It is common in modern society that many people who are more knowledgeable and capable than others finally lost some good opportunities for development because they didn’t obtain the JN0-214 Certification. The prerequisite for obtaining the JN0-214 certification is to pass the exam, but not everyone has the ability to pass it at one time. Because of not having appropriate review methods and review materials, or not grasping the rule of the questions, so many candidates eventually failed to pass even if they have devoted much effort.

Juniper Cloud, Associate (JNCIA-Cloud) Sample Questions (Q26-Q31):

NEW QUESTION # 26
Which command should you use to obtain low-level information about Docker objects?

  • A. docker system <OBJECT_NAME>
  • B. docker inspect <OBJECT_NAME>
  • C. docker info <OBJECT_NAME>
  • D. docker container <OBJECT_NAME>

Answer: B

Explanation:
Docker provides various commands to manage and interact with Docker objects such as containers, images, networks, and volumes. To obtain low-level information about these objects, the docker inspect command is used. Let's analyze each option:
A . docker info <OBJECT_NAME>
Incorrect: The docker info command provides high-level information about the Docker daemon itself, such as the number of containers, images, and system-wide configurations. It does not provide detailed information about specific Docker objects.
B . docker inspect <OBJECT_NAME>
Correct: The docker inspect command retrieves low-level metadata and configuration details about Docker objects (e.g., containers, images, networks, volumes). This includes information such as IP addresses, mount points, environment variables, and network settings. It outputs the data in JSON format for easy parsing and analysis.
C . docker container <OBJECT_NAME>
Incorrect: The docker container command is a parent command for managing containers (e.g., docker container ls, docker container start). It does not directly provide low-level information about a specific container.
D . docker system <OBJECT_NAME>
Incorrect: The docker system command is used for system-wide operations, such as pruning unused resources (docker system prune) or viewing disk usage (docker system df). It does not provide low-level details about specific Docker objects.
Why docker inspect?
Detailed Metadata: docker inspect is specifically designed to retrieve comprehensive, low-level information about Docker objects.
Versatility: It works with multiple object types, including containers, images, networks, and volumes.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers Docker as part of its containerization curriculum. Understanding how to use Docker commands like docker inspect is essential for managing and troubleshooting containerized applications in cloud environments.
For example, Juniper Contrail integrates with container orchestration platforms like Kubernetes, which rely on Docker for container management. Proficiency with Docker commands ensures effective operation and debugging of containerized workloads.

NEW QUESTION # 27
Click the Exhibit button.

Referring to the exhibit, which statement is correct?

  • A. There are no projects.
  • B. There are no compute nodes.
  • C. There are no services.
  • D. There are no virtual machines.

Answer: D

Explanation:
There are no virtual machines. Referring to the exhibit, which shows the output of the openstack server list command, we can see that there are no rows in the table, which means that there are no servers (or virtual machines) in the OpenStack environment. The command openstack server list is used to list servers that you can access. The other statements are incorrect, because the exhibit does not show any information about projects, services, or compute nodes. To list projects, you would use the command openstack project list. To list services, you would use the command openstack service list. To list compute nodes, you would use the command openstack compute service list.


NEW QUESTION # 28
Which two statements are correct about an overlay network? (Choose two.)

  • A. The overlay network can only be built using a Layer 3 underlay network.
  • B. The overlay network is the virtual network used to connect multiple virtual machines (VMs).
  • C. The overlay network provides physical connectivity between devices.
  • D. The overlay network is built using encapsulation tunnels.

Answer: B,D

Explanation:
An overlay network is a virtual network that is built on top of another network. Nodes in the overlay network are connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network. For example, distributed systems such as peer-to-peer networks and client-server applications often overlay their own network connections over the physical network connections provided by the Internet.


NEW QUESTION # 29
Which two statements are correct about OpenStack networks? (Choose two.)

  • A. It is not possible to specify a subnet address in an OpenStack network.
  • B. It is not possible to add host routes in the DHCP settings in an OpenStack network.
  • C. It is possible to enable DHCP for a subnet in an OpenStack network.
  • D. It is possible to share networks with other projects in an OpenStack network.

Answer: C,D

Explanation:
In OpenStack networks, it is possible to share networks with other projects. Also, it is possible to enable DHCP for a subnet in an OpenStack network.


NEW QUESTION # 30
The Kubernetes object definition file is in which format?

  • A. YAML
  • B. IXML
  • C. TXT
  • D. HTML

Answer: A

Explanation:
The Kubernetes object definition file is in YAML format. Kubernetes objects are represented in the Kubernetes API, and you can express them in .yaml format. You can execute kubectl get deployment <deployment-name> -o yaml to get the deployment definition in a yaml format.
