What are the advantages of multiple virtual routers on aNetScreendevice?

A.
They provide separate routing tables that can hide internal network structure

B.
They reduce packet-forwarding overhead associated with layer-3 operations

C.
They increase the number of possible routing table entries perNetScreendevice

D.
They make it possible to forward traffic between security zones without policy lookup

Explanation:

By separating routing information into two virtual routers (VRs), you can control the information in a given routing domain that is visible to other routing domains. For example, you can keep the routing information for all the security zones inside a corporate network on the default predefined VR, trust-vr, and all the routing information for all the zones outside the corporate network on the other predefined VR,untrust-vr. Because the information in the routing table of one VR is not visible to the other VR, you can keep internal network routing information separate fromuntrustedsources outside the company.
