WEBVTT 1 00:00.000 --> 00:04.040 It's always tempting to want to just move on to the next subject, but we've 2 00:04.040 --> 00:04.520 just covered 3 00:04.520 --> 00:06.280 some really big ones. 4 00:06.280 --> 00:10.280 Software-defined weigh-in, software-defined access, these are massive new 5 00:10.280 --> 00:11.200 technologies, 6 00:11.200 --> 00:13.820 relatively new technologies, because at this point they've been around for 7 00:13.820 --> 00:14.280 quite a few 8 00:14.280 --> 00:17.430 years, but in the grand scheme of things, routing and switching didn't change a 9 00:17.430 --> 00:17.760 whole 10 00:17.760 --> 00:19.280 lot for a long time. 11 00:19.280 --> 00:22.900 And then all of a sudden we get software-defined infrastructure, so SD access 12 00:22.900 --> 00:23.960 completely changes 13 00:23.960 --> 00:27.810 the way we deploy access layer, switching, and software-defined win completely 14 00:27.810 --> 00:28.280 changes 15 00:28.280 --> 00:31.480 the way we deploy our wide area networks. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 15 00:28.280 --> 00:31.480 the way we deploy our wide area networks. 16 00:31.480 --> 00:36.860 And so before we move on, let's go ahead and take a moment to pause, hit the 17 00:36.860 --> 00:37.680 brakes, 18 00:37.680 --> 00:42.030 take a breath, and remember everything that we've been learning, because there 19 00:42.030 --> 00:42.960 was a lot 20 00:42.960 --> 00:43.960 of information. 21 00:43.960 --> 00:49.030 It was hard for me to pack all of that information we talked about into a 22 00:49.030 --> 00:50.400 decent summary, because 23 00:50.400 --> 00:52.240 there was just so much. 24 00:52.240 --> 00:55.960 So let's be sure to take a few moments here to remember what we've learned to 25 00:55.960 --> 00:56.400 lock it 26 00:56.400 --> 01:01.090 in for the future, and hey, bookmark this skill as well, because later on when WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 26 00:56.400 --> 01:01.090 in for the future, and hey, bookmark this skill as well, because later on when 27 01:01.090 --> 01:01.360 you're 28 01:01.360 --> 01:05.690 preparing to maybe go take the exam, rather than going back through every 29 01:05.690 --> 01:06.640 single skill, 30 01:06.640 --> 01:10.370 maybe we can target some of these review skills, say let's just go through that 31 01:10.370 --> 01:10.640 . 32 01:10.640 --> 01:13.910 And the goal here is obviously number one, we want to answer the questions and 33 01:13.910 --> 01:14.360 get them 34 01:14.360 --> 01:19.110 right, but don't be discouraged by getting the answers wrong either, because 35 01:19.110 --> 01:19.560 what that 36 01:19.560 --> 01:22.800 allows us to do is say, "Hey, I need to work on that." 37 01:22.800 --> 01:25.920 It helps us to identify our areas of weakness. 38 01:25.920 --> 01:29.680 Not one of us has all of this memorized and all of this down, so when we're 39 01:29.680 --> 01:30.440 going through WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 39 01:29.680 --> 01:30.440 going through 40 01:30.440 --> 01:33.900 this, make sure to flag any questions, say, "Hey, I need to learn more about 41 01:33.900 --> 01:34.760 that or remember 42 01:34.760 --> 01:35.760 more about that." 43 01:35.760 --> 01:41.240 I can go back to the skill that's referenced in the quizzes and make sure that 44 01:41.240 --> 01:42.200 I can answer 45 01:42.200 --> 01:44.080 that question moving forward. 46 01:44.080 --> 01:47.050 So as far as the format's concerned, we're going to do some quiz questions, we 47 01:47.050 --> 01:47.440 're going 48 01:47.440 --> 01:50.040 to do some challenges, but let's go and dive into this review.
