A client connects to a network and the authenticator device learns the MAC address 11:22:33:44:55:AA of this client. After the MAC address is learned, the 802.1 x authentication process begins on this port.
Which ISE deployment mode restricts all traffic initially, applies a rule for access control if 802.1x authentication is successful, and can be configured to grant only limited access if 802.1 x authentication is unsuccessful?
- open mode
- monitor mode
- closed mode
- low-impact mode
Answer(s): C
Explanation:
In closed mode, the port is initially in a restricted state, allowing no traffic until the 802.1x authentication process is completed successfully. Once the client passes authentication, access control rules are applied based on policies defined in Cisco ISE. These rules determine the level of access the authenticated client is granted.
