Exam JN0-362 topic 1 question 62 discussion

I think D is correct

Correct answer is D. Answer A would be incorrect since, considering you already have a large netowork, by simply configuring a 'virtual-router 'routing-instance', it will not separate the the large network into smaller administrative entities. In fact it would make everything more complex. This simply would not be the main task of a 'virtual-router 'routing-instance'. Answer B is incorrect since several 'routing-instance' types exist like: evpn, l2vpn, mpls-forwarding, virtual-switch, vpls, others... Answer C is incorrect since, there exist different main mechanisms to deal with L3 VPN implementations.

Correct answer is D. When a 'routing-instance' - 'instance-type' - 'virtual-router' is created a new routing table, thus forwarding table is logically created. Evidence: admin@Juniper-1# set routing-instances TEST instance-type virtual-router admin@Juniper-1# run show route | match TEST TEST.inet6.0: 1 destinations, 1 routes (1 active, 0 holddown, 0 hidden)←←← admin@Juniper-1# run show route forwarding-table | match TEST Routing table: TEST.inet←←← Routing table: TEST.iso←←← Routing table: TEST.inet6←←←

B. is correct only logical-system is used to separate large networks into smaller administrative entities
