Answers to the Assessment Test
1. B. The Monitor section defines the monitor options and settings but doesn't combine it with the video card, so option A is incorrect. The Modeline line defines the available video modes in the Monitor section, but it doesn't define video cards, so option C is incorrect. Option D, the Device section, is also incorrect; it defines the video card but doesn't match it with a monitor on the system. Option E is incorrect because the Module section defines which X server modules (or drivers) are loaded but it doesn't match monitors and video cards. Option B, the Screen section, tells the X server about the combination of video cards and monitors that you're using, so it's the correct answer. For more information, see Chapter 6, “Configuring the X Window System, Localization, and Printing.”
2. A, C. Examining a process listing (obtained from ps) for signs of the super server is the most reliable way to determine which one is actually running, so option A is correct. The presence of the super server's configuration file or files (as in option C) is also a good diagnostic, although some older systems that have been upgraded may have both sets of configuration files. There is no standard superserver utility to report
