NEW QUESTION # 18
Click the Exhibit button.
Referring to the exhibit, which two statements are correct? (Choose two.)
Answer: C,D
Explanation:
Based on the image description provided, the instance named 'myvSRX' appears to be using a custom flavor (not default) and is currently in an 'ACTIVE' state, which means it is running.
NEW QUESTION # 19
What are the two primary ways used to manage objects by kubectl? (Choose two.)
Answer: B,D
Explanation:
The two primary ways used to manage objects by kubectl are imperative commands and declarative object configuration. Imperative commands operate directly on live objects in a cluster. The user provides operations to the kubectl command as arguments or flags. Declarative object configuration specifies the operation (create, replace, etc.), optional flags and at least one file name. The file specified must contain a full definition of the object in YAML or JSON format.
NEW QUESTION # 20
You just uploaded a qcow2 image of a vSRX virtual machine in OpenStack.
In this scenario, which service stores the virtual machine (VM) image?
Answer: A
Explanation:
OpenStack provides various services to manage cloud infrastructure resources, including virtual machine (VM) images. Let's analyze each option:
A . Glance
Correct: Glance is the OpenStack service responsible for managing and storing VM images. It provides a repository for uploading, discovering, and retrieving images in various formats, such as qcow2, raw, or ISO.
B . Ironic
Incorrect: Ironic is the OpenStack bare-metal provisioning service. It is used to manage physical servers, not VM images.
C . Neutron
Incorrect: Neutron is the OpenStack networking service that manages virtual networks, routers, and IP addresses. It does not store VM images.
D . Nova
Incorrect: Nova is the OpenStack compute service that manages the lifecycle of virtual machines. While Nova interacts with Glance to retrieve VM images for deployment, it does not store the images itself.
Why Glance?
Image Repository: Glance acts as the central repository for VM images, enabling users to upload, share, and deploy images across the OpenStack environment.
Integration with Nova: When deploying a VM, Nova retrieves the required image from Glance to create the instance.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers OpenStack services, including Glance, as part of its cloud infrastructure curriculum. Understanding Glance's role in image management is essential for deploying and managing virtual machines in OpenStack.
For example, Juniper Contrail integrates with OpenStack Glance to provide advanced networking features for VM images stored in the repository.

NEW QUESTION # 21
What is the name of the Docker container runtime?
Answer: D
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 # 22
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?
Answer: A
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:
A . ADOT
Incorrect: The AWS Distro for OpenTelemetry (ADOT) is a tool for collecting and exporting telemetry data (metrics, logs, traces). It is unrelated to running VMs in Kubernetes.
B . Canal
Incorrect: Canal is a networking solution that combines Flannel and Calico to provide overlay networking and network policy enforcement in Kubernetes. It does not support VM workloads.
C . KubeVirt
Correct: KubeVirt is a Kubernetes add-on that enables the management of virtual machines alongside containers in a Kubernetes cluster. It allows organizations to run legacy VM workloads while leveraging Kubernetes for orchestration.
D . Romana
Incorrect: Romana is a network policy engine for Kubernetes that provides security and segmentation. It does not support VM workloads.
Why KubeVirt?
VM Support in Kubernetes: KubeVirt extends Kubernetes to manage both containers and VMs, enabling organizations to transition legacy workloads to a Kubernetes environment.
Unified Orchestration: By integrating VMs into Kubernetes, KubeVirt simplifies the management of hybrid workloads.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers Kubernetes extensions like KubeVirt as part of its curriculum on cloud-native architectures. Understanding how to integrate legacy workloads into Kubernetes is essential for modernizing IT infrastructure.
For example, Juniper Contrail integrates with Kubernetes and KubeVirt to provide networking and security for hybrid workloads.
