Chapter 1 Introduction to TCP/IP Networking
ST
1) In the TCP/IP model, which layer defines the interface between software running on the
computer and the network itself?
A) Transport
B) Internet
C) Application
UV
D) Data link
Answer: C
Explanation: A) The transport layer is incorrect because it deals with data delivery and flow
control.
B) The Internet layer is incorrect because it deals with addressing and routing.
IA
C) Application is correct because the application layer protocols provide services to the
application software. The application layer does not define the application itself but does define
how the application can access the network.
D) The data link layer is incorrect because it deals with how to access media.

_A
2) Which layer of the TCP/IP model defines the rules for data packet recovery?
A) Transport
B) Internet
C) Application
PP
D) Data link
Answer: A
Explanation: A) Transport is correct because the transport layer protocols deal with error
recovery of data. The transport layer also handles the mechanism to guarantee delivery across the
network. The other layers do not.

3) What are the two main services provided by the network layer of the TCP/IP model?
A) Compression
B) Addressing
VE
C) Routing
D) Reliability
E) Encryption
Answer: B, C
Explanation: B) Addressing and routing are correct answers because addressing deals with
D?
placing the correct IP address in the packet, and routing deals with getting the packet to the
correct destination.
C) Addressing and routing are correct answers because addressing deals with placing the correct
IP address in the packet, and routing deals with getting the packet to the correct destination.

, 4) The process of forwarding an IP packet from host to host is known as ________.
A) Delivery
B) Switching
ST
C) Routing
D) Sending
Answer: C
Explanation: C) Routing is the correct answer because routing deals with getting the packet to
the correct destination. Switching deals with getting frames to their correct destinations. Routing
UV
works much like the postal service to deliver messages to the correct destination.

5) What name is given to the process of enclosing data with headers and trailers as the data is
moved down the TCP/IP model?
IA
A) Condensing
B) Inclosing
C) Encryption
D) Encapsulation
Answer: D
_A
Explanation: D) Encapsulation is the correct answer because as the data moves down the
TCP/IP model and each layer attaches its control data, this process is known as encapsulation.

6) Which layer of the OSI model defines how to start, control, and end conversations by
PP
grouping messages in a workflow?
A) Application layer
B) Presentation layer
C) Session layer
D) Transport layer
RO
E) Network layer
F) Data link layer
G) Physical layer
Answer: C
Explanation: C) The session layer defines the start, control, and end of conversations (called
VE
session) with each computer.

, 7) Which layer of the OSI model defines functions related to data delivery, error recovery, and
flow control?
A) Application layer
ST
B) Presentation layer
C) Session layer
D) Transport layer
E) Network layer
F) Data link layer
UV
G) Physical layer
Answer: D
Explanation: D) The transport layer focuses on issues related to data delivery to another
computer (for example, error recovery and flow control).

8) Which layer of the OSI model provides an interface between the network and the software
running on a host machine?
A) Application layer
B) Presentation layer
_A
C) Session layer
D) Transport layer
E) Network layer
F) Data link layer
G) Physical layer
PP
Answer: A
Explanation: A) The application layer focuses on issues related to communication between the
software and the network.

9) In IT, what term refers to a small network that is used for business purposes, typically in the
home of a business or employee?
A) Organizational network
B) Enterprise network
C) IT network
VE
D) SOHO network
E) Cloud network
Answer: D
Explanation: D) When you start to work in a new industry, it is good to be familiar with some of
the most popularly used terms. When referring to a small network that is used for business
D?
purposes and is typically located in the home of the business (home office) or employee, the term
SOHO (Small Office, Home Office) is typically used.
