Self Test


The following questions will help you measure your understanding of the material presented in this chapter. As no multiple choice questions appear on the Red Hat exams, no multiple choice questions appear in this book. These questions exclusively test your understanding of the chapter. Getting results, not memorizing trivia, is what counts on the Red Hat exams. There may be more than one answer to many of these questions.

The names of package groups within the Server group that install servers are DNS Name Server, FTP Server, Legacy Network Server, Mail Server, MySQL Database, Network Servers, News Server, PostgreSQL Database, Printing Support, Web Server, and Windows File Server. While there's no requirement to memorize these names, if you've installed RHEL a few times, you should be quite familiar with at least the names of a few of these groups.

10. 

If you don't see the GUI First Boot process after RHEL reboots for the first time, you probably haven't installed the GUI. (It's also possible that you have a configuration problem, such as a full partition associated with /home, that prevents the GUI from booting normally.)
