CCNA 5.0 (CCNA R&S) – Network Basics Final Exam P1

1

What is the purpose of having a converged network?

to provide high speed connectivity to all end devices

to make sure that all types of data packets will be treated equally

to achieve fault tolerance and high availability of data network infrastructure devices

to reduce the cost of deploying and maintaining the communication infrastructure

Three bank employees are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other corporate managers in branch offices. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types?

audio conference, financial transactions, web page

financial transactions, web page, audio conference

audio conference, web page, financial transactions

financial transactions, audio conference, web page

3

What is a characteristic of end-to-end data transmission in a packet-switched network?

A connection-oriented technology is employed.

A path is pre-determined before the transmission starts.

A file may traverse multiple paths to reach the destination.

A dedicated path is maintained during the transmission period.

4

What is a characteristic of a scalable network?

100% uptime

redundant links

easy expansion

multiple backup devices

5

Refer to the exhibit. Which area would most likely be an extranet for the company network that is shown?

area A

area B

area C

area D

6

A home user is looking for an ISP connection that provides high speed digital transmission over regular phone lines. What ISP connection type should be used?

DSL

dial-up

satellite

cell modem

cable modem

7

During normal operation, from which location do most Cisco switches and routers run the IOS?

RAM

flash

NVRAM

disk drive

8

Which connection provides a secure CLI session with encryption to a Cisco switch?

a console connection

an AUX connection

a Telnet connection

an SSH connection

9

An administrator uses the Ctrl-Shift-6 key combination on a switch after issuing the ping command. What is the purpose of using these keystrokes?

to restart the ping process

to interrupt the ping process

to exit to a different configuration mode

to allow the user to complete the command

10

Refer to the exhibit. An administrator wants to change the name of a brand new switch, using the hostname command as shown. What prompt will display after the command is issued?​

My Switch(config)#​

Switch(config)#​

MySwitch(config)#​

My(config)#​

Switch#

11

Refer to the exhibit. A network administrator is configuring access control to switch SW1. If the administrator uses Telnet to connect to the switch, which password is needed to access user EXEC mode?

letmein

secretin

lineconin

linevtyin

12

 

After making configuration changes, a network administrator issues a copy running-config startup-config command in a Cisco switch. What is the result of issuing this command?

The new configuration will be stored in flash memory.

The new configuration will be loaded if the switch is restarted.

The current IOS file will be replaced with the newly configured file.

The configuration changes will be removed and the original configuration will be restored.

13

On which switch interface would an administrator configure an IP address so that the switch can be managed remotely?

FastEthernet0/1

VLAN 1

vty 0

console 0

14

A technician uses the ping 127.0.0.1 command. What is the technician testing?

the TCP/IP stack on a network host

connectivity between two adjacent Cisco devices

connectivity between a PC and the default gateway

connectivity between two PCs on the same network

physical connectivity of a particular PC and the network

15

Which address on a PC does not change, even if the PC is moved to a different network?

IP address

default gateway address

MAC address

logical address

16

Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

Data is sent from the internet layer to the network access layer.

Packets are sent from the network access layer to the transport layer.

Segments are sent from the transport layer to the internet layer.

Frames are sent from the network access layer to the internet layer.

17

18

What will happen if the default gateway address is incorrectly configured on a host?

The host cannot communicate with other hosts in the local network.

The switch will not forward packets initiated by the host.

The host will have to use ARP to determine the correct address of the default gateway.

The host cannot communicate with hosts in other networks.

A ping from the host to 127.0.0.1 would not be successful.

19

A host PC has just booted and is attempting to lease an address through DHCP. Which two messages will the client typically broadcast on the network? (Choose two.)

DHCPDISCOVER

DHCPOFFER

DHCPREQUEST

DHCPACK

DHCPNACK

20

Refer to the exhibit. A TCP segment from a server has been captured by Wireshark, which is running on a host. What acknowledgement number will the host return for the TCP segment that has been received?

2

21

250

306

2921

21

Which technology provides a solution to IPv4 address depletion by allowing multiple devices to share one public IP address?

ARP

DNS

NAT

SMB

DHCP

HTTP

22

Which function is provided by TCP?

data encapsulation

detection of missing packets

communication session control

path determination for data packets

23

 

What is the purpose of the routing process?

to encapsulate data that is used to communicate across a network

to select the paths that are used to direct traffic to destination networks

to convert a URL name into an IP address

to provide secure Internet file transfer

to forward traffic on the basis of MAC addresses

24

 

Which field in an IPv4 packet header will typically stay the same during its transmission?

Flag

Time-to-Live

Packet Length

Destination Address

25

 

Refer to the exhibit. Consider the IP address configuration shown from PC1. What is a description of the default gateway address?

It is the IP address of the Router1 interface that connects the company to the Internet.

It is the IP address of the Router1 interface that connects the PC1 LAN to Router1.

It is the IP address of Switch1 that connects PC1 to other devices on the same LAN.

It is the IP address of the ISP network device located in the cloud.
