2V0-41.24 Question 53
Select 3An organization has deployed VMware NSX-T Data Center in their environment. They have multiple VLANs in their legacy infrastructure and want to integrate these VLANs with their NSX-T logical switches for seamless communication. As a network administrator, you need to decide which type of logical switch and configuration is required to enable this integration. Which of the following configuration steps would be necessary to achieve this?
- A
Create a VLAN-backed logical switch and map it to the appropriate VLAN ID.
- B
Create an overlay-backed logical switch and connect it to the physical VLAN through a Tier-1 gateway.
- C
Ensure the physical network supports the VLAN IDs used by the VLAN-backed logical switch.
- D
Configure a Transport Zone that supports VLAN-backed logical switches and assign it to the logical switch.
- E
Enable multicast replication mode for the overlay logical switch to support VLAN integration.
Show answer and explanation
Correct answers: A, C, D
Explanation
To integrate physical VLANs with NSX-T logical switches, you must use a VLAN-backed logical switch. This requires creating the logical switch, mapping it to the corresponding VLAN ID, and ensuring the physical network supports these VLAN IDs. Additionally, a Transport Zone that supports VLAN-backed logical switches must be configured and assigned. Overlay-backed switches and multicast replication modes are unrelated to VLAN integration.
- A. Correct.
Correct. A VLAN-backed logical switch is necessary to map NSX-T logical switching to physical VLANs for communication between the virtual and physical network.
- B. Incorrect.
Incorrect. An overlay-backed logical switch is used for NSX overlay networks and does not natively integrate with physical VLANs.
- C. Correct.
Correct. The physical network must support the VLAN IDs being used by the VLAN-backed logical switch; otherwise, communication would fail.
- D. Correct.
Correct. A Transport Zone that supports VLAN-backed logical switches is mandatory to enable VLAN integration in NSX-T.
- E. Incorrect.
Incorrect. Multicast replication is used for overlay logical switches in very specific scenarios and is unrelated to VLAN integration.
