Which message does an IPv4 host use to reply when it receives a DHCPOFFER message from a DHCP server?

DHCPREQUEST

Refer to the exhibit. Consider the IP address configuration shown from PC1. What is a description of the default gateway address?

It is the IP address of the Router1 interface that connects the PC1 LAN to Router1.

Which two OSI model layers have the same functionality as two layers of the TCP/IP model? (Choose two.)

Network Transport

Refer to the exhibit. PC1 issues an ARP request because it needs to send a packet to PC3. In this scenario, what will happen next?

RT1 will send an ARP reply with its own Fa0/0 MAC address.

Fill in the blank. ARP______ is a technique that is used to send fake ARP messages to other hosts in the LAN. The aim is to associate IP addresses to the wrong MAC addresses.

Spoofing

A client application needs to terminate a TCP communication session with a server. Place the termination process steps in the order that they will occur. (Not all options are used.)

Step 1: client send FIN Step 2: server sends ACK Step 3: server sends FIN Step 4: client sends ACK
