Which of the following best describes a port that operates as part of a FabricPath network?
- a trunk port
- an edge port
- an access port
- a core port
Of the available choices, a core port is a port that operates as part of a FabricPath network. Cisco FabricPath uses Open Systems Interconnection (OSI) networking model Layer 3 routing combined with Layer 2 switching to construct a unified and scalable Layer 2 fabric. Although Cisco FabricPath defines two types of ports, only core ports are considered to be part of the FabricPath network. Core ports forward Ethernet frames encapsulated within a FabricPath header. In addition, core ports are always trunk ports that include an Institute of Electrical and Electronics Engineers (IEEE) 802.1Q virtual local area network (VLAN) tag. Only FabricPath VLANs are allowed on core ports.
An edge port is a Cisco FabricPath component port that does not operate as part of the FabricPath network. Instead, edge ports send only normal Ethernet frames as part of a classic Layer 2 switched network. An edge port can be configured as either an access port or an IEEE 802.1Q trunk port.
Although all core ports are trunk ports, not all trunk ports are core ports. Therefore, of the available choices, the term trunk port does not best describe a port that operates as part of a FabricPath network. Trunk ports enable switches to transmit and receive data on multiple VLANs over the same link.
An access port does not best describe a port that operates as part of a FabricPath network. Core ports cannot be access ports. An access port is a switch port that typically connects to an end device, such as a server or workstation. Access ports transmit and receive data on a single VLAN.
