1. If boot system commands have been configured, which of the following could happen if a router fails to obtain an IOS image from the primary sources during bootup?

The router will load a subset of a full IOS version from system ROM.

The router will attempt to reboot two times before failing.

The router will load the last good IOS image from NVRAM.

The administrator will be prompted to load a valid IOS image.

config-image

config-system

config-register

config-bootfield

config system bootstrap

1. Which keystrokes can be used to return to the privileged mode from the interface configuration mode?

Ctrl-P

Ctrl-Shift-6, then X

Ctrl-Z

Esc

2. Which connection method can be used to perform the initial configuration of a router?

use a serial connection of a computer connected to the console port of a router

telnet to the router through a serial port

use a vty port through the Ethernet interface

use a modem connected to the AUX port of the router

1. Which of the following devices are used in the construction of a WAN? (Choose three.)

hubs

routers

communication servers

transceivers

modems

multi-port repeaters

2. Which basic components do a router and a standard desktop PC have in common? (Choose three.)

1. When a network administrator applies the subnet mask 255.255.255.248 to a Class A address, for any given subnet, how many IP addresses are available to be assigned to devices?

1022

510

254

126

30

6

2. What is the maximum distance that 10BASE-T will transmit data before signal attenuation affects the data delivery?

100 meters

185 meters

300 meters

500 meters

1. A router determines the path to deliver a packet. What layer of the OSI model does this fact represent?

session

transport

network

data link

physical

2.

 
Refer to the exhibit. A network administrator has configured a network after subnetting the network number 192.168.0.0/28. Workstation 1 is not able to communicate with Workstation 2. What is the cause of this loss in communications?

Workstation 1 and Workstation 2 are on the same subnet.

The serial connections are using addresses from the LAN subnets.

Workstation 1 is not on the same network that the Router 1 LAN interface is on.

If routers are used in the network, IP addresses do not need to be subnetted.

1. Which layer of the OSI model can provide a connection-oriented, reliable data transfer between two hosts?

Application

Presentation

Session

Transport

2. Which protocol is used to transfer files from computer to computer but is considered connectionless?

FTP

TFTP

SNMP

TCP

DHCP

1. How does a router decide where the contents of a received frame should be forwarded?

by matching destination IP addresses with networks in the routing table

by matching the destination IP address with IP addresses listed in the ARP table

by matching the destination MAC address with MAC addresses listed in the CAM table

by forwarding the frame to all interfaces except the interface on which the frame was received

2. Which device would add security to a network by not forwarding broadcasts?

hub

router

switch

bridge

repeater

1.

Refer to the exhibit. Which two statements are correct in reference to the output shown? (Choose two.)

The LAN segment is subnetted to allow 254 subnets.

The DNS server for this host is on the same subnet as the host.

The host automatically obtained the IP addresses 192.168.1.100.

The host received the IP address from a DHCP-enabled device on the local LAN segment.

The host is assigned an address of 00-50-8D-F1-EA-8D by the administrator.

2.

Refer to the exhibit. The small office LAN shown in the exhibit may eventually be connected to the Internet. According to Cisco best practice, which IP network addresses should be used?

12.0.0.0

172.0.0.0

172.168.0.0

192.32.17.0

192.168.67.0

225.1.5.0
