Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 345

During a 802.1X deployment, an engineer must identify failed authentications without causing problems for the connected endpoint. Which command will successfully achieve this?

Answer options

• A. authentication open
• B. dot1x pae authenticator
• C. authentication port-control auto
• D. dot1x system-auth-control

Correct answer: A

Explanation

The command 'authentication open' allows the port to remain open while still logging any authentication failures, thus not interrupting the connected endpoint. The other options either enable or configure authentication without providing the same level of visibility into failed authentications without impacting connectivity.
