The network board in a workstation is currently configured as follows: Network speed = Auto Duplexing = Auto The workstation is experiencing poor network performance, and you suspect that the network board is not correctly detecting the network speed and duplex settings. Upon investigation, you find that it is running at 10 Mbps half-duplex. You know that your network switch is capable of much faster throughput. To fix this issue, you decide to manually configure these settings on the workstation. Before you do so, you need to verify the configuration of the switch port that the workstation is connected to. Given that it is a Cisco switch, which commands can be used on the switch to show a list of all switch ports and their current settings? (Select two.) -show interface ethernet counters -show running-config interface -show interface switchport -show interface -show interface capabilities

-show interface

You are the network administrator of a branch office of your company. The branch office network is part of a WAN that covers most of the United States. The office has two Windows 2000 servers, two UNIX servers, one Windows NT server, 90 Windows 98 clients, 40 Windows 2000 Professional clients, and five Macintosh clients. Users have been complaining that they are unable to access resources over the WAN at the main headquarters. You suspect that one of the routers between your office and the main headquarters is not working properly. What TCP/IP utility can you use to see if a router is working properly? -netstat -nbtstat -nslookup -tracert

-tracert

Match the EtherChannel protocol on the left with its characteristics on the right. Each protocol may be used once, more than once, or not at all.

Desirable mode places the port in a negotiating state. -Port Aggregation Protocol (PAgP) Based on the 802.3ad standard. -Link Aggregation Control Protocol (LACP) Passive mode places the port into a passive negotiating state. -Link Aggregation Control Protocol (LACP) Auto mode places the port into a passive negotiating state. -Port Aggregation Protocol (PAgP) Active mode places the port in a negotiating state. -Link Aggregation Control Protocol (LACP)

The FastEthernet 0/0 interface on a switch is currently disabled. You need to enable it so a workstation can be connected to it. Drag the command on the left to the appropriate configuration step on the right. It is possible that not all commands are required.

Enter global configuration mode. -conf t Enter interface configuration mode. -int fa0/0 Enable the interface. -no shut Verify that the interface is enabled. -show interface status

You need to configure the FastEthernet 0/1 interface on a switch to automatically detect the appropriate link speed and duplex setting by negotiating with the device connected to the other end of the link. Drag the command on the left to the appropriate configuration step on the right. It is possible that not all of the commands are required

Enter global configuration mode. -conf t Enter interface configuration mode. -int fa0/1 Set the speed of the interface. -speed auto Set the duplex setting for the interface. -duplex auto

What are the main differences between the OSPF and IS-IS routing protocols? -OSPF requires an area 0, while IS-IS does not. -OSPF is an IGP routing protocol, while IS-IS is a BGP routing protocol. -OSPF is a classful protocol, while IS-IS is a classless protocol. -OSPF is a link state protocol, while IS-IS is not.

OSPF requires an area 0, while IS-IS does not.
