Question 1

_______ is a protocol for e?mail services.&#10;A) FTP&#10;B) SMTP&#10;C) TELNET&#10;D) HTTP

Accepted Answer

SMTP (Simple Mail Transfer Protocol) is the standard protocol used for sending email messages over the internet. It is used by mail servers to exchange email messages with one another. FTP (File Transfer Protocol) is used for transferring files, TELNET is used for remote command-line access, and HTTP is used for website access. None of these protocols are specifically designed for email services like SMTP is.

Question 2

The _______ layer of the TCP/IP protocol suite provides services for end users.&#10;A) data-link&#10;B) transport&#10;C) application&#10;D) physical

Accepted Answer

The application layer provides services for end users, such as email, file transfer, and remote login. The data-link layer deals with the physical transmission of data, while the transport layer provides end-to-end communication between hosts. The physical layer deals with the actual physical transmission of data over a network.

Question 3

The _______ layer of the TCP/IP protocol suite transmits a bit stream over a physical medium.&#10;A) physical&#10;B) data-link&#10;C) network&#10;D) transport

Accepted Answer

The physical layer is responsible for transmitting a bit stream over a physical medium, such as a cable or wireless signal. The data-link layer is responsible for establishing and managing logical links between devices on the same network, while the network layer is responsible for routing data between different networks. The transport layer is responsible for ensuring reliable data transmission between endpoints.

Question 4

The _______ layer of the TCP/IP protocol suite is responsible for source-to-destination delivery of the entire message.&#10;A) transport&#10;B) network&#10;C) data-link&#10;D) session

Accepted Answer

The network layer is responsible for source-to-destination delivery of the entire message, ensuring that the data packets are routed across the network from the sender to the receiver.

Question 5

The _______ layer of the TCP/IP protocol suite is responsible for node-to-node delivery of a frame between two adjacent nodes.&#10;A) transport&#10;B) network&#10;C) data-link&#10;D) session

Accepted Answer

The data-link layer is responsible for node-to-node delivery of a frame between two adjacent nodes. The transport layer is responsible for end-to-end delivery and the session layer is responsible for managing sessions between applications. The network layer deals with routing and addressing.

Question 6

_______ protocol (s) is one of the protocols in the transport layer.&#10;A) Only TCP&#10;B) Only UDP&#10;C) Only SCTP&#10;D) TCP, UDP, and SCTP

Accepted Answer

TCP, UDP, and SCTP are all protocols in the transport layer.

Question 7

IP addresses are currently _______ bits in length.&#10;A) 4&#10;B) 8&#10;C) 32&#10;D) 40

Accepted Answer

IP addresses are currently 32 bits in length, which allows for approximately 4.3 billion unique addresses.

Question 8

Which physical topology uses a hub or switch?&#10;A) bus&#10;B) ring&#10;C) star&#10;D) bus and ring

Accepted Answer

A hub or switch is used in a star topology where all devices are connected to a central point. This is the best choice for reducing network collisions and increasing network reliability.

Question 9

The TCP/IP model has _______ layers.&#10;A) five&#10;B) six&#10;C) seven&#10;D) eight

Accepted Answer

The TCP/IP model has five layers: the physical layer, the data link layer, the network layer, the transport layer, and the application layer.

Question 10

_______ is a protocol for accessing and transferring documents on the WWW.&#10;A) FTP&#10;B) SMTP&#10;C) TELNET&#10;D) HTTP

Accepted Answer

HTTP (Hypertext Transfer Protocol) is the protocol used for accessing and transferring documents on the World Wide Web. FTP (File Transfer Protocol) is used for transferring files between servers and clients, SMTP (Simple Mail Transfer Protocol) is used for sending and receiving email, and TELNET is a protocol that provides interactive text-based communication between two computers.

Question 11

What is the domain name in the e?mail address kayla@nasa.gov?&#10;A) kayla&#10;B) kayla@nasa.gov&#10;C) nasa.gov&#10;D) gov

Accepted Answer

The answer of What is the domain name in the...
