat CoreOS
C. Centos
D. Ubuntu

Answer: B

Explanation:
Red Hat OpenShift requires specific operating systems for its control plane machines to ensure stability, security, and compatibility. Let's analyze each option:
A . Ubuntu
Incorrect:
While Ubuntu is a popular Linux distribution, it is not the recommended operating system for OpenShift control plane machines. OpenShift relies on Red Hat-specific operating systems for its infrastructure.
B . Red Hat Enterprise Linux
Incorrect:
Red Hat Enterprise Linux (RHEL) is commonly used for worker nodes in OpenShift clusters. However, control plane machines require a more specialized operating system optimized for Kubernetes workloads.
C . Red Hat CoreOS
Correct:
Red Hat CoreOS is the default operating system for OpenShift control plane machines. It is a lightweight, immutable operating system specifically designed for running containerized workloads in Kubernetes environments. CoreOS ensures consistency, security, and automatic updates.
D . CentOS
Incorrect:
CentOS is a community-supported Linux distribution based on RHEL. While it can be used in some Kubernetes environments, it is not supported for OpenShift control plane machines.
Why Red Hat CoreOS?
Immutable Infrastructure: CoreOS is designed to be immutable, meaning updates are applied automatically and consistently across the cluster.
Optimized for Kubernetes: CoreOS is tailored for Kubernetes workloads, providing a secure and reliable foundation for OpenShift control plane components.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers OpenShift architecture, including the operating systems used for control plane and worker nodes. Understanding the role of Red Hat CoreOS is essential for deploying and managing OpenShift clusters effectively.
For example, Juniper Contrail integrates with OpenShift to provide advanced networking features, relying on CoreOS for secure and efficient operation of control plane components.

NEW QUESTION # 26
Which command would you use to see which VMs are running on your KVM device?

A. VBoxManage list runningvms
B. virsh list
C. virsh net-list
D. virt-install

Answer: B

Explanation:
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.

NEW QUESTION # 27
The openstack user list command uses which OpenStack service?

A. Nova
B. Keystone
C. Cinder
D. Neutron

Answer: B

Explanation:
OpenStack provides various services to manage cloud infrastructure resources, including user management. Let's analyze each option:
A . Cinder
Incorrect: Cinder is the OpenStack block storage service that provides persistent storage volumes for virtual machines. It is unrelated to managing users.
B . Keystone
Correct: Keystone is the OpenStack identity service responsible for authentication, authorization, and user management. The openstack user list command interacts with Keystone to retrieve a list of users in the OpenStack environment.
C . Nova
Incorrect: Nova is the OpenStack compute service that manages virtual machine instances. It does not handle user management.
D . Neutron
Incorrect: Neutron is the OpenStack networking service that manages virtual networks, routers, and IP addresses. It is unrelated to user management.
Why Keystone?
Identity Management: Keystone serves as the central identity provider for OpenStack, managing users, roles, and projects.
API Integration: Commands like openstack user list rely on Keystone's APIs to query and display user information.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers OpenStack services, including Keystone, as part of its cloud infrastructure curriculum. Understanding Keystone's role in user management is essential for operating OpenStack environments.
For example, Juniper Contrail integrates with OpenStack Keystone to enforce authentication and authorization for network resources.
