This 350-601 practice question tests your understanding of 350-601 exam topics. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
An engineer wants to enforce security policies in a data center based on user identity rather than IP addresses. Which Cisco technology enables identity-based tagging and policy enforcement?
VLAN ACLs
Why wrong: VLAN ACLs are IP-based.
ACI micro-segmentation
Why wrong: ACI uses EPGs, not SGTs.
Cisco TrustSec
TrustSec uses SGTs for identity-based tagging and policy.
Nexus port security
Why wrong: Port security is MAC-based, not identity-based.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cisco TrustSec
Cisco TrustSec uses SGTs to tag traffic based on user/device identity, and SGACLs enforce policies.
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
For each option: why learners choose it and why it is or isn't the right answer here.
VLAN ACLs
Why it's wrong here
VLAN ACLs are IP-based.
ACI micro-segmentation
Why it's wrong here
ACI uses EPGs, not SGTs.
Cisco TrustSec
Why this is correct
TrustSec uses SGTs for identity-based tagging and policy.
Related concept
Access ports place end devices into a single VLAN.
Nexus port security
Why it's wrong here
Port security is MAC-based, not identity-based.
Common exam traps
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
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.
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
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
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.
