Certificates:

RHCSA (Certified System Administrator)

An RHCSA is able to perform a number of tasks across IT environments — on-site and across clouds — as required in some of the world’s most demanding data centers with the deployment of Linux on multiple architectures. 

RHCE (Certified Engineer)

An RHCE is a sought-after credential for those professionals who previously certify as RHCSA. They can then opt to become an RHCE through the EX300, which tests to determine if individuals have the knowledge, skills, and abilities of a senior system administrator responsible for Red Hat® Enterprise Linux systems.
