Juniper Cloud, Associate (JNCIA-Cloud) Sample Questions (Q62-Q67):

NEW QUESTION # 62
What are the two characteristics of the Network Functions Virtualization (NFV) framework? (Choose two.)

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

Answer: B,C

Explanation:
Network Functions Virtualization (NFV) is a framework designed to virtualize network services traditionally run on proprietary hardware. NFV aims to reduce costs, improve scalability, and increase flexibility by decoupling network functions from dedicated hardware appliances. Let's analyze each statement:
A . It implements virtualized tunnel endpoints.
Incorrect: While NFV can support virtualized tunnel endpoints (e.g., VXLAN gateways), this is not a defining characteristic of the NFV framework. Tunneling protocols are typically associated with SDN or overlay networks rather than NFV itself.
B . It decouples the network software from the hardware.
Correct: One of the primary goals of NFV is to separate network functions (e.g., firewalls, load balancers, routers) from proprietary hardware. Instead, these functions are implemented as software running on standard servers or virtual machines.
C . It implements virtualized network functions.
Correct: NFV replaces traditional hardware-based network appliances with virtualized network functions (VNFs). Examples include virtual firewalls, virtual routers, and virtual load balancers. These VNFs run on commodity hardware and are managed through orchestration platforms.
D . It decouples the network control plane from the forwarding plane.
Incorrect: Decoupling the control plane from the forwarding plane is a characteristic of Software-Defined Networking (SDN), not NFV. While NFV and SDN are complementary technologies, they serve different purposes. NFV focuses on virtualizing network functions, while SDN focuses on programmable network control.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers NFV as part of its discussion on cloud architectures and virtualization. NFV is particularly relevant in modern cloud environments because it enables flexible and scalable deployment of network services without reliance on specialized hardware.
For example, Juniper Contrail integrates with NFV frameworks to deploy and manage VNFs, enabling service providers to deliver network services efficiently and cost-effectively.

NEW QUESTION # 63
Which two statements are correct about Network Functions Virtualization (NFV)? (Choose two.)

  • A. the NFV framework explains how VNFs fits into the whole solution.
  • B. The NFV Infrastructure (NFVI) is a component of NFV.
  • C. The NFV framework is defined by the W3C.
  • D. The NFV Infrastructure (NFVI) is not a component of NFV.

Answer: A,B

Explanation:
Network Functions Virtualization (NFV) is a framework designed to virtualize network services traditionally run on proprietary hardware. It decouples network functions from dedicated hardware appliances and implements them as software running on standard servers or virtual machines. Let's analyze each statement:
A . The NFV framework explains how VNFs fit into the whole solution.
Correct: The NFV framework provides a structured approach to deploying and managing Virtualized Network Functions (VNFs). It defines how VNFs interact with other components, such as the NFV Infrastructure (NFVI), Management and Orchestration (MANO), and the underlying hardware.
B . The NFV Infrastructure (NFVI) is a component of NFV.
Correct: The NFV Infrastructure (NFVI) is a critical part of the NFV architecture. It includes the physical and virtual resources (e.g., compute, storage, networking) that host and support VNFs. NFVI acts as the foundation for deploying and running virtualized network functions.
C . The NFV Infrastructure (NFVI) is not a component of NFV.
Incorrect: This statement contradicts the NFV architecture. NFVI is indeed a core component of NFV, providing the necessary infrastructure for VNFs.
D . The NFV framework is defined by the W3C.
Incorrect: The NFV framework is defined by the European Telecommunications Standards Institute (ETSI), not the W3C. ETSI's NFV Industry Specification Group (ISG) established the standards and architecture for NFV.
Why These Answers?
Framework The NFV framework provides a comprehensive view of how VNFs integrate into the overall solution, ensuring scalability and flexibility.
NFVI Role: NFVI is essential for hosting and supporting VNFs, making it a fundamental part of the NFV architecture.
JNCIA Cloud Reference:

NEW QUESTION # 64
Which feature of Linux enables kernel-level isolation of global resources?

  • A. ring protection
  • B. shared libraries
  • C. namespaces
  • D. stack protector

Answer: C

Explanation:
Linux provides several mechanisms for isolating resources and ensuring security. Let's analyze each option:
A . ring protection
Incorrect: Ring protection refers to CPU privilege levels (e.g., Rings 0-3) that control access to system resources. While important for security, it does not provide kernel-level isolation of global resources.
B . stack protector
Incorrect: Stack protector is a compiler feature that helps prevent buffer overflow attacks by adding guard variables to function stacks. It is unrelated to resource isolation.
C . namespaces
Correct: Namespaces are a Linux kernel feature that provides kernel-level isolation of global resources such as process IDs, network interfaces, mount points, and user IDs. Each namespace has its own isolated view of these resources, enabling features like containerization.
D . shared libraries
Incorrect: Shared libraries allow multiple processes to use the same code, reducing memory usage. They do not provide isolation or security.
Why Namespaces?
Resource Isolation: Namespaces isolate processes, networks, and other resources, ensuring that changes in one namespace do not affect others.
Containerization Foundation: Namespaces are a core technology behind containerization platforms like Docker and Kubernetes, enabling lightweight and secure environments.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers Linux fundamentals, including namespaces, as part of its containerization curriculum. Understanding namespaces is essential for managing containerized workloads in cloud environments.
For example, Juniper Contrail leverages namespaces to isolate network resources in containerized environments, ensuring secure and efficient operation.

NEW QUESTION # 65
When considering OpenShift and Kubernetes, what are two unique resources of OpenShift? (Choose two.)

  • A. routes
  • B. ingress
  • C. build
  • D. services

Answer: A,C

Explanation:
OpenShift extends Kubernetes by introducing additional resources and abstractions to simplify application development and deployment. Let's analyze each option:
A . routes
Correct:
Routes are unique to OpenShift and provide a way to expose services externally by mapping a hostname to a service. They are built on top of Kubernetes Ingress but offer additional features like TLS termination and wildcard support.
B . build
Correct:
Builds are unique to OpenShift and represent the process of transforming source code into container images. OpenShift provides build configurations and strategies (e.g., Docker, S2I) to automate this process, which is not natively available in Kubernetes.
C . ingress
Incorrect:
Ingress is a standard Kubernetes resource used to manage external access to services. While OpenShift uses Ingress as the foundation for its Routes, Ingress itself is not unique to OpenShift.
D . services
Incorrect:
Services are a core Kubernetes resource used to expose applications internally within the cluster. They are not unique to OpenShift.
Why These Resources?
Routes: Extend Kubernetes Ingress to provide advanced external access capabilities, such as custom domain mappings and TLS termination.
Builds: Simplify the process of building container images directly within the OpenShift platform, enabling streamlined CI/CD workflows.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers OpenShift's unique resources as part of its curriculum on container orchestration platforms. Understanding the differences between OpenShift and Kubernetes resources is essential for leveraging OpenShift's full capabilities.
