Juniper Cloud, Associate (JNCIA-Cloud) Sample Questions (Q10-Q15):

NEW QUESTION # 10
What are the two characteristics of the Network Functions Virtualization (NFV) framework?
(Choose two.)

  • A. It implements virtualized tunnel endpoints.
  • B. It implements virtualized network functions
  • C. It decouples the network control plane from the forwarding plane.
  • D. It decouples the network software from the hardware.

Answer: B,D

Explanation:
The two characteristics of the Network Functions Virtualization (NFV) framework are that it implements virtualized network functions (VNFs) and that it decouples the network software from the hardware. According to the NFV overview by VMware, NFV is "designed to deliver the network services needed to support an infrastructure totally independent from hardware by decoupling network functions from proprietary purpose-built hardware appliances" and that "the software that provides these network services are known as virtual network functions (VNFs) and run on generic hardware". Other characteristics that are mentioned in the question are related to Software Defined Networking (SDN), not NFV. SDN separates the network control plane from the forwarding plane and implements virtualized tunnel endpoints.


NEW QUESTION # 11
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. The created pods are receiving traffic on port 80.
  • C. This manifest is used to create a deployment.
  • D. This manifest is used to create a

Answer: A,C

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 # 12
Which Linux protection ring is the least privileged?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: B

Explanation:
In Linux systems, the concept of protection rings is used to define levels of privilege for executing processes and accessing system resources. These rings are part of the CPU's architecture and provide a mechanism for enforcing security boundaries between different parts of the operating system and user applications. There are typically four rings in the x86 architecture, numbered from 0 to 3:
Ring 0 (Most Privileged): This is the highest level of privilege, reserved for the kernel and critical system functions. The operating system kernel operates in this ring because it needs unrestricted access to hardware resources and control over the entire system.
Ring 1 and Ring 2: These intermediate rings are rarely used in modern operating systems. They can be utilized for device drivers or other specialized purposes, but most operating systems, including Linux, do not use these rings extensively.
Ring 3 (Least Privileged): This is the least privileged ring, where user-level applications run. Applications running in Ring 3 have limited access to system resources and must request services from the kernel (which runs in Ring 0) via system calls. This ensures that untrusted or malicious code cannot directly interfere with the core system operations.
Why Ring 3 is the Least Privileged:
Isolation: User applications are isolated from the core system functions to prevent accidental or intentional damage to the system.
Security: By restricting access to hardware and sensitive system resources, the risk of vulnerabilities or exploits is minimized.
Stability: Running applications in Ring 3 ensures that even if an application crashes or behaves unexpectedly, it does not destabilize the entire system.
JNCIA Cloud Reference:
The Juniper Networks Certified Associate - Cloud (JNCIA-Cloud) curriculum emphasizes understanding virtualization, cloud architectures, and the underlying technologies that support them. While the JNCIA-Cloud certification focuses more on Juniper-specific technologies like Contrail, it also covers foundational concepts such as virtualization, Linux, and cloud infrastructure.
In the context of virtualization and cloud environments, understanding the role of protection rings is important because:
Hypervisors often run in Ring 0 to manage virtual machines (VMs).
VMs themselves run in a less privileged ring (e.g., Ring 3) to ensure isolation between the guest operating systems and the host system.
For example, in a virtualized environment like Juniper Contrail, the hypervisor (e.g., KVM) manages the execution of VMs. The hypervisor operates in Ring 0, while the guest OS and applications within the VM operate in Ring 3. This separation ensures that the VMs are securely isolated from each other and from the host system.
Thus, the least privileged Linux protection ring is Ring 3 , where user applications execute with restricted access to system resources.

NEW QUESTION # 13
Which two statements are correct about Kubernetes resources? (Choose two.)

  • A. A deploymentConfig is a Kubernetes resource.
  • B. A ClusterIP type service can only be accessed within a Kubernetes cluster.
  • C. NodePort service exposes the service externally by using a cloud provider load balancer.
  • D. A daemonSet ensures that a replica of a pod is running on all nodes.

Answer: B,D

Explanation:
Incorrect:
A NodePort service exposes the service on a static port on each node in the cluster, allowing external access via the node's IP address and the assigned port. However, it does not use a cloud provider load balancer. The LoadBalancer service type is the one that leverages cloud provider load balancers for external access.
Why These Statements?
ClusterIP: Ensures internal-only communication, making it suitable for backend services that do not need external exposure.
DaemonSet: Guarantees that a specific pod runs on all nodes, ensuring consistent functionality across the cluster.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers Kubernetes resources and their functionalities, including services, DaemonSets, and Deployments. Understanding these concepts is essential for managing Kubernetes clusters effectively.
For example, Juniper Contrail integrates with Kubernetes to provide advanced networking features for services and DaemonSets, ensuring seamless operation of distributed applications.
Explanation:
Kubernetes resources are the building blocks of Kubernetes clusters, enabling the deployment and management of applications. Let's analyze each statement:
A . A ClusterIP type service can only be accessed within a Kubernetes cluster.
Correct:
A ClusterIP service is the default type of Kubernetes service. It exposes the service internally within the cluster, assigning it a virtual IP address that is accessible only to other pods or services within the same cluster. External access is not possible with this service type.
B . A daemonSet ensures that a replica of a pod is running on all nodes.
Correct:
A daemonSet ensures that a copy of a specific pod is running on every node in the cluster (or a subset of nodes if specified). This is commonly used for system-level tasks like logging agents or monitoring tools that need to run on all nodes.
C . A deploymentConfig is a Kubernetes resource.
Incorrect:
deploymentConfig is a concept specific to OpenShift, not standard Kubernetes. In Kubernetes, the equivalent resource is called a Deployment , which manages the desired state of pods and ReplicaSets.

NEW QUESTION # 14
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. Create a WYSYG definition for the container and its resources.
  • D. Define an XML configuration for the container and its resources.

Answer: B

Explanation:
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.
