This 350-601 practice question tests your understanding of 350-601 exam topics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 storage administrator needs to isolate Fibre Channel traffic between two departments in a data center using a single MDS switch. The administrator decides to create separate VSANs. Which statement about VSANs is true?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VSANs provide isolation similar to VLANs in Ethernet networks.
VSANs provide isolation similar to VLANs in Ethernet. Each VSAN has its own fabric services and does not share traffic with other VSANs.
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.
✗
VSANs share the same fabric services across all VSANs.
Why it's wrong here
Each VSAN has its own fabric services.
✓
VSANs provide isolation similar to VLANs in Ethernet networks.
Why this is correct
VSANs create separate logical Fibre Channel fabrics on the same physical infrastructure.
Related concept
Access ports place end devices into a single VLAN.
✗
VSANs require separate physical interfaces for each VSAN.
Why it's wrong here
VSANs can be assigned to the same physical interface using trunking (EISL).
✗
VSANs cannot be used with FCoE.
Why it's wrong here
VSANs can be used with FCoE as well.
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.
Access ports place end devices into a single VLAN.
What is the correct answer to this question?
The correct answer is: VSANs provide isolation similar to VLANs in Ethernet networks. — VSANs provide isolation similar to VLANs in Ethernet. Each VSAN has its own fabric services and does not share traffic with other VSANs.
What should I do if I get this 350-601 question wrong?
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.
What is the key concept behind this question?
