200-155 · Question #209

Refer to the exhibit. Which two ports are VE ports in this FCoE topology? (Choose two)

The correct answer is C. C D. D. In an FCoE topology, VE ports are specialized inter-switch links that encapsulate Fibre Channel frames within Ethernet frames to extend the Fibre Channel fabric over an Ethernet network.

Why each option

In an FCoE topology, VE ports are specialized inter-switch links that encapsulate Fibre Channel frames within Ethernet frames to extend the Fibre Channel fabric over an Ethernet network.

AA

If A represented a connection from a server's Converged Network Adapter (CNA) to an FCoE switch, it would typically be an F port (Fabric port), which connects an N_Port to an F port on the switch.

BB

If B represented a connection from a server's Converged Network Adapter (CNA) to an FCoE switch, it would typically be an F port (Fabric port), which connects an N_Port to an F port on the switch.

CCCorrect

Ports C and D are designated as VE ports because they serve as inter-switch links (ISLs) within the FCoE topology, connecting FCoE-capable switches or FCoE-enabled Fibre Channel switches and encapsulating Fibre Channel frames in Ethernet for transport across the converged network.

DDCorrect

Ports C and D are designated as VE ports because they serve as inter-switch links (ISLs) within the FCoE topology, connecting FCoE-capable switches or FCoE-enabled Fibre Channel switches and encapsulating Fibre Channel frames in Ethernet for transport across the converged network.

EE

If E represented an uplink to a traditional Fibre Channel switch or another device not acting as an FCoE ISL, it might be an E-port (Expansion Port) or an NP port, not a VE port.

FF

If F represented an uplink to a traditional Fibre Channel switch or another device not acting as an FCoE ISL, it might be an E-port (Expansion Port) or an NP port, not a VE port.
