Why each option
During the Cisco ACI fabric discovery process, VLAN 3600 is automatically configured and is known as the Infrastructure VLAN.
Transit VLAN is a general networking term and not the specific ACI designation for VLAN 3600.
VLAN 3600 is reserved by Cisco ACI as the Infrastructure VLAN, which is essential for internal communication within the fabric. This VLAN facilitates communication between APIC controllers and fabric switches, enabling various infrastructure services and control plane functions.
Loopback VLAN is not a standard ACI term for VLAN 3600; loopbacks refer to logical interfaces, not a fabric-wide control plane VLAN.
Fabric VLAN is a generic term that does not specifically refer to VLAN 3600 and its distinct infrastructure role in ACI.
