350-601 Security Practice Question
Which TWO statements about Cisco TrustSec in a data center are true?
⚠ Common exam trap
Cisco often tests the distinction between SGT size (16-bit vs 32-bit) and the role of SXP as a propagation mechanism for non-inline devices, leading candidates to confuse SGT values with other metadata or assume TrustSec replaces authentication protocols like 802.1X.
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
✓
SXP (SGT Exchange Protocol) is used to propagate SGTs across network devices that do not support inline tagging.
SXP (SGT Exchange Protocol) is specifically designed to propagate Security Group Tag (SGT) information between network devices that do not support hardware-based inline tagging (e.g., older switches or routers). SXP allows these devices to participate in TrustSec policy enforcement by exchanging SGT-to-IP bindings over TCP, enabling consistent access control across heterogeneous environments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
TrustSec can replace 802.1X authentication in the data center.
Why it's wrong here
TrustSec complements 802.1X, does not replace it.
- ✗
SGTs are 32-bit values assigned to users or devices.
Why it's wrong here
SGTs are 16 bits (0-65535).
- ✓
SXP (SGT Exchange Protocol) is used to propagate SGTs across network devices that do not support inline tagging.
Why this is correct
SXP allows SGT propagation without hardware support.
- ✗
TrustSec is primarily designed for wireless networks.
Why it's wrong here
TrustSec is used in wired and wireless, but not primarily wireless.
- ✓
TrustSec uses Security Group Tags (SGTs) to enforce access control policies.
Why this is correct
SGTs are the basis for TrustSec policy enforcement.
