Refer to the exhibit. Which statement about the given configuration is true?
A.
The timeout command causes the device to move to the next server after 20 seconds of TACACS
inactivity.
B.
The single-connection command causes the device to process one TACACS request and then
move to the next server.
C.
The single-connection command causes the device to establish one connection for all TACACS
transactions.
D.
The router communicates with the NAS on the default port, TCP 1645
Explanation:
In order for TACACS+ servers to fail over, they must be configured in a TACACS server
group, which these are not, which eliminates A and B. D is incorrect.
“The single-connection keyword specifies a single connection. Rather than have the router open and close a TCP connection to the server each time it must communicate, the single-connection option maintains a single open connection between the router and the server. The single connection is more efficient because it allows the server to handle a higher number of TACACS operations.”
