Which of the following is an example of a networking device that connects two or more different networks?

• Hub

• Switch

• Router

• Repeater

Answer explanation

A router is a networking device that connects two or more different networks, directing data between them. In contrast, a hub, switch, and repeater operate within a single network segment.

The topology in which every device is connected to a single central hub is called:

• Ring topology

• Mesh topology

• Star topology

• Bus topology

Answer explanation

The star topology features a central hub to which all devices connect directly. This structure allows for easy management and troubleshooting, distinguishing it from ring and mesh topologies.

Which topology provides a dedicated point-to-point connection between every pair of devices?

• Bus topology

• Ring topology

• Mesh topology

• Star topology

Answer explanation

Mesh topology provides a dedicated point-to-point connection between every pair of devices, ensuring high reliability and redundancy. In contrast, bus, ring, and star topologies do not offer this level of direct connectivity.

What is the main function of an IP address?

• To identify a website name

• To uniquely identify a device in a network

• To provide encryption

• To convert analog signals

Answer explanation

The main function of an IP address is to uniquely identify a device in a network, allowing for proper communication between devices. Other options do not accurately describe the role of an IP address.

The IPv4 address is of how many bits?

• 32 bits

• 64 bits

• 128 bits

• 16 bits

Answer explanation

The IPv4 address consists of 32 bits, which are divided into four octets. Each octet contains 8 bits, making a total of 32 bits. This is why the correct answer is 32 bits.

Which layer of the OSI model is responsible for end-to-end delivery of messages?

• Transport layer

• Network layer

• Session layer

• Application layer

Answer explanation

The Transport layer is responsible for end-to-end delivery of messages, ensuring complete data transfer between hosts. It manages error recovery and flow control, making it essential for reliable communication.

Which device regenerates weak signals?

• Switch

• Repeater

• Bridge

• Router

Answer explanation

A repeater is a device specifically designed to regenerate and amplify weak signals, ensuring they can travel longer distances without degradation. This makes it the correct choice for the question.

A modem is used for:

• Converting digital signals to analog and vice versa

• Boosting weak signals

• Boosting weak signals

• Storing IP addresses

Answer explanation

A modem is primarily used for converting digital signals from a computer into analog signals for transmission over phone lines, and vice versa, enabling internet connectivity.

Which of the following has the highest data transfer rate

• Coaxial cable

• Optical fiber

• Twisted pair

• Microwave

Answer explanation

Optical fiber has the highest data transfer rate among the options due to its ability to transmit data as light signals, allowing for faster speeds and greater bandwidth compared to coaxial cable, twisted pair, and microwave.

Which protocol provides secure remote login?

• Telnet

• SSH

• FTP

• HTTP

Answer explanation

SSH (Secure Shell) provides a secure method for remote login, encrypting the data transmitted between the client and server. In contrast, Telnet is not secure, and FTP and HTTP do not focus on remote login.
