the exam is built around solving real problems, and not as a test with many theoretical closed or open questions;
the ability to choose a Linux distribution for the exam from three options: CentOS, openSUSE or Ubuntu.
The cost of passing the exam and obtaining a certificate is 300 USD, anyone can get certified, but this requires knowledge of English.
