Question 1

The data link layer takes the packets from _________ and encapsulates them into frames for transmission.
A)network layer
B)physical layer
C)transport layer
D)application layer

Accepted Answer

The data link layer takes packets from the network layer (Layer 3 in the OSI model) and encapsulates them into frames for transmission over the physical layer.

Question 2

CRC stands for
A)cyclic redundancy check
B)code repeat check
C)code redundancy check
D)cyclic repeat check

Accepted Answer

CRC stands for Cyclic Redundancy Check, which is a method used to detect errors in digital data.

Question 3

Which one of the following is the multiple access protocol for channel access control?
A)CSMA/CD
B)CSMA/CA
C)Both CSMA/CD & CSMA/CA
D)None of the mentioned

Accepted Answer

Both CSMA/CD (Carrier Sense Multiple Access with Collision Detection) and CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) are multiple access protocols used for channel access control in networks.

Question 4

Which one of the following is a transport layer protocol used in networking?
A)TCP
B)UDP
C)Both TCP and UDP
D)None of the mentioned

Accepted Answer

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both transport layer protocols used in the Internet protocol suite for transmitting data between devices across a network.

Question 5

Transport layer protocols deals with
A)application to application communication
B)process to process communication
C)node to node communication
D)none of the mentioned

Accepted Answer

Transport layer protocols are designed to facilitate process-to-process communication, ensuring that data is delivered from a specific process on one device to a specific process on another device.

Question 6

Which one of the following is a transport layer protocol?
A)stream control transmission protocol
B)internet control message protocol
C)neighbor discovery protocol
D)dynamic host configuration protocol

Accepted Answer

Stream Control Transmission Protocol (SCTP) is a transport layer protocol used for transmitting multiple streams of data simultaneously between two endpoints in a network, similar to TCP and UDP which are also transport layer protocols.

Question 7

When displaying a web page, the application layer uses the _____________
A)HTTP protocol
B)FTP protocol
C)SMTP protocol
D)TCP protocol

Accepted Answer

The application layer uses the HTTP protocol for displaying web pages. HTTP stands for Hypertext Transfer Protocol and is specifically designed for transferring web pages on the internet.

Question 8

Application layer protocol defines ____________
A)types of messages exchanged
B)message format, syntax and semantics
C)rules for when and how processes send and respond to messages
D)all of the mentioned

Accepted Answer

Application layer protocols define the types of messages exchanged, their format, syntax, semantics, and the rules for when and how processes send and respond to messages.
