Submit

17. Which network device uses MAC addresses to send data only to the intended destination device?

Explanation

A switch operates at the data link layer of the OSI model and uses MAC addresses to identify devices on a local network. Unlike a hub, which broadcasts data to all connected devices, a switch intelligently forwards data packets only to the specific device associated with the destination MAC address. This targeted approach enhances network efficiency and security, ensuring that data is sent directly to the intended recipient rather than being indiscriminately distributed to all devices on the network.

Submit

18. A hub operates at which layer of the OSI model?

Explanation

A hub operates at the Physical Layer of the OSI model because it is a networking device that transmits raw bitstreams over a network. It does not interpret or manage data packets; instead, it simply receives incoming signals and regenerates them for transmission to all connected devices. This layer is responsible for the physical connection between devices, including the electrical, optical, or radio signals used for communication. Therefore, the hub's primary function aligns with the characteristics of the Physical Layer.

Submit

19. A hybrid topology is a combination of ____ or more topologies.

Explanation

A hybrid topology integrates two or more different network topologies to leverage the strengths of each while mitigating their weaknesses. For instance, combining a star topology with a bus topology can enhance scalability and performance. This flexibility allows organizations to optimize their network design based on specific needs, such as cost, performance, and reliability, making hybrid topologies adaptable to various scenarios. By utilizing multiple topologies, networks can achieve improved efficiency and resilience.

Submit

20. Which topology is considered the most reliable due to multiple data paths between devices?

Explanation

Mesh topology is considered the most reliable because it provides multiple pathways for data to travel between devices. In a mesh network, each device is interconnected, allowing for redundancy. If one connection fails, data can be rerouted through alternative paths, minimizing the risk of network failure. This inherent resilience makes mesh topology ideal for critical applications where reliability is paramount. Additionally, it enhances performance by balancing the load across various routes, ensuring efficient communication even under heavy traffic.

Submit

21. Which network topology uses a central switch to connect all devices?

Explanation

Star topology utilizes a central switch or hub to connect all devices in the network. Each device is independently connected to the central point, allowing for efficient data transmission and easy management. If one connection fails, it does not affect the others, enhancing reliability. This structure simplifies troubleshooting and network expansion, making it a popular choice in modern networking environments.

Submit

22. In a bus topology, a failure in the main cable affects all connected devices.

Explanation

In a bus topology, all devices are connected to a single central cable, known as the bus. This means that if there is a failure or break in the main cable, it disrupts the communication for all devices connected to it. Consequently, no data can be transmitted across the network, leading to a complete network failure. This characteristic makes bus topology less reliable compared to other topologies, as the entire network's functionality hinges on the integrity of the main cable.

Submit

23. Which network allows an organization to share its private network with external users such as suppliers or customers?

Explanation

An extranet is a private network that extends specific access to external users, such as suppliers or customers, while maintaining security and privacy. It allows organizations to share information and collaborate with external parties without exposing their entire internal network. This setup facilitates communication and resource sharing, enhancing operational efficiency and strengthening business relationships. In contrast, an intranet is limited to internal users, while the internet is a public network, and a LAN refers to a local area network that typically does not provide external access.

Submit

24. An intranet is best described as ____.

Explanation

An intranet is a private network that is exclusively used within an organization, allowing employees to communicate, share information, and collaborate securely. Unlike the internet, which is accessible to the public, an intranet provides a controlled environment where sensitive data can be managed and accessed only by authorized personnel. This enhances internal communication, streamlines processes, and fosters a sense of community among employees while maintaining privacy and security.

Submit

25. The Internet is an example of which type of network?

Explanation

The Internet is classified as a Wide Area Network (WAN) because it spans large geographical areas, connecting multiple smaller networks, such as Local Area Networks (LANs) and Metropolitan Area Networks (MANs). Unlike LANs that serve a limited area like a home or office, WANs can cover cities, countries, and even continents, facilitating global communication and data exchange. This extensive reach and capability to connect diverse networks make the Internet a prime example of a WAN.

Submit

26. Which network type covers an entire city?

Explanation

A Metropolitan Area Network (MAN) is designed to cover a larger geographic area than a Local Area Network (LAN), typically spanning an entire city. It connects multiple LANs within that area, facilitating high-speed data transmission and communication among various local networks. This makes MAN ideal for organizations or services that require extensive coverage within urban environments, providing efficient connectivity for businesses and institutions across the city.

Submit

27. What is the typical range of a Personal Area Network (PAN)?

Explanation

A Personal Area Network (PAN) is designed for short-range communication between personal devices, typically within a small area. The typical range of a PAN is 1–10 meters, which allows devices such as smartphones, tablets, and laptops to connect wirelessly without interference from other networks. This limited range is ideal for personal use, ensuring security and reducing the risk of unauthorized access while maintaining a reliable connection for data transfer and device control.

Submit

28. Which type of network is most suitable for small offices or home use with no dedicated server?

Explanation

A Peer-to-Peer (P2P) network is ideal for small offices or home use because it allows devices to connect directly to each other without a dedicated server. This setup is cost-effective, easy to configure, and provides adequate sharing of resources like files and printers among users. Each device can act as both a client and a server, making it flexible for small-scale operations where centralized management is unnecessary. This decentralized approach suits environments with fewer users and less complex networking needs.

Submit

29. In a client-server network, which device provides services to other devices?

Explanation

In a client-server network, the server is a centralized device that provides resources, services, and data to other devices known as clients. While clients request and consume these services, the server manages and responds to these requests, ensuring efficient communication and resource allocation. This architecture allows for better organization and control of network resources, making the server a crucial component in facilitating interactions and services across the network.

Submit

30. Which of the following is a goal of computer networking?

Explanation

One of the primary goals of computer networking is to enable resource sharing among multiple devices.
