          bridge priority

          base MAC address

6. If a modem is being used to connect to an ISP, which WAN connection type is being used?

          reported distance of the feasible successor

Configure the access list for the correct network.

20. Which command should a network administrator issue to disable default summarization in an EIGRP network?

Router(config-router)# no auto-summary

21. Refer to the exhibit. What is the purpose of assigning the IP address 192.168.30.1 to an access layer switch?
    
    
    

to allow remote management of the switch

23. Refer to the exhibit. Both routers are configured to use the EIGRP routing protocol. The network administrator wants to enable manual summarization by issuing the displayed command. 
    
    
    
    
    in interface mode on the S0/0/0 interface of R2
24. Refer to the exhibit. What are two possible procedures that would ensure that R1 would always be the DR for OSPF area 0? (Choose two.)
    
    
    

Set the router ID of R1 to the highest IP address in the network.

Set the OSPF priority to 255 on the R1 FastEthernet0/0 interface

25. What is the difference between the passive and active route status as displayed in an EIGRP topology table?

Routes that are active are being recalculated by DUAL.

26. Refer to the exhibit. Which two facts can be determined from the output? (Choose two.)
    

    

    
    

The router ID of R2 is 192.168.100.65.

R2 has established adjacencies with three routers.

27. Refer to the exhibit. Both switches have been configured with static VLANs. Host A and host C belong to one VLAN and host B and D belong to another VLAN. However, the hosts within the same VLAN are unable to communicate with each other.
    
    Which troubleshooting approach should be followed to resolve this problem?
    

    

    
    

Ensure that the ports connecting the two switches are configured as trunk ports.

NAT overload is enabled on router R1.

30. Refer to the exhibit. The RIPv2 routing protocol has been enabled with default options on all routers in the network. A user at IP address 192.168.3.20 attempts to connect to a server at IP address 192.168.3.88 but is unsuccessful. What could be done to correct this situation?
    

    

    
    

Turn off automatic summarization on all routers in the network.

31. Refer to the exhibit. Workstation H1 is unable to reach the Internet. A network technician issues a ping command to troubleshoot the problem. Based on the results of the commands that are shown, what could be the cause of the problem?
    

    

    
    

The default gateway on H1 is incorrect.

32. Refer to the exhibit. Host H2 and host H3 are able to ping the default gateway but cannot ping host H1. Host H1 cannot ping either the default gateway, host H2, or host H3. The network technician issues the show interfaces command on switch S1 and notes that all unused switch ports are administratively down and ports Fa0/1, Fa0/3, and Fa0/4 are up with their line protocol up. However, S1 port Fa0/2 is shown as down with the line protocol down error (disabled). What is a possible cause for the inability of H1 to communicate with the network?
    

    

    
    

Port security on switch S1 port Fa0/2 is misconfigured.
