What Are Two Functions Of A Router? (Choose Two.)

What are the two functions of a router? (Choose two.)

• The data low maintenance is done by the router.
• The segmentation at the second layer is provided by the router.
• The router establishes a connection between multiple IP networks. The best path for the packets is determined by it.
• The routing table was established based on the ARPA request.

Answer: The router establishes the connection for multiple networks and finds the best route for the data packets and transfers them to the destination port.

Now that you know the answer but let’s take a look at the other function of the router because these are the reasons that the router has been built in the first place. We have discussed them in the following article so stick to the end of the article.

Router and its functions

The router is the hardware device that is for the connection with the network .it also finds the best path for the data packets so that the packet went straight to its destination address. The router is for access to the internet and connects the office with the help of the virtual private network. Router use different types of a protocol such as the Ethernet, ATM, DSL, etc., router along the IP protocol use the various other protocol as well.

Functions of the router 

The router’s functioning is split into two different paths first; is to build the map and second use the static and dynamic protocol for that particular router. The dynamic protocol allows the router to tell the different networking devices not only about the topology but the different changes in the network as well. While the static routing is adamant and does not allow any kind of changes or is rather able to adapt them. The task for building the map with the help of a routing table is done by these two protocols.

As the router has different interfaces through them it receives the data. The network address is analyzed by a router, the address of the packets after then it decides the interface to forward that particular packet. The routing table is helpful in the decision making

Some of the router functions are discussed in the following section:

• The broadcasting of LAN is managed by it.
• It acts as the default gateway.
• Protocol translation is done by the router if needed.
• Data transfer to another network.
• Determine and learn the loop-free paths.
• Show the best path so that the packets reach the destination address.
• The IP packets which are attached to the computer on a different network will be sent from one subnet to another with the help of a router.
• The router acts as a firewall: the firewall protects the network from intrusion and threats .it can block unwanted and unauthorized access or traffic. The firewall software is installed on the computer but the router is determined with firewall firmware and software.
• The router is responsible for segmentation it sent the data packet from the internal network to the internet,it also protects the data so that any kind of damage may not occur.
