Options- A. 16,382
- B. 8,190
- C. 4,094

- 4. Which of the following statement is incorrect?
Options- A. 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.
- B. 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.
