Which of the answers listed below refers to a data-link layer device designed to forward frames between network segments?

Switch

A type of layer 2 network switch with configuration features that can be modified through a user interface is known as:

Managed switch

An infrastructure device designed for connecting wireless/wired client devices to a network is commonly referred to as:

Access Point (AP)

A simple device consisting of multiple connector blocks and ports used for cable management is known as:

Patch panel

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?

Firewall

A solution that allows to supply electricity over standard Ethernet cables is known as:

PoE; IEEE 802.3af

Which of the following answers refers to a dedicated device designed for supplying power over Ethernet cabling?

Injector

Which IEEE standard implements PoE+?

IEEE 802.3at

The IEEE 802.3bt standard implements:
