Address Resolution Protocol Question & Answers September 6, 2022 By WatElectronics This article lists 75 Address Resolution Protocol || ARP MCQs for engineering students. All the Address Resolution Protocol || ARP Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Address Resolution Protocol || ARP. A logic address is used to send or receive messages in most cases of computers or applications. However, the communication relies upon Physical address i.e., the MAC Address present at the second layer of the OSI reference model. To make the devices communicate, our intention is to get the MAC destination address. For this purpose, ARP was introduced. This protocol is responsible for translating IP into Physical Addresses. ARP is considered one of the most prominent protocols in the Network layer of the OSI reference model. The connection of IP to MAC address provided by ARP needs to map the addresses because of the distinct lengths of addresses. Dynamic mapping is possible by ARP. MAC address is the Data Link Layer that terminates and establishes connections among the physical devices to transfer the data. An IP address is the Network layer that forwards the packets to various routers, and the ARP present works among these layers. In IP version 6 network Neighbour Discovery protocol provides ARP functioning. It is referred to as the Request-Response protocol. 1). What connects IP address to the Physical address of devices?
