Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 200

A client connects to a network and the authenticator device learns the MAC address 04:49:23:86:34:AB 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?

Answer options

• A. open mode
• B. monitor mode
• C. closed mode
• D. low-impact mode

Correct answer: C

Explanation

The correct answer is C, closed mode, as it restricts all traffic by default until successful 802.1x authentication occurs. Options A (open mode) and B (monitor mode) do not restrict traffic initially, while D (low-impact mode) does not provide the same level of traffic restriction as closed mode does.
