Refer to the exhibit. According to the show output, which statement is true?

A.
NBAR protocol discovery has been enabled on the router through the use of the match protocol commands within the class-map.

B.
The unknown protocol traffic statistics refer to all the traffic matched by the class-default traffic class.

C.
HTTP is the most active protocol on the Fa0/0 interface based on byte count.

D.
The 5-minute average bits-per-second rate for all traffic entering the Fa0/0 interface is 398 kbps.

E.
There is a total of 39,990 NetBIOS packets exiting the Fa0/0 interface.

Explanation:

The first step in being able to classify network traffic is to actually know what protocols and applications are running on the network. This knowledge enables administrators to prioritize business-critical information and applications over less-important applications. Unfortunately, to configure ACLs to classify network traffic you must have prior knowledge of the network applications, as well as their associated protocol or port numbers. One option for discovering the protocols currently traversing an interface within the network is using NBAR protocol discovery. NBAR is capable of recognizing any protocol included within the PDLM file. Protocol discovery is applied to the desired interface or group of interfaces using the following command at each intended interface:

ip nbar protocol-discovery

When protocol discovery is applied to the interface, statistics are gathered depicting the active protocols traversing the interface. To view the results of the protocol discovery process, use the following command:

show ip nbar protocol-discovery [ interface type num ]
