Most common communication protocol on the internet that ensures end-to-end communication is called what?
- A.
TCP/IP
- B.
FTP
- C.
HTTP
- D.
SLIP/ppp
Correct Answer
A. TCP/IPExplanation
TCP/IP is the most common communication protocol on the internet that ensures end-to-end communication. TCP (Transmission Control Protocol) is responsible for breaking data into packets and reassembling them at the destination, while IP (Internet Protocol) is responsible for addressing and routing these packets across the network. Together, TCP/IP provides a reliable and efficient method for data transmission over the internet, making it the standard protocol for internet communication. FTP (File Transfer Protocol), HTTP (Hypertext Transfer Protocol), and SLIP/ppp (Serial Line Internet Protocol/Point-to-Point Protocol) are also used for specific purposes, but they do not provide the same level of end-to-end communication as TCP/IP.Rate this question:

What type of address is the following? 20:B9:F1:63:2F:FB
- A.
IP Address
- B.
MAC address
- C.
TCP/IP
- D.
HTTP
Correct Answer
B. MAC addressExplanation
The given address "20:B9:F1:63:2F:FB" is a MAC address. MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. It is used to uniquely identify devices on a local network. IP address is used to identify devices on a network at the internet layer, TCP/IP is a protocol suite used for internet communication, and HTTP is a protocol used for transferring hypertext over the internet.Rate this question:

Joy wants to upload and download files from/to a remote Internet server. Write the name of relevant communication protocols, which will let him do the same?
- A.
FTP
- B.
TCP/IP
- C.
HTTP
- D.
FTP,HTTP
Correct Answer
D. FTP,HTTPExplanation
The relevant communication protocols that will allow Joy to upload and download files from/to a remote Internet server are FTP and HTTP. FTP (File Transfer Protocol) is specifically designed for transferring files between a client and a server on a computer network. HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting hypertext over the internet, which includes the ability to download files. By using both FTP and HTTP, Joy will have the necessary protocols to perform file transfers in both directions.Rate this question:

The management wants that the network traffic should be minimized for this, which network device would you suggest?
Correct Answer
RouterExplanation
A router is the most suitable network device to minimize network traffic. Routers are designed to efficiently direct network traffic between different networks, such as local area networks (LANs) and wide area networks (WANs). They use routing tables to determine the best path for data packets to reach their destination, which helps to optimize network traffic flow. Additionally, routers can also implement network segmentation by creating separate subnets, which can further reduce unnecessary network traffic by limiting broadcasts and isolating network segments.Rate this question:
