2V0-41.24 Question 157
Select 4An organization is deploying NSX-T Data Center in their environment and needs to extend a VLAN from their physical network into the overlay network. They decide to use a Layer 2 Bridge to achieve this. Which of the following is required for the Layer 2 Bridge configuration to function correctly?
- A
The VLAN to be bridged must be trunked to the Transport Node hosting the bridge.
- B
The Layer 2 Bridge must be configured on an Edge Transport Node.
- C
The VLAN to be bridged must be mapped to a Segment in the NSX-T overlay.
- D
A Tier-0 Gateway must be configured to enable bridging functionality.
- E
The Layer 2 Bridge must be associated with a specific Transport Zone.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
In NSX-T, Layer 2 Bridging enables communication between a VLAN in the physical network and a Segment in the overlay network. To configure a Layer 2 Bridge, the VLAN must be trunked to the Edge Transport Node hosting the bridge, and the VLAN must be mapped to a Segment in the overlay. Additionally, the Layer 2 Bridge must be associated with the appropriate Transport Zone to define its scope. A Tier-0 Gateway is not required for bridging, as its purpose is separate from Layer 2 Bridging functionality.
- A. Correct.
Correct: The VLAN must be trunked to the Transport Node that will host the Layer 2 Bridge to ensure traffic can flow between the physical and virtual networks.
- B. Correct.
Correct: Layer 2 Bridging in NSX-T must be configured on an Edge Transport Node, as this is the component capable of bridging traffic between the physical and overlay networks.
- C. Correct.
Correct: The VLAN being bridged must be mapped to a Segment in the NSX-T overlay to ensure traffic is properly translated between the two environments.
- D. Incorrect.
Incorrect: A Tier-0 Gateway is not required for Layer 2 Bridging. It is used for routing traffic between external networks and the NSX-T environment but does not influence bridging functionality.
- E. Correct.
Correct: The Layer 2 Bridge must be associated with a specific Transport Zone to identify the scope of the bridging operation and ensure proper communication between physical and overlay networks.
