How much web traffic can RouterA send out the FastEthernet0/1 interface during periods of heavy voice and video traffic? (Select the best answer.)

• 350-401 : All Parts

1.Define one or more class maps by issuing the classmap name command.
2.Define the traffic that matches the class map by issuing one or more match commands.
3.Define one or more policy maps by issuing the policymap name command.
4.Link the class maps to the policy maps by issuing the classname command.
5.Define one or more actions that should be taken for that traffic class.
6.Link the policy map to an interface by issuing the servicepolicy {input | output} name command.

Bandwidth guarantees are set in policymap class configuration mode. You can specify the bandwidth as a rate or as a percentage with the bandwidth and priority commands. The syntax of the priority command is priority {bandwidth | percentpercentage} [burst], where bandwidth is specified in Kbps and burst is specified in bytes. The prioritycommand creates a strictpriority queue where packets are dequeued before packets from other queues are dequeued. The strictpriority queue is given priority over all other traffic.
If no priority traffic is being sent, the other traffic classes can share the remainingbandwidth based on their configured values.
The bandwidth command specifies a guaranteed amount of bandwidth for a particular traffic class. The syntax of the bandwidth command is bandwidth {kbps | remaining percentpercentage | percentpercentage}, where kbps is the amount of bandwidth that is guaranteed to a particular traffic class.
In this scenario, Voice over IP (VoIP) traffic is given a guaranteed 20 percent of the interface’s bandwidth. Video traffic is given a guaranteed 40 percent of the interface’s bandwidth. Voice and video traffic can exceed these bandwidth percentages if any unused bandwidth remains.
The remaining 40 percent, or 40 Mbps, of the interface’s bandwidth can be used by other traffic. If traffic does not match any traffic class, it will become part of the classdefault class. In this scenario, web traffic belongs to the classdefault class. Therefore, web traffic can consume 25 percent of the remaining bandwidth. If no other traffic is being sent on the interface, web traffic can consume 25 percent of the interface’s bandwidth. However, when voice and video traffic are heavy, web traffic can consume 25 percent of the remaining 40 Mbps, which is equal to 10 Mbps.
Even less web traffic can be sent if File Transfer Protocol (FTP) traffic or other unclassifiedtraffic is heavy. FTP traffic can consume 50 percent of the remaining bandwidth on the interface. If no other traffic is being sent on the interface, FTP traffic can consume 50 percent of the interface’s bandwidth. During periods of heavy voice and video usage, FTP traffic can consume 50 percent of the remaining 40 Mbps, which is equal to 20 Mbps.
