Network Devices Quiz Flashcards
Which of the answers listed below refers to a datalink layer (layer 2) device designed to forward frames between network segments?
Switch
A network switch equipped with the routing capability is sometimes is referred to as a layer 3 switch.
True
A device designed to filter and transfer data packets between dissimilar types of computer networks is called:
Router
The disadvantage from using this device results from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports which has a negative impact on network performance.
Hub
An infrastructure device designed for connecting wireless/wired client devices to a network is commonly referred to as:
Access Point
Which of the following answers describe the features of a network bridge? (Select 3 answers)
Makes forwarding decisions in software
Typically capable of connecting fewer network segments than switch (fewer physical ports)
Older and less effective type of network device in comparison to network switch
What are the characteristic traits of a network switch? (Select all that apply)
Makes forwarding decisions in hardware (ASIC)
Typically capable of connecting more network segments than a bridge (more physical ports)
Sometimes referred to as a multiport bridge
Newer and more effective type of network device in comparison to network bridge.
Which network device enables centralized management of WAPs (Wireless Access Points)?
Wireless LAN controller
A network device designed for managing the optimal distribution of workloads across multiple computer resources is referred to as:
Load balancer
In computer networking, a computer system or application that acts as an intermediary between another computer and the Internet is commonly referred to as:
Proxy
Network connection implemented with the use of a cable modem take advantage of: (Select 3 answers)
Cabling that carries TV signals
Coaxial cabling
Shared bandwidth
Which of the answers listed below apply to DSL modems? (Select 3 answers)
Dedicated bandwidth
Twisted-pair copper cabling
Telephone lines
In computer networking, the term “Attenuation” refers to a loss in signal strength during transmission caused by increasing distance and obstacles encountered on the signal path. The problem of attenuating circuit on the network can be solved by adding a device that boosts the signal strength. This type of device is known as:
Repeater
Private Branch Exchange (PBX) is an internal telephone exchange or switching system implemented in a business or office. PBX allows for handling of internal communications without the use of Public Switched Telephone Network (PSTN) service, also known as Plain Old Telephone Service (POTS). A Voice over Internet Protocol (VoIP) PBX, which takes advantage of existing LAN cables, can further reduce costs by removing the need for separate telephone cabling infrastructure in a building or office. VoIP endpoints are specialized hardware devices for application programs that enable VoIP calls from computer devices. VoIP gateways are network devices that convert voice and fax calls, in real time, between an IP network an PSTN/POTS.
True
Media converters are devices that allow for connecting different types of incompatible media such as copper and fiber-optic cabling.
True
