Members of a team already have experience using Red Hat Enterprise Linux. For a small hobby project, the team wants to set up a Linux server without paying for a subscription. Which of the following Linux distributions allows the team members to apply as much of their Red Hat Enterprise Linux knowledge as possible?
CentOS is the correct choice because it is derived from the freely available source code of Red Hat Enterprise Linux (RHEL) and maintains binary compatibility with its upstream source, making it the best option for leveraging the team's existing RHEL knowledge.
