Refer to the exhibit. Router R1, the DCE device, has just been configured for PPP encapsulation with authentication. What series of commands will allow another router, the DTE device, to communicate over its serial 0/0/0 interface to router R1?

Router(config)# hostname R3
R3(config)# username R1 password Cisco
R3(config)# interface Serial 0/0/0
R3(config-if)# encapsulation ppp
R3(config-if)# ip address 172.16.3.3 255.255.255.0
R3(config-if)# ppp authentication chap

Router(config)# hostname R3
R3(config)# username R3 password Cisco
R3(config)# interface Serial 0/0/0
R3(config-if)# encapsulation ppp
R3(config-if)# ip address 172.16.3.3 255.255.255.0
R3(config-if)# ppp authentication chap

Router (config)# username Router password Cisco
Router (config)# interface Serial 0/0/0
Router (config-if)# clockrate 64000
Router (config-if)# encapsulation ppp
Router (config-if)# ip address 172.16.3.1 255.255.255.0

1. If a network administrator enters these commands on a switch, what will be the result?
Switch1(config-line)# line console 0
Switch1(config-line)# password cisco
Switch1(config-line)# login

to secure the console port with the password "cisco"

to deny access to the console port by specifying 0 lines are available

to gain access to line configuration mode by supplying the required password

to configure the privilege exec password that will be used for remote access

 

2. Which command line interface (CLI) mode allows users to configure switch parameters, such as the hostname and password?

user EXEC mode

privileged EXEC mode

global configuration mode

interface configuration mode

1. If a router cannot find a valid configuration file during the startup sequence, what will occur?

The startup sequence will reset.

The router will prompt the user for a response to enter setup mode.

The startup sequence will halt until a valid configuration file is acquired.

The router will generate a default configuration file based on the last valid configuration.

The router will monitor local traffic to determine routing protocol configuration requirements.

Refer to the exhibit. The network administrator has configured the router with the interface IP addresses shown for the directly connected networks. Pings from the router to hosts on the connected networks or pings between router interfaces are not working. What is the most likely problem?

The destination networks do not exist.

The IP addresses on the router interfaces must be configured as network addresses and not host addresses.

The interfaces must be enabled with the no shutdown command.

Each interface must be configured with the clock rate command.
