Juniper Cloud, Associate (JNCIA-Cloud) Sample Questions (Q58-Q63):

NEW QUESTION # 58
Which two statements are true about VRF instances? (Choose two.)

  • A. VRFs share a single routing table.
  • B. VRFs enable overlapping IP addresses within the same cloud network.
  • C. VRFs do not enable overlapping IP addresses within the same cloud network.
  • D. Each VRF has its own routing table.

Answer: B,D

Explanation:
Virtual Routing and Forwarding (VRF) is a technology that allows multiple instances of a routing table to coexist within the same router at the same time. Because the routing instances are independent, overlapping IP addresses can be used without conflict. Each VRF has its own routing table.


NEW QUESTION # 59
Which cloud automation tool uses YAML playbook to install software and tools on servers?

  • A. Heat
  • B. Terraform
  • C. Ansible
  • D. Python

Answer: C

Explanation:
Cloud automation tools streamline the deployment and management of software, tools, and infrastructure in cloud environments. Let's analyze each option:
A . Python
Incorrect: Python is a general-purpose programming language, not a cloud automation tool. While Python scripts can be used for automation, it is not specifically designed for this purpose.
B . Ansible
Correct: Ansible is a popular automation tool that uses YAML-based playbooks to define and execute tasks. It automates the installation of software, configuration management, and application deployment on servers. Ansible's simplicity and agentless architecture make it widely adopted in cloud environments.
C . Terraform
Incorrect: Terraform is an infrastructure-as-code (IaC) tool used to provision and manage cloud infrastructure (e.g., virtual machines, networks, storage). It uses HashiCorp Configuration Language (HCL), not YAML, for defining configurations.
D . Heat
Incorrect: Heat is an orchestration tool in OpenStack that uses YAML templates to define and deploy cloud resources. While it supports YAML, it is specific to OpenStack and focuses on infrastructure provisioning rather than server-level software installation.
Why Ansible?
YAML Playbooks: Ansible uses YAML-based playbooks to define tasks, making it easy to read and write automation scripts.
Agentless Architecture: Ansible operates over SSH, eliminating the need for agents on target servers.
Versatility: Ansible can automate a wide range of tasks, from software installation to configuration management.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers automation tools as part of its cloud operations curriculum. Tools like Ansible are essential for automating repetitive tasks and ensuring consistency in cloud environments.
For example, Juniper Contrail integrates with Ansible to automate the deployment and configuration of network services, enabling efficient management of cloud resources.

NEW QUESTION # 60
Which feature of Linux enables kernel-level isolation of global resources?

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

Answer: A

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 # 61
Which component of a software-defined networking (SDN) controller defines where data packets are forwarded by a network device?

  • A. the operational plane
  • B. the forwarding plane
    C the management plane
  • C. the control plane

Answer: C

Explanation:
Software-Defined Networking (SDN) separates the control plane from the data (forwarding) plane, enabling centralized control and programmability of network devices. Let's analyze each option:
A . the operational plane
Incorrect: The operational plane is not a standard term in SDN architecture. It may refer to monitoring or management tasks but does not define packet forwarding behavior.
B . the forwarding plane
Incorrect: The forwarding plane (also known as the data plane) is responsible for forwarding packets based on rules provided by the control plane. It does not define where packets are forwarded; it simply executes the instructions.
C . the management plane
Incorrect: The management plane handles device configuration, monitoring, and administrative tasks. It does not determine packet forwarding paths.
D . the control plane
Correct: The control plane is responsible for making decisions about where data packets are forwarded. In SDN, the control plane is centralized in the SDN controller, which calculates forwarding paths and communicates them to network devices via protocols like OpenFlow.
Why the Control Plane?
Centralized Decision-Making: The control plane determines the optimal paths for packet forwarding and updates the forwarding plane accordingly.
Programmability: SDN controllers allow administrators to programmatically define forwarding rules, enabling dynamic and flexible network configurations.
JNCIA Cloud Reference:
The JNCIA-Cloud certification emphasizes understanding SDN architecture and its components. The separation of the control plane and forwarding plane is a foundational concept in SDN, enabling scalable and programmable networks.
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 # 62
What is the name of the Docker container runtime?

  • A. containerd
  • B. docker cl
  • C. cri-o
  • D. dockerd

Answer: A

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.
