First the full backup must be restored. This would be the Sunday backup.

Then the last incremental backup must be restored. This would be the Wednesday backup.

Before restoring the Wednesday incremental file system snapshot, the most recent snapshot must first be rolled back.

By exclusion D) would be best answer even though it is incomplete.

This procedure captures in a syslog file all failed login attempts.

1. Set up the /etc/default/login file with the desired values for SYSLOG and SYSLOG_FAILED_LOGINS

Edit the /etc/default/login file to change the entry. Make sure that SYSLOG=YES is uncommented.

2. Create a file with the correct permissions to hold the logging information.

Create the authlog file in the /var/adm directory.

3. Edit the syslog.conf file to log failed password attempts.

Send the failures to the authlog file.

SVC.CONFIGD is the repository daemon responsible for maintaining /etc/svc/repository.db. The repository.db must come clean during this integrity check otherwise it is a "no go" for usual boot sequence to run level 3. The repository may get corrupted due to various hardware issues, software bugs, disk write failures, etc.

Note: When svc.configd(1M), the Solaris Repository Daemon, is started, it does an integrity check of the smf(5) repository, stored in /etc/svc/repository.db. This integrity check can fail due to a disk failure, the database file being corrupted either due to a hardware bug, a software bug, or an accidental overwrite. If the integrity check fails, svc.configd will write a message to the console.

Part of the job of cleaning up heavily loaded file systems involves locating and removing files that have not been used recently. You can locate unused files by using the ls or find commands.

Other ways to conserve disk space include emptying temporary directories such as the directories located in /var/tmp or /var/spool, and deleting core and crash dump files.

Note: Core files are generated when a process or application terminates abnormally. Core files are managed with the coreadm command.

For example, you can use the coreadm command to configure a system so that all process core files are placed in a single system directory. This means it is easier to track problems by examining the core files in a specific directory whenever a process or daemon terminates abnormally.

By default, the passwd command assumes a minimum length of six characters. You can use the PASSLENGTH default in the /etc/defaults/passwd files to change that by setting the minimum number of characters that a user's password must contain to some other number.
