ROUTING TABLE

What is the primary function of a routing table in computer networking?

• To store route information about directly connected and remote networks

• To act as a firewall for network security

• To provide internet access to all connected devices

• To manage user access to the network

Which of the following best describes a static route in a routing table?

• A route that is manually configured by a network administrator

• A route that is automatically learned through a dynamic routing protocol

• A route that changes based on network traffic

• A route that is used only for local networks

What is the role of the 'next hop' in a routing table?

• It indicates the next device along the path to the destination

• It provides the final destination address for the packet

• It determines the speed of data transmission

• It acts as a backup route in case of failure

How does a router use the routing table to forward a packet?

• By searching the routing information stored in the table

• By directly connecting to the destination node

• By encrypting the packet before sending

• By broadcasting the packet to all nodes

What happens if there is no route back to the source address in unicast reverse path forwarding (uRPF)?

• The packet is assumed to be malformed or involved in a network attack and is dropped

• The packet is sent back to the source for verification

• The packet is forwarded to the next available route

• The packet is stored in a temporary cache for analysis

the primary goal of routing protocols is the ... of routing tables.

what does a router need to forward a packet towards its destination network?

A routing table is analogous to a ​ (a)   map in ​ (b)   delivery. Whenever a ​ (c)    needs to send data to another node on a ​ (d)   , it must first know ​ (e)    to send it.

• When a router interface is configured with an IP address and subnet mask, the interface becomes

• static routes

• are routes that a network administrator manually configured.

• either dynamic or static.

• to remote networks that were learned automatically by the router through a dynamic routing protocol.
