Which of the following scenarios best illustrates the application of a Peer-to-Peer network's core functionality?

• A large corporation managing user authentication and data backups through a centralized server.

• A small team of researchers collaboratively sharing files directly between their individual workstations without a dedicated server.

• An enterprise network leveraging a server farm for cloud computing services.

• A public Wi-Fi hotspot providing internet access to numerous devices via a central router.

A network administrator is tasked with designing a network for a new small business with limited IT support. The business anticipates rapid growth. Given the information on network types, which network architecture would be the least suitable choice for long-term scalability and why?

• Client/Server, because it centralizes services for easier management.

• Peer-to-Peer, because its efficiency decreases rapidly with an increasing number of computers.

• Local Area Network (LAN), as it covers a small geographic area.

• Wide Area Network (WAN), as it connects networks over great distances.

Consider a situation where a computer's performance significantly degrades while it is actively serving requests for files from other computers on a network. This observation is most indicative of a:

• Peer-to-Peer network, where the serving computer experiences reduced performance.

• Client/Server network, where the server is overloaded.

• Wide Area Network (WAN) with high latency.

• Star topology network with a failing central hub.

An organization requires a network that simplifies the administration of user accounts, security, and access control for a large number of users. Based on the provided information, which network model is best suited to meet these requirements?

• Peer-to-Peer network, due to individual user control over resources.

• Bus topology network, for its simplicity.

• Client/Server network, due to the centralization of user accounts and security.

• Ring topology network, for its ordered data flow.

A company is expanding its network and needs to connect two existing LAN segments, allowing computers on either segment to access resources on the other, while also being able to divide the large network into smaller segments for better management. Which networking device would be the most appropriate choice for this task?

• Hub.

• Repeater.

• Bridge.

• Router.

An engineer is designing a network that needs to efficiently forward data packets between different networks based on their logical addresses. Which networking component is essential for this functionality?

• Switch.

• Hub.

• Router.

• Bridge.

A technician observes that network signals are weakening over a long cable run, leading to intermittent connectivity. To resolve this issue and extend the network's operational distance, which device should the technician implement?

• Hub.

• Repeater.

• Switch.

• Bridge.

When selecting a Network Interface Card (NIC) for a new workstation, an engineer must consider several factors to ensure compatibility and optimal performance. Which of the following is NOT listed as a key consideration for NIC selection?

• Type of Network (e.g., Ethernet, Token Ring).

• Type of Media (e.g., Twisted Pair, Fiber-Optic Cable).

• Type of Computer Interface (e.g., PCI, USB).

• Operating System version installed on the computer.

A network diagram depicts multiple computers connected to a central device, where a packet arriving at one port is copied to all other ports. This configuration most accurately represents a network utilizing a:

• Switch.

• Bridge.

• Hub.

• Router.

A network administrator is troubleshooting a connectivity issue where a specific workstation cannot communicate with any other device on the local network. Upon inspection, it's discovered that the workstation's unique identifier, hardwired into its Network Interface Card, is missing. What is this crucial identifier commonly known as?

• IP Address.

• Logical Address.

• MAC Address.

• OSI Layer Address.
