I took the Acquia Back End Specialist - Drupal 9 Certification exam a few days back and passed it with 80% correct answers. Writing this blog post to share about my experience and preparation tips for anyone who is planning to appear for the certification exam.
Almost all the questions are scenarios based and require actual development experience in Drupal 9. So just knowing the concepts may not be very helpful for this exam, but you should also understand how these concepts can be utilised for developing a better application.
The exam strictly follows the pattern mentioned on the official website and all the questions fall under one of the topics mentioned in the domains. So make sure, you have checked this link in case the domains or respective weightages have been updated.
The most important topics for the exam are: Cache API, Form API, Entity API, Basic-to-Advance level development skills in HTML, CSS, jQuery and PHP, Composer, Git, Routing, Controllers, Security, Performance and Community Contribution skills.
Here are all the links of official documentations or blogs which you definitely read before attempting the exam:
Best of luck!!
