These are the user uploaded subtitles that are being translated: 1 00:00:05,060 --> 00:00:10,340 In this video I'm going to discuss my experiences taking the new Cisco CCN exam. 2 00:00:10,340 --> 00:00:16,490 I took the exam on the day that it was released by Cisco and then published my thoughts to YouTube. 3 00:00:16,610 --> 00:00:22,330 But I'm going to add that video to this course so that you also have that information. 4 00:00:22,430 --> 00:00:24,300 I'll also give you some updates. 5 00:00:24,350 --> 00:00:29,090 One of the questions that I've often been asked is how many questions are there in the exam. 6 00:00:29,090 --> 00:00:35,260 And before we continue please note I have to be careful because of the Cisco NDA or non-disclosure agreement. 7 00:00:35,270 --> 00:00:39,950 I'd love to tell you a lot more information about the exam but I have to be really careful because of 8 00:00:39,950 --> 00:00:40,780 the NDA. 9 00:00:40,880 --> 00:00:41,810 I will say this. 10 00:00:41,810 --> 00:00:45,200 There are over 100 questions in the exam. 11 00:00:45,200 --> 00:00:50,240 In other words there are many more questions than the previous release of the CCMA exam. 12 00:00:50,240 --> 00:00:51,870 You have 120 minutes. 13 00:00:51,890 --> 00:00:55,180 In other words you get about a minute per question. 14 00:00:55,280 --> 00:00:58,800 You have to be really careful with your time management. 15 00:00:58,850 --> 00:01:03,420 There are some other surprises in the exam with regards to simulations. 16 00:01:03,560 --> 00:01:08,930 So I can't say too much but please note that there are differences compared to the previous version 17 00:01:08,930 --> 00:01:10,270 of the exam. 18 00:01:10,340 --> 00:01:13,640 I personally thought that the exam was easier. 19 00:01:13,640 --> 00:01:18,940 It covered a breadth of topics but wasn't as difficult as the previous releases of CCMA. 20 00:01:19,190 --> 00:01:24,330 Firstly because it doesn't cover as many topics and also because of the exam question types that in 21 00:01:24,370 --> 00:01:27,950 the exam but I have to be careful saying more than that. 22 00:01:27,950 --> 00:01:33,080 But let me tell you you still have to be well-prepared for the exam new topics such as wireless. 23 00:01:33,080 --> 00:01:38,810 There's a greater emphasis on security and network automation of new topics that you need to make sure 24 00:01:38,810 --> 00:01:41,010 that you understand and learn about. 25 00:01:41,030 --> 00:01:42,770 We'll be covering those topics in this course. 26 00:01:42,780 --> 00:01:44,500 So you'll have that information. 27 00:01:44,510 --> 00:01:48,620 I've also added the blueprint or list of topics to the course. 28 00:01:48,770 --> 00:01:49,800 So download that. 29 00:01:49,850 --> 00:01:54,230 I highly recommend that you go through that before you take your exam. 30 00:01:54,230 --> 00:01:58,580 This course will cover all the topics in the blueprint but it's well worth your time making sure that 31 00:01:58,580 --> 00:02:02,720 before you take the exam that you understand all the topics on the outline or blueprint. 32 00:02:03,020 --> 00:02:03,360 Okay. 33 00:02:03,390 --> 00:02:06,290 So I'm going to cut to this video. 34 00:02:06,290 --> 00:02:09,410 Hopefully it helps you. 35 00:02:10,030 --> 00:02:15,650 I'm David Bumble and I've just passed the new Cisco CCN exam 200 dash THREE OR 1. 36 00:02:15,750 --> 00:02:20,000 And in this video I'm going to give you some tips and tricks to help you in your preparation for the 37 00:02:20,000 --> 00:02:23,450 new Cisco CCN 200 dash 3 or 1 exam. 38 00:02:23,480 --> 00:02:27,370 Today I took both the Cisco CCMA as well as the Cisco definite exam. 39 00:02:27,650 --> 00:02:31,130 Fortunately I passed both of them so really happy about that. 40 00:02:31,190 --> 00:02:33,930 Some surprises however in this new exam. 41 00:02:34,070 --> 00:02:35,590 Some stuff that I thought was really good. 42 00:02:35,600 --> 00:02:39,410 Some stuff that I thought was strange some unexpected stuff. 43 00:02:39,410 --> 00:02:42,150 I'll talk about that in this video so keep watching. 44 00:02:42,200 --> 00:02:47,480 If you want to learn more about my experience taking the new Cisco CCMA exam 45 00:02:58,630 --> 00:02:59,830 now before we continue. 46 00:02:59,880 --> 00:03:05,040 If you enjoyed this video please

00:03:10,480 But also shared with others. 49 00:03:10,620 --> 00:03:14,550 Let other people know about my experience of the Cisco CCMA exam. 50 00:03:14,820 --> 00:03:19,710 Hopefully this will be of benefit to you and others hopefully you'll learn something. 51 00:03:20,040 --> 00:03:22,050 Okay so let's get started. 52 00:03:23,800 --> 00:03:25,450 Let me state this right in the beginning. 53 00:03:25,450 --> 00:03:28,590 I felt that the exam was very balanced. 54 00:03:28,630 --> 00:03:34,940 Covered a whole range of topics I think is a version one exam they call a CTA exam version one. 55 00:03:35,020 --> 00:03:36,130 I thought it was a good exam. 56 00:03:36,460 --> 00:03:38,750 However there were things that surprised me. 57 00:03:38,800 --> 00:03:45,550 Things that I didn't expect to see in the exam but on the whole I thought it was a good exam. 58 00:03:45,580 --> 00:03:47,140 I write a lot of quiz questions. 59 00:03:47,140 --> 00:03:53,020 I've written exam questions for vendors before it's very difficult to write good exam questions. 60 00:03:53,020 --> 00:03:57,880 It's much easier to answer any question than it is to write a question. 61 00:03:57,880 --> 00:04:02,210 It's much easier to criticize a question than it is to create a question. 62 00:04:02,230 --> 00:04:09,310 So I thought they did a great job a whole balance of various topics covered a wide range of topics in 63 00:04:09,310 --> 00:04:16,910 their list of of topics that you need to know but some hints would be concentrate on the new stuff spent 64 00:04:16,990 --> 00:04:18,490 time on the new stuff. 65 00:04:18,490 --> 00:04:22,870 Don't get bogged down in trying to memorize huge amounts of commands. 66 00:04:23,650 --> 00:04:27,850 So first step is learn the new stuff especially like wireless. 67 00:04:27,850 --> 00:04:28,960 Make sure you understand wireless. 68 00:04:28,970 --> 00:04:31,840 Make sure that you understand security topics. 69 00:04:31,840 --> 00:04:32,730 Now another tip. 70 00:04:32,980 --> 00:04:34,800 What do you need to prepare. 71 00:04:35,040 --> 00:04:38,970 Is packet Tracy enough and I would say definitely spend time using Packet Tracer. 72 00:04:38,980 --> 00:04:39,780 So do you need. 73 00:04:39,780 --> 00:04:42,670 Genius 3 Do you need viral. 74 00:04:42,670 --> 00:04:43,720 Do you need even. 75 00:04:43,810 --> 00:04:45,160 Do you need physical equipment. 76 00:04:45,160 --> 00:04:46,420 I like those products. 77 00:04:46,420 --> 00:04:47,820 I like the new viral. 78 00:04:47,950 --> 00:04:50,860 I'll be creating a video on the new viral very soon. 79 00:04:50,860 --> 00:04:52,650 I've already got access to viral 2.0. 80 00:04:52,660 --> 00:04:53,860 Great product. 81 00:04:54,130 --> 00:04:56,180 I love genius 3 love even. 82 00:04:56,500 --> 00:04:57,860 Those products are great. 83 00:04:57,880 --> 00:05:02,290 I really think you should use those products for CCNP positions. 84 00:05:02,320 --> 00:05:07,570 However I think packet traces enough if you can get access to physical equipment that always helps. 85 00:05:07,570 --> 00:05:13,930 If you can get access to genie 3 or viral that's great as well because it'll have options that you won't 86 00:05:13,930 --> 00:05:14,980 see and packet tracer. 87 00:05:15,740 --> 00:05:17,360 Okay so I think packet traces enough. 88 00:05:17,380 --> 00:05:22,850 I don't think you need to invest in buying hardware even though I think it's recommended. 89 00:05:22,900 --> 00:05:24,580 It's not a requirement. 90 00:05:24,580 --> 00:05:27,610 I don't think you have to buy viral. 91 00:05:27,610 --> 00:05:32,800 However again I would suggest that you do that as soon as you can because packet Trace is great but 92 00:05:32,800 --> 00:05:38,230 it's at this level and then viral genius 3 even G and physical equipment is at this level. 93 00:05:38,230 --> 00:05:42,910 So if you want to really increase your knowledge if you really wanna increase your understanding I'd 94 00:05:42,910 --> 00:05:48,670 recommend that you get those products but it's not required for the CCMA exam for my CS in a course 95 00:05:48,700 --> 00:05:52,680 I'm going to concentrate exclusively on Packet Tracer labs. 96 00:05:52,780 --> 00:05:57,720 So in the past I used to use junior 3 labs but a lot of people struggled with those labs. 97 00:05:57,760 --> 00:06:02,470 It's quite difficult to set up especially if you're new to Cisco so I'd recommend Packet Tracer. 98 00:06:02,710 --> 00:06:05,950 Easy to setup official product from Cisco. 99 00:06:05,950 --> 00:06:11,800 Brilliant simulation software allows you to simulate many many topics specifically for the CCMA. 100 00:06:11,850 --> 00:06:16,450 I would highly recommend Cisco packet tracer and that's what I'm going to base my course on. 101 00:06:16,810 --> 00:06:24,100 Now one of the best places to look if you preparing for a Cisco exam is the Cisco outline or Cisco details 102 00:06:24,190 --> 00:06:25,760 of the Exam. 103 00:06:25,780 --> 00:06:28,690 Exam is 120 minutes 200 dash 3 or 1. 104 00:06:28,690 --> 00:06:30,310 This kind of stuff you know ready. 105 00:06:30,700 --> 00:06:37,540 One of the first things I would do if I were you is have a look at the exam topics and I've downloaded 106 00:06:37,570 --> 00:06:41,360 the exam topics here and this is where it got interesting. 107 00:06:42,100 --> 00:06:46,400 Okay so let's start with one topic straight away EAI GOP. 108 00:06:46,480 --> 00:06:55,870 There is no easy GOP and no V.P. now when preparing for the exam I highly recommend Wendell Odom's official 109 00:06:55,870 --> 00:06:56,550 cert guides. 110 00:06:57,130 --> 00:07:02,730 I strongly suggest that you buy these guides and you use them lots of good information in here. 111 00:07:02,740 --> 00:07:08,440 I spent a bit of time going through these and I might have missed some stuff but even then I was quite 112 00:07:08,440 --> 00:07:09,820 surprised by a few things. 113 00:07:10,480 --> 00:07:19,170 Okay so in Wendell Odom's official cert guide he does mention EAI GOP in multiple places such as when 114 00:07:19,170 --> 00:07:24,590 you discuss metrics so I purchase both the physical books as well as the PDA. 115 00:07:24,610 --> 00:07:25,860 I like having both. 116 00:07:25,940 --> 00:07:31,980 So in this example I'm looking at the PDA version so that I can share it much more easily in this video. 117 00:07:31,990 --> 00:07:33,540 Notice he's got this table here. 118 00:07:33,540 --> 00:07:37,060 He talks about the different types of writing calculations. 119 00:07:37,140 --> 00:07:40,570 Your job he calculates based on bandwidth and delay. 120 00:07:40,660 --> 00:07:46,510 So even though my job he is not in the list of topics for the exam he actually covers it in the official 121 00:07:46,510 --> 00:07:47,780 said Guy. 122 00:07:47,830 --> 00:07:53,860 So on the left I'm doing searches for my GOP and what you'll notice is there's a whole bunch of entries 123 00:07:53,860 --> 00:07:58,030 for each GOP such as administrative distance. 124 00:07:58,140 --> 00:08:02,200 Now it's difficult to understand administrative distance if the only writing protocol you're going to 125 00:08:02,200 --> 00:08:04,220 talk about is oh SPF. 126 00:08:04,390 --> 00:08:08,560 Here we have a table of the administer of distances for various writing protocols. 127 00:08:08,560 --> 00:08:15,160 Notice we have both BGP and EAI GOP as well as ISIS. 128 00:08:15,610 --> 00:08:21,700 So don't just learn o SPF in isolation and just say I'm going to learn o SPF and ignore yay GOP ignore 129 00:08:21,700 --> 00:08:23,770 BGP ignore ISIS. 130 00:08:23,770 --> 00:08:26,530 Make sure that you understand administrative distances. 131 00:08:26,530 --> 00:08:32,980 Make sure that you understand that if ISIS advertises a right to you or SPF advertises the right to 132 00:08:32,980 --> 00:08:38,350 you and each GOP advertises the right to you and BGP advertises the right to you that you know which 133 00:08:38,350 --> 00:08:41,110 route is going to be selected and why now. 134 00:08:41,110 --> 00:08:45,970 I've previously created videos about this I've created quiz questions about this. 135 00:08:45,970 --> 00:08:47,350 Have a look at this video. 136 00:08:47,350 --> 00:08:56,170 An example where I explain why for instance o SPF is chosen b over EAI GOP or why rep is chosen over 137 00:08:56,480 --> 00:08:59,440 the GOP or over a SPF. 138 00:08:59,440 --> 00:09:03,790 When choosing the best route make sure that you know routes elections. 139 00:09:03,790 --> 00:09:09,020 You really need to understand the stuff for the CCMA exam so make sure that you know a D. 140 00:09:09,190 --> 00:09:11,220 Don't just say I don't need to learn. 141 00:09:11,310 --> 00:09:12,760 GOP. 142 00:09:12,980 --> 00:09:20,420 Make sure you understand it again while talking about the GOP I mentioned V.P. so doing a search for 143 00:09:20,420 --> 00:09:21,890 V.P.. 144 00:09:22,080 --> 00:09:26,540 There's a whole section here talking about veal and trucking protocol and he says before showing more 145 00:09:26,540 --> 00:09:33,260 configuration examples you need to know something about a Cisco protocol called V.P. and he discusses 146 00:09:33,260 --> 00:09:36,070 a whole bunch of stuff including V.P. mode. 147 00:09:36,080 --> 00:09:41,310 Transparent so it's not as if you can just ignore the DP. 148 00:09:41,330 --> 00:09:50,990 He discusses it in multiple places in his student guide and he says this book does not discuss V.P. 149 00:09:51,020 --> 00:09:53,960 as an end to itself for different reasons. 150 00:09:53,990 --> 00:09:56,370 He says it's not currently in the blueprint. 151 00:09:56,720 --> 00:10:00,170 And additionally many enterprises choose to disable VTB. 152 00:10:00,170 --> 00:10:02,830 However it still has an effect. 153 00:10:02,840 --> 00:10:10,310 My personal opinion is that I won't remove ETP from my new Cisco CCN course I'll reduce the amount of 154 00:10:10,310 --> 00:10:15,470 information about it and reduce sort of some of the troubleshooting scenarios stuff like that. 155 00:10:15,680 --> 00:10:21,610 But in my new course I will definitely cover VTB going back to the Cisco exam topics. 156 00:10:21,620 --> 00:10:24,590 Make sure that you know the new stuff. 157 00:10:24,590 --> 00:10:27,960 Make sure that you spend time learning the new things. 158 00:10:28,040 --> 00:10:35,000 As an example make sure you know about controllers make sure that you know about Cisco DNA center and 159 00:10:35,000 --> 00:10:40,040 wireless LAN controllers but also don't forget about traditional stuff like what's the difference between 160 00:10:40,040 --> 00:10:41,610 TTP and UDP. 161 00:10:41,630 --> 00:10:45,340 What's the difference between other protocols so like HP versus DNS. 162 00:10:45,350 --> 00:10:47,690 Do you actually understand how those protocols work. 163 00:10:47,690 --> 00:10:49,480 Do you know what they're about. 164 00:10:49,490 --> 00:10:52,730 I mean all this stuff is covered in the outline. 165 00:10:52,730 --> 00:10:55,820 So I found that the exam covered a broad range of topics. 166 00:10:55,820 --> 00:10:59,530 I was surprised by some of the topics that are still asked in the exam. 167 00:10:59,930 --> 00:11:06,830 But when it comes to addressing and I missing it right now is submitting make sure that you know your 168 00:11:06,830 --> 00:11:07,380 subnet. 169 00:11:07,940 --> 00:11:16,910 If I give you an IP address and I say here's an IP address 1 9 2 1 6 8 1 30 slash 28. 170 00:11:16,950 --> 00:11:22,670 Make sure that you know network first host Last Host and Broadcast address. 171 00:11:22,770 --> 00:11:25,720 Make sure that you know that information. 172 00:11:25,770 --> 00:11:33,960 Make sure that you know if you were given a writing table or a subheading diagram that you'd know where 173 00:11:33,960 --> 00:11:37,910 devices on the network use tables. 174 00:11:37,910 --> 00:11:43,850 I'm not a big fan of tables but I will be creating videos and publishing them on YouTube as well as 175 00:11:43,850 --> 00:11:47,990 my course worth submitting tables to help you do the stuff quickly. 176 00:11:47,990 --> 00:11:53,780 You've got to be able to look at a writing table you've got to be able to look at a network diagram 177 00:11:53,900 --> 00:12:01,140 you've got to be able to know where a host is so something is always important and it's still important. 178 00:12:01,140 --> 00:12:03,080 Big topics Wi-Fi. 179 00:12:03,300 --> 00:12:08,140 Make sure that you know Wi-Fi topics such as encryption. 180 00:12:08,300 --> 00:12:11,160 So what encryption protocols are used on wireless. 181 00:12:11,160 --> 00:12:16,260 Make sure that you understand the theory of wireless but make sure that you also understand how to configure 182 00:12:16,260 --> 00:12:18,600 stuff through the wireless LAN controller. 183 00:12:18,600 --> 00:12:22,860 Don't skip that section new section in the exam. 184 00:12:22,860 --> 00:12:27,870 Make sure that you spend time on wireless and topics such as virtualization as an example. 185 00:12:27,870 --> 00:12:32,580 I mean that's not pure writing in switching but we've got this convergence of technologies so you need 186 00:12:32,580 --> 00:12:35,010 to understand virtualization as well. 187 00:12:35,070 --> 00:12:38,650 Traditional topics such as quality of service are also important. 188 00:12:38,730 --> 00:12:40,160 My exam was very balanced. 189 00:12:40,170 --> 00:12:45,920 A lot of topics from a whole range of areas for example routing. 190 00:12:45,920 --> 00:12:47,280 Do you understand how writing works. 191 00:12:47,290 --> 00:12:52,700 Do you understand a floating static ride vs. a raft such as default right. 192 00:12:52,720 --> 00:12:56,790 Or or a raft that was added by a writing protocol. 193 00:12:56,790 --> 00:12:57,650 Do you understand. 194 00:12:57,690 --> 00:13:03,830 Oh SPF because SPF is the only main protocol in the CDC. 195 00:13:04,020 --> 00:13:07,390 Make sure that you understand who SPF really really well. 196 00:13:07,470 --> 00:13:13,390 Make sure that you understand elections neighbor adjacencies different types of links. 197 00:13:13,390 --> 00:13:15,660 So here they mentioned point to point. 198 00:13:15,660 --> 00:13:21,270 If you enable a wispy F on a Ethernet interface what kind of network will it be if you enable it on 199 00:13:21,270 --> 00:13:22,410 a point to point link. 200 00:13:22,410 --> 00:13:23,550 What kind of link will it be. 201 00:13:23,670 --> 00:13:27,630 And that's important because once again a lot of when technologies have been removed from the course. 202 00:13:27,700 --> 00:13:32,920 BP has been removed from the course but yeah we've got a point to point link in SPF. 203 00:13:33,390 --> 00:13:37,050 So how would they test you about a point to point link if you don't have some kind of point to point 204 00:13:37,050 --> 00:13:39,890 link so SPF network type could be point to point. 205 00:13:39,930 --> 00:13:43,710 Which means you need a point to point link so don't just throw out all the old technologies and say 206 00:13:43,740 --> 00:13:50,430 I will not touch anything that has a HDL C or point to point type of connection. 207 00:13:50,580 --> 00:13:54,130 I personally will keep a little bit of that in my course. 208 00:13:55,450 --> 00:13:58,190 But you know it's not as big as it was previously. 209 00:13:59,050 --> 00:14:01,440 Okay big section is security fundamentals. 210 00:14:01,510 --> 00:14:04,710 I would spend a lot of time on security fundamentals. 211 00:14:04,710 --> 00:14:06,450 It's 15 percent of the exam. 212 00:14:06,670 --> 00:14:10,070 Make sure that you understand VPN. 213 00:14:10,330 --> 00:14:17,050 Make sure that you understand wireless security protocols make sure that you know how to configure wireless 214 00:14:17,380 --> 00:14:22,070 LANs using WPA to using appreciate keys via the gooey. 215 00:14:22,210 --> 00:14:25,270 Make sure that you understand properly as an example. 216 00:14:25,270 --> 00:14:29,480 Do you know the difference between authentication authorization and accounting. 217 00:14:29,530 --> 00:14:32,190 So I would spend a lot of time on security fundamentals. 218 00:14:32,190 --> 00:14:36,770 Big part of the course now and then automation and program ability. 219 00:14:36,880 --> 00:14:41,160 This is where things are going so you would need to know like what is a northbound API. 220 00:14:41,170 --> 00:14:42,250 What's a southbound API. 221 00:14:42,250 --> 00:14:45,850 What protocols would be used on northbound southbound. 222 00:14:45,850 --> 00:14:49,410 My big advice would be make sure you understand what a controller is. 223 00:14:49,420 --> 00:14:54,190 I've discussed this stuff and I've created videos showing a bit of history if you're interested but 224 00:14:54,220 --> 00:14:57,750 I spoke about this stuff on this video many years ago. 225 00:14:57,760 --> 00:15:02,830 What's the difference between separation of control plane data plane. 226 00:15:02,830 --> 00:15:04,360 What is a management plane. 227 00:15:04,360 --> 00:15:06,910 So if you have a controller. 228 00:15:07,330 --> 00:15:13,630 Traditionally we have a device like a rider with the management plane the control plane and the forwarding 229 00:15:13,630 --> 00:15:19,440 plane or data plane within the device but with a controller we take the control plane out of the device 230 00:15:19,450 --> 00:15:21,420 we put it in a centralized controller. 231 00:15:21,420 --> 00:15:26,830 Now in the original open flow model the controller was the brain and the switches became dumb or the 232 00:15:26,830 --> 00:15:27,990 riders became dumb. 233 00:15:28,060 --> 00:15:32,730 That didn't work very well didn't scale so SPF kind of died a death that's in the past now. 234 00:15:33,520 --> 00:15:41,020 But the idea with a controller is we can have a controller that for instance controls some aspects of 235 00:15:41,020 --> 00:15:41,980 forwarding. 236 00:15:41,980 --> 00:15:49,990 So in Wendell's CCN a book he spends a lot of time on SD a lot of information on SDI. 237 00:15:50,620 --> 00:15:56,560 I don't know if it's necessary to note that detail but make sure that you understand what is an underlying 238 00:15:56,560 --> 00:15:56,980 network. 239 00:15:57,040 --> 00:16:01,270 Essentially physical devices rather than switches running traditional stuff. 240 00:16:01,330 --> 00:16:07,240 You can however get rid of spanning tree and run a layer 3 network has the Underlay. 241 00:16:07,240 --> 00:16:09,240 Then you run an overlay on top of it. 242 00:16:09,310 --> 00:16:14,020 Now it sounds all complicated but it's just traditional stuff that's got a new spin on it. 243 00:16:14,020 --> 00:16:17,440 I would say so in the old old days and we've done this for years. 244 00:16:17,620 --> 00:16:18,460 The internet. 245 00:16:18,460 --> 00:16:21,040 Think of the Internet as an underlay. 246 00:16:21,280 --> 00:16:25,200 It doesn't understand what's going across it necessarily. 247 00:16:25,210 --> 00:16:30,250 If we especially if we put it in a tunnel so let's go back even further in the old old days we had a 248 00:16:30,250 --> 00:16:35,040 traditional telephone network where the switches in the cloud were intelligent and the phones were dumb. 249 00:16:35,110 --> 00:16:40,120 Then the intelligence was put on the phones and the using Skype as an example. 250 00:16:40,120 --> 00:16:47,660 And the networking core became dumb and we just simply made calls across the Internet using Skype. 251 00:16:48,370 --> 00:16:51,090 So the traditional telephony network was intelligent. 252 00:16:51,090 --> 00:16:56,230 It was replaced with an IP call that was essentially dumb it didn't understand all the applications 253 00:16:56,230 --> 00:16:57,280 going across it. 254 00:16:57,280 --> 00:17:03,340 And then we made calls across the Internet using Skype with intelligence in the endpoints or in the 255 00:17:03,340 --> 00:17:09,410 controllers which could be as an analogy call manage express or whatever controller we're using to set 256 00:17:09,410 --> 00:17:12,070 up the calls using IP devices. 257 00:17:12,070 --> 00:17:16,690 Now here in SDK we've got an underlay think of that kind of like the Internet. 258 00:17:16,690 --> 00:17:23,320 So we've got just switches routers they are dumb to a point and then we put an overlay on top of it. 259 00:17:23,320 --> 00:17:26,580 So we build a whole network on top of it using Vieques land. 260 00:17:26,590 --> 00:17:31,120 Now it sounds complicated it's just tunnels but the intelligence is that can automatically be built 261 00:17:31,360 --> 00:17:38,050 to apply policy so we can have a policy and an SD server so we could have a policy on a controller and 262 00:17:38,050 --> 00:17:41,490 then apply the policy to the overlay not to the Underlay. 263 00:17:41,740 --> 00:17:48,370 So rather than trying to manually configure access lists on individual devices we apply the policy and 264 00:17:48,370 --> 00:17:51,760 this is the whole idea with intent based networking. 265 00:17:51,760 --> 00:17:57,810 We apply a policy on the controller and then that's going to configure the devices with us overlay network. 266 00:17:57,820 --> 00:18:04,330 So from me to you there might be a 20 switches or 20 writers on the Internet as an example but when 267 00:18:04,330 --> 00:18:07,880 we set up a IP SAC tunnel logically it's a hop from me to you. 268 00:18:07,900 --> 00:18:11,960 Same kind of idea here we've got a whole bunch of physical devices as the Underlay. 269 00:18:11,960 --> 00:18:14,440 We put an overlay on top of it. 270 00:18:14,860 --> 00:18:16,540 Make sure you understand those concepts. 271 00:18:16,690 --> 00:18:23,400 Make sure that you understand rest but arrest in the definite exam there's obviously a lot more about 272 00:18:23,400 --> 00:18:23,720 that. 273 00:18:23,790 --> 00:18:29,430 Make sure that you understand the differences between Puppet Chef and sensible so answerable as an example 274 00:18:29,430 --> 00:18:30,650 doesn't need an agent. 275 00:18:30,690 --> 00:18:33,130 It's an agent less implementation. 276 00:18:33,330 --> 00:18:38,760 So I've created a whole sensible course so I'll take some of that experience and knowledge and attitude 277 00:18:38,760 --> 00:18:44,820 my new CCN course make sure that you understand that with Ansel it's kind of like with python scripts 278 00:18:45,480 --> 00:18:49,590 I can just SS H to the devices and make configuration changes on them. 279 00:18:49,710 --> 00:18:54,750 But with puppet and chef now with puppet you can do some interesting things but the idea is you run 280 00:18:54,750 --> 00:19:04,440 an agent on the device and you don't use SS H to talk to the agent using HDP s using a web based protocol 281 00:19:04,440 --> 00:19:06,410 rather than traditional SSA. 282 00:19:06,780 --> 00:19:12,210 So the idea is as your control over your controlling device or your management device talks to the agent 283 00:19:12,210 --> 00:19:16,570 on the device that then configure the device but with sensible its agent less. 284 00:19:16,590 --> 00:19:22,020 We're not running an agent or special software on the Rogers and switches we are connecting directly 285 00:19:22,050 --> 00:19:23,900 to them from a server. 286 00:19:24,390 --> 00:19:28,850 Make sure you can also interpret Jason encoded data. 287 00:19:28,880 --> 00:19:33,630 I was quite surprised by that one but yeah make sure you spend a bit of time on automation and program 288 00:19:33,630 --> 00:19:37,770 ability but don't get stuck on this topic. 289 00:19:37,770 --> 00:19:39,090 It's a new topic in the exam. 290 00:19:39,090 --> 00:19:40,440 Don't get stuck on it. 291 00:19:40,440 --> 00:19:47,350 Notice security fundamentals has more information wars it is more important it's 15 percent IP services 292 00:19:47,350 --> 00:19:48,580 is 10 percent. 293 00:19:48,720 --> 00:19:55,860 Talking about traditional stuff like the HP DNS A.P. S&P MP so isn't it. 294 00:19:55,860 --> 00:19:58,120 He's been run for years. 295 00:19:58,170 --> 00:20:03,240 Do you understand which underlying protocols are used by these upper layer protocols. 296 00:20:03,330 --> 00:20:06,840 So which protocol does S&P use. 297 00:20:06,840 --> 00:20:12,020 Is it UDP is a TTP which protocol does SSA use TTP UDP. 298 00:20:12,060 --> 00:20:16,290 Make sure that you understand various protocols and the underlying protocols under them. 299 00:20:16,290 --> 00:20:18,380 So I mean I could list all of these topics. 300 00:20:18,420 --> 00:20:22,360 I mean my exam was very broad covered a whole bunch of topics. 301 00:20:22,510 --> 00:20:24,250 I think it was a very balanced exam. 302 00:20:24,280 --> 00:20:26,620 I think it was a good exam. 303 00:20:27,110 --> 00:20:28,670 Okay so hopefully you've learned something. 304 00:20:28,670 --> 00:20:34,360 If you have please consider subscribing to my YouTube channel once again please like this video and 305 00:20:34,370 --> 00:20:36,660 please click on the belt to get notifications. 306 00:20:36,680 --> 00:20:39,320 I'm David Bumble and I want to wish you all the very best. 31243
