Which entity is responsible for maintaining Layer 2 isolation between segments in a VXLAN environment?
The VNID (VXLAN Network Identifier) is responsible for maintaining Layer 2 isolation between segments in a VXLAN environment. The VNID is a 24-bit segment ID that is used to define broadcast domains within VXLAN. It essentially tags packets with a unique identifier, ensuring that traffic is kept isolated between different segments, much like how VLAN IDs are used in traditional Ethernet networks. With the larger bit length, VNID allows for a significantly larger number of isolated segments compared to VLAN IDs.
A: VNID - VXLAN Network IDentifier.
VXLAN (Virtual Extensible LAN) - The technology that provides the same Ethernet Layer 2 network services as VLAN does today, but with greater extensibility and flexibility. VNID (Vxlan Network Identifier) - 24 bit segment ID that defines the broadcast domain. Interchangeable with "VXLAN Segment ID". VTEP (Virtual Tunnel Endpoint) - This is the device that does the encapsulation and de-encapsulation. NVE (Network Virtual Interface) - Logical interface where the encapsulation and de-encapsulation occur.
VNID is not an entity, is a technology (see also Question #85) the entity that enforces isolation based on the VNID is the VTEP
I agree
I agree as well
A is correct : The 24-bit VNID is used to identify Layer 2 segments and to maintain Layer 2 isolation between the segments. With all 24 bits in VNID, VXLAN can support 16 million LAN segments.

Given answer is correct
A is correct The 24-bit VNID is used to identify Layer 2 segments and to maintain Layer 2 isolation between the segments. https://www.ciscopress.com/articles/article.asp?p=2999385&seqNum=3#:~:text=The%2024%2Dbit%20VNID%20is,2%20isolation%20between%20the%20segments.

The correct ans is VTEP. VNID is a unique identifier assigned to each VXLAN segment, but it is used for identification purposes rather than for enforcing isolation between segments.
VTEP maintains the isolation
Correct answer is C. VTEP
A is correct
Unlike the VLAN ID, which has only 12 bits and allows for 4000 VLANs, VXLAN has a 24-bit VXLAN network identifier (VNI), which allows for up to 16 million VXLAN segments (more commonly known as overlay networks) to coexist within the same infrastructure. The VNI is located in the VXLAN shim header that encapsulates the original inner MAC frame originated by an endpoint. The VNI is used to provide segmentation for Layer 2 and Layer 3 traffic.
