Error 404 on the link of AWS CLF-01

On clicking the link of " A summary of what you need to know for the exam can be found [here](https://codingshell.com/aws-cloud-practitioner)" this link is giving error 404.
I request repo keepers to fix this

Search the repository for the text “A summary of what you need to know for the exam can be found” and inspect the surrounding AWS CLF-01 documentation entry. Check the current destination and identify a valid replacement, then verify the updated link no longer returns 404.
