Juniper Cloud, Associate (JNCIA-Cloud) Sample Questions (Q25-Q30):

NEW QUESTION # 25
Which statement about software-defined networking is true?

A. It must manage networks through the use of containers and repositories.
B. It manages networks by separating the data forwarding plane from the control plane.
C. It applies security policies individually to each separate node.
D. It manages networks by merging the data forwarding plane with the control plane.

Answer: B

Explanation:
Software-Defined Networking (SDN) is a revolutionary approach to network management that separates the control plane from the data (forwarding) plane. Let's analyze each option:
A . It must manage networks through the use of containers and repositories.
Incorrect: While containers and repositories are important in cloud-native environments, they are not a requirement for SDN. SDN focuses on programmability and centralized control, not containerization.
B . It manages networks by separating the data forwarding plane from the control plane.
Correct: SDN separates the control plane (decision-making) from the data forwarding plane (packet forwarding). This separation enables centralized control, programmability, and dynamic network management.
C . It applies security policies individually to each separate node.
Incorrect: SDN applies security policies centrally through the SDN controller, not individually to each node. Centralized policy enforcement is one of the key advantages of SDN.
D . It manages networks by merging the data forwarding plane with the control plane.
Incorrect: Merging the forwarding and control planes contradicts the fundamental principle of SDN. The separation of these planes is what enables SDN's flexibility and programmability.
Why This Answer?
Separation of Planes: By decoupling the control plane from the forwarding plane, SDN enables centralized control over network devices. This architecture simplifies network management, improves scalability, and supports automation.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers SDN as a core concept in cloud networking. Understanding the separation of the control and forwarding planes is essential for designing and managing modern cloud environments.
For example, Juniper Contrail serves as an SDN controller, centralizing control over network devices and enabling advanced features like network automation and segmentation.

NEW QUESTION # 26
You are provisioning workloads on worker nodes in a Kubernetes cluster.
Which CN2 component is responsible for generating associated routes?

A. vRouter agent microservice
B. vRouter forwarding plane
C. Configuration Resource (CR) controllers
D. Contrail kube-manager

Answer: A

Explanation:
The vRouter agent microservice is the CN2 component responsible for generating associated routes. When a pod is scheduled on a node, the vRouter agent on that node programs the necessary routes in the kernel routing table to ensure that traffic destined for that pod is properly routed.

NEW QUESTION # 27
Which SDN model provisions tunnels between the virtual endpoints within and across data centers?

A. open SDN
B. switch-based SDN
C. SDN by APIs
D. SDN overlay

Answer: D

Explanation:
The SDN overlay model provisions tunnels between the virtual endpoints within and across data centers. This model uses network overlays to support private communication between instances.

NEW QUESTION # 28
Which two Linux commands would you use to show the amount of RAM in your system? (Choose two.)

A. cat /proc/meminto
B. cat /proc/cpuinfo
C. free -h
D. df -h

Answer: A,C

Explanation:
he free -h command in Linux displays the total amount of free and used physical and swap memory in the system, as well as the buffers used by the kernel. The cat /proc/meminfo command displays real-time information about the system's memory usage as well as the buffers and shared memory used by the kernel.

NEW QUESTION # 29
Which cloud service model provides access to networking, storage, servers, and virtualization in a cloud environment?

A. Infrastructure as a Service (IaaS)
B. Software as a Service (SaaS)
C. Platform as a Service (PaaS)
D. Database as a Service (DaaS)

Answer: A

Explanation:
Cloud service models define how services are delivered and managed in a cloud environment. The three primary models are:
Infrastructure as a Service (IaaS): Provides virtualized computing resources such as servers, storage, networking, and virtualization over the internet. Customers manage their own operating systems, applications, and data, while the cloud provider manages the underlying infrastructure.
Platform as a Service (PaaS): Provides a platform for developers to build, deploy, and manage applications without worrying about the underlying infrastructure. Examples include Google App Engine and Microsoft Azure App Services.
Software as a Service (SaaS): Delivers fully functional applications over the internet, eliminating the need for users to install or maintain software locally. Examples include Salesforce CRM, Google Workspace, and Microsoft Office 365.
Database as a Service (DaaS): A specialized subset of PaaS that provides managed database services.
In this question, the focus is on access to networking, storage, servers, and virtualization , which are the core components of IaaS . IaaS allows customers to rent infrastructure on-demand and build their own environments without investing in physical hardware.
Why IaaS?
Flexibility: Customers have full control over the operating systems, applications, and configurations.
Scalability: Resources can be scaled up or down based on demand.
Cost Efficiency: Pay-as-you-go pricing eliminates upfront hardware costs.
JNCIA Cloud Reference:
The JNCIA-Cloud certification emphasizes understanding the different cloud service models and their use cases. IaaS is particularly relevant for organizations that want to leverage cloud infrastructure while maintaining control over their applications and data.
For example, Juniper Contrail integrates with IaaS platforms like OpenStack to provide advanced networking and security features for virtualized environments.
