2V0-41.24 Question 151
Select 3A network administrator is configuring network segmentation for a multi-tenant environment using VMware NSX. The goal is to enable logical separation of routing tables without the use of additional physical routers. The administrator decides to implement VRF Lite. Which of the following is a key characteristic or requirement of VRF Lite in this scenario?
- A
Each VRF instance requires a separate routing table.
- B
VRF Lite requires a physical network device to function.
- C
VRF Lite supports overlapping IP address spaces between tenants.
- D
VRF Lite can be implemented without BGP or other routing protocols.
- E
VRF Lite is limited to environments that use MPLS.
Show answer and explanation
Correct answers: A, C, D
Explanation
VRF Lite is a simplified implementation of Virtual Routing and Forwarding (VRF) that allows for logical separation of routing tables within a network. It is particularly useful in multi-tenant environments where overlapping IP address spaces are required. Unlike traditional VRF, VRF Lite does not require MPLS or complex routing protocols, making it ideal for virtualized environments like VMware NSX. This enables network administrators to create isolated routing domains using separate routing tables without relying on physical network devices.
- A. Correct.
Correct: VRF Lite creates separate routing tables for each VRF instance, enabling logical network segmentation.
- B. Incorrect.
Incorrect: VRF Lite does not require physical network devices; it can be implemented virtually in NSX environments.
- C. Correct.
Correct: One of the key benefits of VRF Lite is the ability to enable overlapping IP address spaces for different VRF instances, which is particularly useful in multi-tenant environments.
- D. Correct.
Correct: Unlike traditional VRF implementations, VRF Lite can operate without requiring BGP or other routing protocols, as it is designed for simpler deployments.
- E. Incorrect.
Incorrect: VRF Lite is not limited to MPLS environments. It can be implemented in non-MPLS deployments, such as those using VMware NSX.
