Juniper JN0-213 Cloud Associate Exam Practice Test

Answer : C

In computer science, hierarchical protection domains, often called protection rings, are mechanisms to protect data and functionality from faults and malicious behavior. Rings are arranged in a hierarchy from most privileged (most trusted, usually numbered zero) to least privileged (least trusted, usually with the highest ring number).On most operating systems, Ring 0 is the level with the most privileges and interacts most directly with the physical hardware12.

Answer : D

The term that identifies to which network a virtual machine interface is connected is the virtual network ID (VNID). The VNID is a unique identifier assigned to each virtual network. It is used to differentiate between different virtual networks and to ensure that each virtual machine interface is connected to the correct network.

Answer : C, D

In Kubernetes, a Pod is the smallest and simplest unit in the Kubernetes object model that you create or deploy23.A Pod represents processes running on your cluster23.A Service in Kubernetes is an abstraction which defines a logical set of Pods and a policy by which to access them23.

Answer : C, D

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 conflict45.Each VRF has its own routing table4.

Answer : C, D

Containers are lightweight because they don't need the extra load of a hypervisor, but run directly within the host machine's kernel1. This means they start up almost instantly and use less RAM.Images are constructed from layered filesystems and share common files, making disk usage and image downloads much more efficient1. Containers are isolated from each other and the host system.They have their own filesystem and networking, and can be constrained to not allow root access outside the container1.They run on top of a host operating system1.

Answer : C, D

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 network45.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

Answer : A, C

The OpenShift Assisted Installer uses one of the control plane nodes as a bootstrap node12.It also offers REST APIs for the configuration and installation12.
