@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.

@mary said in Network Command Line Tools - CompTIA A+ 220-1002 Prof Messer: Is it ok to have any packet loss when pinging another computer? It's not a crime or anything There is always "some" packet loss, but in a healthy network it is super low, like one out of one hundred thousands packets. If you are doing a ping and seeing packets missed regularly, something is wrong. On a wired network, this implies bad equipment, cabling, or EM interference. On wireless it means your signal isn't clean. Obviously wifi is going to lose packets way more than a cabled connection, and copper way more than optical. But it should still be essentially zero on a healthy network.

Partitioning does a few things. It makes a single device (like a hard drive) appear like more than one. You can use this to be able to access multiple file systems, for one thing. On Windows this isn't as big as really there is just FAT32, NTFS, and ReFS. But on Linux there are dozens of reasonable ones and we use partitioning for that all of the time. Another is risk domains. You might have something that likes to fill up a disk quickly and you won't to isolate it from other parts of the system. that way if it fills up it doesn't kill the OS or the database. Popular for log directories. You might want to forcibly keep users from using too much space for personal files, so you limit it via a partition size. Uncommon, but possible. You often take backups at the partition level. So it is very common to put critical data on an individual partition so that an image based tool like Veeam can backup what is critical differently than stuff that is less critical. Snapshots are normally at the partition level as well, so multiple partitions means you get snapshot flexibility and performance benefits.

@mary said in Windows in the Enterprise - CompTIA A+ 220-1002 Prof Messer: I found the most annoying thing about being able to log into any computer you like is the fact that windows took its sweet time loading up your desktop if you never logged in to that PC before. Where I worked it just gave you a blank desktop and didn't bring what you had from another desktop with it so I would have to get all my shortcuts and set them up myself. Something tells me it isn't supposed to work that way. That's how Windows is "supposed to work" actually. They design it that way to get fast metrics on other parts of the process. It doesn't have to be that way, even with Windows. This is caused mostly by having users handled by Active Directory and having non-local profiles. This can be handy, but it has to set up a new user on the machine at the time that they log in for the first time and it needs to figure out what to do and often bring settings or files from somewhere remotely. There are plenty of ways to speed it up, but since it only happens under those conditions, most places ignore it.

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.

@mary said in An Overview of Windows 7 - CompTIA A+ 220-1002 Prof Messer: I watched it. I used that OS, seems outdated material. Windows 7 is the desktop version of Server 2008 R2 which came out in 2010. So just about a full decade old now!

@mary said in Troubleshooting Hard Drives - CompTIA A+ 220-1001 Prof Messer: When would it be a good idea to use a RAID 0? If you are always faced with total failure, what's the point? When the data doesn't matter, but speed does. It used to be popular with video game systems, for example, where load time mattered a lot, but it was easy to install again should the data be lost. RAID 0 is common in caching systems where data needs to be stored temporarily, but never matters. Basically, anytime that you'd be okay using just a single disk, you might be okay using RAID 0. If you think about it, if you have only a single disk and anything fails, all is lost. That's how your desktop is, for example. So if you are already okay with that risk, you might be okay with double the risk but twice the speed and capacity, too. It's for "ephemeral" storage.

@scottalanmiller As one of the tinfoil hat wearers around here, even I don't thing MAC filtering is anything other than headache and time sync.

But cloud itself is just an architecture. So you can do cloud for free. And things like Linux on cloud require no licensing.

@mary said in Cloud Models - CompTIA A+ 220-1001 Prof Messer: @scottalanmiller so cloud is a buzzword? Cloud is "the" buzzword. But thats separate. Cloud is a very real thing. Just not a thing requiring special hardware.
