Chapter 2 - Installing Solaris 10 Software + Sample Test

A. The pkgrm command is used to uninstall (remove) packages.

B is incorrect because you should never use the rm -r command to uninstall a package; uninstalling the package is not identical with just removing the package files. C is incorrect because there is no uninstall file to uninstall the packages, and D is incorrect because the patchrm command is used to uninstall the patches and not the packages.

/etc/passwd contains the new account information, and /etc/shadow contains password information for the new account.

A process with priority 10 is not lower priority than a process with priority 20. In priority-based scheduling, a higher priority value indicates a higher priority level. Therefore, a process with priority 20 is higher priority than a process with priority 10.

The command "volcheck" is used to inform the Volume Manager that a floppy disk has been inserted into the floppy drive. This command triggers the Volume Manager to check for any new volumes or disks that have been added to the system. It allows the system to recognize and access the contents of the floppy disk.

C. The pkgtrans command is used to convert a package from one format to another,

A and B are incorrect because pkgformat and pkgmake are not commands in Solaris 10. D is incorrect because the pkgadd command is used either to install or to spool packages and not to transform their formats.

E. The developer software group contains the packages for the end user Solaris software group plus additional support for software development.

A, B, and C are incorrect because these groups do not include development tools. D is incorrect because this group contains software for the server functionality that is unnecessary for this workstation.

D. The pkgchk command can be used to check the accuracy of the installed packages and also to check the content of the spooled packages.

A is incorrect because the pkginfo command is used to list the package information and not to check the accuracy of the package installation. B is incorrect because the pkgask command is used to save the responses from the user for the pkgadd command in a file. C is incorrect because the correct command is pkgchk, not pkgcheck.

The correct answer is that server daemons are started at run-level 3, while client daemons are started at run-level 2. This means that the server daemons, which handle the file system sharing, are started at a higher run-level than the client daemons, which are responsible for accessing and using the shared file systems. This setup ensures that the server daemons are up and running before the client daemons start, allowing for a smooth and efficient NFS operation.

After creating a new concatenation metadevice, the command that must be run is "growfs /dev/md/rdsk/". This command is used to grow the file system on the metadevice and make it available for use.

If no options are specified, the default action is to perform a level 9 backup to the dump file /dev/rmt/0 (default tape device) , and update the dump record. Thus, the default options are '9uf /dev/rmt/0'

A. The minimum RAM requirement for installing or upgrading to Solaris 10 is 64MB.

B is incorrect because 256MB is the recommended RAM, not the minimum required; C is incorrect because 384MB is required only if you want to use installation GUI; and D is incorrect because 32MB is less than the minimum required.

A, C, and E. The WAN boot method is used to install Solaris over a wide area network (or Internet), the live upgrade method is used to upgrade the system to Solaris 10 while it's running, and certainly you can install Solaris 10 interactively by using the text installer or the GUI.

B and D are incorrect because you cannot install Solaris by using network cloning or UUCP.

"man passwd" with no options will display information about the passwd command, not the /etc/passwd file.

B. It is the -d option and not the -n option used with the patchadd command that will instruct not to back up the files to be patched.

A, C, and D are incorrect answers because they are the correct statements.

B and C. The pkgchk command can be used to verify the installation of a package and also to get the information about the packages in the spool directory.

A is incorrect because the purpose of the pkgchk command is not to detect the errors in the data of the package files. D is incorrect because pkgchk is not a version control utility.

"init s" will bring the system to single-user state, and the default run-level of the "shutdown" command is also single-user.

B, C, and D. A patch will not be installed if it is being made obsolete by an already installed patch, if it has the same base code but lower revision code than an already installed patch or if it depends on a patch that has not yet been installed.

A is incorrect because the patch to be installed does not have to be the latest version.

The swap partition can be activated explicitly by using the swap command. Additionally, the /sbin/swapadd command will read /etc/vfstab and activate any partition or file specified as a swap device.

The "-o ro" option is recommended for best performance, and the "-F nfs" is typically used, but the only required options are "-o backfstype" and "-o cachedir".

B and D. The six software groups in Solaris 10 are: reduced network support software group, core system support software group, end user Solaris software group, developer Solaris software group, entire Solaris software group, and entire plus OEM support.

A is incorrect because core system support is a software group, while core system support plus OEM is not. C is incorrect because the name for a software group is the developer software group and not the entire developer software group.
