UFS quotas enable system administrators to control the size of file systems. Quotas limit the amount of disk space and the number of inodes, which roughly corresponds to the number of files, that individual users can acquire. For this reason, quotas are especially useful on the file systems where user home directories reside. As a rule, the public and /tmp file systems usually do not benefit significantly by establishing quotas.

Note: The cp command copies files and directories.

Oracle Solaris provides predefined rights profiles. These profiles, listed in the /etc/security/prof_attr, can be assigned by the root role to any account. The root role is assigned all privileges and all authorizations, so can perform all tasks, just as root can when root is a user.

To perform administrative functions, you open a terminal and switch the user to root. In that terminal, you can then perform all administrative functions.

$ su - root Password: Type root password # When you exit the shell, root capabilities are no longer in effect.

Correct Answer: C

This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to use either SMTP or SNMP. Normally, you would only select SNMP if you already have SNMP configured for some other reason.

By default, SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring, you can configure additional traps for other state transitions.

1. Become an administrator or assume a role that includes the Service Management rights profile.

2. Set notification parameters.

Example: The following command creates a notification that sends email when transactions go into the maintenance state # /usr/sbin/svccfg setnotify -g maintenance mailto:[email protected]

You can enable this property as follows: # zfs set dedup=on tank/home
