Refer to the exhibit. You have noticed that several users in the network are consuming a great deal of bandwidth for the peer-to-peer application Kazaa2. You would like to limit this traffic， and at the same time provide a guaranteed 100 kb/s bandwidth for one of your servers. After applying the configuration in the exhibit， you notice no change in the bandwidth utilization on the serial link； it is still heavily oversubscribing the interface. What is the cause of this problem？（）
A.CEF needs to be enabled for NBAR
B.In class Kazaa2， you should configure a policer instead of a drop command.
C.The server class should have a priority of 100.
D.The bandwidth parameter on serial 0/0 is wrong.
E.Kazaa2 is not a valid protocol.
Refer to the exhibit. Users from the Engineering VLAN complain that every time Business VLAN users have a network connectivity issue，the Engineering VLAN users usually have problems experiencing slow response or network connectivity problems. After troubleshooting， anunauthorized switch 2 was found.This unauthorized switch has been a regular problem， assuming the root bridge function under thespanning-tree domain and causing the Engineering VLAN to be unstable. Which three of these actionscould be suggested to fix the problem？（）
A.Upgrade Spanning Tree Protocol to Rapid Spanning Tree Protocol.
B.Change Business VLAN PCs to switch 1 and switch 4.
C.Force the root bridge to be switch 2， instead.
D.Adjust spanning-tree timers （max-age and forward-delay）.
E.Shut down all unused ports.
F.Use MSTP to separate the Engineering VLAN from the Business VLAN to optimize spanning-tree convergence time within each VLAN.
Refer to the exhibit. As a network administrator， you have configured a dual-rate， dual-bucket policer in accordance with RFC 2698 on the serial interface of you router， connecting to your provider. The SLA with your provider states that you should only send AF31 （limited to 150 kb/s）， AF32 （limited to 50 kb/s）and AF33 （best effort）. Your service provider claims you are not conforming to the SLA.Which two things are wrong with this configuration？ （）
A.The configuration of a service policy on half-duplex Ethernet interfaces is not supported.
B.The class class-default sub-command of the policy-map limit command should be set to the DSCP default.
C.The violate action is wrong.
D.This policer configuration is not implementing RFC 2698 dual-bucket， dual-rate.
E.The policer is configured in the wrong class.
Refer to exhibits 1 and 2. A company uses a Metro Ethernet （Gigabit Ethernet） dedicated circuit to communicate between users （subnet B） and servers （subnet A） as shown in Exhibit 1. Both routers use OSPF to advertise the subnets. During a weekly management meeting， they realize that the WAN link is oversize. They have been using only 2 Mb/s in the worst-case scenario. So they propose a new， cheaper WAN connection using a 2-Mb/s Frame-Relay point-to-point link to interconnect both sites （Exhibit 2）. The Frame Relay service provider informs them that multicast traffic is not allowed to run over the service provider network. Which one of these options is best to enable the company to establish the OSPF neighbor adjacency？（）
A.Use OSPF network broadcast，because it uses unicast to establish a neighbor relationship.
B.Use OSPF network point-to-multipoint，because it uses unicast to establish a neighbor relationship.
C.Use OSPF network point-to-point，because it uses unicast to establish a neighbor relationship.
D.Use OSPF network point-to-multipoint nonbroadcast，because it establishes a neighbor relationship using unicast packets.
E.Use OSPF network nonbroadcast，because it establishes a neighbor relationship using multicast.

Refer to the exhibit. When applying this policy map on the tunnel1 interface， you see packet loss for the TCP class starting at around 100000 b/s， instead of the configured 150000 b/s. What is the most likely cause of the discrepancy？（）
A.The violate-action command should not be configured.
B.The current configuration of the load-interval command on the tunnel interface is preventing proper policing calculations.
C.The burst size is too low.
D.Policing on tunnel interfaces is not supported.
E.The CIR keyword is missing in the policer.
