1 00:00:05,050 --> 00:00:11,240 Now before I go any further if you're not planning on taking the new Cisco CCMA exam then skip this 2 00:00:11,240 --> 00:00:11,740 video. 3 00:00:11,870 --> 00:00:15,140 If you're only taking this course for information. 4 00:00:15,140 --> 00:00:19,900 In other words you're trying to learn networking but you're not interested in taking the CCMA exam. 5 00:00:19,970 --> 00:00:21,380 Then skip this video. 6 00:00:21,380 --> 00:00:25,630 Otherwise continue watching and I'm not going to discuss the new Cisco CCMA exam. 7 00:00:28,250 --> 00:00:33,360 In this video I'm going to discuss my experiences taking the new Cisco CCMA exam. 8 00:00:33,500 --> 00:00:39,660 I took the exam on the day that it was released by Cisco and then published my thoughts to YouTube. 9 00:00:39,770 --> 00:00:45,490 But I'm going to add that video to the scores so that you also have that information. 10 00:00:45,590 --> 00:00:47,470 I'll also give you some updates. 11 00:00:47,510 --> 00:00:52,250 One of the questions that I've often been asked is how many questions are there in the exam. 12 00:00:52,250 --> 00:00:58,460 And before we continue please note I have to be careful because of the Cisco NDA or non-disclosure agreement. 13 00:00:58,460 --> 00:01:03,110 I'd love to tell you a lot more information about the exam but I have to be really careful because of 14 00:01:03,110 --> 00:01:04,040 the NDA. 15 00:01:04,040 --> 00:01:04,920 I will say this. 16 00:01:04,970 --> 00:01:08,290 There are over 100 questions in the exam. 17 00:01:08,360 --> 00:01:13,370 In other words there are many more questions than the previous release of the CCMA exam. 18 00:01:13,400 --> 00:01:15,080 You have 120 minutes. 19 00:01:15,080 --> 00:01:18,340 In other words you get about a minute per question. 20 00:01:18,470 --> 00:01:21,950 You have to be really careful with your time management. 21 00:01:22,010 --> 00:01:26,630 There are some other surprises in the exam with regards to simulations. 22 00:01:26,720 --> 00:01:27,950 So I can't say too much. 23 00:01:27,950 --> 00:01:33,430 But please note that there are differences compared to the previous version of the exam. 24 00:01:33,500 --> 00:01:36,730 I personally thought that the exam was easier. 25 00:01:36,800 --> 00:01:42,090 It covered a breadth of topics but wasn't as difficult as the previous releases of CCMA. 26 00:01:42,380 --> 00:01:47,410 Firstly because it doesn't cover as many topics and also because of the exam question types that were 27 00:01:47,420 --> 00:01:48,260 in the exam. 28 00:01:48,610 --> 00:01:50,660 But I have to be careful saying more than that. 29 00:01:51,110 --> 00:01:56,160 But let me tell you you still have to be well-prepared for the exam new topics such as wireless. 30 00:01:56,280 --> 00:02:01,970 There's a greater emphasis on security and network automation of new topics that you need to make sure 31 00:02:01,970 --> 00:02:04,190 that you understand and learn about. 32 00:02:04,190 --> 00:02:05,960 We'll be covering those topics in this course. 33 00:02:05,960 --> 00:02:07,700 So you'll have that information. 34 00:02:07,700 --> 00:02:11,830 I've also added the blueprint or list of topics to the course. 35 00:02:11,960 --> 00:02:17,380 So download that I highly recommend that you go through that before you take your exam. 36 00:02:17,390 --> 00:02:21,770 This course will cover all the topics in the blueprint but it's well worth your time making sure that 37 00:02:21,770 --> 00:02:26,210 before you take the exam that you understand all the topics on the outline or blueprint. 38 00:02:26,240 --> 00:02:26,530 OK. 39 00:02:26,560 --> 00:02:36,240 So I mean a cut to the video hopefully it helps you I'm David Bumble and I've just passed the new Cisco 40 00:02:36,240 --> 00:02:38,850 CCMA exam 200 dash 3 or 1. 41 00:02:38,950 --> 00:02:43,170 And in this video I'm going to give you some tips and tricks to help you in your preparation for the 42 00:02:43,170 --> 00:02:46,610 new Cisco since you need 200 dash three or one exam. 43 00:02:46,620 --> 00:02:50,770 Today I took both the Cisco CCMA as well as the Cisco definite exam. 44 00:02:50,790 --> 00:02:54,320 Fortunately I passed both of them so really happy about that. 45 00:02:54,360 --> 00:02:58,760 Some surprises however in this new exam some stuff that I thought was really good. 46 00:02:58,770 --> 00:03:02,560 Some stuff that I thought was strange some unexpected stuff. 47 00:03:02,580 --> 00:03:05,300 I'll talk about that in this video so keep watching. 48 00:03:05,370 --> 00:03:10,650 If you want to learn more about my experience taking the new Cisco CCMA exam 49 00:03:21,790 --> 00:03:22,950 now before we continue. 50 00:03:23,040 --> 00:03:28,200 If

00:03:43,200 Hopefully this will be of benefit to you and others hopefully you'll learn something. 55 00:03:43,200 --> 00:03:46,870 Okay so let's get started. 56 00:03:46,980 --> 00:03:48,530 Let me state this right in the beginning. 57 00:03:48,630 --> 00:03:55,200 I felt that the exam was very balanced and covered a whole range of topics I think is a version one 58 00:03:55,200 --> 00:03:57,840 exam they call a CCMA exam version one. 59 00:03:58,170 --> 00:03:59,570 I thought it was a good exam. 60 00:03:59,610 --> 00:04:01,930 However there were things that surprised me. 61 00:04:01,980 --> 00:04:08,710 Things that I didn't expect to see in the exam but on the whole I thought it was a good exam. 62 00:04:08,730 --> 00:04:14,850 I write a lot of quiz questions I've written exam questions for vendors before it's very difficult to 63 00:04:14,850 --> 00:04:16,200 write good exam questions. 64 00:04:16,200 --> 00:04:21,060 It's much easier to answer any question than it is to write a question. 65 00:04:21,060 --> 00:04:25,380 It's much easier to criticize a question than it is to create a question. 66 00:04:25,410 --> 00:04:32,460 So I thought they did a great job a whole balance of various topics covered a wide range of topics in 67 00:04:32,460 --> 00:04:40,140 their list of of topics that you need to know but some hints would be concentrate on the new stuff spent 68 00:04:40,170 --> 00:04:41,420 time on the new stuff. 69 00:04:41,640 --> 00:04:46,650 Don't get bogged down in trying to memorize huge amounts of commands. 70 00:04:46,830 --> 00:04:51,030 So first up is learn the new stuff especially like wireless. 71 00:04:51,030 --> 00:04:55,020 Make sure you understand wireless make sure that you understand security topics. 72 00:04:55,020 --> 00:04:55,870 Now another tip. 73 00:04:56,160 --> 00:05:01,500 What do you need to prepare is packet Tracy enough and I would say definitely spend time using Packet 74 00:05:01,500 --> 00:05:02,160 Tracer. 75 00:05:02,160 --> 00:05:03,830 So do you need genius 3. 76 00:05:03,830 --> 00:05:05,820 Do you need viral. 77 00:05:05,820 --> 00:05:06,950 Do you need even G. 78 00:05:06,990 --> 00:05:08,310 Do you need physical equipment. 79 00:05:08,310 --> 00:05:09,570 I like those products. 80 00:05:09,570 --> 00:05:13,910 I like the new viral I'll be creating a video on the new viral very soon. 81 00:05:14,010 --> 00:05:15,840 I've already got access to viral 2.0. 82 00:05:15,840 --> 00:05:16,990 Great product. 83 00:05:17,280 --> 00:05:19,460 I love genius 3 love even. 84 00:05:19,650 --> 00:05:21,040 Those products are great. 85 00:05:21,060 --> 00:05:25,470 I really think you should use those products for CCP positions. 86 00:05:25,500 --> 00:05:30,750 However I think packet traces enough if you can get access to physical equipment that always helps. 87 00:05:30,750 --> 00:05:37,110 If you can get access to genie 3 or viral that's great as well because it'll have options that you won't 88 00:05:37,110 --> 00:05:38,100 see and packet tracer. 89 00:05:38,920 --> 00:05:40,520 Okay so I think packet traces enough. 90 00:05:40,530 --> 00:05:46,020 I don't think you need to invest in buying hardware even though I think it's recommended. 91 00:05:46,080 --> 00:05:47,760 It's not a requirement. 92 00:05:47,760 --> 00:05:50,760 I don't think you have to buy viral. 93 00:05:50,760 --> 00:05:55,980 However again I would suggest that you do that as soon as you can because packet Trace is great but 94 00:05:55,980 --> 00:06:01,300 it's at this level and then viral genius 3 even G and physical equipment is at this level. 95 00:06:01,410 --> 00:06:06,090 So if you want to really increase your knowledge if you really want to increase your understanding I'd 96 00:06:06,090 --> 00:06:11,820 recommend that you get those products but it's not required for the CCMA exam for my CS in a course 97 00:06:11,850 --> 00:06:15,960 I'm going to concentrate exclusively on Packet Tracer labs. 98 00:06:15,960 --> 00:06:20,670 So in the past I used to use junior three labs but a lot of people struggled with those labs. 99 00:06:20,940 --> 00:06:25,680 It's quite difficult to setup especially if you're new to Cisco so I'd recommend Packet Tracer. 100 00:06:25,890 --> 00:06:29,020 Easy to setup official product from Cisco. 101 00:06:29,100 --> 00:06:34,870 Brilliant simulation software allows you to simulate many many topics specifically for the CCMA. 102 00:06:35,040 --> 00:06:39,660 I would highly recommend Cisco packet tracer and that's what I'm going to base my course on. 103 00:06:39,990 --> 00:06:46,680 Now one of the best places to look if you're preparing for a Cisco exam is the Cisco outline or Cisco 104 00:06:46,680 --> 00:06:48,770 details of the Exam. 105 00:06:48,940 --> 00:06:51,860 Exam is 120 minutes 200 dash 3 or 1. 106 00:06:51,870 --> 00:06:53,840 This kind of stuff you know ready. 107 00:06:53,850 --> 00:07:00,690 One of the first things I would do if I were you is have a look at the exam topics and I've downloaded 108 00:07:00,750 --> 00:07:04,530 the exam topics here and this is where it got interesting. 109 00:07:05,280 --> 00:07:09,560 OK so let's start with one topic straight away EAI GOP. 110 00:07:09,660 --> 00:07:19,050 There is no easy GOP and no V.P. now when preparing for the exam I highly recommend Wendell Odom's official 111 00:07:19,050 --> 00:07:20,210 cert guides. 112 00:07:20,310 --> 00:07:25,910 I strongly suggest that you buy these guides and you use them lots of good information in here. 113 00:07:25,920 --> 00:07:31,590 I spent a bit of time going through these and I might have missed some stuff but even then I was quite 114 00:07:31,590 --> 00:07:33,640 surprised by a few things. 115 00:07:33,640 --> 00:07:42,180 Okay so in Wendell Odom's official cert guide he does mention G.I. Joe pee in multiple places such as 116 00:07:42,180 --> 00:07:43,990 when you discuss metrics. 117 00:07:44,280 --> 00:07:47,770 So I purchase both the physical books as well as the PDA. 118 00:07:47,790 --> 00:07:49,150 I like having both. 119 00:07:49,150 --> 00:07:55,140 So in this example I'm looking at the IDF version so that I can share it much more easily in this video. 120 00:07:55,140 --> 00:07:56,690 Notice he's got this table here. 121 00:07:56,690 --> 00:08:03,840 He talks about the different types of writing calculations yo GOP calculate based on bandwidth and delay. 122 00:08:03,840 --> 00:08:09,690 So even though my GOP is not in the list of topics for the exam he actually covers it in the official 123 00:08:09,690 --> 00:08:10,180 said guide. 124 00:08:10,980 --> 00:08:14,050 So on the left jump doing searches for a GOP. 125 00:08:14,220 --> 00:08:20,370 And what you'll notice is there's a whole bunch of entries for each GOP such as administrative distance 126 00:08:21,330 --> 00:08:25,380 now it's difficult to understand administer of distance if the only writing protocol you're going to 127 00:08:25,380 --> 00:08:27,540 talk about is oh SPF. 128 00:08:27,540 --> 00:08:31,700 Here we have a table of the administer of distances for various writing protocols. 129 00:08:31,710 --> 00:08:38,680 Notice we have both BGP and EAI GOP as well as ISIS. 130 00:08:38,790 --> 00:08:44,880 So don't just learn o SPF in isolation and just say I'm going to learn SPF and ignore the GOP ignore 131 00:08:44,880 --> 00:08:46,780 BGP ignore ISIS. 132 00:08:46,950 --> 00:08:53,460 Make sure that you understand administer of distances make sure that you understand that if ISIS advertises 133 00:08:53,530 --> 00:08:59,880 Iraq to you or SPF advertises the right to you and GOP advertisers right to you and BGP advertisers 134 00:08:59,880 --> 00:09:04,100 a right to you that you know which route is going to be selected and why. 135 00:09:04,100 --> 00:09:09,110 Now I've previously created videos about this I've created quiz questions about this. 136 00:09:09,150 --> 00:09:10,520 Have a look at this video. 137 00:09:10,520 --> 00:09:19,350 An example where I explain why for instance o SPF is chosen b over EAI GOP or why rep is chosen over 138 00:09:19,660 --> 00:09:22,590 the GOP or over a SPF. 139 00:09:22,590 --> 00:09:26,870 When choosing the best route make sure that you know routes elections. 140 00:09:26,940 --> 00:09:32,180 You really need to understand the stuff for the CCMA exam so make sure that you know a D. 141 00:09:32,350 --> 00:09:35,920 Don't just say I don't need to learn yay GOP. 142 00:09:36,140 --> 00:09:43,570 Make sure you understand it again while talking about the GOP I mentioned V.P. so doing a search for 143 00:09:43,570 --> 00:09:45,060 V.P.. 144 00:09:45,280 --> 00:09:49,720 There's a whole section here talking about veal and trucking protocol and he says before showing more 145 00:09:49,720 --> 00:09:56,440 configuration examples you need to know something about a Cisco protocol called V.P. and he discusses 146 00:09:56,440 --> 00:09:59,260 a whole bunch of stuff including V.P. mode. 147 00:09:59,260 --> 00:10:04,460 Transparent so it's not as if you can just ignore the DP. 148 00:10:04,510 --> 00:10:14,160 He discusses it in multiple places in his student guide and he says this book does not discuss V.P. 149 00:10:14,160 --> 00:10:17,120 as an end to itself for different reasons. 150 00:10:17,160 --> 00:10:19,890 He says it not currently in the blueprint. 151 00:10:19,890 --> 00:10:23,100 And additionally many enterprises choose to disable VTB. 152 00:10:23,340 --> 00:10:26,000 However it still has an effect. 153 00:10:26,010 --> 00:10:33,390 My personal opinion is that I won't remove VTB from my new Cisco CCN a course I'll reduce the amount 154 00:10:33,390 --> 00:10:38,820 of information about it and reduce sort of some of the troubleshooting scenario stuff like that. 155 00:10:38,820 --> 00:10:44,790 But in my new course I will definitely cover VTB going back to the Cisco exam topics. 156 00:10:44,790 --> 00:10:51,130 Make sure that you know the new stuff make sure that you spend time learning the new things. 157 00:10:51,210 --> 00:10:58,170 As an example make sure you know about controllers make sure that you know about Cisco DNA center and 158 00:10:58,170 --> 00:11:03,180 wireless LAN controllers but also don't forget about traditional stuff like what's the difference between 159 00:11:03,180 --> 00:11:04,780 TTP and UDP. 160 00:11:04,800 --> 00:11:08,510 What's the difference between other protocols so like DHEA P versus DNS. 161 00:11:08,520 --> 00:11:10,850 Do you actually understand how those protocols work. 162 00:11:10,860 --> 00:11:12,650 Do you know what they're about. 163 00:11:12,660 --> 00:11:15,770 I mean all this stuff is covered in the outline. 164 00:11:15,900 --> 00:11:18,960 So I found that the exam covered a broad range of topics. 165 00:11:18,960 --> 00:11:24,750 I was surprised by some of the topics that are still asked in the exam but when it comes to addressing 166 00:11:24,750 --> 00:11:27,630 and I missing it right now is submitting. 167 00:11:27,750 --> 00:11:30,560 Make sure that you know your subnet. 168 00:11:31,080 --> 00:11:40,010 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. 169 00:11:40,120 --> 00:11:45,910 Make sure that you know network first host lost hosts and broadcast address. 170 00:11:45,910 --> 00:11:48,870 Make sure that you know that information. 171 00:11:48,940 --> 00:11:57,130 Make sure that you know if you were given a writing table or a subnet ing diagram that you'd know where 172 00:11:57,130 --> 00:12:01,040 devices on the network use tables. 173 00:12:01,080 --> 00:12:07,020 I'm not a big fan of tables but I will be creating videos and publishing them on YouTube as well as 174 00:12:07,020 --> 00:12:11,100 my course worth submitting tables to help you do the stuff quickly. 175 00:12:11,160 --> 00:12:16,950 You've got to be able to look at a writing table you've got to be able to look at a network diagram 176 00:12:17,060 --> 00:12:24,280 you've got to be able to know where a host is so something is always important and it's still important. 177 00:12:24,310 --> 00:12:26,280 Big topics Wi-Fi. 178 00:12:26,470 --> 00:12:31,470 Make sure that you know Wi-Fi topics such as encryption. 179 00:12:31,470 --> 00:12:34,240 So what encryption protocols are used on wireless. 180 00:12:34,330 --> 00:12:39,430 Make sure that you understand the theory of wireless but make sure that you also understand how to configure 181 00:12:39,430 --> 00:12:41,770 stuff through the wireless LAN controller. 182 00:12:41,770 --> 00:12:45,910 Don't skip that section new section in the exam. 183 00:12:46,000 --> 00:12:50,970 Make sure that you spend time on wireless and topics such as virtualization as an example. 184 00:12:51,010 --> 00:12:55,750 I mean that's not pure writing in switching but we've got this convergence of technologies so you need 185 00:12:55,750 --> 00:12:58,240 to understand virtualization as well. 186 00:12:58,240 --> 00:13:01,820 Traditional topics such as quality of service are also important. 187 00:13:01,900 --> 00:13:03,330 My exam was very balanced. 188 00:13:03,340 --> 00:13:08,900 A lot of topics from a whole range of areas for example routing. 189 00:13:09,080 --> 00:13:10,450 Do you understand how writing works. 190 00:13:10,450 --> 00:13:15,870 Do you understand a floating static right vs. a raft such as default right. 191 00:13:15,880 --> 00:13:19,940 Or or a raft that was added by a writing protocol. 192 00:13:19,960 --> 00:13:20,830 Do you understand. 193 00:13:20,860 --> 00:13:27,080 Oh SPF because SPF is the only main protocol in the CCMA. 194 00:13:27,190 --> 00:13:30,560 Make sure that you understand who SPF really really well. 195 00:13:30,640 --> 00:13:36,560 Make sure that you understand elections neighbor adjacencies different types of links. 196 00:13:36,560 --> 00:13:38,680 So here they mentioned point to point. 197 00:13:38,830 --> 00:13:44,440 If you enable a wispy F on a Ethernet interface what kind of network will it be if you enable it on 198 00:13:44,440 --> 00:13:45,550 a point to point link. 199 00:13:45,550 --> 00:13:46,720 What kind of link will it be. 200 00:13:46,840 --> 00:13:50,800 And that's important because once again a lot of when technologies have been removed from the course 201 00:13:50,810 --> 00:13:53,040 BPP has been removed from the course. 202 00:13:53,140 --> 00:13:58,570 But yeah we've got a point to point link in SPF so how would they test you about a point to point link 203 00:13:58,600 --> 00:14:03,280 if you don't have some kind of point to point link so SPF network type could be point to point which 204 00:14:03,280 --> 00:14:07,180 means you need a point to point link so don't just throw out all the old technologies and say I will 205 00:14:07,180 --> 00:14:13,650 not touch anything that has a HD I'll see your point to point type of connection. 206 00:14:13,750 --> 00:14:17,320 I personally will keep a little bit of that in my course. 207 00:14:18,620 --> 00:14:21,980 But you know it's not as big as it was previously. 208 00:14:22,220 --> 00:14:24,170 Okay big section is security fundamentals. 209 00:14:24,650 --> 00:14:29,840 I would spend a lot of time on security fundamentals it's 15 percent of the exam. 210 00:14:29,840 --> 00:14:37,970 Make sure that you understand VPN and make sure that you understand wireless security protocols make 211 00:14:37,970 --> 00:14:45,370 sure that you know how to configure wireless LANs using WPA to using appreciate keys via the gooey. 212 00:14:45,380 --> 00:14:47,350 Make sure that you understand properly. 213 00:14:47,360 --> 00:14:52,650 As an example do you know the difference between authentication authorization and accounting. 214 00:14:52,700 --> 00:14:58,400 So I would spend a lot of time on security fundamentals big part of the course now and then automation 215 00:14:58,400 --> 00:15:00,020 and program ability. 216 00:15:00,020 --> 00:15:04,330 This is where things are going so you would need to know like what is a northbound API. 217 00:15:04,340 --> 00:15:05,420 What's a southbound API. 218 00:15:05,420 --> 00:15:08,360 What protocols would be used on northbound southbound. 219 00:15:09,020 --> 00:15:12,590 My big advice would be make sure you understand what a controller is. 220 00:15:12,590 --> 00:15:17,360 I've discussed this stuff and I've created videos showing a bit of history if you're interested but 221 00:15:17,390 --> 00:15:20,930 I spoke about this stuff on this video many years ago. 222 00:15:20,930 --> 00:15:25,960 What's the difference between separation of control plane data plane. 223 00:15:26,000 --> 00:15:27,510 What is a management plane. 224 00:15:27,530 --> 00:15:30,090 So if you have a controller. 225 00:15:30,500 --> 00:15:36,800 Traditionally we have a device like a rider with the management plane the control plane and the forwarding 226 00:15:36,800 --> 00:15:42,590 plane or data plane within the device but with a controller we take the control plane out of the device 227 00:15:42,590 --> 00:15:44,790 we put it in a centralized controller. 228 00:15:44,780 --> 00:15:50,000 Now in the original open flow model the controller was the brain and the switches became dumb or the 229 00:15:50,000 --> 00:15:51,160 riders became dumb. 230 00:15:51,230 --> 00:15:54,650 That didn't work very well didn't scales or SPF kind of died of death. 231 00:15:54,650 --> 00:15:56,680 That's in the past now. 232 00:15:56,690 --> 00:16:04,190 But the idea with a controller is we can have a controller that for instance controls some aspects of 233 00:16:04,190 --> 00:16:05,150 forwarding. 234 00:16:05,150 --> 00:16:12,970 So in Wendell's CCN a book he spends a lot of time on SD a lot of information on SDI. 235 00:16:13,790 --> 00:16:19,730 I don't know if it's necessary to note that detail but make sure that you understand what is an underlying 236 00:16:19,730 --> 00:16:20,180 network. 237 00:16:20,210 --> 00:16:24,500 Essentially physical devices rather than switches running traditional stuff. 238 00:16:24,500 --> 00:16:30,210 You can however get rid of spanning tree and run a layer 3 network as the Underlay. 239 00:16:30,380 --> 00:16:32,420 Then you run an overlay on top of it. 240 00:16:32,480 --> 00:16:37,190 Now it sounds all complicated but it's just traditional stuff that's got a new spin on it. 241 00:16:37,190 --> 00:16:40,790 I would say so in the old old days and we've done this for years. 242 00:16:40,790 --> 00:16:41,580 The internet. 243 00:16:41,600 --> 00:16:44,450 Think of the Internet as an underlay. 244 00:16:44,450 --> 00:16:48,370 It doesn't understand what's going across it necessarily. 245 00:16:48,380 --> 00:16:53,420 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 246 00:16:53,420 --> 00:16:58,280 traditional telephone network where the switches in the cloud were intelligent and the phones were dumb. 247 00:16:58,280 --> 00:17:03,180 Then the intelligence was put on the phones and the using Skype as an example. 248 00:17:03,290 --> 00:17:10,920 And the networking core became dumb and we just simply made calls across the Internet using Skype. 249 00:17:11,540 --> 00:17:14,260 So the traditional telephony network was intelligent. 250 00:17:14,260 --> 00:17:19,400 It was replaced with an IP call that was essentially dumb it didn't understand all the applications 251 00:17:19,400 --> 00:17:20,260 going across it. 252 00:17:20,450 --> 00:17:26,390 And then we made calls across the Internet using Skype with the intelligence in the endpoints or in 253 00:17:26,390 --> 00:17:32,270 the controllers which could be as an analogy call manage express or whatever controller we're using 254 00:17:32,270 --> 00:17:35,170 to set up the calls using IP devices. 255 00:17:35,210 --> 00:17:39,850 Now here in SGA we've got an underlay think of that kind of like the Internet. 256 00:17:39,860 --> 00:17:46,480 So we've got just switches routers they are dumb to a point and then we put an overlay on top of it. 257 00:17:46,480 --> 00:17:49,750 So we build a whole network on top of it using Vieques land. 258 00:17:49,760 --> 00:17:54,290 Now it sounds complicated it's just tunnels but the intelligence is that can automatically be built 259 00:17:54,530 --> 00:18:01,220 to apply policy so we can have a policy and an SD server so we could have a policy on a controller and 260 00:18:01,220 --> 00:18:04,640 then apply the policy to the overlay not to the Underlay. 261 00:18:04,910 --> 00:18:11,540 So rather than trying to manually configure access lists on individual devices we apply the policy and 262 00:18:11,540 --> 00:18:14,900 this is the whole idea with intent based networking. 263 00:18:14,900 --> 00:18:20,980 We apply a policy on the controller and then that's going to configure the devices with us overlay network. 264 00:18:20,990 --> 00:18:27,500 So from me to you there might be a 20 switches or 20 writers on the Internet as an example but when 265 00:18:27,500 --> 00:18:31,050 we set up the IP SAC tunnel logically it's a hop from me to you. 266 00:18:31,070 --> 00:18:31,950 Same kind of idea. 267 00:18:31,950 --> 00:18:35,120 Here we've got a whole bunch of physical devices as the Underlay. 268 00:18:35,120 --> 00:18:37,700 We put an overlay on top of it. 269 00:18:38,030 --> 00:18:39,860 Make sure you understand those concepts. 270 00:18:39,860 --> 00:18:46,560 Make sure that you understand rest but arrest in the definite exam there's obviously a lot more about 271 00:18:46,560 --> 00:18:46,890 that. 272 00:18:46,950 --> 00:18:52,590 Make sure that you understand differences between Puppet Chef and sensible so answerable as an example 273 00:18:52,590 --> 00:18:53,820 doesn't need an agent. 274 00:18:53,850 --> 00:18:56,300 It's an agent less implementation. 275 00:18:56,520 --> 00:19:01,920 So I've created a whole sensible course so I'll take some of that experience and knowledge and attitude 276 00:19:01,920 --> 00:19:03,180 my new CCN course. 277 00:19:03,390 --> 00:19:09,870 Make sure that you understand that with Ansel it's kind of like with python scripts I can just SS H 278 00:19:09,870 --> 00:19:12,780 to the devices and make configuration changes on them. 279 00:19:12,900 --> 00:19:16,950 But with puppet and chef with puppet you you can do some interesting things. 280 00:19:16,950 --> 00:19:24,990 But the idea is you run an agent on the device and you don't use SSA to talk to the agent using HDP. 281 00:19:25,000 --> 00:19:29,540 So using a web based protocol rather than traditional SSA. 282 00:19:29,940 --> 00:19:35,370 So the idea is as your control over your controlling device or your management device talks to the agent 283 00:19:35,370 --> 00:19:39,740 on the device that then configure the device but with sensible its agent lists. 284 00:19:39,750 --> 00:19:45,180 We're not running an agent or special software on the rudders and switches we are connecting directly 285 00:19:45,210 --> 00:19:47,550 to them from a server. 286 00:19:47,550 --> 00:19:51,970 Make sure you can also interpret Jason encoded data. 287 00:19:52,050 --> 00:19:56,790 I was quite surprised by that one but yeah make sure you spend a bit of time on automation and program 288 00:19:56,790 --> 00:20:00,900 ability but don't get stuck on this topic. 289 00:20:00,930 --> 00:20:02,250 It's a new topic in the exam. 290 00:20:02,250 --> 00:20:03,590 Don't get stuck on it. 291 00:20:03,600 --> 00:20:08,280 Notice security fundamentals has more information or that is more important. 292 00:20:08,280 --> 00:20:11,790 15 percent IP services is 10 percent. 293 00:20:11,880 --> 00:20:21,340 Talking about traditional stuff like the HP DNS A.P. is an MP so it's an MP He's been a run for years. 294 00:20:21,360 --> 00:20:26,380 Do you understand which underlying protocols are used by these upper layer protocols. 295 00:20:26,490 --> 00:20:30,000 So which protocol does s an MP use. 296 00:20:30,000 --> 00:20:35,160 Is it UDP is a TTP which protocol does SSA to use TTP UDP. 297 00:20:35,220 --> 00:20:39,350 Make sure that you understand various protocols and the underlying protocols under them. 298 00:20:39,450 --> 00:20:41,580 So I mean I could list all of these topics. 299 00:20:41,580 --> 00:20:45,530 I mean my exam was very broad covered a whole bunch of topics. 300 00:20:45,680 --> 00:20:47,450 I think it was a very balanced exam. 301 00:20:47,450 --> 00:20:51,840 I think it was a good exam Okay so hopefully you've learned something.
