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.
2 Passwords can be
used to restrict access to all or parts of the Cisco IOS. Select the modes and
interfaces that can be protected with passwords. (Choose three.)
VTY interface
console interface
Ethernet interface
secret EXEC mode
privileged EXEC mode
router configuration mode
3 Which two
statements correctly describe the components of a router? (Choose two.)
RAM permanently stores the configuration file used during
the boot sequence.
ROM contains diagnostics executed on hardware modules.
NVRAM stores a backup copy of the IOS used during the boot
sequence.
Flash memory does not lose its contents during a reboot.
ROM contains the most current and most complete version of
the IOS.
Flash contains boot system commands to identify the location
of the IOS
4 Which are functions of a router? (Choose three.)
packet switching
extension of network segments
segmentation of broadcast domains
selection of best path based on logical addressing
election of best path based on physical addressing
5 What is the outcome of entering these commands?
R1(config)# line vty 0 4 R1(config-line)# password check123
R1(config-line)# login
ensures that a password is entered before entering user EXEC
mode
sets the password to be used for connecting to this
router via Telnet
requires check123 to be entered before the configuration can
be saved
creates a local user account for logging in to a router or
switch
6 . Which of the following is the correct flow of routines
for a router startup?
load bootstrap, load IOS, apply configuration
load bootstrap, apply configuration, load IOS
load IOS, load bootstrap, apply configuration, check
hardware
check hardware, apply configuration, load bootstrap, load
IOS
7 What three processes does a router execute when it
receives a packet from one network that is destined for another network?
(Choose three.)
decapsulates the Layer 3 packet by stripping off the
Layer 2 frame header
uses the destination MAC Address in the IP Header to look up
the next-hop address in the routing table
leaves the Layer 2 frame header intact when decapsulating
the Layer 3 packet
uses the destination IP Address in the IP header to look
up the next-hop address in the routing table
encapsulates the Layer 3 packet into the new Layer 2
frame and forwards it out the exit interface
encapsulates the Layer 3 packet into a special Layer 1 frame
and forwards it to the exit interface
8 The network administrator needs to connect two routers
directly via their FastEthernet ports. What cable should the network
administrator use?
straight-through
rollover
cross-over
serial
9 Which two statements describe characteristics of load
balancing? (Choose two.)
Load balancing occurs when a router sends the same packet to
different destination networks.
Load balancing occurs when a router sends the same packet to
different destination networks.
Load balancing allows a router to forward packets over
multiple paths to the same destination network.
Unequal cost load balancing is supported by EIGRP.
If multiple paths with different metrics to a destinations
exist, the router cannot support load balancing.
10 What information
about the router and its startup process can be gathered from the output of the
show version command? (Choose three.)
the last restart method
the command buffer contents
the amount of NVRAM and FLASH used
the configuration register settings
the location from where the IOS loaded
11 Which interfaces in the exhibit could be used for a
leased line WAN connection? (Choose two.)
1
2
3
4
5
6
12 From what location
can a router load the Cisco IOS during the boot process? (Choose two.)
RAM
TFTP server
NVRAM
setup routine
Flash memory
terminal
13 A network
administrator has just entered new configurations into Router1. Which command
should be executed to save configuration changes to NVRAM?
Router1# copy running-config flash
Router1(config)# copy running-config flash
Router1# copy running-config startup-config
Router1(config)# copy running-config startup-config
Router1# copy startup-config running-config
Router1(config)# copy startup-config running-config
14 What is the
default sequence for loading the configuration file?
NVRAM, FLASH, ROM
FLASH, TFTP,CONSOLE
NVRAM, TFTP, CONSOLE
FLASH, TFTP, ROM
15 What header
address information does a router change in the information it receives from an
attached Ethernet interface before information is transmitted out another
interface?
only the Layer 2 source address
only the Layer 2 destination address
only the Layer 3 source address
only the Layer 3 destination address
the Layer 2 source and destination address
the Layer 3 source and destination address
