Summary

In this chapter, we have examined some of the key concepts that underlie the Solaris Operating Environment and the SunOS Operating System. From the kernel to the shell to different file system types, Solaris provides a number of sophisticated methods for managing systems and deploying applications in the enterprise.

Questions

1.	Which of the following best describes Solaris? Single user, single process Single user, multiprocess Multiuser, single process Multiuser, multiprocess
2.	What is the main responsibility of the kernel? Allocating system resources to complete assigned tasks Displaying graphics using X11 Managing applications Choosing the appropriate shell
3.	What sort of native file system does Solaris support? A flat file system, which begins with a C:\ directory A hierarchical file system, which begins with a root directory A flat file system, which begins with a root directory A hierarchical file system, which begins with a C:\ directory
4.	How are hardware devices logically represented on Solaris hosts? As special files As database entries As device plug-ins On the Control Panel
5.	How are processes distinguished in Solaris? By process names By command names By process IDs By session variables
6.	Which of the following file systems is not supported by Solaris? High Sierra Joliet UFS MS-DOS
7.	Which of the following subnets matches with a class B network? 255.0.0.0 255.255.0.0 0.255.255.255 255.255.255.255
8.	What might the file /etc/hostname.hme0 contain (choose two only)? The hostname of interface hme0 The IP address of interface hme0 The netmask of interface hme0 The ethernet address of interface hme0
9.	What video card bus types are supported by Solaris Intel? ISA AGP PCI All of the above
10.	What system architecture is recommended for running a Solaris 9 system on SPARC? Sun-4 Sun-3 Sun-5 Sun-60
