I interviewed with Amazon and there is no NDA. No self respecting company will use an NDA, because no one worth their salt with even entertain doing an interview with you under NDA. Amazon interview was fair, not harsh. Reasonable. Certainly no walk in the park, and long. Well I definitely signed an NDA when interviewing with them. Really? That's odd. Was that for an interview stage or was it past that point and like after you were offered a position? I had around 6 interviews total. What were your impressions and how did it go? Mine was decent. Only two interviews. One phone, then they flew me out for a few days. They did one full day of interviews then paid for me to stay in Seattle to get to know the city and make moving decisions. The whole process was pretty smooth and well done. Nothing to knock your socks off, but better than Facebook, not as good as most Wall St. firms. But way better than an average Fortune 100 firm. Very professional. Took me out to lunch. Interview process was reasonable, not some silly "did you happen to memorize the right answers" kind of BS.

  It only seems like private isn't available because no one does that. Why wants private cloud? no one, not really. It's essentially a dumb idea. It basically exists for crazy people and governments where "good decision making" isn't a factor. But hybrid is ruled out in both of those cases either because it doesn't support the "crazy" or the legal government requirement.

Nobody in their right mind would do that. Again, like Scott, why add in things that were never part of any point? Let me refresh the point: Scott originally compared full blown Windows Desktop GUI plus web browser and other app RAM usage, to a minimal gui-less Linux server RAM usage. This was what I was arguing against, that the comparison was not fair and was not set up correctly. Except I was specifically making the comparison on use case, not on technology. So the bases for your correction doesn't make sense. I pointed out that one was assumed to have a GUI and be used graphically, and one was assumed to be a headless server. So my comparison wasn't Windows vs Linux, it was use case vs. use case. What use case comparison involves Windows GUI + web browsing versus GUI-less Linux minimal install? Lots. Like when you are using RDS versus using a PBX. It's that we are comparing different use cases is the point. Not comparing the same use case in two different places.

Will server issues every go away? Then.. no. Is IT always responsible for servers? Then... yes. Will servers always exist? Then... yes. Will servers always have issues? Then... yes.

  @connorsoliver said in Troubleshooting Common Hardware Problems - CompTIA A+ 220-1001 Prof Messer: If you get the blue screen of death on windows, do you have to reinstall the operating system? Or is there a simpler way to fix it? Most of the time, you do nothing. It happens to every system, sometimes. It's just a crash. You will 99% of the time just restart the computer and move on.

  @Dashrender said in Cloud Services - CompTIA A+ 220-1001 Prof Messer: @connorsoliver said in Cloud Services - CompTIA A+ 220-1001 Prof Messer: What would the benefits of using VDI be for personal use? One thing we're going to likely see in the future is VDI for gaming. You'll play games from your mobile device or your whatever device and it will really be running in a VDI in some DC somewhere. While it's not wide spread for consumers yet, it very likely will be, just consumers won't realize it. I doubt it, with so many SaaS services for gaming already available, doing an IaaS one seems unlikely. Who would want that?

  @IRJ said in Troubleshooting Hard Drives - CompTIA A+ 220-1001 Prof Messer: @connorsoliver said in Troubleshooting Hard Drives - CompTIA A+ 220-1001 Prof Messer: Is there a way to fix the physical hard drive? There is but there really isnt any situations where you would do that unless you had to recover data. If a physical hard drive becomes damage, you generally cannot trust the drive anymore and dispose of it. Plus they are cheap (relatively) and even if you could repair it and trust it, it's a costly and difficult thing to do to repair a drive when it is effectively cheap and easy to just buy a new one.

It's just a term. One that they thought would be common, but isn't. Really no one used it and it's just silly. LAN and WAN still describe all of the real types that matter. The idea of a MAN is kind of meaningless. So while they kind of exist regularly, no one talks about them. It is also implied that it is something managed by the ISP (aka telcos back when it was a term actually used). Used to imply, yeah. Today it is often down by owned wireless. But the first MAN I worked on was one we built privately in DC. No telecoms involved. That was early 2000. First one I worked with was in some Citibank offices in the mid-late 90's in St. Louis. Telecoms involved only as far as providing the clean pairs of copper. Otherwise, Citi did it all themselves also. I was similar. AT&T provided the fiber in case, but we managed everything else.

Also why would you use workgroup instead of Windows Domain? Is it a cost issue? "Home Group" was just a fancy name for network sharing without AD on Windows computers.

  @mary said in Windows Control Panel - CompTIA A+ 220-1002 Prof Messer: This may be basic but, can cookies damage your system in anyway? It's one of those things that a lot of sites require you to accept, and an average user just accepts them. So the cookie itself is just a text file. A tiny one. That's it. So the cookie itself does nothing. The issues are if the cookie has something in the text and a browser reads it and does something it shouldn't because of it. But realistically, that's not going to happen. The main concerns around cookies are that they help people to track you, but you need to be tracked. We've been conditioned to thinking that being tracked is a bad thing, but cookies are what lets us track you from post to post here in RoIT for example.

  @scottalanmiller said in Windows Firewall with Advanced Security - CompTIA A+ 220-1002 Prof Messer: @JaredBusch well it's good to be explicit that Windows Defender and Windows Defender Firewall are two different products. But also Windows Firewall isn't a real name, either. Windows Defender Firewall is the name of the Windows firewall. So using "Windows Firewall" or "firewall by Windows Defender" are essentially the same - lose descriptions of the brand name. All make sense. Good to remember that the pieces are discrete. The best full statement is "the Windows firewall is Windows Defender Firewall." True, but until Windows 10, it was simply called Windows Firewall. So that is a correct legacy term. Vista introduced the longer term Windows Firewall with Advanced Security in the MMC snap in. It stayed those two terms until Windows 10.

  @mary said in Windows Task Manager - CompTIA A+ 220-1002 Prof Messer: Do any of you use task manager to troubleshoot what if there is an issue with a PC? I'm trying to get a sense of the steps people go through. Constantly. If working on Windows, it's the "go to" starting point to "see what is going on." It's not a once in a while tool, it's the "might as well just always start there" tool. It gives you a quick glance to see what the system itself is doing. If CPU or RAM is maxed out, or a process list looks crazy, that's almost always what is wrong no matter what it is that you came to look at! I mean if I'm looking for a missing folder of cat pictures, I don't open the task manager first. Nor if I'm installing a new printer. But if I am troubleshooting anything going on with the system, that's the first place to look. The Resource Monitor is also pretty fantastic.

They are supplied to you by whomever you bought them from. There is no situation where there isn't someone providing them to you. Unless he was talking about the LAN side. In that case it is the Network Engineer who decides the scope of the LAN and chooses an appropriate sized CIDR and private IP address to use.

  @scottalanmiller said in Using IP Addresses - CompTIA A+ 220-1001 Prof Messer: @connorsoliver said in Using IP Addresses - CompTIA A+ 220-1001 Prof Messer: When using an SSL VPN, if the VPN concentrator decrypts the data being sent, wouldn't it be possible for someone to capture the data and also decrypt it? Possible, sure. But very, very hard. The VPN concentrator has the keys, someone intercepting the traffic presumably does not. The point of VPN encryption is to make it so hard to decrypt the data that you don't care if they see it. It's about making something safe enough that we assume we will send it in the open and not worry. So we assume that people capture that data constantly - but we have made it so hard to use, that they can't do it. We more than assume that - we pretty much know the NSA is doing that after the Snowden leaks.

  @connorsoliver said in Wireless Network Technologies - CompTIA A+ 220-1001 Prof Messer: Why isn't zigbee used for computers? 802.15.4 (aka ZigBee) has a speed of 250 Kb/s which is SO slow. High enough to make two phone calls, but that's it. Not enough to really "do" anything. It's plenty fast to send sensor data or basic instructions, but way too slow for any computer usage. Old 802.11b, the slowest computer wireless tech, was 11Mb/s, which is 44x faster than Zigbee and considered worthless because it is so slow. We want our wireless in the 100Mb/s+ range these days.

  @connorsoliver said in Network Services - CompTIA A+ 220-1001 Prof Messer: What exactly is bandwidth shaping? I've never herd that term before. That's an uncommon term, we normally say "traffic shaping". But same difference. It's a form of Quality of Service, or related to quality of service, where traffic is monitoring and available performance for different types of traffic is adjusted to make some protocols or tasks perform better than others. For example, with traffic shaping you can make teleconferencing, phone calls, and posting on MangoLassi get the best performance, while streaming Netflix and IHeartRadio get the slow lane. Unlike traditional QoS, it's about "encouraging" patterns rather than enforcing. With normal QoS, phone traffic might get priority, period. But with shaping, it gets more "weight" in the algorithm, but doesn't get a guarantee of always going first.

  But realistically, if you started working in IT full time today, and did normal small business IT work all the time, you might not interact with IPv6 at all for a few years yet.

  @mary said in Windows Administrative Tools - CompTIA A+ 220-1002 Prof Messer: Is there a list anywhere of the Windows command prompts, or do you usually look at the help to look at options? I realize the more seasoned IT person would have a lot of these committed to memory, but just starting out this is a bit overwhelming. There seem to be a lot of them to keep track of. Kind of. There are some built in tools to the shell itself, and some standard Windows tools that you can call. but keep in mind that you can add an unlimited number of additional ones, because all you are doing is calling installed applications. So while there are lists of the ones built in, most people have loads and loads of ones that are not.

  @Dashrender said in An Overview of Windows 10 - CompTIA A+ 220-1002 Prof Messer: @mary said in An Overview of Windows 10 - CompTIA A+ 220-1002 Prof Messer: First thing I did was get back to the old school desktop. Not sure what you mean? As for changing the start menu - I used to do that to.. but as a consultant, going around all over the place, that just become a waste of time. I learned to use the new defaults that MS provides. it's one thing to setup the machine you use on a daily basis for max efficiency, but the rest, just use them as the default. Especially in IT, we aren't end users. End users customize because they have one system and its purpose is to make them efficient. IT has to constantly work on a variety of systems and we need to be able to use them as they are. One of the best lessons I got from my first IT "teacher" (at uni) was as a system admin to never customize anything because when you need to get work done, those customizations won't be there.
