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 routerwill monitor local traffic to determine routing protocol configuration requirements.

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 mode3

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

theLayer 3 source and destination address


4

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 frameheader 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

Refer to the exhibit.Host A pings host B. When R4 accepts the ping into the Ethernet interface, what two pieces of header information are included? (Choose two.)

source IP address: 192.168.10.129

source IP address: BBBB.3333.5677

source MAC address: 5555.AAAA.6666

destination IP address: 192.168.10.33

destination IP address: 192.168.10.134

destination MAC address: 9999.DADC.1234


6Refer to the exhibit. What can be concluded from the routing table output in the exhibit? (Choose two.)

This router only has two interfaces.

The router interfaces are not operational yet.

This router is configured to forward packets to remote networks.

The FastEthernet0/0 and Serial0/0/0 interfaces of this router were configured with an IP address and the no shutdown command.An IP packet received by this router with a destination address of 198.18.9.1 will be forwarded out of the Serial0/0/0 interface.

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 notworking. 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.


8

From what location can a router load the Cisco IOS during theboot process? (Choose two.)

RAM

TFTP server

NVRAM

setup routine

Flash memory

terminal


9

What is the default sequence for loading the configuration file?

NVRAM, FLASH, ROM

FLASH, TFTP,CONSOLE

NVRAM, TFTP, CONSOLE

FLASH, TFTP, ROM
