Common Networking Hardware Flashcards
A device designed to filter and transfer data packets between dissimilar types of computer networks is called:
Hub
Load balancer
Router
Switch
Router
A device that forwards data packets to the appropriate parts of a computer network.
Which of the answers listed below refers to a data-link layer device designed to forward frames between network segments?
Hub
Switch
Firewall
Router
Switch
A network switch connects devices in a network to each other, enabling them to talk by exchanging data packets.
A type of layer 2 network switch with configuration features that can be modified through a user interface is known as:
Virtual switch
Multilayer switch
PoE switch
Managed switch
Managed Switch
Managed switches let users adjust each port on the switch to any setting, enabling them to manage, configure and monitor the network in many ways.
An infrastructure device designed for connecting wireless/wired client devices to a network is commonly referred to as:
Captive portal
Access Point (AP)
Intermediate Distribution Frame (IDF)
Active hub
Access Point (AP)
An access point is a device that creates a wireless local area network, or WLAN, usually in an office or large building. An access point connects to a wired router, switch, or hub via an Ethernet cable, and projects a WiFi signal to a designated area.
A simple device consisting of multiple connector blocks and ports used for cable management is known as:
Media converter
Demarc
Main Distribution Frame (MDF)
Patch panel
Patch Panel
A patch panel provides a way to keep large numbers of cables organized, enabling flexible connectivity into network hardware located in a data center or an access or wiring closet.
Which of the following answers refers to a software or hardware that monitors network traffic and depending on the configuration settings applied to each data packet either blocks it or allows it to pass through?
HIDS
Firewall
Packet filter
Vulnerability scanner
Firewall
A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization’s previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet

Which of the following answers refers to a dedicated device designed for supplying power over Ethernet cabling?
Inverter
Tap
Media converter
Injector
Injector
PoE injector connects your PoE-enabled network device to a non-PoE LAN switch port. More specifically, a PoE injector can be used to connect a wireless access point, IP phone, network camera or any IEEE 802.3af/at-powered device (PD) to a network switch.
Which IEEE standard implements PoE+?
IEEE 802.1d
IEEE 802.3at
IEEE 802.1X

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.
Router
Switch
Bridge
Hub
Hub
A hub is a physical layer networking device which is used to connect multiple devices in a network. They are generally used to connect computers in a LAN. A hub has many ports in it. A computer which intends to be connected to the network is plugged in to one of these ports.
A network segment utilizing only this type of device is the most prone to network performance degradation due to large number of network collisions.

Which type of fiber-optic equipment can be found at the demarc?
MDI
IDF
ONT
MDF
ONT
An ONT is an Optical Network Terminal and is also commonly referred to as a “fibre box”. The ONT is what allows the fibre optic cable to be connected from inside your home, out through your property and to the fibre network at the street.
demarcation point is the physical point at which the public network of a telecommunications company ends and the private network of a customer begins.
