350-401 Practice Question: Which two statements about VRF configuration in…
Which two statements about VRF configuration in Cisco IOS-XE are true? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A VRF instance maintains its own routing table, CEF table, and forwarding table.
Correct: VRF instances use separate routing tables and can be used with OSPF. Incorrect: VRFs do not require MPLS; VLANs are not automatically associated; VRF-lite does not support MPLS; VRF is not a Layer 2 concept.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A VRF instance maintains its own routing table, CEF table, and forwarding table.
Why this is correct
Correct because each VRF has independent forwarding and routing tables.
- ✓
VRF can be used with OSPF by configuring the OSPF process under the VRF context.
Why this is correct
Correct because OSPF supports VRF-aware routing via 'router ospf [pid] vrf [name]'.
- ✗
VRF requires MPLS to be enabled on the router.
Why it's wrong here
Incorrect because VRF-lite operates without MPLS.
- ✗
A VRF is automatically associated with all VLANs on a switch.
Why it's wrong here
Incorrect because VRF-to-interface mapping is manual.
- ✗
VRF is a Layer 2 isolation mechanism.
Why it's wrong here
Incorrect because VRF operates at Layer 3.

Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.

Key term
Virtual Routing and Forwarding
Virtual Routing and Forwarding (VRF) is a technology that allows a single physical router to operate like multiple independent routers by keeping separate routing tables and forwarding decisions for each instance.
