Network switches are hardware components that centralize communications among multiple devices within a local area network. In most of the business networks, switches are used to connect computers, printers, and servers within a building.The right answer is B.

Transmission media is classified into two groups: guided media and unguided media. Guided media is the type of transmission media that is physically tangible in which the signals propagate over a solid substance such as a copper wire. Unguided media is the type of transmission media that sends the data through the air. The right answer is D.

Unshielded Twisted Pairs (UTP) are the ordinary copper wires and they are the most common transmission media in computer networking. The right answer is A.

A local area network (LAN) interconnects communication devices within a small geographical area such as an office, home or a building. The right answer is E.

In a mesh topology, each device has a point-to-point connection with a single or multiple devices.Since there exist redundant links in the network, the cabling cost is high in this topology.The right answer is C.

A spoofing attack occurs when the attacker impersonates another user or device on the network to attack the network, spread malware, and access data sources. The right answer is C.

Denial-of-Service attacks aim to prevent normal functioning of a computer system. DoS attacks usually flood the network with traffic until a shutdown occurs due to the overload. The right answer is A.

The requirements of network management are described with FCAPS, a model for network management created by ISO. FCAPS is the acronym for fault, configuration, accounting, performance, and security.

Accounting management aims to track the usage of computation and network resources to provide a fair distribution of resources among users. The right answer is C.

Transport Layer delivers data across network connections. It provides message segmentation, message acknowledgment, session multiplexing, and message traffic control. The right answer is D.
