300-320 · Question #66

Which three options are benefits of using VRFs within an enterprise network? (Choose three.)

The correct answer is B. enables partitioning of network resources C. enhances security between user groups E. allows for routing and forwarding separation. VRFs (Virtual Routing and Forwarding) benefit enterprise networks by partitioning routing tables, isolating traffic between user groups for security, and separating the routing and forwarding planes.

Why each option

VRFs (Virtual Routing and Forwarding) benefit enterprise networks by partitioning routing tables, isolating traffic between user groups for security, and separating the routing and forwarding planes.

Asimplifies configuration and troubleshooting

VRFs increase configuration and troubleshooting complexity because administrators must manage multiple routing instances and track which interfaces and routes belong to which VRF.

Benables partitioning of network resourcesCorrect

VRFs create multiple independent routing table instances on a single device, partitioning network resources so that different departments, customers, or services have their own isolated routing domains.

Cenhances security between user groupsCorrect

Because each VRF maintains a separate routing and forwarding table, traffic from one VRF cannot reach another without explicit policy (such as route leaking or a firewall), enhancing security between user groups.

Dprovides additional redundancy at Layer 3

VRFs provide logical isolation, not additional redundancy - they do not create duplicate physical or logical paths and do not improve Layer 3 fault tolerance.

Eallows for routing and forwarding separationCorrect

VRFs are the mechanism by which a router maintains separate routing and forwarding instances simultaneously, which is the core architectural benefit of VRF technology.

Fimproves routing protocol convergence

Routing protocol convergence is governed by timers, topology, and protocol design, not by whether VRFs are in use - VRFs have no direct impact on convergence speed.
