Anyone got a quick snappy way to get mentally subnetting without paper down? It's basically my last barrier for the CCNA and I just can't internalize looking at a network range and mask and pulling out a host/subnet count.

That's a good video but I feel like people stress out too much thought into subnetting , especially for the exams. I've seen bootcamps that dedicate a whole day to the topic. You can memorize 2^n (2^n - 2 for host counts) ... or just remember /8, /16, /24 (which represent 255.0.0.0, 255.255.0.0, and 255.255.255.0), and repeatedly dividing 256 by 2. That's all you need to know. You have a 10.10.10.0 /27? That's 3 higher than 24. Divide 256 by 2 three times (128, 64, 32). Your network IDs are 10.10.10.0, 10.10.10.32. 10.10.10.64. 10.10.10.96, and so on until 10.10.10.224. Your useable host count is -2. So for a /27 (which is 32), you can have up to 30 hosts. The first one is the net ID, the last IP is the broadcast. So in the network 10.10.10.32 /27, your netID is 10.10.10.32, your useable host IPs are 10.10.10.33 - 10.10.10.62, your broadcast is 10.10.10.63. If you are given the subnet mask instead of CIDR notation, it's even easier. 10.20.30.0 255.255.255.128? Subtract the last non 255 from 256. 256-128 = 128. You have two subnets with network IDs of 10.20.30.0 and 10.20.30.128. Apply the same logic as above to determine useable hosts and broadcasts. (There's two exceptions to the useable IP range, /31 and /32. IOS-XE has supported the use of /31 for point to point links for a while now, despite that the -2 to calculate usable hosts suggests it can't be done. /32 can be used for loopback addresses.) edit- slight correction the quick host count only works for /24 and higher, anything lower you'll just have to multiple instead of divide. so /23 is 512 - 2, /22 is 1024 - 2, ect.

In my experience, you’ll have one of three types of subnetting questions on the test. The first is a picture of a network diagram with two hosts that can not communicate with each other. One of the four choices is “they are on different subnets” and after looking at the diagram again, you determine that it the correct answer. The second is a question asking which IPs are on the same subnet, typically in a “select multiple” format. This is all about knowing the useable host range. The third is asking you to take a network and divide it up into multiple subnets for a specific network/host count. Such as you are given 10.10.10.0 /24 and asked to divide it up so you have 7 useable networks with at least 29 available host IP. 25 will give you 2 subnets, /26 will give you 4, /27 will give you 8 (doubling as you go) with a useable range of 30 (as explained in the previous post).

You can make notes during the CCNA.

Does anyone have any experience with the online testing? I'm trying to get my A+ before the new version comes out, and all my local testing centers are closed for the entirety of Ramadan. Looking at a career change, and figured A+ and N+ would at least get my foot in the door.

I took the net+ online a couple months ago. A little before the scheduled time you check in on the app, they ask you to take a few pictures of the testing area, then you wait in a queue. They call you to test your microphone and camera. I had an issue where they couldn't hear me so they said to restart the app and they bumped me back to the front of the queue. It was a pretty painless process. The rules of what you can't do are pretty clearly defined. (no talking, no mouthing words, eyes glued to the screen) I think there was a way to take digital notes inside the app but I don't remember.

I passed! It was easier than I expected... Security+ felt harder to me. A couple of the performance questions were weird, notably one was an awkward "help desk" simulation that expected you to close out a ticket based on some pretty non-conclusive findings. Hot topics were: software development best practices, log analysis and incident response.

So I took the Cisco ENSDWI 300-415 (SD-WAN) exam and failed it of course. The weird thing is, I didn't get a simple grade number at the end like in previous Cisco tests I've taken. Instead it gave me a breakdown of the 6 different skill areas and and a percentage number for each. So I'm not sure how exactly the overall grade is scored I was thinking maybe they average the score from the 6 areas but I think that would only work if you got the same amount of questions for each? And if that is the case then drat you could fail after only getting a few of the questions wrong. Does anyone know how this works now?

It’s more like a primer for sales to memorize which services there are and what they do. Very little value for engineers but if your job pays for it you could take it as a warm up for the CSAA exam. It can easily be done in a week.

Hey folks - I received a request to update the OP with more current information, since a lot of this is out of date. I moved into ~management~ about 4 years ago and haven't been as focused on certs (other than some cloud-based stuff I'm currently working on), so I'd appreciate it if the community could provide the latest and greatest. Feel free to PM me and I'll update each section accordingly.

So many people also convert their GI Bill to Vocational Rehab, I didn't, but it seems like you get more if you do. Best of luck and holler at your schools VA office for test vouchers.

Devorum posted:Question: is going to school for IT worth it? I have the GI Bill burning a hole in my pocket, and am looking for a career change. Would I go for a CompSci degree, or is there something more suitable? I have a ton of veteran classmates in my comp sci program. If you have mostly free college available, and can afford the time to go, I think it can only help you. There's a lot of on-campus support for Veterans at my college, with networking (not CCNA) and counseling services specifically for them. I am not a veteran, but I went back to school as an adult. I started with a general IT degree and found it too development focused, so I moved to the Cybersecurity degree path, which is a mix of Networking (CCNA this time), Fundamentals of Programming, CompSci, and Infosec topics. I feel like it has gone a long way in my learning and knowledge, and I don't regret a minute of it. That said, it has been a long path. My career change took 4 years, a lot of work, and determination. It seems to be paying off with an upcoming Internship, but it took a lot of grinding. Wouldn't change it for the world, it's my biggest accomplishment in life, but if you are working full-time it can be brutal. Famethrowa fucked around with this message at 14:39 on Apr 27, 2022 |

Would I go for a CompSci degree, or is there something more suitable? Depends on what part of IT you want to get into. "IT" is very broad. CompSci is great if you want to be a software engineer/programmer, but a lot of the IT Infrastructure/Operational stuff like managing servers, networks, cloud is more like a skilled trade than something you need a CompSci degree for. Most computer science degrees focus on theory and programming, not the day to day IT management tasks. Also consider things like Project Management, Scrum/Agile training, things like that. I started out with the Microsoft training path at a community college 20 years ago and that worked for me. I'm a huge fan of community college programs when it comes to IT training. I'm not a huge fan of bootcamps, but they can work for some people. They don't suit my learning style really. Cloud and Information Security are the two hot markets right now. If you hold a TS clearance and can get a few security certifications you can pretty much write your own ticket. Same for project management.

I was the Cyber/Infosec rep for my squadron for a couple of years and while it's not nearly as involved as a dedicated CS job on the outside, I enjoyed what I experienced of it. Unfortunately, my Secret clearance lapsed a couple of years ago. I've been out for a few years, I'm just beyond tired of my current career field and need a change. I've been doing basic IT infrastructure and operation stuff most of my life as a side hustle, so it seems like a natural path to take. I'm taking my A+ tests soon, but I really don't want to let my GI Bill go to waste. Using it also gives me some breathing room between my current job and finding a new one.

I wouldn't waste the money on the A+ exams personally. Cyber/InfoSec is a pretty hot job market right now. I'd look into that sort of a degree field.
