Which of the following FCoE switch port types might require you to consider an STP configuration? a VF port a SPAN port a VE port a VN port Explanation: A Fibre Channel over Ethernet (FCoE) virtual fabric (VF) interface port type might require you to consider a Spanning Tree Protocol (STP) configuration. FCoE is used in data centers to encapsulate Fibre Channel (FC) over an Ethernet network. This encapsulation enables the FC protocol to communicate over 10 gigabit-per-second (Gbps) Ethernet. There are two types of FCoE switch ports: a VF port and a virtual edge (VE) port. An FCoE VE port typically connects to an end host. If the end host is connected to an Ethernet network that is configured with virtual local area networks (VLANs), the STP configuration might require extra attention, especially if the Ethernet fabric is not using Per-VLAN Spanning Tree Plus (PVST+). A proper STP configuration on the Ethernet fabric prevents the Ethernet topology from affecting storage area network (SAN) traffic. An FCoE VE port typically connects to a port on another FC forwarder (FCF). STP does not operate on VE ports, because these ports typically connect two FCFs. FC does not require switching loop prevention, because FCFs have no concept of switching loops. VE ports typically default to trunk mode. A virtual node (VN) port is a port on an end host, such as a host bus adapter (HBA) port, not a port on an FC switch. It is this type of port to which VF ports are typically connected. Although a VN port might participate in an Ethernet VLAN that is using STP, in this scenario you have been asked to identify a switch port type for which an STP configuration might be a consideration. A switched port analyzer (SPAN) port, which is also known as a mirroring port, is a type of port that is used to collect copies of packets transmitted over another port, over a given device, or over a network. In an FCoE configuration, a SPAN destination port can be either an FC interface or an Ethernet interface. SPAN source ports, on the other hand, can be FC interfaces, virtual FC (vFC) interfaces, a virtual SAN (vSAN), a VLAN, an Ethernet interface, a port channel interface, or a SAN port channel interface.

Explanation:

A Fibre Channel over Ethernet (FCoE) virtual fabric (VF) interface port type might require you to consider a Spanning Tree Protocol (STP) configuration. FCoE is used in data centers to encapsulate Fibre Channel (FC) over an Ethernet network. This encapsulation enables the FC protocol to communicate over 10 gigabit-per-second (Gbps) Ethernet. There are two types of FCoE switch ports: a VF port and a virtual edge (VE) port.
An FCoE VE port typically connects to an end host. If the end host is connected to an Ethernet network that is configured with virtual local area networks (VLANs), the STP configuration might require extra attention, especially if the Ethernet fabric is not using Per-VLAN Spanning Tree Plus (PVST+).
