350-601 NPV mode Practice Question
Exhibit
switch# show flogi database INTERFACE VSAN FCID PORT NAME NODE NAME fc1/1 1 0x010100 10:00:00:00:c9:29:3b:21 20:00:00:00:c9:29:3b:21 fc1/2 1 0x010200 10:00:00:00:c9:29:3b:22 20:00:00:00:c9:29:3b:22
Refer to the exhibit. A new host is connected to interface fc1/3. It is not appearing in the flogi database. The switch is in NPV mode. What is the most likely reason?
⚠ Common exam trap
Candidates often misunderstand NPV port roles, incorrectly thinking that an NP port is used for host connections. In reality, NP ports are for upstream links, while host-facing ports must be F ports.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The interface is configured as an NP port.
In NPV mode, a switch operates as a proxy for FLOGI requests, forwarding them upstream to the core switch. For an interface to accept a host FLOGI, it must be configured as an F port. If the interface is configured as an NP port (which is intended for uplink to the core), it will not accept or forward FLOGI frames from the host. Therefore, the host never appears in the flogi database.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The FCID is already allocated.
Why it's wrong here
FCID allocation is dynamic and would not prevent FLOGI; the switch would assign a new FCID or reject if duplicate.
- ✗
The host's WWPN is already in use by another device.
Why it's wrong here
If the WWPN were in use, the switch would show a FLOGI attempt with an error, not just absence.
- ✓
The interface is configured as an NP port.
Why this is correct
An NP port expects connection to a core switch, not a host; thus hosts cannot log in through it.
- ✗
The interface is in a different VSAN than the host's FLOGI.
Why it's wrong here
The exhibit shows VSAN 1 for all interfaces; if fc1/3 were in a different VSAN, it would still show FLOGI in that VSAN.
- ✗
The host's HBA is not compatible with NPV.
Why it's wrong here
NPV is transparent to hosts; any standard FC HBA works.
