Implementing Cisco Secure Access Solutions (SISAS, legacy) — Question 9

Which command is useful when troubleshooting AAA Authentication between a Cisco router and the AAA server?

Answer options

• A. test aaa-server test cisco cisco123 all new-code
• B. test aaa group7 tacacs+ auth cisco123 new-code
• C. test aaa group tacacs+ cisco cisco123 new-code
• D. test aaa-server tacacs+ group7 cisco cisco123 new-code

Correct answer: C

Explanation

The correct command, 'test aaa group tacacs+ cisco cisco123 new-code', is specifically designed to validate AAA authentication against a TACACS+ server. The other options either reference incorrect parameters or groups that do not apply in this context, making them unsuitable for troubleshooting AAA authentication issues.
