ilkhan posted:If your IP is the house address that tells mail where to go, a port is the name portion or apartment/suite code of a letter, telling it specifically who it's address to. Various services listen on specific ports for incoming communication. And if it’s closed it’s like when a business executive tells their secretary they’re not here for someone they don’t want to talk to? Ok thank you that makes sense.

A port is generally closed unless it is specifically opened by an application. For example, if SSH is turned off on a device, you would expect port 22 to be closed, and if it is turned on, you would expect port 22 to be open.

In case you want some irony poisoning https://www.theregister.com/2022/09/02/telegram_court_ip/ A exam cram maker wants telegram to hand out the ips of people copying his exam copies, while having his name in the clear for prometric/pearson to sue his rear end.

I'm working my way through the Hardware domain on the A+ right now. So far I've got max cable lengths, DDR4 transfer speeds in Mb/s, and port numbers. Are there any other dumb things I just have to memorize that I've missed so far? What ones beyond the ram portion of the hardware domain do I need to look out for and start drilling when i get to them?

I've been asked to do AZ-104 and then AZ-105, with a goal of having the AZ-105 in 6-8 months. How much am I going to hate my life?

Good news is that there isn’t an az-105 so that’ll save you time. Now if you meant the az-305 then that’s a major red flag from whoever is requesting this out of you.

Motherboard sizes, all the USB types, maybe all the monitor connections as well. The cable lengths and port numbers will show up in other tests as well so they're probably worth getting good at. I'm taking a break from studying the CCNA and every cert test has felt the same in that there's an endless amount of things to know.

I'm studying the AZ-305/700/80x for purely educational reasons (mostly SD-WAN concepts), but the CCNA for "for real" im broke as gently caress and cannot afford Boson, only the two official Wendell Odom books and some free Packet Tracer labs I feel like Cisco Modeling Labs would be more preferable since in already going to study for higher level cisco certs but a second opinion never hurts BornAPoorBlkChild fucked around with this message at 06:49 on Sep 20, 2022 |

I used the Lammle books for the previous incarnation of the CCNA and it was great. I would think the new one would be good but have no first-hand experience with it.

Took the AWS Developer exam today. It's been awhile and I forgot how much it sucks you don't get the result straight away. I'm also an idiot for planning it on a Friday which probably means waiting over the weekend to get the result.

Signed up for a VCP class before the whole Broadcom snafoo. Had to take the VCTA-DCV apparently for my class to be recognized. Then knocked out the VCP-DCV. Strangely enough I scored higher on the VCP exam. VCTA = 447 VCP = 484 Now to find more crap to bang out. Maybe some Juniper/Cisco and pepper in some ~cloud~

Didn't have to wait over the weekend. Passed with a score of 834 (720 needed) so had a fair margin. On to the next one.

Hughmoris posted:Congrats! If you have the SAA, how did the Developer exam compare to it? Developer is supposed to be the easiest one of the Associate exams. For me this one felt more difficult even though I’ve got a few years more (hands on) experience with AWS now then when I took the SAA. My experience is more on the services covered for the SAA though. Not sure why it felt harder but it might be because I don’t try to just study for the cert but really want to understand the matter on an in depth level. The core services everyone uses were a piece of cake, just like several others I work with regularly. But the exam is pretty wide when it comes to the amount of services to cover and memorizing all the details, limits and default values takes time and effort. Maybe I’m just overpreparing.

What’s the difference between WPA2 and AES? I know they work together and are the two types that are least vulnerable to attack but why aren’t they a single protocol? The book I’m using doesn’t really say why they’re different so I assume it’s not important for the a+ (or beyond it) but I’m curious

The book I’m using doesn’t really say why they’re different so I assume it’s not important for the a+ (or beyond it) but I’m curious AES is an encryption standard, it can be used all sorts of places, not just for wireless networks. AES can be used in disk encryption, SSL certificates, software encryption, etc. WPA2 or 802.11i defines the protocol standard for WPA2. If you want your wireless device to be WPA2 compliant it lays out the standards for the protocol so your device can be compliant. AES encryption is part of that suite of protocols and rules for lack of a better term. Think of WPA2 as being a framework of rules for all the stuff going on inside the wireless transmission/network like key exchanges, packet frames, stuff like that. Hope that helps, feel free to ask for more detail, I don't want to get too in the weeds about this stuff. The Wiki page for WPA2/802.11i gets into it as well.

Passed the CCNA. Much like PenTest+ I was pretty sure I wasn't going to pass. I've felt under prepared for pretty much every cert test I've taken and somehow keep scraping by with passing scores. My only question now is how easy/difficult will it be to break back into IT. I did nearly two years of help desk and for the last month went back to calibrating stuff and things cause of a move.
