200-150 · Question #168
Refer to the exhibit. Which type of port is used to connect an edge switch in NIPV mode to the core switch?
The correct answer is C. NP. In Fibre Channel NPV (N-Port Virtualization) mode, an edge switch uses NP (N-Port Proxy) ports for its uplink connection to the core fabric switch.

Why each option
In Fibre Channel NPV (N-Port Virtualization) mode, an edge switch uses NP (N-Port Proxy) ports for its uplink connection to the core fabric switch.
E (Expansion) ports are ISL ports used to connect two fully-capable fabric switches together, not for NPV-to-core uplinks.
F (Fabric) ports accept connections from end-device host bus adapters or storage targets, not from NPV uplink connections.
An NP (N-Port Proxy) port is the designated port type on an NPV-mode edge switch for its upstream connection to the core switch. The NP port aggregates multiple host N-Port logins and proxies them to the core fabric, allowing the edge switch to operate without running full fabric services like FSPF or domain ID assignment.
TE (Trunking Expansion) ports are trunked ISL connections between core fabric switches and do not apply to NPV edge switch uplinks.
Concept tested: NPV mode NP port uplink to core switch
