Question 200
A Cisco ISE operations team investigates this site issue: A campus wants finance and research roles separated across multiple VLANs and subnets without maintaining IP-specific ACLs on every access switch. What result should be documented before closing the issue?
Explanation
Correct Answer
A finance endpoint is assigned the correct SGT and the supported enforcement point blocks prohibited research access. The required remediation is: Assign suitable Security Group Tags in ISE and apply group-based Cisco TrustSec enforcement using supported security group ACL policies. It works because trustSec labels traffic with logical security group identity so enforcement can follow roles rather than changing IP addressing.
Incorrect Answers
Create a controlled static IP-to-SGT mapping for the approved server and distribute it through the supported method. The repeat risk here is different: Assign suitable Security Group Tags in ISE and apply group-based Cisco TrustSec enforcement using supported security group ACL policies. A directly relevant preventive control is: A finance endpoint is assigned the correct SGT and the supported enforcement point blocks prohibited research access.
Reauthenticate the session using supported CoA or session refresh and verify the resulting TrustSec authorization. The repeat risk here is different: Assign suitable Security Group Tags in ISE and apply group-based Cisco TrustSec enforcement using supported security group ACL policies. A directly relevant preventive control is: A finance endpoint is assigned the correct SGT and the supported enforcement point blocks prohibited research access.
Register the printer's endpoint MAC as an authorized internal endpoint and configure a tightly scoped MAB authorization profile. The repeat risk here is different: Assign suitable Security Group Tags in ISE and apply group-based Cisco TrustSec enforcement using supported security group ACL policies. A directly relevant preventive control is: A finance endpoint is assigned the correct SGT and the supported enforcement point blocks prohibited research access.
