Re: Scenario training!
Re: Scenario training! Good afternoon all,I'm back with my answer to my question, plus the answer to TheCheeseWheel's question. I'll also put another question at the end for you all. But first...A repeat of the question to refresh your memory.Marie arrives to the office on Monday morning and boots up her windows 10 computer, only to realize that she can't connect to even the network in the office.Opening up the command prompt, she runs the ipconfig command. She looks at her Ethernet adapter and sees her IPV4 address is 169.254.0.1, a private IP address.Marie knows that she had a valid connection to the network the previous work day. She is also sure nothing drastic has changed in her system.What is the problem here?A. Dhcp.B. Malware.C. Firewall.D. dns.The answer? . . . . . . . . . . . . . . . . The answer is A, DHCP.The reason's simple. When a computer first boots, it broadcasts a message looking for any DHCP servers on the network. Any DHCP servers listening on the network will hear this request, and will send out offers. The computer then requests one from one of the DHCP serversThe last step in the process is acknowledgement. The DHCP server will acknowledge said request from the computer.This goes to plan in most instances where a DHCP server is found and no static IP address is defined. If, however, we're using DHCP and no DHCP server can be found, the computer goes into the APIPA addressing zone.As for the cheese wheel's question, I'm going with driver, and ruling out the nic itself, since restarting the computer causes it to work normally and reconnect to the wireless network.Funnily enough, I actually had this issue myself on a couple laptops. One did end up having a faulty nic, needing me to purchase an external one.Hmm... Question to stump people with... let's see. Think... think... thinky thinky think away... think... away... aha!Joseph gets a call to a small business in town. A year ago, the business set up an array of drives in a raid 5 configuration.Recently, the business has begun experiencing degraded performance when accessing the storage array.What should Joseph check for after gathering details about the problem?A. High disk fragmentation.B. Malware on client computers.C. A secondary power supply.D. A failing drive.Bye for now, see ya all next Sunday!

Re: Scenario training!
Re: Scenario training! Op: Its definitely DHCP. That particular IP address is never assigned by a DHCP server but is used by Windows (and perhaps other OSes though I've never heard of Linux or MacOS using that IP address) when it can't acquire a DHCP address for some reason.GCW: its not a corrupt driver because I suspect a corrupt driver wouldn't load or would crash the system at random. Its more likely that the NIC is damaged or is old. It could be a driver issue, but I imagine that that would be the first thing someone who was trying to resolve this problem would check. If the problem vanished after a driver update, then it was most likely a buggy driver (e.g.: the driver was mismanaging the hardware), but if the problem persists after updating all drivers, its a hardware problem. It could still be a driver issue after updating drivers but that's very unlikely.

Re: Scenario training!
Re: Scenario training! As for the cheese wheel, I think it could be a bad network card. A friend of mine's laptop did that a while back and replacing the card fixed the problem. As for the first one it could either be Malware or DHCP issues.

Re: Scenario training! @4, could it be mal ware?because why would it work fine when you try to see what the issue is, but the worker tells you the internet keeps on disconnecting?I think it could also be incompattible network drivers causing the issuue here?Lastly, cMy last answer is that i think it is a broken internet card...

Re: Scenario training!
Re: Scenario training! Hello,@The Cheese Wheel, it can go either way. I'll throw in a question or two here and there, and you guys can also throe questions at me.To answer your question, I feel like it's a potential combination of 1 or both of these issues, corrupted wireless adapter driver, and or wireless adapter power settings, the former being way more likely to be causing issues than the latter.As for a clue to my question, the range set forth here is called APIPA, or automatic private IP addressing.I'll be back Sunday!Best,Omar, and a helicopter, that's just been circling randomly for the last 40 minutes.

Re: Scenario training! I like this idea, though I don't know if the goal is for us to test you or for you to test us. Now down to the point.First of all, I think this is a trick question because no way in hell would Marie be messing about in the command prompt unless she worked in IT. Even if she wanted to, it would probably be blocked. If she worked in IT, she'd already know what to do, but provided this isn't a trick question...I don't have an answer, but I'll try to work backwards and eliminate choices. I can't rule out B, because it could always be malware, though I'd put the scan off because I feel there are likelier candidates. If it were a DNS issue, that would be simple to rule out. All she would need to do is ask a coworker if she could look at their internal IP address and try to ping it from her machine. If it worked, no DNS issue. It could very well be a firewall issue - though my experience with firewalls is very limited so I wouldn't really know where to start with that. I doubt it would be a DHCP issue because I don't think you'll find they use that in corporate settings. I could be wrong, but it makes just as much sense that internal IP addresses remain static like their external ones do.Now for my question. This will be a write-in, no multiple choice because I'm curious what you come up with.Amy brings her work laptop into the IT department because it disconnects from WiFi seemingly at random. When this happens, the only thing that fixes it is to restart the machine. It's running Windows 10 1903, and apart from this issue, everything else seems fine with the machine. She is issued a new laptop while you work on this one. After putting it through it's paces, you notice that it will sometimes last days worth of seemingly normal use before disconnecting and refusing to reconnect. However, sometimes it's only a matter of hours. What is the issue likely to be?

Scenario training!
Scenario training! Good afternoon all,So with a few new IT certifications (with hopefully more to come) and at least 300 hours of training under my belt, I'm ready to put these skills to the test in ways very little test-prep materials can.So my request is this. Think of a question, and make it scenario based. I'll provide you an example down below, and let's see how many of you can get it right.I'll come back at the end of every week (if the circumstances allow) to spend a few minutes in this topic and answer some questions and potentially come up with some more questions.That being said, you can post issues your having with your own machine or equipment as well. I'll try and run through with you and see if I'm capable of helping you resolve it.You don't have to make these multiple choice either like this first one is, for added difficulty.So here's my first question.Marie arrives to the office on Monday morning and boots up her windows 10 computer, only to realize that she can't connect to even the network in the office.Opening up the command prompt, she runs the ipconfig command. She looks at her Ethernet adapter and sees her IPV4 address is 169.254.0.1, a private IP address.Marie knows that she had a valid connection to the network the previous work day. She is also sure nothing drastic has changed in her system.What is the problem here?A. Dhcp.B. Malware.C. Firewall.D. dns.Good luck!
