Let's do ah two or three sample test questions on hard drives and these are representative of what you could see on the exam and let's work through these. First question. What is the largest partition possible using the FAT file system? And I've reminded you in the question here that FAT16 is the same as FAT. Now, is the answer 32 gigabytes, 32 megabytes, 32 terabytes, 64 gigabytes? Well, the correct answer is 32 megabytes and the only thing I can tell you is that you just need to remember this. Thirty-two megabytes, just remember this seems kind of small. It wasn't a big deal at the time, but it'd be considerably limiting now. But um, just remember 32 megabytes was the max for the FAT file system and that's one that's just rote memorization just knowing that answer is going to be the only way to get that one right. Now, which of the following best describes a cluster? A spanned volume of at least four disks; that's not a cluster. And if you remember that's ah, that has to do in dynamic disk types. Ah, data that's unreadable? Eh, data that's unreadable could exist in a cluster but that's not what makes it a cluster. Contiguous sectors, and this is most likely going to be the correct answer, or a bootable partition, and a bootable partition is ah, an active partition, so that's not necessarily a cluster. So the correct answer is contiguous sectors, and if you remember in the video where we talked about hard drives, contiguous sectors on a hard drive that are ah managed together as a unit are called clusters and so the hard drive is divided into sectors and then the sectors are grouped into clusters for maintenance by the ah file system. So, contiguous sectors. Now, which of the following RAID configurations do not protect data from loss? And here's your choices: RAID zero, RAID one, RAID five, or all of the above. Now again, this is another one of those examples where you're just going to have to know your RAID configurations to be able to get this right. Now let's go through them and this is another thing, use sample tests and you can find some out on the Internet for free, ah, it's well worth your money to go invest in some of these. I'll talk about them at the close of the course, ah and go through these test questions. Because for example in this one I can learn a lot just by figuring out the answer to this question. For example, ah let's, let's start at the top. RAID zero, if you remember, was disk striping; this is where we spread the information across multiple disks, but if we lose one of the disks our data is gone, so it does not protect data from loss, and that is probably the correct answer. Sure enough, it is, but then RAID one, if you remember was disk mirroring, and then using two disk controllers makes RAID one called Disk Duplexing, and that does protect data from loss. RAID five protects data from loss because if you remember it stripes it across multiple disks and maintains parity information so it can rebuild a missing disk should one fail. And so, RAID one and five do protect from data loss, RAID zero is the fastest way to put data on a disk and get it off the disk, however it does not protect it from data loss. Now, on, as you look at some of these sample questions and if you invest in some of these ah sample questions, products that are sold, keep in mind you learn a lot from these and when you look at these, don't just choose the right question and go on, make sure you go through mentally, Now wait a minute, what is RAID one? And if you're not sure, go do some research on it. What is RAID five? And if you're positive go do some research because what you're trying to do here in taking this test is prove, not only that you know the facts but you know how the facts all work together in a computer system ah to make the thing function properly and that is what we're really trying to measure with A Plus 2006 is your competence overall with the computer, not just your knowledge, okay. A lot of people could tell you generally the ingredients, what has to happen to make the conditions right for a nuclear explosion, however, not many people can actually, you know cause a nuclear explosion to happen, okay, and that's a good thing, I know, but ah, still, so a lot of people can, can talk about the various pieces and parts but they can't put them together and make things happen and that's what we're trying to do here with the A Plus is certify that not only do you know some of the facts about a computer, but you know how they interact together to make a computer do what a computer does. So, three sample test questions here. I hope this helps kind of get you acclimated to what you're going to see when you actually go sit this exam.
