3EF4:0A8A:04B3::74A9:0000::6EF3

Question 2. Which of the following statement is incorrect?

The Addresses Resolution Protocol, ARP, allows a host to find the physical address of a target host on the same physical network, given only the target IP address.

The sender's IP - to- physical address binding is included in every ARP broadcast; receivers update the IP-to-Physical address binding information in their cache before processing an ARP packet.

ARP is a low-level protocol that hides the underlying network physical addressing, permitting us to assign IP-addresses of our choice to every machine.

all of the above

signal to noise ratio divided by the ratio of energy per bit to noise per hertz
