Which description of the use of low-impact mode in a Cisco ISE deployment is correct?
A . It continues to use the authentication open capabilities of the switch port, which allows traffic to enter the switch before an authentication result.
B . Low-impact mode must be the final phase in deploying Cisco ISE into a network environment using the
phased approach.
C . The port does not allow any traffic before the authentication (except for EAP, Cisco Discovery Protocol, and LLDP), and then the port is assigned to specific authorization results after the authentication.
D . It enables authentication (with authentication open), sees exactly which devices fail and which succeed, and corrects the failed authentications before they cause any problems.
