2V0-41.24 Question 159
Single answerA network administrator is tasked with extending a legacy VLAN-based physical network into an NSX-T environment to support a gradual migration to a fully virtualized network. Which purpose and function of bridging within NSX-T can help achieve this requirement?
- A
Bridging allows NSX-T to route traffic between different virtual networks without requiring a physical connection.
- B
Bridging enables NSX-T to extend VLAN traffic from a physical network into an overlay segment.
- C
Bridging provides the ability to encrypt traffic between physical and virtual networks for secure communication.
- D
Bridging allows NSX-T to replace legacy VLANs entirely by creating isolated overlay segments.
Show answer and explanation
Correct answer: B
Explanation
The primary purpose of bridging in NSX-T is to enable seamless integration between traditional VLAN-based networks and NSX-T overlay networks. This is useful when organizations are transitioning from physical to virtualized environments while maintaining compatibility with legacy systems. By mapping VLANs to overlay segments, bridging helps ensure that physical devices can communicate with virtualized workloads within NSX-T.
- A. Incorrect.
This is incorrect because routing between virtual networks is managed by logical routers in NSX-T, not by bridging.
- B. Correct.
This is correct as bridging in NSX-T is specifically designed to extend VLAN traffic from a physical network into an NSX-T overlay segment, enabling interoperability between physical and virtualized environments.
- C. Incorrect.
This is incorrect because bridging in NSX-T does not provide encryption capabilities. Encryption is typically managed through other mechanisms such as IPsec or TLS.
- D. Incorrect.
This is incorrect because bridging does not replace VLANs but rather integrates them with NSX-T overlay segments for a hybrid environment.
