Here you have the best Juniper JN0-211 practice exam questions
You are responsible for optimizing a global MPLS WAN. You must determine the optimal MPLS forwarding paths and automate the provisioning of the forwarding paths into the network.
Which Juniper Networks SDN solution will satisfy the requirements?
The Juniper Networks SDN solution that satisfies the requirements of optimizing a global MPLS WAN, determining optimal MPLS forwarding paths, and automating the provisioning of these paths is NorthStar Controller. The NorthStar Controller is specifically designed for traffic engineering and optimization in large-scale networks, making it well-suited for this task.
Which two protocols provide loop prevention in an underlay network? (Choose two.)
OSPF and MSTP are both protocols that provide loop prevention in an underlay network. OSPF (Open Shortest Path First) uses a link-state routing algorithm that ensures loop-free paths in an IP network by constructing a logical topology. MSTP (Multiple Spanning Tree Protocol) prevents loops at the data link layer (Layer 2) by blocking some paths and allowing a single active path between any two network devices.
You are the administrator of an MPLS WAN. Intermittent WAN hardware failures are causing customer traffic to route over newly computed forwarding paths that do not satisfy service level agreements.
Which Juniper Networks solution would be used to analyze this problem?
NorthStar Planner is the correct solution because it is designed to optimize and troubleshoot MPLS networks. It helps network administrators plan, visualize, and optimize their networks to ensure that traffic is routed efficiently and according to service level agreements (SLAs). This tool allows for the analysis of forwarding paths and provides the necessary insights to address routing issues caused by hardware failures.
Which two capabilities are supported with the cSRX firewall? (Choose two.)
The cSRX firewall supports IPS (Intrusion Prevention System) for network security purposes, as it is designed to detect and prevent threats. Additionally, it supports routing instances, which allows for the segmentation of networks and the creation of virtual routers within a single physical device. Layer 2 deployment and chassis clustering are not capabilities supported by the cSRX firewall.
Which mechanism allows tenants to interconnect across an overlay network?
Tunnels are mechanisms that allow tenants to interconnect across an overlay network. They encapsulate the tenant's traffic, enabling it to travel across the underlying physical network while remaining isolated and secure. Subnets, EBGP connections, and P2P OSPF adjacencies do not specifically address the requirement of interconnecting tenants in the context of an overlay network.
