Juniper JN0-213 Practice Test - Questions Answers

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.

The network control plane in CN2 represents CN2's full-featured SDN capability.It communicates with other controllers and uses XMPP to communicate with the distributed data plane components on the worker nodes6. Reference from Juniper site:Juniper Networks

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.

Minikube and kind are two tools that are commonly used to deploy a Kubernetes environment for testing and development purposes3

Virtual networks are logical networks that are decoupled from the underlying network hardware. This decoupling allows network administrators to manage their networks independently of the physical network topology. As such, virtual networks can span multiple devices, allowing for a high degree of flexibility and scalability. Furthermore, virtual networks are available on common Linux distributions, allowing for easy deployment and management.

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.

This technique allows multiple isolated user-space instances to be created by the host operating system.Unlike full virtualization, where the entire system's hardware is emulated, OS-level virtualization shares the host's operating system kernel but isolates the application processes12.

In Juniper Cloud-Native Contrail Networking (CN2), isolated namespaces are used to isolate a pod from other pods without explicitly configuring a network policy3.Pods in an isolated namespace can only communicate with pods in the same namespace3.They cannot reach pods or services in other isolated or non-isolated namespaces3.

MPLSoUDP (Multiprotocol Label Switching over User Datagram Protocol) and VXLAN (Virtual Extensible LAN) are two protocols that provide tunneling in the overlay and support multipath capabilities45. MPLSoUDP is an encapsulation protocol that allows MPLS packets to be encapsulated in UDP packets.VXLAN is a network virtualization technology that attempts to address the scalability problems associated with large cloud computing deployments
