Congratulations - you have completed CCNA - IP Networks.

You scored %%SCORE%% out of %%TOTAL%%.

Your performance has been rated as %%RATING%%

Your answers are highlighted below.

Question 1

You are using Wireshark to analyze packets on your network and you note that there is a field visible called sequence number. From this, what can you determine?

A	The packet is using UDP
B	The packet is destined for HTTP
C	The packet is using TCP
D	The packet is destined for FTP

Question 1 Explanation:

The presence of a sequence number would indicate TCP is in use as opposed to the connectionless UDP. There is not enough information here to indicate the destination of the traffic.

Question 2

You have a Cisco switch in its default configuration. The switch connects to four workstations and one other Cisco switch. How many collision domains are on this device?

A	0
B	1
C	4
D	5
E	6

Question 2 Explanation:

There is a collision domain for each port in use.

Question 3

You are performing a Wireshark packet capture and you notice the following address in use on your system – 224.0.1.1. What is this address type used for?

A	It is used to send traffic to a specific default gateway
B	It is used to send traffic to all hosts
C	It is used to send traffic to a specific receiver
D	It is used to send traffic to the “closest” recipient
E	It is used to send traffic to a group of receivers

Question 4

Which of the following are examples of physical layer devices in a network? (Choose 3)

A	Switch
B	NIC
C	Hub
D	Ethernet cable
E	Bridge
F	Router

Question 4 Explanation:

The switch and bridge are layer 2 devices while a router is a layer 3 device.

Question 5

Which of the following would be the preferred transport layer protocol for carrying Voice over IP (VoIP)?

A	LLQ
B	UDP
C	TCP
D	HTTPS

Question 5 Explanation:

VoIP uses the efficiency of the connectionless UDP.

Question 6

Which of the following is a private IPv4 address?

A	172.1.1.1
B	10.10.10.1
C	196.192.1.1
D	12.10.1.102

Question 6 Explanation:

The Class A range that was designated private is 10.X.X.X

Question 7

You have the IP address and mask of 192.168.1.102 255.255.255.224 on your host. What is the first usable IP address on your subnet?

A	192.168.1.95
B	192.168.1.94
C	192.168.1.97
D	192.168.1.65
E	192.168.1.64

Question 7 Explanation:

This is the .96 subnet. The first usable is .97 and the last usable is .126.

Congratulations - you have completed The OSI Model Challenge.

You scored %%SCORE%% out of %%TOTAL%%.

Your performance has been rated as %%RATING%%

Your answers are highlighted below.

Question 1

Where are routers classically associated in the OSI model?

A	Physical
B	Data Link
C	Transport
D	Network

Question 1 Explanation:

The router is a Layer 3 (Network) device in the classic definition.

Question 2

What layer of the OSI model features the use of the reliable TCP approach and the connectionless UDP approach?

A	Network
B	Presentation
C	Transport
D	Session

Question 2 Explanation:

The Transport layer features the use of TCP or UDP to provide reliable or unreliable transport.

Question 3

What layer of the OSI model exists above the Transport layer?

A	Session
B	Network
C	Data Link
D	Physical

Question 3 Explanation:

The layers are Physical, Data Link, Network, Transport, Session, Presentation, Application. These are listed from bottom to top.

Question 4

What are the port numbers used by HTTP and HTTPS at the Transport layer? (Choose 2)

A	80
B	23
C	22
D	443
E	69

Question 4 Explanation:

HTTP and HTTPS use 80 and 443 for TCP port numbers.

Question 5

The process of adding information to data at each layer of the OSI model is known as what?

A	Delineation
B	Repudiation
C	Integrity checking
D	Authentication
E	Encapsulation

Question 5 Explanation:

Each layer encapsulates data with control information.

Question 6

What are two popular reasons to use a reference model like OSI? (Choose 2)

A	It ensures reliable transport under normal network conditions
B	It permits equipment from different vendors to communicate (typically)
C	It ensures that a single protocol is relied upon
D	It dictates how physical media must be deployed
E	It aids in network troubleshooting

Question 6 Explanation:

The use of a model can help multiple vendors design equipment that has a chance of working with other vendor equipment. Also, the use of a model can aid in troubleshooting.

Question 7

What is the PDU called at the Datalink Layer of the OSI model?

A	Packet
B	Frame
C	Bit
D	Segment
