Refer to the exhibit.

A network operator uses TACACS for authentication and authorization. While troubleshooting a
NetFlow problem, the operator was requested by Cisco TAC to get the output of show techsupport netflow. The exhibit shows that the command failed with a message “% This command is
not authorized.” The operator is logged into the router with privilege 15 user account defined in
TACACS. What is the most likely reason for this?

A.
The router is missing a software package information envelope (PIE) necessary for NetFlow.

B.
NetFlow is not configured on the router.

C.
The operator has to log into the router by using a local username.

D.
The usergroup priv15 command is not configured properly.

E.
show tech-support netflow is not a supported command.
