A. TACACS+ server
B. Single sign-on
C. SYSLOG server
D. Wi-Fi analyzer

Correct Answer: C

Explanation:
Syslog is a protocol designed to send log entries generated by a device or process called a facility across an IP network to a message collector, called a syslog server. A syslog message consists of an error code and the severity of the error. A syslog server would enable the network administrator to view device error information from a central location.
