- A
The VRF will not function because route-targets are mandatory for VRF-Lite.
Why wrong: Incorrect. Route-targets are optional in VRF-Lite; they are used for route leaking but not required for basic operation.
- B
The VRF is correctly configured for VRF-Lite with a unique RD and optional route-targets.
This is correct. The RD is required, and route-targets are optional but often configured for consistency.
- C
The RD must match the route-target value exactly.
Why wrong: Incorrect. There is no requirement for the RD to match the route-target; they are independent.
- D
The VRF will only work if 'vrf forwarding' is applied to an interface.
Why wrong: Incorrect. While the VRF is defined, it becomes active only when applied to an interface, but the configuration itself is valid.
Quick Answer
The answer is that the VRF is correctly configured for VRF-Lite with a unique RD and optional route-targets. This is correct because in VRF-Lite, the route distinguisher (RD) is mandatory to create the VRF and ensure uniqueness in the routing table, while route-targets are not strictly required since there is no MP-BGP exchange between devices to propagate VPN routes. However, route-targets are still configured for interoperability and to define import/export policies if the VRF later interacts with MPLS or other protocols. On the Cisco CCNP ENARSI 300-410 exam, this tests your understanding of VRF-Lite configuration requirements and isolation—specifically that the RD alone provides layer 3 separation, while route-targets are optional in a pure VRF-Lite scenario. A common trap is assuming route-targets are mandatory for VRF-Lite, but they only become essential when MP-BGP is introduced. Memory tip: “RD for separation, RT for propagation—VRF-Lite only needs the RD.”
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.
Consider this partial configuration: ```
ip vrf CUSTOMER_B
rd 65000:1 route-target export 65000:1 route-target import 65000:1 ``` What statement is true about this VRF configuration?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The VRF is correctly configured for VRF-Lite with a unique RD and optional route-targets.
In VRF-Lite, route-targets are not strictly required because there is no MP-BGP exchange. However, they are used for interoperability and to define import/export policies if needed. The RD is mandatory to create the VRF.
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.

Same concept, more angles
1 more ways this is tested on 300-410
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Examine the following configuration: ``` interface GigabitEthernet0/1 ip vrf forwarding CUSTOMER_C ip address 10.1.1.1 255.255.255.0 no shutdown ``` What is missing from this configuration to ensure that routes from VRF CUSTOMER_C are properly isolated?
medium- A.A route-target import/export statement under the VRF definition.
- B.The command 'ip vrf forwarding CUSTOMER_C' must be preceded by 'no ip address' to avoid IP address removal.
- ✓ C.Nothing is missing; this configuration provides proper VRF isolation.
- D.A 'vrf definition CUSTOMER_C' must be used instead of 'ip vrf' on newer IOS versions.
Why C: The configuration is complete for basic VRF-Lite. VRF isolation is achieved by associating the interface with a VRF, which creates a separate routing table. No additional commands are required for isolation.
