Juniper Cloud, Associate (JNCIA-Cloud) Sample Questions (Q29-Q34):

NEW QUESTION # 29
You are asked to run a container in a Kubernetes environment.
What should you do to accomplish this task?

A. Create a JINJA2 template for the container and its resources.
B. Define a YAML manifest for the container and its resources.
C. Define an XML configuration for the container and its resources.
D. Create a WYSYG definition for the container and its resources.

Answer: B

Explanation:
Kubernetes uses declarative configuration files to define and manage resources like containers, pods, and services. Let's analyze each option:
A . Create a JINJA2 template for the container and its resources.
Incorrect: JINJA2 is a templating language often used in automation tools like Ansible. While it can generate Kubernetes manifests, Kubernetes itself does not use JINJA2 templates natively.
B . Create a WYSYG definition for the container and its resources.
Incorrect: "WYSYG" (What You See Is What You Get) is not a recognized format for Kubernetes configurations. Kubernetes relies on structured formats like YAML or JSON.
C . Define a YAML manifest for the container and its resources.
Correct: Kubernetes uses YAML (or JSON) manifests to define the desired state of resources, including containers, pods, and services. A YAML manifest specifies details like container images, resource limits, environment variables, and networking.
D . Define an XML configuration for the container and its resources.
Incorrect: Kubernetes does not use XML for defining resources. YAML is the standard format due to its readability and simplicity.
Why YAML Manifests?
Declarative Configuration: YAML manifests allow you to describe the desired state of your resources in a human-readable format.
Standard Practice: Kubernetes natively supports YAML for defining and deploying resources, making it the correct choice for this task.
JNCIA Cloud Reference:
The JNCIA-Cloud certification emphasizes Kubernetes resource management, including YAML manifests. Understanding how to define and apply manifests is essential for deploying and managing containerized applications.
For example, Juniper Contrail integrates with Kubernetes to provide advanced networking features, relying on YAML manifests to configure resources.

NEW QUESTION # 30
Which two statements about Kubernetes are correct? (Choose two.)

A. Kubernetes requires the Docker daemon to run Docker containers.
B. A Kubernetes cluster must contain at least one control plane node.
C. A container is the smallest unit of computing that you can manage with Kubernetes.
D. Kubernetes is compatible with the container open container runtime.

Answer: C,D

Explanation:
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. Let's analyze each statement:
A . Kubernetes is compatible with the container open container runtime.
Correct: Kubernetes supports the Open Container Initiative (OCI) runtime standards, which ensure compatibility with various container runtimes like containerd, cri-o, and others. This flexibility allows Kubernetes to work with different container engines beyond just Docker.
B . Kubernetes requires the Docker daemon to run Docker containers.
Incorrect: While Kubernetes historically used Docker as its default container runtime, it no longer depends on the Docker daemon. Instead, Kubernetes uses the Container Runtime Interface (CRI) to interact with container runtimes like containerd or cri-o. Docker's runtime has been replaced by containerd in most modern Kubernetes deployments.
C . A container is the smallest unit of computing that you can manage with Kubernetes.
Correct: In Kubernetes, a container represents the smallest deployable unit of computing. Containers encapsulate application code, dependencies, and configurations. Kubernetes manages containers through higher-level abstractions like Pods, which are groups of one or more containers.
D . A Kubernetes cluster must contain at least one control plane node.
Incorrect: While a Kubernetes cluster typically requires at least one control plane node to manage the cluster, this statement is incomplete. A functional Kubernetes cluster also requires at least one worker node to run application workloads. Both control plane and worker nodes are essential for a fully operational cluster.
Why These Answers?
Compatibility with OCI Runtimes: Kubernetes' support for OCI-compliant runtimes ensures flexibility and avoids vendor lock-in.
Containers as Smallest Unit: Understanding that containers are the fundamental building blocks of Kubernetes is crucial for designing and managing applications in a Kubernetes environment.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers Kubernetes as part of its container orchestration curriculum. Understanding Kubernetes architecture, compatibility, and core concepts is essential for deploying and managing containerized applications in cloud environments.
For example, Juniper Contrail integrates with Kubernetes to provide advanced networking and security features for containerized workloads. Proficiency with Kubernetes ensures seamless operation of cloud-native applications.

NEW QUESTION # 31
Click the Exhibit button.

You apply the manifest file shown in the exhibit.
Which two statements are correct in this scenario? (Choose two.)

A. Four pods are created as a result of applying this manifest.
B. This manifest is used to create a deployment.
C. The created pods are receiving traffic on port 80.
D. This manifest is used to create a

Answer: A,B

Explanation:
This manifest is used to create a deployment, which is a Kubernetes resource that manages a set of pods with the same configuration. A deployment can also provide declarative updates, scaling, and rolling back for the pods. The created pods are not receiving traffic on port 80, because the manifest does not specify a service or a selector for the deployment. A service is another Kubernetes resource that defines a logical set of pods and a policy to access them. A selector is a label query that matches the pods that belong to the service. Four pods are created as a result of applying this manifest, because the manifest specifies replicas: 4 in the spec section of the deployment.

NEW QUESTION # 32
Which two statements are correct about an overlay network? (Choose two.)

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

Answer: A,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 # 33
Which component of an SDN architecture is responsible for configuring and maintaining devices and their state?

A. the forwarding plane
B. the operational plane
C. the data plane
D. the management plane

Answer: D

Explanation:
The management plane in an SDN architecture is responsible for configuring and maintaining devices and their state. It provides the functions that manage the network, such as configuration, monitoring, and management of network devices. It is the layer of the network that carries administrative traffic, which is used for the network management.
