   A company has two VRFs: VRF-A and VRF-B. A server in VRF-A must be reachable from VRF-B, but the company wants to avoid configuring route leaking. The network team is considering using a firewall security policy to allow the traffic. What is the most accurate assessment of this approach?

   • AIt will work if the security policy is configured to allow traffic between the VRFs.
   • BIt will not work because the server's route is not present in VRF-B's routing table, so traffic cannot be forwarded.
   • CIt will work if the server's IP address is added as a static route in VRF-B.
   • DIt will work if the SD-WAN policy is configured to allow inter-VRF traffic.

   Which benefit is directly provided by implementing VRFs on a router?

   • ASimplified management by using a single routing table for all traffic
   • BIncreased physical bandwidth by aggregating multiple links
   • CIsolation of routing information between different segments or tenants
   • DAutomatic failover to a backup internet connection

   In an SD-WAN deployment, what is the role of VRF in path selection?

   • AVRF automatically selects the fastest path for all traffic
   • BVRF is used only for security, not for path selection
   • CVRF has no impact on path selection; all traffic uses the same path
   • DVRF determines which WAN links are used for traffic in that VRF

   Which mechanism is commonly used to implement route leaking between VRFs on Palo Alto Networks devices?

   • AEnabling VRF-aware NAT on the interface
   • BRedistribution of routes between VRFs using routing protocols or static routes
   • CUsing the same route table for both VRFs
   • DConfiguring a security policy that allows traffic between VRFs

   A large enterprise is planning to segment its SD-WAN into multiple VRFs to isolate different business units. The network team is concerned about the operational overhead of managing multiple routing tables and SD-WAN policies. They want to ensure that the segmentation is effective but also manageable. What should they consider?

   • ACreate a separate VRF for every application to maximize isolation.
   • BAvoid using VRFs and instead use separate physical appliances for each business unit.
   • CUse a limited number of VRFs that align with security requirements, and apply consistent SD-WAN policies per VRF.
   • DUse a single VRF and rely on firewall rules for segmentation.
