What are functions of a layer 2 switch Mcq?

Layer 2 features include address learning, forwarding and filtering of the network, and loop avoidance.

What is the benefit of layer 2?

Some advantages of Layer 2 include lower costs, only requires switching, no routing gear is necessary and offers very low latency.

What is the main function of switch?

In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another.

What is layer 2 and Layer 3 networking?

Generally speaking, Layer 2 is a broadcast Media Access Control (MAC) MAC level network, while Layer 3 is a segmented routing over internet protocol (IP) network.

Why would a Layer 2 switch need an IP?

Explanation: Layer 2 switches can be configured with an IP address so that they can be remotely managed by an administrator. Layer 3 switches can use an IP address on routed ports.

Which of the following is an advantage of using 2 layer switching?

Using a technique called microsegmentation, LAN switches provide increased performance for individual users because the switch allocates dedicated bandwidth to each switch port for each network segment. …

What are the 3 functions of a switch?

Three basic functins of a switch are Learning, Forwarding and Preventing Layer 2 Loops.

What is the function of the switch in a circuit Brainly?

A switch connects or separates two pieces of metal. When the metal pieces are connected, the circuit is closed.

What is a function of Layer 2 of the OSI model?

The data link layer (Layer 2) of the OSI moves data across a linked physical network. A layer 2 device on a computing network will transmit data to a destination according to Media Access Control (MAC) addresses, also known as Ethernet addresses.

Can we assign IP address to Layer 2 switch?

Contrary to Router/Firewall configuration, Layer 2 Switch has ports configured as Layer 2 which can’t be given an IP address, instead SVI (Switched Virtual Interface) needs to be assigned an IP address.

Why does a switch need an IP address?

The main reason for some switches having an IP address is for ease of access, including when being accessed remotely. When a switch has an IP address, it is easy to remotely connect to it and manage the configuration as and when is needed. Telnet is the method used to connect to the switch and from there, manage it.

How does a Layer 2 switch forward data?

Layer 2 switching (or Data Link layer switching) is the process of using devices’ MAC addresses to decide where to forward frames. Switches and bridges are used for Layer 2 switching. They break up one large collision domain into multiple smaller ones. In a typical LAN, all hosts are connected to one central device.

What is a layer 2 Ethernet switch?

A layer 2 switch is a type of network switch or device that works on the data link layer (OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded. It uses hardware based switching techniques to connect and transmit data in a local area network (LAN).

What is a Level 2 switch?

A level 2 switch forwards information by MAC address of the network card. It keeps an onboard database of all the directly attached machines MAC addresses of their NIC cards .

What are functions of network switch?

The basic function that any switch is supposed to perform is to receive information from any source connected to it and dispatch that information to the appropriate destination only. This thing differentiates switches from hubs. Hub gets the information and forwards that to every other device in the network.
