Which three sets of commands are required to enable administrators to connect to a switch on the same LAN via Telnet for configuration and management? (Choose three.) Switch1(config)# interface fa0/1 Switch1(config-if)# ip address 192.168.2.64 255.255.255.192 Switch1(config)# interface fa0/1 Switch1(config-if)# switchport port-security Switch1(config)# interface vlan 1 Switch1(config-if)# ip address 192.168.2.126 255.255.255.192 Switch1(config-if)# no shutdown Switch1(config)# line con 0  Switch1(config-line)# enable password cisco Switch1(config-line)# login Switch1(config)# line vty 0 15 Switch1(config-line)# password cisco Switch1(config-line)# login Switch1(config)# enable secret class Switch1(config)# exit

Refer to the exhibit. A company always uses the last valid IP address in a subnetwork as the IP address of the router LAN interface. A network administrator is using a laptop to configure switch X with a default gateway via the switch console port. The switch VLAN 1 interface is assigned IP address 192.168.5.68/26. What command will the administrator use to assign a default gateway to the switch? X(config)# ip default-gateway 192.168.5.1 X(config)# ip default-gateway 192.168.5.126 X(config)# ip default-gateway 192.168.5.190 X(config)# ip route 0.0.0.0 0.0.0.0 192.168.5.192 X(config)# ip route 192.168.5.0 255.255.255.192 192.168.5.1

A network technician is attempting to add an older workstation to a Cisco switched LAN. The technician has manually configured the workstation to full-duplex mode in order to enhance the network performance of the workstation. However, when the device is attached to the network, performance degrades and excessive collisions are detected. What is the cause of this problem? The host is configured in a different subnet from the subnet of the switch. There is a duplex mismatch between the workstation and switch port. The switch port is running at a different speed from the speed of the workstation NIC. The host has been configured with a default gateway that is different from that of the switch.

13

In what two ways does SDM differ from the IOS CLI? (Choose two.) SDM is used for in-band management only. The IOS CLI can be used for in-band and out-of-band management. SDM is accessed through a Telnet application. The IOS CLI is accessed through a web browser. SDM is available for all router platforms. The IOS CLI is available for a limited number of Cisco devices. SDM utilizes GUI buttons and text boxes. The IOS CLI requires the use of text-based commands. SDM is used for advanced configuration tasks. The IOS CLI is preferred for initial basic device configuration.

14	When utilizing SDM Express, which two configuration options allow a router serial interface to obtain an IP address without manually configuring it? (Choose two.) Static IP Address Frame Relay encapsulation IP Negotiated HDLC encapsulation IP Unnumbered

Refer to the exhibit. From the router console, an administrator is unable to ping a Catalyst switch that is located in another building. What can the administrator do from her location to check the IP configuration of the attached switch? Open an SDM session with the switch from her desktop. Telnet to the switch from the router console. Use the show cdp neighbors detail command from the router console. The administrator must go to the switch location and make a console connection to check these settings.
