What can the administrator use to identify overlay segments in an NSX environment if troubleshooting is required?
In an NSX environment, overlay segments are identified by a Virtual Network Identifier (VNI). The VNI is used as an overlay network identifier for logical switches within the NSX architecture. This identifier is crucial when troubleshooting overlay networks to distinguish between different segments.
Because it says Overlay segments, it's A VNI. Otherwise it could be B. VLAN ID.
According to the VMware NSX Documentation, a segment is mapped to a unique Geneve segment that is distributed across the ESXi hosts in a transport zone. The Geneve segment uses a virtual network identifier (VNI) as an overlay network identifier. The VNI ID can be used to identify overlay segments in an NSX environment if troubleshooting is required.
