The new gig that I'll start on Monday began with a cold contact I received on LinkedIn. The one before that I think from a cold call from a recruiter.

As far as IT Manager, are you specifically wanting to manage people? I know my manager at my current gig is hands on with projects and really has to do minimal managing of us. I've also seen people with the title of "IT Manager" but they're a one-person-show in IT at said comapny, so there isn't anyone for them to actually manage.

what about the Windows Defender, I mean the antivirus and the firewall of Windows They go hand in hand right?

They go together as in they are both security components of the Windows operating system. But that's about the extent of it. They are both very good, they should both always be used, they are both for the purpose of security. But they are not actually associated other than in name.

Very useful tool, specially when computer gets freeze.

Very interesting, this tool we always use to check Windows system configuration.

Most of these tools I have used at least once doing support on computers.

Useful tools for networking!

taking a few mins to watch this!

@brianwinkelmann said in Microsoft Command Line Tools - CompTIA A+ 220-1002 Prof Messer:

Very Very Interesting, but the most important, this Command Line Tools are useful specially when you work remotely.

Or to be ready for when you suddenly half to!

Although they make you more efficient all of the time.

@ElvinNelson said in Writing a good CV:

It is more than enough to simply do it according to the already existing available samples and bring it to the form necessary specifically for your specific specialty. The above are also fine.

Sure, IF the form is any good. 99% are not. People who do "CV help" are never people who know or are in the industry. The CV assistance career path is one for failed English students desperate for work that no one can evaluate, there's no money in it. So if you get resources from anywhere except peers you are almost guaranteed to have something that's not very good, from a context of someone whose never done it before.

@scottalanmiller Imagine an IT Generalist bootcamp 😛

IT generalist is the bootcamp 😉

More like the war.

@brianwinkelmann said in Installing and Upgrading Windows - CompTIA A+ 220-1002 Prof Messer:

Interesting! I just wonder if it is possible for example to copy or move a complete installation of Windows to another disk just copying the files, is that possible? I mean like copy for example the whole C:\Windows folder to another folder on another disk D:\Windows and try to boot the Operative system? Well I don't know if my question is a bit dumb, sorry if it is.

No, you can't just copy the files. You have to image the system.

Very interesting, specially the Scott's reply.

@brianwinkelmann said in Windows in the Enterprise - CompTIA A+ 220-1002 Prof Messer:

Very Interesting, but I would like to check comments from other users about this features mentioned on the video, I mean all of them work properly and are useful at all? or there are another alternative like application or devices that can challenge with the features mentioned on the video? Well I just wonder.

Which features or apps do you mean?

@valentina said in Network Services - CompTIA A+ 220-1001 Prof Messer:

are proxy servers used for security purposes? do they have other functions?

Yes, very much so.

They are also very commonly used to allow a single IP address to be used for many services. The most common example... a single proxy server with a single (expensive) public IP address can handle requests for hundreds of thousands, or even millions, of websites. Behind the proxy server can be one or one million separate web servers each serving out applications or web sites or whatever and the proxy server can look at the incoming request and determine, based on the URL used, which server and port to send the request to behind itself.

Because of the above, they are often used for load balancing because they can send requests to different servers for the same application or site.

Proxy servers often have caches in them, too. So they quite often store simple, static information "at the edge" to deliver it faster while the application servers behind them do the heavy work for database requests and stuff.

Proxy servers are sometimes used to "hide" the true location of a server. Cloudflare famously does this so that attackers have no idea where a web site actually comes from, all they see is Cloudflare's proxies.

A proxy can also do things like handle SSL security so that web servers behind it (or other servers, proxy doesn't imply web) don't have to do that work, as well.

Hrm, I only have around 20 subdomains pointing to the same IP so far. If my home lab box was a little beefier I'd take this as a challenge. (Scott might as well be describing my home lab environment here.)

@brianwinkelmann said in An Overview of Windows 8 and 8.1 - CompTIA A+ 220-1002 Prof Messer:

Interesting, I didn't know Windows 8 has many features, but I don't think I can consider install Windows 8 in a Pentium 4 3.0 GHz with 3 GB RAM.

You should not consider ANY old OS, really ever. Outside of learning what support used to look like, which is effectively worthless, conceptually using an old OS is a bad idea. Windows 8, especially, is only one generation newer than Windows 7 which is already crazy old. Windows 8 is something like eleven versions old already!

@brianwinkelmann said in An Overview of Windows 7 - CompTIA A+ 220-1002 Prof Messer:

@scottalanmiller Ohh I see it is a good Idea to try LINUX!

Yes, very good time. Something light. Because there are so few resources.

Try this..

https://cdimage.debian.org/debian-cd/current/i386/iso-cd/debian-10.5.0-i386-netinst.iso

Very Interesting, I like Windows 10 xD

@brianwinkelmann said in Operating Systems Overview - CompTIA A+ 220-1002 Prof Messer:

So the disadvantage to choose LINUX is based on the drivers for different devices that you will use

That's incorrect. Linux has much broader driver support than Windows, and both have much broader support than MacOS. Support for more hardware is actually a huge benefit to Linux. That's why Linux and BSD are available on more platforms than any other OS.

@brianwinkelmann said in Troubleshooting Hard Drives - CompTIA A+ 220-1001 Prof Messer:

Very interesting, I remember I've heard that sometimes to fix a hard drive that is damaged you can put it inside of a freezer with bags of course and it can be fixed, is that true or is a myth or a lie? Sorry about foolish question. xD

Not a foolish question Brian. We have some customers who have done it. The drives (other than the brand new high capacity helium drives) are not air tight. They have a filter. So moisture can get it and start to corrode the platters.

If it has been in the freezer, we have to charge extra as it has to be cleaned with a special cleaning solvent that is about $400-500 per gallon.

Also it can cause a drive that may have been a logical or a physical non invasive recovery instantly into a clean room job (the most expensive option). So it's best to do nothing to fix it. Bring it to a quality data recovery company (like mine!) and they will have the best chance of recovering the data.

@Osvaldo said in Wireless Network Technologies - CompTIA A+ 220-1001 Prof Messer:

I wonder if there is a tool for radio hacking zigbee?

Many of the devices that use the protocol are never updated, therefor quite a large target for hacking.

The radio protocol itself I doubt is much use to "hack" (Any cheap software defined radio will be able to imitate a Zigbee device.)
