- A
Create the VRF using the 'vrf definition <vrf-name>' command and assign a route distinguisher with the 'rd' command.
This defines the VRF and its route distinguisher, which is mandatory for VRF-Lite.
- B
Assign the VRF to an interface using the 'vrf forwarding <vrf-name>' command under interface configuration.
This binds the interface to the VRF, enabling traffic separation.
- C
Configure route target import/export statements under the VRF.
Why wrong: Route targets are used in MPLS VPN environments, not required for VRF-Lite.
- D
Apply an import map and export map to control route redistribution.
Why wrong: Import/export maps are optional and not a required step for basic VRF-Lite.
- E
Enable BGP to exchange routes between VRFs.
Why wrong: BGP is not required for VRF-Lite; static or IGP routing can be used.
Quick Answer
The correct answer is that you must create the VRF with a route distinguisher and then assign it to an interface using the `vrf forwarding` command. These two steps are non-negotiable because VRF-Lite relies on maintaining separate routing tables on a single router; the `vrf definition` command with an `rd` value creates the isolated table, while `vrf forwarding` under the interface binds that interface and its connected routes to the specific VRF instance. On the Cisco CCNP ENARSI 300-410 exam, this question tests your ability to distinguish VRF-Lite from MPLS VPN—a common trap is selecting route targets or BGP, which are only needed for MPLS-based VPNs, not for simple Layer 3 segmentation. Remember that VRF-Lite is purely local to the router, so no route-target import/export is required. A quick memory tip: think “Define and Bind”—first define the VRF with an RD, then bind it to the interface with `vrf forwarding`.
300-410 VRF-Lite Practice Question
This 300-410 practice question tests your understanding of vrf-lite. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

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
Create the VRF using the 'vrf definition <vrf-name>' command and assign a route distinguisher with the 'rd' command.
The two essential steps are: creating the VRF with a route distinguisher using 'vrf definition <name>' and 'rd <value>', and assigning interfaces to the VRF with 'vrf forwarding <name>' under the interface. The other options are incorrect: 'ip vrf <name>' is legacy syntax but still works; however, 'rd' is required. Route targets are for MPLS VPN, not VRF-Lite. Import/export maps are optional. BGP is not mandatory.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
