1 00:00:00,090 --> 00:00:01,560 In this lesson, we're going to talk about 2 00:00:01,560 --> 00:00:04,530 steps four and five of the troubleshooting methodology, 3 00:00:04,530 --> 00:00:06,540 which is to establish a plan of action 4 00:00:06,540 --> 00:00:09,720 and to implement the solution or escalate as necessary. 5 00:00:09,720 --> 00:00:11,190 Now, CompTIA likes to word this 6 00:00:11,190 --> 00:00:14,190 as establish a plan of action to resolve the problem 7 00:00:14,190 --> 00:00:15,750 and implement the solution, 8 00:00:15,750 --> 00:00:19,020 and also refer to the vendor's instructions for guidance. 9 00:00:19,020 --> 00:00:21,060 Now, when we're establishing a plan of action 10 00:00:21,060 --> 00:00:23,580 to resolve the problem, what we are trying to do 11 00:00:23,580 --> 00:00:25,740 is figure out how are we going to solve 12 00:00:25,740 --> 00:00:28,260 that underlying probable cause that we identified 13 00:00:28,260 --> 00:00:31,260 back in step two and verified in step three. 14 00:00:31,260 --> 00:00:33,930 At this point, we haven't actually solved the problem, 15 00:00:33,930 --> 00:00:34,980 but we've identified it 16 00:00:34,980 --> 00:00:36,870 and we've verified that that problem exists 17 00:00:36,870 --> 00:00:38,700 and we know what the problem is. 18 00:00:38,700 --> 00:00:42,180 So now we need to establish our plan of action. 19 00:00:42,180 --> 00:00:44,760 For example, if we are dealing with a power problem 20 00:00:44,760 --> 00:00:47,250 and we've identified that the power supply is bad, 21 00:00:47,250 --> 00:00:49,740 we can then do a couple of different things. 22 00:00:49,740 --> 00:00:52,080 We could repair it, we could replace it, 23 00:00:52,080 --> 00:00:54,510 or we can issue a workaround. 24 00:00:54,510 --> 00:00:57,060 Now, when we repair something, we need to determine 25 00:00:57,060 --> 00:00:59,550 how much is it going to cost to repair something. 26 00:00:59,550 --> 00:01:01,950 For example, my kid has an iPad 27 00:01:01,950 --> 00:01:03,840 and they actually cracked the screen on it. 28 00:01:03,840 --> 00:01:06,240 Now I can fix that screen, but what I found out 29 00:01:06,240 --> 00:01:08,310 was it wasn't worth the repair. 30 00:01:08,310 --> 00:01:11,760 The cost to get a new screen for that iPad was about 350 31 00:01:11,760 --> 00:01:15,000 to $400, and that's if I was going to install it myself. 32 00:01:15,000 --> 00:01:18,180 The cost of a brand new iPad was only about 450 33 00:01:18,180 --> 00:01:20,310 to $500 on sale that week. 34 00:01:20,310 --> 00:01:22,950 So I just decided it wasn't worth repairing 35 00:01:22,950 --> 00:01:24,210 this 2-year-old device, 36 00:01:24,210 --> 00:01:27,000 and so instead, I opted for option number two, 37 00:01:27,000 --> 00:01:28,980 which is to replace the device. 38 00:01:28,980 --> 00:01:31,140 Now, in this case, instead of replacing the screen, 39 00:01:31,140 --> 00:01:33,480 I actually replaced the entire iPad 40 00:01:33,480 --> 00:01:35,070 because it made more fiscal sense 41 00:01:35,070 --> 00:01:36,690 to replace the entire device 42 00:01:36,690 --> 00:01:38,370 and get a new one that's going to last another two 43 00:01:38,370 --> 00:01:41,370 or three years than it was to repair that single component 44 00:01:41,370 --> 00:01:44,310 because other components could then start failing as well. 45 00:01:44,310 --> 00:01:46,020 So this is one of those judgment calls 46 00:01:46,020 --> 00:01:47,160 that you're going to have to make, 47 00:01:47,160 --> 00:01:50,130 and generally in an organization, you're going to get some left 48 00:01:50,130 --> 00:01:53,010 and right guidelines of when it makes sense to repair 49 00:01:53,010 --> 00:01:56,790 versus replace a given component or system in your network. 50 00:01:56,790 --> 00:01:59,280 Another option you have is a workaround. 51 00:01:59,280 --> 00:02:01,830 Now, not all problems you encounter are going to be life 52 00:02:01,830 --> 00:02:04,590 and death critical things that must be solved today 53 00:02:04,590 --> 00:02:06,120 at all costs. 54 00:02:06,120 --> 00:02:08,430 Now, in some cases, it might be too time consuming 55 00:02:08,430 --> 00:02:11,220 to repair something or too expensive to replace it, 56 00:02:11,220 --> 00:02:14,880 and in those cases it may be better just to do a workaround. 57 00:02:14,880 --> 00:02:17,520 For example, let's say I'm on a business trip 58 00:02:17,520 --> 00:02:19,710 and I have a really expensive laptop with me. 59 00:02:19,710 --> 00:02:22,830 But as I was out there working, I actually dropped it 60 00:02:22,830 --> 00:02:26,070 and the screen cracked, and now I can't work on this laptop. 61 00:02:26,070 --> 00:02:27,810 Now I'm not going to be home from this business trip 62 00:02:27,810 --> 00:02:29,070 for another two or three weeks, 63 00:02:29,070 --> 00:02:31,890 and I need to have this machine working right now. 64 00:02:31,890 --> 00:02:33,870 So I have a couple of options. 65 00:02:33,870 --> 00:02:35,850 I can actually replace the screen right now 66 00:02:35,850 --> 00:02:38,430 by going and doing an emergency overnight fix 67 00:02:38,430 --> 00:02:41,340 that might cost me two or three times as much money. 68 00:02:41,340 --> 00:02:43,170 Or I can actually delay 69 00:02:43,170 --> 00:02:45,600 because I know somebody there has the tools, technology, 70 00:02:45,600 --> 00:02:47,520 and ability to replace that screen for me 71 00:02:47,520 --> 00:02:49,110 at a very low cost. 72 00:02:49,110 --> 00:02:50,010 Now, in the meantime, 73 00:02:50,010 --> 00:02:51,810 I still need to be able to get work done. 74 00:02:51,810 --> 00:02:55,380 So do I want to spend $2,000 to fix this machine right now 75 00:02:55,380 --> 00:02:56,940 that'll last me in the next two weeks. 76 00:02:56,940 --> 00:02:59,610 Or if I wait two weeks until I get back to the office, 77 00:02:59,610 --> 00:03:01,710 it might only cost me $200. 78 00:03:01,710 --> 00:03:04,980 Well, there's a third option, I can create a workaround. 79 00:03:04,980 --> 00:03:06,330 In this case, and I might go to 80 00:03:06,330 --> 00:03:09,660 the local office supply store and buy a $99 monitor 81 00:03:09,660 --> 00:03:10,950 to use for the next two weeks 82 00:03:10,950 --> 00:03:12,840 while I'm working out of my hotel room. 83 00:03:12,840 --> 00:03:15,150 That would work just fine as a workaround, 84 00:03:15,150 --> 00:03:17,010 but not as a long-term replacement 85 00:03:17,010 --> 00:03:18,780 because this is a laptop after all, 86 00:03:18,780 --> 00:03:20,430 and I don't want to have to always carry around 87 00:03:20,430 --> 00:03:22,950 a big monitor with me every place I go. 88 00:03:22,950 --> 00:03:25,260 So in this case, I might buy $100 monitor, 89 00:03:25,260 --> 00:03:27,690 set it up in my hotel room, use it while I'm there, 90 00:03:27,690 --> 00:03:30,510 and then donate it to charity as I leave that city. 91 00:03:30,510 --> 00:03:32,010 I've actually done this several times, 92 00:03:32,010 --> 00:03:33,690 not because of a broken monitor, 93 00:03:33,690 --> 00:03:35,430 but because when I'm working in a hotel room 94 00:03:35,430 --> 00:03:38,610 and I'm going to be someplace for three or four or five weeks, 95 00:03:38,610 --> 00:03:41,520 I don't want to have to work off a little 13 inch monitor. 96 00:03:41,520 --> 00:03:45,030 So instead, I might go to the local store and buy a 20, 24 97 00:03:45,030 --> 00:03:48,750 or 27 inch monitor for about 100 or $150, 98 00:03:48,750 --> 00:03:51,210 use it for the three to five weeks that I'm in that area, 99 00:03:51,210 --> 00:03:54,060 and then donate it to a local charity before I leave. 100 00:03:54,060 --> 00:03:56,100 That way I can use the large screen that I need 101 00:03:56,100 --> 00:03:57,420 for that three to five weeks 102 00:03:57,420 --> 00:03:58,800 without having to carry it onto a plane 103 00:03:58,800 --> 00:04:00,270 as I fly all over the place 104 00:04:00,270 --> 00:04:02,160 and so I've actually done this several times, 105 00:04:02,160 --> 00:04:03,750 especially when I'm going to someplace 106 00:04:03,750 --> 00:04:05,280 for a longer period of time. 107 00:04:05,280 --> 00:04:06,990 If I'm only going to be there for a day or two, 108 00:04:06,990 --> 00:04:09,210 I'll just use my smaller laptop monitor. 109 00:04:09,210 --> 00:04:11,790 But if I'm going to be gone for a significant amount of time, 110 00:04:11,790 --> 00:04:14,100 I will buy an extra monitor as a workaround 111 00:04:14,100 --> 00:04:16,860 to give me the larger screen that I need when I'm working. 112 00:04:16,860 --> 00:04:18,000 So keep this in mind. 113 00:04:18,000 --> 00:04:19,410 When you're dealing with a problem, 114 00:04:19,410 --> 00:04:21,870 usually you're going to have three main things you can do 115 00:04:21,870 --> 00:04:23,400 as part of your plan of action. 116 00:04:23,400 --> 00:04:25,260 You can repair it, you can replace it, 117 00:04:25,260 --> 00:04:27,600 or you can create a workaround. 118 00:04:27,600 --> 00:04:30,120 Now, in addition to figuring out what you're going to do, 119 00:04:30,120 --> 00:04:32,730 you also need to plan how it's going to be done, 120 00:04:32,730 --> 00:04:35,670 and this is known as establishing a plan of action. 121 00:04:35,670 --> 00:04:38,190 Now, when you devise your plan of action, you're going to say, 122 00:04:38,190 --> 00:04:40,230 how much resources, how much time, 123 00:04:40,230 --> 00:04:42,000 and how much cost is there going to be associated 124 00:04:42,000 --> 00:04:43,920 with the given solution you're choosing? 125 00:04:43,920 --> 00:04:46,530 Also, if there's any impacts to the other users 126 00:04:46,530 --> 00:04:49,230 or other systems, you need to identify those as well 127 00:04:49,230 --> 00:04:50,760 and depending on your corporate policies 128 00:04:50,760 --> 00:04:53,220 and procedures, you might need to seek permission 129 00:04:53,220 --> 00:04:55,410 to be able to go through with your plan. 130 00:04:55,410 --> 00:04:57,510 For example, when I was the IT director 131 00:04:57,510 --> 00:05:00,540 for a large organization, I couldn't just reboot the servers 132 00:05:00,540 --> 00:05:02,730 anytime of the day or night that I felt like it. 133 00:05:02,730 --> 00:05:04,380 I had to go up to the executives 134 00:05:04,380 --> 00:05:06,727 and say, "Hey, here's my plan for the upgrade 135 00:05:06,727 --> 00:05:08,887 "we're going to do, I want to reboot the servers. 136 00:05:08,887 --> 00:05:10,417 "We're going to have five minutes of downtime 137 00:05:10,417 --> 00:05:11,797 "during that reboot period. 138 00:05:11,797 --> 00:05:13,717 "What is a good time for the business 139 00:05:13,717 --> 00:05:15,300 "for me to be able to do this?" 140 00:05:15,300 --> 00:05:16,133 And they might say, 141 00:05:16,133 --> 00:05:17,737 "Between two and three in the morning 142 00:05:17,737 --> 00:05:20,407 "would be a great time to do it because everyone's asleep. 143 00:05:20,407 --> 00:05:22,327 "You don't want to do it in the middle of the afternoon 144 00:05:22,327 --> 00:05:23,587 "in prime business hours 145 00:05:23,587 --> 00:05:25,200 "when we're trying to use the network." 146 00:05:25,200 --> 00:05:26,880 And so these are things you're going to have to figure out 147 00:05:26,880 --> 00:05:28,470 based on your organization 148 00:05:28,470 --> 00:05:31,020 and how you're going to implement your plan of action. 149 00:05:31,020 --> 00:05:32,010 Another thing to keep in mind 150 00:05:32,010 --> 00:05:34,200 is that a lot of systems work together, 151 00:05:34,200 --> 00:05:36,390 and so if you're working on a single machine, 152 00:05:36,390 --> 00:05:39,120 such as an end user's machine, it probably isn't going to be 153 00:05:39,120 --> 00:05:41,820 that big of a deal and you can reboot it without permission. 154 00:05:41,820 --> 00:05:44,460 But if you're working on a server, like a file server, 155 00:05:44,460 --> 00:05:46,800 a print server, or a domain controller, 156 00:05:46,800 --> 00:05:49,950 this can have a massive effect across the organization. 157 00:05:49,950 --> 00:05:52,500 For example, if you're working on the domain controller 158 00:05:52,500 --> 00:05:54,480 and you reboot that, this can prevent users 159 00:05:54,480 --> 00:05:56,760 from being able to log into their own workstations 160 00:05:56,760 --> 00:05:58,560 because the domain controller isn't available 161 00:05:58,560 --> 00:06:00,300 to do that authentication. 162 00:06:00,300 --> 00:06:02,040 On the other hand, if you're doing something 163 00:06:02,040 --> 00:06:04,500 like a file server, this is actually going to disconnect 164 00:06:04,500 --> 00:06:07,500 all the users from the file server, but they can still print 165 00:06:07,500 --> 00:06:09,060 and they can still log into the servers 166 00:06:09,060 --> 00:06:10,050 because the print server 167 00:06:10,050 --> 00:06:12,120 and domain controller may still be up. 168 00:06:12,120 --> 00:06:14,400 So it's important to understand what is the impact 169 00:06:14,400 --> 00:06:16,470 of your particular solution that you're doing 170 00:06:16,470 --> 00:06:18,570 as part of your plan of action. 171 00:06:18,570 --> 00:06:20,580 Once you have that plan of action in place 172 00:06:20,580 --> 00:06:22,290 and you've got the authority to move ahead, 173 00:06:22,290 --> 00:06:24,390 you can then implement your solution. 174 00:06:24,390 --> 00:06:26,550 This might be installing a new update, 175 00:06:26,550 --> 00:06:29,580 replacing a piece of hardware or rebooting a system. 176 00:06:29,580 --> 00:06:30,870 Regardless of what it is, 177 00:06:30,870 --> 00:06:32,820 you need to make sure you stick with the plan of action 178 00:06:32,820 --> 00:06:35,280 you've created and follow the steps that you've outlined 179 00:06:35,280 --> 00:06:37,710 because that's what everyone is expecting you to do. 180 00:06:37,710 --> 00:06:39,240 If you have a change to that plan, 181 00:06:39,240 --> 00:06:41,640 you're going to need to go back and get authorization again, 182 00:06:41,640 --> 00:06:43,890 because remember, any changes could implement 183 00:06:43,890 --> 00:06:46,470 the larger system and other things across the network 184 00:06:46,470 --> 00:06:47,760 that you may not be aware of. 185 00:06:47,760 --> 00:06:49,230 So you need to keep that in mind 186 00:06:49,230 --> 00:06:50,160 and make sure you're always working 187 00:06:50,160 --> 00:06:51,720 as part of the larger team 188 00:06:51,720 --> 00:06:53,520 when you are establishing your plan of action 189 00:06:53,520 --> 00:06:55,083 and implementing your solution.
