PreviousA sender transmits frame 5 but does not receive its acknowledgement within the timeout interval. Assume the frame or its acknowledgement has been lost. What should the sender do? - (i) Retransmit frame 5 - (ii) Move directly to frame 6 - (iii) Discard all previously transmitted frames - (iv) Restart the entire connectionNextHost A knows the IP address of Host B, and both hosts are on the same LAN. Host A does not have Host B's MAC address in its ARP cache. What happens first? - (i) Host A broadcasts an ARP request asking for the MAC address corresponding to Host B's IP address - (ii) Host A unicasts the IP packet directly to Host B - (iii) Host B broadcasts its MAC address - (iv) The router assigns a new IP address to Host A
