Exam 300-410 topic 1 question 489 discussion

A. no, one VRF per site should suffice B. this is kind of the point of VRFs. true C. no, customer sites are not directly connected to P devices, so i don't consider this true D. no, this is what we avoid by using vrfs E. yes, you cannot associate multiple VRFs to one interface.

B & E are correct

Show run: vrf definition doop ! vrf definition goop ! IOU1(config-vrf)#int e0/0 IOU1(config-if)#vrf for IOU1(config-if)#vrf forwarding IOU1(config-if)#vrf forwarding doop IOU1(config-if)#int e0/0 IOU1(config-if)#vrf forwarding goop IOU1(config-if)# show run: interface Ethernet0/0 vrf forwarding goop no ip address shutdown answer = E. And B is obvious.

for me is AB, E is not mandatory to configure a vrf on a interface

Two characteristics of a VRF (Virtual Routing and Forwarding) instance are: B. Each VRF has a different set of routing and CEF tables: VRFs maintain separate routing and CEF (Cisco Express Forwarding) tables, allowing different VRFs to have isolated routing information and forwarding decisions. E. An interface must be associated with one VRF: Interfaces on a router or switch are typically associated with a specific VRF. This association ensures that traffic on that interface is segregated and follows the routing information within the designated VRF. So, the correct options are B and E.
