Refer to the exhibit. The frame shown in the exhibit was received by the router. The router interfaces are operational. How will the router process this frame? (Choose two.)

The router will change the source and destination IP address in the packet before forwarding the frame.

The router will change the frame type to one supported by the WAN link before forwarding the frame.

The router will use the destination MAC address to determine which interface to forward the packet.

The router will look up the MAC address of the S0/0/0 interface in the ARP table and add it to the frame before forwarding.

The frame was received on the Fa0/0 interface of the router and will be switched to the S0/0/0 interface.

5. 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

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. 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.

 

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

12. 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.

 

13. Which are functions of a router? (Choose three.)

packet switching

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

 

16. 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

Refer to the exhibit. All routers have a route in its routing table to each network that is shown in the exhibit. Default routes have not been issued on these routers. What can be concluded about how packets are forwarded in this network? (Choose two.)

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.

Refer to the exhibit. After host 2 is connected to the switch on the LAN, host 2 is unable to communicate with host 1. What is the cause of this problem?

The subnet mask of host 2 is incorrect.

Host 1 and host 2 are on different networks.

The switch needs an IP address that is not configured.

The router LAN interface and host 1 are on different networks.

The IP address of host 1 is on a different network than is the LAN interface of the router.

21. 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.

 

22. 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.
