350-701 Practice Question: Secure Network Access, Visibility and Enforcement
Which TWO are valid methods for determining the SGT (Security Group Tag) assigned to an endpoint in a TrustSec deployment?
⚠ Common exam trap
Cisco often tests the distinction between how an SGT is assigned to an endpoint (static on switch or dynamic from ISE) versus how an endpoint learns its own SGT (DHCP Option 141), leading candidates to incorrectly select DHCP Option 141 as a method for the network to determine the SGT.
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
✓
Static assignment on the network access device (switch) using the 'cts role-based sgt' command
The 'cts role-based sgt' command on a network access device (switch) statically assigns an SGT to an endpoint based on its IP address or MAC address. Option E is correct because ISE can dynamically assign an SGT to an endpoint as part of an authorization policy during authentication, using RADIUS attributes like cisco-av-pair=CTS:SGT=value.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
DNS resolution of the endpoint hostname
Why it's wrong here
DNS does not carry SGT information.
- ✓
Static assignment on the network access device (switch) using the 'cts role-based sgt' command
Why this is correct
The switch can be configured with a static SGT per port or per VLAN.
- ✗
The IP address of the endpoint
Why it's wrong here
SGT is identity-based, not IP-based.
- ✗
DHCP Option 141
Why it's wrong here
DHCP Option 141 is for TFTP server address, not SGT.
- ✓
Dynamic assignment from ISE based on authentication or authorization policy
Why this is correct
ISE can assign SGT via RADIUS attributes.
Quick reference
AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
