The answer is that the interface fc1/1 is an NP port (proxy FW) because the FLOGI database shows multiple FCIDs—0x010000 and 0x010001—associated with the same interface. This is the key technical indicator: an NP port acts as a proxy for multiple end devices behind it, such as in a Fibre Channel NPV switch or a converged network adapter in FCoE NPV mode, allowing several FCIDs to share a single physical link. On the Cisco DCCOR / CCNP Data Center Core 350-601 exam, this concept tests your ability to identify NP port state from the FLOGI database, often appearing in exhibit-based questions where a single interface with multiple FCIDs is the trap that distinguishes NP from N or F ports. A common memory tip is “Multiple FCIDs on one link? That’s the NP port’s proxy trick.”

A
It is an F port with a hub attached.
Why wrong: F port can have multiple devices via loop? No, F port is point-to-point.
B
It is an NP port (proxy FW) because multiple FCIDs appear on the same interface.
Multiple FCIDs from different WWNs on a single interface indicate NPIV, which is typical for NPV uplink or FCoE.
C
It is a trunking E port.
Why wrong: E port would show different domain IDs; here VSAN and same domain.

Correct answer & explanation
✓
It is an NP port (proxy FW) because multiple FCIDs appear on the same interface.
The FLOGI database shows multiple FCIDs (0x010000, 0x010001) associated with the same interface fc1/1, which is characteristic of an NP port (proxy FW) in NPV mode. An NP port acts as a proxy for multiple end devices behind it, such as in a Fibre Channel NPV switch or a converged network adapter (CNA) in FCoE NPV mode, allowing multiple FCIDs to share a single physical link.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
It is a trunking E port.
Why it's wrong here
E port would show different domain IDs; here VSAN and same domain.
✗
It is a disabled port because there are two WWNs.
Why it's wrong here
Disabled port would not have entries.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume multiple FCIDs on one interface indicate a trunking E port or a misconfiguration, but in NPV mode, an NP port legitimately proxies multiple FCIDs, which is a key distinguishing feature tested in the 350-601 exam.

Detailed technical explanation
How to think about this question
In Fibre Channel NPV, an NP port (proxy FW) registers multiple FCIDs on behalf of end devices (N ports) that are behind it, using the FLOGI and FDISC processes. The FLOGI database entry for an NP port will show multiple FCIDs with the same interface but different WWNs, as each end device performs an FDISC to obtain a unique FCID. This is commonly seen in FCoE deployments where a CNA in NPV mode connects to a Fibre Channel switch, allowing multiple virtual N ports (vNICs) to share a single physical link.

Key takeaway

Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
