An engineer wants to migrate 802.1x deployment phase from Open to low impact mode.
Which options she select?
A. Ingress access list applied to the interface
B. Authentication host mode to multiple domain
C. Open authentication to the domain
D. Authentication host mode to multiple authentication
Answer: A
Explanation:
Compared to Monitor Mode, Low-Impact Mode incrementally increases the security level of the network by configuring an ingress port ACL on the open access TrustSec-enabled port. This provides basic connectivity for guests, contractors, and unauthenticated hosts while selectively limiting access, introducing a higher level of security. Access can be differentiated based on successful authentication and authorization by combining downloadable access control lists (dACLs) with the TrustSec-enabled port, which uses 802.1X, MAC Authentication Bypass (MAB), and/or web authentication.
A is right
