Consider the case where three devices are located within a LAN. Each device information is as follows: Device 1: IP - 192.168.0.2, MAC - 01:02:03:04:05:06Device 2: IP - 192.168.0.3, MAC - 01:03:05:07:09:0bDevice 3: IP - 192.168.0.4, MAC - aa:bb:aa:bb:aa:bbAssume the network is not compromised by any attackers. If device 1 broadcast an ARP request to query the MAC address of 192.168.0.4, which of the following should be considered a legitimate response of this ARP request? (select all that apply)Group of answer choicesaa:bb:aa:bb:aa:bb01:02:03:04:05:06cc:dd:cc:dd:cc:dd01:03:05:07:09:0b

What is the purpose of an ARP response? To let a broadcasting node know what is the MAC address to put into the destination hardware address fi To prevent a flood of UDP packets To improve authentication security To send an ACK message to the broadcasting computer

3What are two potential network problems that can result from ARP operation? (Choose two.)On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays.Multiple ARP replies result in the switch MAC address table containing entries that match the MAC addresses of hosts that are connected to the relevant switch port.Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network.Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing.

29What is the aim of an ARP spoofing attack?to overwhelm network hosts with ARP requeststo flood the network with ARP reply broadcaststo fill switch MAC address tables with bogus addressesto associate IP addresses to the wrong MAC address

Which protocol is used to find the MAC address of one node whose IP address is known?a.IPb.TCPc.ARPd.DNS

Three devices are on three different subnets. Match the network address and the broadcast address with each subnet where these devices are located. (Not all options are used.)Device 1: IP address 192.168.10.77/28 on subnet 1Device 2: IP address192.168.10.17/30 on subnet 2Device 3: IP address 192.168.10.35/29 on subnet 3Group of answer choicesSubnet 1 network numberSubnet 1 broadcast addressSubnet 2 network numberSubnet 2 broadcast addressSubnet 3 network numberSubnet 3 broadcast address
