- A
EISL trunking
EISL trunking enables multiple VSANs over a single ISL.
- B
NPV mode
Why wrong: NPV is for edge switch scaling, not trunking multiple VSANs.
- C
PortChannel
Why wrong: PortChannel aggregates multiple links, but does not inherently carry multiple VSANs on a single link.
- D
VSAN-based zoning
Why wrong: Zoning controls access, not trunking.

350-601 Storage Network Practice Question
This 350-601 practice question tests your understanding of storage network. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A Cisco MDS switch is connected to another MDS via a Fibre Channel link. The two switches need to carry traffic for multiple VSANs over a single physical link. Which feature should be configured?
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
✓
EISL trunking
EISL (Enhanced ISL) allows multiple VSANs to be trunked over a single ISL.
Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
EISL trunking
Why this is correct
EISL trunking enables multiple VSANs over a single ISL.
Related concept
Access ports place end devices into a single VLAN.
- ✗
NPV mode
Why it's wrong here
NPV is for edge switch scaling, not trunking multiple VSANs.
- ✗
PortChannel
Why it's wrong here
PortChannel aggregates multiple links, but does not inherently carry multiple VSANs on a single link.
- ✗
VSAN-based zoning
Why it's wrong here
Zoning controls access, not trunking.
Common exam traps
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Detailed technical explanation
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.
Key takeaway
A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
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.
What to study next
Got this wrong? Here's your next step.
Review VLAN allowed lists, native VLAN mismatch detection, and how to verify VLAN membership with show vlan brief and show interfaces trunk. Then practise related 350-601 questions on switching, trunking, and access-port configuration.
