CCNA 1 R&S Introduction to Networks Chapter 6 QUIZ

1 Which feature on a Cisco router permits the forwarding of traffic for which there is no specific route?

next-hop
gateway of last resort *
route source
outgoing interface

2 Which value, that is contained in an IPv4 header field, is decremented by each router that receives a packet?

Differentiated Services
Fragment Offset
Header Length
Time-to-Live *

3 What are two functions that are provided by the network layer? (Choose two.)

carrying data between processes that are running on source and destination hosts
providing end devices with a unique network identifier *
placing data on the network medium
directing data packets to destination hosts on other networks *
providing dedicated end-to-end connections

4 How does the network layer use the MTU value?

The network layer depends on the higher level layers to determine the MTU.
The network layer depends on the data link layer to set the MTU, and adjusts the speed of transmission to accommodate it.
The MTU is passed to the network layer by the data link layer *
To increase speed of delivery, the network layer ignores the MTU.

5 When transporting data from real-time applications, such as streaming audio and video, which field in the IPv6 header can be used to inform the routers and switches to maintain the same path for the packets in the same conversation?

Next Header
Flow Label *
Traffic Class
Differentiated Services

6 What is the command netstat -r used for?

to display the TCP sockets
to renew the default gateway
to release the assigned IP address
to display the host routing table *

7 A packet arrives at a router interface. The router goes through a series of steps to determine where the packet should be forwarded. Place the steps of the router forwarding process in the correct order. (Not all options are used.)

1 -> examine packet header

2 -> determine destination network

3 -> examine routing table

4 -> identify exit interface to destination from route entry

5 -> move packet to forwarding interface

8 During troubleshooting procedures, from which location will most Cisco routers load a limited IOS?

NVRAM
RAM
ROM *
flash

9 During the boot process, in what memory location will the router bootstrap program look for the IOS image if a TFTP server is not used?

flash *
NVRAM
RAM
ROM

10 Which two files are loaded into RAM by the router when it boots? (Choose two.)

running configuration
bootstrap program
startup configuration *
POST
IOS image *

11 Which router bootup sequence is correct?​

1 – perform the POST and load the Cisco IOS software
2 – locate and load the startup configuration file or enter setup mode
3 – locate and load the bootstrap program

1 – perform the POST and load the bootstrap program
2 – locate and load the startup configuration file or enter setup mode
3 – locate and load the Cisco IOS software​

1 – perform the POST and load the startup configuration file
2 – locate and load the bootstrap program
3 – locate and load the Cisco IOS software​

1 – perform the POST and load the bootstrap program
2 – locate and load the Cisco IOS software
3 – locate and load the startup configuration file or enter setup mode *

12 Match the commands to the correct actions. (Not all options are used.)

provides security on the console ->  Router(config-line)#password class

displays a message when the router is accessed ->  Router(config)#banner motd

configures a name on the router -> Router(config)#hostname CL1

13 Open the PT Activity. Perform the tasks in the activity instructions and then answer the question or complete the task.

Which interfaces in each router are active and operational?

R1: G0/0 and S0/0/0
R2: G0/0 and S0/0/0

R1: G0/1 and S0/0/1
R2: G0/0 and S0/0/1

R1: G0/0 and S0/0/0
R2: G0/1 and S0/0/0*

R1: G0/0 and S0/0/1
R2: G0/1 and S0/0/1

14 Within a production network, what is the purpose of configuring a switch with a default gateway address?

Hosts that are connected to the switch can use the switch default gateway address to forward packets to a remote destination.
A switch must have a default gateway to be accessible by Telnet and SSH.
The default gateway address is used to forward packets originating from the switch to remote networks.*
It provides a next-hop address for all traffic that flows through the switch.
