2V0-41.24 Question 153
Select 3A network administrator is tasked with segmenting traffic between multiple departments in a data center without deploying additional physical routers. The administrator wants to maintain separate routing tables for each department to ensure traffic isolation. How does VRF Lite provide a solution to this requirement?
- A
It allows multiple virtual routing tables to coexist on a single physical router.
- B
It eliminates the need for VLANs by providing layer 3 segmentation only.
- C
It ensures traffic isolation by maintaining separate forwarding tables for each VRF instance.
- D
It requires MPLS to function, ensuring scalability in large networks.
- E
It simplifies network management by enabling logical segmentation without additional hardware.
Show answer and explanation
Correct answers: A, C, E
Explanation
VRF Lite provides the benefits of traffic isolation and routing segmentation by allowing multiple virtual routing and forwarding tables to coexist on a single physical router. It simplifies network management and is ideal for scenarios where logical segmentation is needed without additional hardware or complex MPLS configurations. By maintaining separate forwarding tables for each VRF instance, VRF Lite ensures that traffic remains isolated between departments or tenants.
- A. Correct.
Correct: VRF Lite enables multiple virtual routing tables to operate on a single physical router, which is key for traffic segmentation between departments.
- B. Incorrect.
Incorrect: VRF Lite works in conjunction with VLANs but does not replace them. VLANs are used for layer 2 segmentation, while VRF Lite handles layer 3 routing segmentation.
- C. Correct.
Correct: By maintaining separate forwarding tables for each VRF instance, VRF Lite ensures traffic isolation, which is crucial for departmental segregation.
- D. Incorrect.
Incorrect: VRF Lite does not require MPLS to function. It is a simplified approach for traffic segmentation and typically used in environments where MPLS is unnecessary.
- E. Correct.
Correct: VRF Lite allows logical segmentation of routing without requiring additional physical hardware, simplifying network management.
