Switch is trying to authenticate to the tacacs server via wrong interface. Now it has right interface. In the context of the question, it is asking if you remember the configuration command correctly.

Selected Answer: C

The only valid command is "C" -> "ip tacacs source-interface". Still, I do not think that I would solve the issue.

This command does not solve the authentication issue. It only helps to troubleshoot, and makes log analyzes easier. https://www.oreilly.com/library/view/cisco-ios-cookbook/0596527225/ch04s08.html
