AWS Advanced Networking
I recently completed the AWS Advanced Networking Specialism which is focused on core networking principles and the implementation of them on AWS. Here are my notes and also my mega tip for all AWS exams.
For my preparation and training I used and did the following:
“There is no compression algorithm for experience” but training helps.
Your going to have to know for this certification:
Now I always prepare for getting questions I don’t know or even getting some wrong, we are all human and you need to make sure you complete the exam. So here is how I deal with them. If I have a complete blank (the ones I just don’t know), then I take a guess, don’t waste time or worry about it. Any hard or unsure ones that I know will take time I have a quick stab at them, “Flag for review”, and then move on. If I have any time left later I will have a better crack at it.
Also be advised that some questions could be trial questions (you get about 5 per exam that are new questions your not marked on). But you won’t know if they are trail ones or not. So I am not saying they where or are but I did get some questions a little outside of the normal. They where:
In exam centres where you take your exam you can ask for and use a wipeboard and a pen for working outs and notes. For online proctoring and if you use Pearson VUE online then there is online whiteboard feature, a little basic like MS paint but good enough. To use this whiteboard option, then it is located on the top bar next to “chat” with moderator. All handy.
So given I can’t do subnet maths in my head and I got hit with two or three questions in first few minutes. Therefore I decided to crack open the online whiteboard and typed out the following table:
| YYYY.YYYY.YYYY.XXXX | ||
| 32 | 1 | Remember the first 4, plus boardcast cannot be used |
| 31 | 2 | |
| 30 | 4 | Also don’t forget VPCs and Subnets can be only /28. However for security groups, routes and NCL you can use them for non VPC addresses |
| 29 | 8 | |
| 28 | 16 | |
| 27 | 32 | |
| 26 | 64 | |
| 25 | 128 | |
| 24 | 256 | |
| YYYY.YYYY.XXXX.ZZZZ | ||
| 23 | 512 | |
| 22 | 1024 | |
| 21 | 2048 | |
| 20 | 4096 | |
| 19 | 8192 | |
| 18 | 16384 | |
| 17 | 32768 | |
| 16 | 65536 | Remember /16 is the max you can have for VPC or Subnet. However you can use ones up to /8 for security groups, NCL or routes for non VPC addresses |
For rest of the exam I was able to answer questions requiring subnet maths quickly and my head hurt a lot less. You can do the same tip

Enjoy and if doing this certification good luck
