1 00:00:07,500 --> 00:00:14,580 This is one of multiple CCMA Exam Simulation quiz questions. 2 00:00:14,730 --> 00:00:18,920 Can you answer the questions yourself in these quiz questions. 3 00:00:18,920 --> 00:00:27,420 I'm using Cisco Packet Tracer to help you practically test and verify your knowledge of Cisco CCN eight 4 00:00:27,420 --> 00:00:31,190 topics in these quiz questions. 5 00:00:31,190 --> 00:00:35,960 We are testing your knowledge of the life of a packet. 6 00:00:36,020 --> 00:00:40,220 Do you understand destination and source MAC addresses. 7 00:00:40,220 --> 00:00:43,460 Do you understand where those are used. 8 00:00:43,460 --> 00:00:51,640 Do you understand how traffic flows through a network and the various encapsulation is used in a network. 9 00:00:51,650 --> 00:00:54,260 In this scenario I have two pieces. 10 00:00:54,260 --> 00:01:01,570 P.S. One on the left and P.S. two on the right they are connected to 36 50 switches. 11 00:01:01,820 --> 00:01:05,150 These switches are configured as a layer two switches. 12 00:01:05,270 --> 00:01:10,830 There are also two Cisco ISIL routers connected via a serial link. 13 00:01:10,850 --> 00:01:18,020 The scenario is P.S. One pings P.C. too you need to answer the following questions based on the Echo 14 00:01:18,020 --> 00:01:22,250 request message center from P.S. 1 2 P.S. 2. 15 00:01:22,440 --> 00:01:30,210 So look after the echo request a message not other traffic types and answer these questions. 16 00:01:30,380 --> 00:01:35,610 What is the destination MAC address of the frame at point A in the network. 17 00:01:35,630 --> 00:01:40,550 In other words what is the destination MAC address of the Echo request message. 18 00:01:40,700 --> 00:01:47,290 After this point what is the actual destination MAC address. 19 00:01:47,330 --> 00:01:54,410 So in other words you need to determine what are the actual MAC addresses by looking at the frame and 20 00:01:54,410 --> 00:02:02,460 determining to which device that MAC address belongs now to help you with this task in Packet Tracer 21 00:02:02,480 --> 00:02:09,920 use of the simulation mode simulation mode in Packet Tracer allows you to simulate the flow of traffic 22 00:02:10,010 --> 00:02:20,450 through a network and view what happens once you open up simulation mode on P.S. 1 generate traffic 23 00:02:20,710 --> 00:02:28,170 so send a ping to the IP address of P.C. to which is 10 1 3 2 24 00:02:31,700 --> 00:02:40,570 and have a look at how the traffic flows as we can see here and our packet has been created and the 25 00:02:40,570 --> 00:02:48,560 piece he is opting for the MAC address of the router if you don't want to see other traffic times you 26 00:02:48,560 --> 00:02:57,740 can edit your filters to only look at OP and ICMP traffic within in Packet Tracer. 27 00:03:01,210 --> 00:03:06,820 So what I'll do is reset to that simulation and send the packet again 28 00:03:10,820 --> 00:03:18,610 so we can see the OP a request to the router and the reply and then we can see the ICMP message. 29 00:03:18,830 --> 00:03:29,020 And if you click on the message you'll be able to view the inbound PD you and outbound PD you and then 30 00:03:29,020 --> 00:03:42,370 answer the questions so by using simulation mode or by simply looking at the configurations of the devices 31 00:03:42,430 --> 00:03:51,610 in the topology you should be able to answer these questions so they are various questions asking about 32 00:03:51,670 --> 00:03:57,580 mac addresses and encapsulation is used at different stages in the life of the packet 33 00:04:00,930 --> 00:04:01,530 for both. 34 00:04:01,560 --> 00:04:08,290 Echo request and echo reply do you know how packets are encapsulated. 35 00:04:08,330 --> 00:04:13,670 Do you know when MAC addresses are used and when they are not used. 36 00:04:13,760 --> 00:04:19,430 Download the attached packet trace a file and see if you can answer these questions yourself. 37 00:04:19,430 --> 00:04:21,600 Otherwise watch the next video. 38 00:04:21,770 --> 00:04:25,100 We are show you the answers to these questions.
