If RouterC receives a packet that is destined for 10.5.1.1, it will be forwarded out interface Fa0/0.
* If RouterA receives a packet that is destined for 192.168.3.146, it will be forwarded out interface S0/0/1.
* If RouterB receives a packet that is destined for 10.5.27.15, it will be forwarded out interface S0/0/1.
If RouterB receives a packet that is destined for 172.20.255.1, it will be forwarded out interface S0/0/0.
If RouterC receives a packet that is destined for 192.16.5.101, it will be forwarded out interface S0/0/1.
10.
The serial connection shown in the graphic needs to be configured. Which configuration commands must be made on the Sydney router to establish connectivity with the Melbourne site? (Choose three.)
* Sydney(config-if)# ip address 201.100.53.2 255.255.255.0
* Sydney(config-if)# no shutdown
Sydney(config-if)# ip address 201.100.53.1 255.255.255.224
* Sydney(config-if)# clock rate 56000
Sydney(config-if)# ip host Melbourne 201.100.53.2
11.
Refer to the exhibit. What can be concluded from the output of the running-configuration of a router?
The passwords are encrypted.
The current configuration was saved to NVRAM.
The configuration that is shown will be the one used on the next reboot.
* The commands that are displayed determine the current operation of the router.
12.
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
destination IP address: 192.168.10.33
* destination IP address: 192.168.10.134
* destination MAC address: 9999.DADC.1234
13. 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
14. 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
15. 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
16. 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
17. 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.
18. 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
19.
Which interfaces in the exhibit could be used for a leased line WAN connection? (Choose two.)
* 1
2
3
* 4
5
6
20. 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
21. 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
22. What is the default sequence for loading the configuration file?
NVRAM, FLASH, ROM
FLASH, TFTP,CONSOLE
* NVRAM, TFTP, CONSOLE
FLASH, TFTP, ROM
23. 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
