From year come year, Cisco has actually updated many versions with difference questions. The latest version is variation 6.0 in 2018. What is your version? It depends on her instructor producing your class. We recommend you come go thought all version if you room not clear. While you take digital test with netacad.com, friend may gain random concerns from every version. Every version have 1 come 10 different questions or more. ~ you review all questions, You have to practice through our virtual test device by walk to "Online Test" connect below.

You are watching: What happens to the first ping in a situation where the router responds to the arp request?

Objectives

Part 1: research an ARP Request

Part 2: research a switch MAC address Table

Part 3: study the ARP procedure in far Communications

Background

This task is optimized for viewing PDUs. The devices are already configured. You will gather PDU details in simulation mode and also answer a series of questions about the data you collect.

Part 1: research an ARP Request

Step 1: generate ARP request by pinging 172.16.31.3 indigenous 172.16.31.2.Click 172.16.31.2 and open up the Command Prompt.Enter the arp -d command to clear the ARP table.Enter Simulation mode and enter the command ping 172.16.31.3. Two PDUs will certainly be generated. The ping command cannot complete the ICMP packet without discovering the MAC resolve of the destination. For this reason the computer system sends one ARP broadcast frame to uncover the MAC attend to of the destination.Click Capture/Forward once. The ARP PDU moves Switch1 when the ICMP PDU disappears, wait for the ARP reply. Open up the PDU and also record the destination MAC address. Is this address detailed in the table above? NoClick Capture/Forward to move the PDU come the next device. How many copies of the PDU walk Switch1 make? 3What is the IP attend to of the machine that welcomed the PDU? 172.16.31.3Open the PDU and examine class 2. What taken place to the source and location MAC addresses? source became destination, FFFF.FFFF.FFFF turned right into MAC deal with of 172.16.31.3Click Capture/Forward till the PDU return to 172.16.31.2. How many duplicates of the PDU walk the switch make throughout the ARP reply? 1Step 2: examine the ARP table.Note that the ICMP packet reappears. Open up the PDU and examine the MAC addresses. Perform the MAC addresses the the source and location align v their IP addresses? YesSwitch earlier to Realtime and also the ping completes.Click 172.16.31.2 and go into the arp –a command. Come what IP deal with does the MAC resolve entry correspond? 172.16.31.3In general, once does an end machine issue an ARP request? as soon as it walk not know the receiver’s MAC address.

Part 2: study a move MAC resolve Table

Step 1: Generate extr traffic to populate the switch MAC address table.From 172.16.31.2, go into the ping 172.16.31.4 command.Click 10.10.10.2 and open the Command Prompt.Enter the ping 10.10.10.3 command. How countless replies were sent and received? 4 sent, 4 received.Step 2: research the MAC address table top top the switches.Click Switch1and then the CLI tab. Enter the show mac-address-table command. Do the entries exchange mail to those in the table above? YesClick Switch0, climate the CLI tab. Go into the show mac-address-table command. Execute the entries correspond to those in the table above? YesWhy room two MAC addresses linked with one port? since both devices attach to one port through the accessibility Point.

Part 3: examine the ARP process in far Communications

Step 1: Generate traffic to develop ARP traffic.Click 172.16.31.2 and open the Command Prompt.Enter the ping 10.10.10.1 command.Type arp –a. What is the IP address of the new ARP table entry? 172.16.31.1Enter arp -d to clear the ARP table and also switch to Simulation mode.Repeat the ping to 10.10.10.1. How countless PDUs appear? 2Click Capture/Forward. Click the PDU that is currently at Switch1. What is the target destination IP destination resolve of the ARP request? 172.16.31.1The location IP resolve is no 10.10.10.1. Why? The gateway address of the router user interface is stored in the IPv4 construction of the hosts. If the receiving host is no on the same network, the source uses the ARP procedure to determine a MAC attend to for the router interface serving together the gateway.Step 2: research the ARP table ~ above Router1.Switch to Realtime mode. Click Router1 and climate the CLI tab.Enter privileged EXEC mode and then the show mac-address-table command. How countless MAC addresses are in the table? Why? Zero, This command method something completely different than the move command present mac address-table.Enter the show arp command. Is over there an entry for 172.16.31.2? YesWhat happens to the very first ping in a case where the router responds come the ARP request? It time out.
