Module 9 Address Resolution Flashcards
What information is provided by ARP when an IP packet is sent to a host on a remote network?
ARP provides the MAC address of the router interface closest to the sending host.
What is the purpose of the ARP process in networking?
The purpose of the ARP (Address Resolution Protocol) process is to map an IP address to a MAC address, in order to determine the MAC address of a device on the same network.
What is the function of the ARP protocol?
The ARP protocol is responsible for resolving an IPv4 address to a MAC address.
What two types of addresses are mapped together in the ARP table in a switch?
The ARP table in a switch maps a Layer 3 address (IPv4 address) to a Layer 2 address (MAC address).
Which router component holds the routing table, ARP cache, and running configuration file?
The main memory or RAM (Random Access Memory) holds the routing table, ARP cache, and running configuration file on a router.
What type of information is contained in an ARP table?
IP address to MAC address mappings
What command should a cybersecurity analyst use to view the MAC address a host is using to reach the default gateway when suspecting a man-in-the-middle attack?
The cybersecurity analyst should use the “arp -a” command to view the MAC address a host is using to reach the default gateway.
Which destination address is used in an ARP request frame?
The destination MAC address in an ARP request frame is set to all ones or “FF-FF-FF-FF-FF-FF” to indicate that the frame is a broadcast and is intended to be received by all devices on the network.
