This 350-601 practice question tests your understanding of security. 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.
Which two statements are true about Cisco TrustSec? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It requires a Cisco ISE policy server
Cisco TrustSec relies on a Cisco ISE policy server to define and enforce security policies based on Security Group Tags (SGTs). ISE acts as the centralized policy decision point, dynamically assigning SGTs to authenticated endpoints and distributing the SGT-to-IP bindings to network devices via SXP or inline tagging.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
It requires a Cisco ISE policy server
Why this is correct
ISE is the policy server that defines and distributes SGT-based policies.

✗
It requires 802.1X authentication
Why it's wrong here
TrustSec can use MAB or web authentication; 802.1X is not mandatory.
✗
It provides encryption at Layer 2
Why it's wrong here
TrustSec focuses on access control, not encryption; MACsec is separate.
✗
It uses VLANs for segmentation
Why it's wrong here
TrustSec uses SGTs, not VLANs, for segmentation.
✓
It uses SGTs for access control
Why this is correct
TrustSec tags traffic with SGTs and enforces policies based on them.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that TrustSec requires 802.1X or provides mandatory encryption, when in fact 802.1X is just one of several authentication methods and encryption (MACsec) is an optional enhancement.
Detailed technical explanation
How to think about this question
Under the hood, TrustSec assigns an SGT (a 16-bit value) to each packet, which is then used by network devices to enforce access policies based on the source and destination SGT, independent of IP addresses. In a real-world scenario, a hospital can use SGTs to ensure that only devices tagged as 'Nurse_Station' can access patient records, while guest devices tagged as 'Guest' are blocked, all without relying on VLAN reconfiguration.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
