A. B. C. D.B
The configuration in the exhibit is associated with the policing component of class of service (CoS) in Junos OS.
The "if-exceeding" statement is a term that is applied to a firewall filter, which is then used as a policing action for a specific CoS. The firewall filter is applied to the incoming traffic, and if the traffic matches the filter's criteria and exceeds the bandwidth limit specified (1 Mbps in this case), it will be policed, or dropped, as specified by the "then discard" statement.
The "bandwidth-limit" statement specifies the maximum allowable bandwidth for the traffic that matches the filter's criteria, while the "burst-size-limit" statement sets the maximum size of burst traffic that is allowed to exceed the bandwidth limit.
To summarize, the configuration in the exhibit applies a firewall filter as a policing action to a specific CoS, which sets a bandwidth limit and burst size limit for the traffic that matches the filter's criteria, and drops any traffic that exceeds those limits. Therefore, the correct answer is B. policing.
