Hello Daniel
The content that is covered in the CCNA 201-300 can be found on the following course page:
You may find that some of these lessons are also under the older ICND1 and ICND2 course pages and categories because the content was in those courses as well. However, the official topics are found in the course site I sent above.
To see the official list of covered material, take a look at Cisco’s official list at the following link:
https://learningnetwork.cisco.com/s/ccna-exam-topics
You will see that this aligns well with the course page I shared above.
I hope this has been helpful!
