Question7Refer to the exhibit. Host A is configured with the correct IP address for the default

gateway of the router R1 FastEthernet0/1 interface. How will a packet that is sent fromhost A to host B be handled by the devices on the network?

R1 will forward the packet to its default gateway, the next hop router R2. R2 will forward the pa

connected network 10.1.1.0/24.
