but when the questions are "you need 4 networks which subnet mask would you use on this ip: 10.1.1.25"

That's gibberish. There's no way to know based on what is stated.

I probably missed the actual question.. but questions similar to that confuse me.

It's all math and high school style word problems. It's all about "to meet the requirements", what options would you choose so that the sizes are correct.

@pete-s ah ok, I don't remember it happening as much though.

You should never over lap channels that causes co-channel interference. If you have to then as stated above the AP's that are farthest physically apart should use the same channel.
Also, I would turn off 2.4GHz unless you NEED IT and even then you probably don't NEED IT on all 4 AP's. Try just on 2 AP's to reduce interference and see what happens. Many cases in our offices I have either completely turned off 2.4 or I have it on only 1 AP and absolutely no complaints about wifi since I did that.

Okay, what's the point in interviewing someone if you're not considering hiring them or offering a job? to see if they're a good fit, right?

@flaxking said in Azure or 0365?:

I'd say there's probably more roles out there to move up into. Companies may be using Microsoft 365, but could be using other providers for their cloud infrastructure. They might also expect their cloud engineers to know multiple platforms. I had experience creating highly available environments on-premise before breaking into Azure.

This is a good point. The number of M365 jobs out there probably outnumbers Azure jobs. And the M365 jobs typically need just one skill, whereas a typical Azure job will require many. And one is a logical step from helpdesk, and one is a total focus change.

Example: I have an IPv4 network, and you have an IPv4 network, and we want to talk to each other. But there's no IPv4 network between us. We need to tunnel our networks somehow through whatever is between us so that we can network to each other. That in between network could be anything, NetBEUI, IPX/SPX, IPv6, whatever. As long as we tunnel through it, our IPv4 networks can see each other (but not the network inbetween).

What is the best way to secure the most vulnerable attack vector for a network?

Choices:

A] Remove unneeded services running on the servers
B] Provide end-user awareness training for office staff
C] Update all antivirus definitions on workstations and servers
D] Use biometrics and SSO for authentication

Hey First Question - Thanks Scott

My first instinct D]Use biometrics and SSO for Authentication

The key words in the question is "most vulnerable attack vector" so IMHO, D] would incorrect.

Well People would be the most vulnerable

so B?

Correct, B. @scottalanmiller will have to confirm though.

I thought that too, but then I thought that was too easy and that he probably was meaning something else .

The test SHOULD be too easy. If you really know the material, and are paying attention to the reading (because the questions are designed to not let you skim them), it should feel pretty obvious a lot of the time.

Syncthing on the reports directory?

Definitely an option.

Hey I knew that one! lol I ran into that in the past, I just didn't know what telnet was used for.

Sort of... everything, lol.

well, I see that now, I watched the video then did my own research for it.

@Pete-S only Cisco gear that label along with the sonic wall was more as documentation for myself.

University schools that has a surplus have some useful equipment for lab use.

I’m doing that with a friend and his kid- it’s older UBNT and other gear- but it give a 10yo something to start with.

What have they retired? That would be the only thing that matters on using older machine - the possibility that some newer commands aren't there.

I will be upgrading my UniFi hardware. So I have two APs that I am replacing. the Controller is a VM still.

I also had a project build of a Stand alone Point to Point wireless network for our Club. It's two UBNT M5 units and two EnGenius EAP9550 units One running DHCP, and the other a slave. The idea was that when we did a contest (Field Day) we could be across a 400yard area, and it would be nice to have internet / network for file sharing and such. I built it, it worked - and no one was interested in it. So - I'll be giving it all to him for his kid to learn on - tear up - etc....

@manxam said in Collision Domain - In POS:

I can't recall ever seeing a switch "back in the day" that didn't have ASICs. There are a few newer switches that do, in fact, use CPU rather than ASICs, but they're built using MUCH faster CPUs than what are included in most -- if not all -- routers.

Early days, the ASICs didn't even exist yet. It wasn't a choice, it was all that there was to use software. Then the ASICs came along and obviously dominated. But yes, it always requires throwing more hardware at it.

How far back are we going here? My first experience with a switch was with Alantec/FORE ATMs (circa early 91/2). These had a RISC SCP processor to run the OS/management functions and custom ASICs for switching. After that, in the more mainstream, came Kalpana and then Cisco. To the best of my knowledge, there were no switches available prior to thicknet (first commercial ethernet).

I'd love more information if you have it available. I love the history of tech.

Not that far back, still 90s, but a lot of switches were all software in the middling to later 90s as the ASICs weren't broadly available.

But even the very, very first ASICs were / are always based on working software prototypes.

I've never seen a thicknet switch, what a freaking mess that must be.

Be able to lock it down so he can only use the School Apps etc ?

If you use Chromebook tablets, there are no apps conceptually by default. And there are regular user accounts.

@WrCombs said in Huge Mistake:

The software I installed was a free Trial
it wont let me actually recover anything until I pay for it...

:man_facepalming_light_skin_tone:

Wanting to use only Free fully functional recovery software means your data is not valuable to you.

I have recently tried the following data recovery tools:
Piriform Recuva
Cgsecurity Testdisk

On a formatted partition with good results. But some files were corrupted or lost.

There are many more free programs most are a cut down version of a commercial package.
A few recover a limited number of files for free or show you what could be recovered if you Pay for a license.

Based on my experience, though those tools are paid, they are more professional and find more good results than free ones.

I would recommend to you:
iBoysoft Data Recovery
EaseUS
Disk Drill

Please note that If you look for an unformat option if you have not written to the formatted partition since it happened (although windows will write to the drive anyway ). Because how successful they will depend on how much has been written to the drive since formatting. Therefore, you'd better use another hard disk eg USB, SATA, or over a network to a hard drive to recover the data.

This post will be helpful: https://iboysoft.com/data-recovery/recover-data-from-formatted-hard-drive.html

Moreover, depending on the value of data ask for professional help or carry on recovery yourself.

Since you are connected to the printer via USB. Disable plug and play. And then delete all those extra printers.

@WrCombs said in Unrouted Wireless Network setup:

I'm sure there's some degree that it's different, because Tablets memory and Storage is no where close to a Desktop PC. but it the OS runs the exact same.

The fastest computer in my house is a tablet. Intel i7 9th gen, 16GB RAM, NVMe storage. Way faster than any of our laptops or desktops.

Tablet is just a shape and while they can't contain the power of a giant gaming rig, they can do anything a laptop or normal business desktop can do. It's literally just the shape.

@WrCombs said in what is automation? How does it work?:

@Dashrender said in what is automation? How does it work?:

There are multiple ways to get automation. Simplest might be to write a script that copies files and execute that script using Task Scheduler (a windows service that allows you to execute tasks based upon a specific schedule).

Thanks - Got more information now:
I need to be able to automatically send a folder to compressed zip.
Then automate the import and publish.

The more information I get the more confused I become about all of this.

The first step to automating a task is defining how you would do it manually. Start there. That doesn't mean the automation will just copy that, but it helps to understand what you are doing today, before you figure out how to do it automatically tomorrow.

Do it here?
I mean, That's fine with me.

I would make a new thread about that specific task, and you could toss a link in here to that.

@WrCombs said in Unifi AP on unrouted Network - Issues:

How do you Export/Import Sites into new controllers ?

Never mind I figured it out.

I went into "site" settings , In the bottom left corner there was "export site" option.
Click on that, download the backup file,
create network on other Controller, then import site.
You can then (if you have a domain set up) migrate the AP to that Controller.

I didn't have this issue; I installed and it's working properly, can view, and edit the AP .

@Pete-S said in Need to Install SQL Server Management Studio:

I'm pretty sure you can install the management studio on any computer. Doesn't have to be on the computer that actually has the SQL server installed.

That's correct. SQL Studio requires Windows, but SQL Server does not. So we sometimes do that, as well.

Yes or a 64-bit Windows 10 with a new version of Management Studio, managing an older 32-bit Windows 7 SQL Server install :)
