How I passed my AWS exam
I passed my exam, you can too. The grade you need to pass is not known, and changes per exam and region taken. You should aim for a minimum of 70%.
This is the easiest of the associate level exams, but that is not to say that everyone will pass. Its a lot of material, and you will need time for it to soak in. You can do it!
As an introduction, lets find out what it means to be stateless and stateful protocol. Then lets dive into how using cookies helps us maintain a server-side session, and finally lets talk about security.
Originally HTTP began as a stateless protocol, which will not assume any special meaning between requests even if they originate from the same socket. While this is great for serving content, it only offers a generic user experience as the server is unable to distinguish between users natively.
With stateful protocol, the user state is persisted between requests so the server will be able to build context. For example, server would then be able to answer: Who are they? Are they authenticated? What items do they have in their chart? In constrast, a stateless protocol would handle each request as if it had seen it for the first time.
