How to Prepare for Juniper JN0-648: Enterprise Routing and Switching, Professional (JNCIP-ENT) Exam

Preparation Guide for Juniper JN0-648: Enterprise Routing and Switching, Professional (JNCIP-ENT) Exam

Introduction

Juniper Networks, Inc. is an American multinational company based in Sunnyvale, California. The business designs and markets networking products, including routers, switches, network management tools, network security products, and software-defined networking technologies.

Juniper Networks initially concentrated on core routers used by Internet Service Providers (IENTs) to conduct IP address searches and guide internet traffic. By purchasing Unisphere, the firm joined the market in 2002 for edge routers used by IENTs to redirect Internet traffic to individual users. In 2003, Juniper joined the IT defense business with its JProtect security toolkit before purchasing NetScreen Technologies security company the following year. Juniper joined the enterprise market in the early 2000s, accounting for one-third of its sales by 2005. As of 2014, Juniper concentrated on designing innovative software-defined networking devices.

Many applicants involved in Service Provider Routing and Switching, Technical (JNCIP-ENT) qualification may be familiar with the JN0-662 test. However, the JN0-662 Lifetime Exam (EOL) concluded on June 21, 2020. You need to take the JN0-648 Juniper certification exam now to complete the Service Provider Routing and Switching, Technical (JNCIP-ENT) certification exam. Juniper JNCIP – ENT Certification is the technical standard of Juniper Service Provider Routing and Switching Certification Track. The Juniper Networks Certification Program (JNCP) Service Provider Routing and Switching Track help members to show competence in Juniper Networks technologies. Successful candidates show comprehensive knowledge of networking technologies in general and the Juniper Networks service provider routing and switching platforms. This credential protocol allows applicants to pass four tests, including the Associate Exam (JN0-103), the Expert Exam (JN0-362), and the Technical Exam (JN0-648).

In this guide, we will cover the Juniper JN0-648 practice exams, certified professionals salary, and all aspects of the Juniper JN0-648 exam dumps.

NO.41 Click the Exhibit button.

Referring to the exhibit, you must advertise the 100.0.0.0/16 routes from AS1 to AS2, but R2 is not advertising any BGP routes to R5.
Why is this happening in this scenario?

 The IBGP routes will not be advertised because you must use a policy to advertise IBGP routes.

 The IBGP routes are not active and EBGP will advertise only active routes.

 The IBGP routes will not be advertised because the AS path shows as incomplete.

 The IBGP routes are not active because the next hop is not reachable.

https://www.juniper.net/documentation/en_US/junos/topics/concept/policy-routing-policies-actions-defaults.html Default BGP Export Policy:
Readvertise all active BGP routes to all BGP speakers, while following protocol-specific rules that prohibit one IBGP speaker from readvertising routes learned from another IBGP speaker, unless it is functioning as a route reflector.
