The advantage of core tiles is that they allow you an opportunity to examine the cause of problems, so that they can be resolved.
However, core files must be managed because they .

1. A. take up large amounts of disk space
2. B. make numerous entries into the /var/adm/wtmpx file
3. C. steal resources from the processor, slowing down system performance
4. D. fill up swap space; this will begin to slow the system due to swaps
5. E. fill up swap space; this will begin to slow the system due to paging

Correct Answer: A
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.

In a default standalone installation of Oracle Solaris 11, what is the default minimum length in characters of a user password, and where is the minimum password length defined?

1. A. Default minimum length is 8, and is defined in /etc/default/password.
2. B. Default minimum length is 6, and is defined in /etc/default/password.
3. C. Default minimum length is 8, and is defined in /etc/shadow.
4. D. Default minimum length is 6, and is defined in /etc/shadow.
5. E. Default minimum length is 8, and is defined in /usr/sadm/defadduser.
6. F. Default minimum length is 6, and is defined in /usr/sadm/defadduser.

Correct Answer: B
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.

Consider the following rule file for use with the Basic Audit Reporting Tool (BART).
CHECK all IGNORE dirmtime
/etc/security
/etc/notices IGNORE contents
/export/home
IGNORE mtime size contents
/var CHECK
You are using BART to detect inappropriate changes to the file system. Identify the two correct statements describing the attributes recorded.

1. A. /var/dhcp Attribute: size uid gid mode acl
2. B. /etc/hosts Attributes: size uid gid mode acl intime dest
3. C. /var/spool/mqueue Attribute: size uid gid mode acl dirmtime
4. D. /etc/security/exec_attr Attribute: size uid mode acl mtime devnode
5. E. /export/home/kate/.profile Attributes: uid gid mode acl dirmtime
6. F. /export/home/rick/.profile Attributes: size uid gid mode acl mtime contents

Correct Answer: DF
D: According to line /etc/security F: According to line /export/home
Not E: According to line IGNORE dirmtime
Note: In default mode, the bart compare command, as shown in the following example, checks all the files installed on the system, with the exception of modified directory timestamps (dirmtime):
CHECK all IGNORE dirmtime
Note 2: The Basic Audit Reporting Tool (BART) feature of Oracle Solaris enables you to comprehensively validate systems by performing file-level checks of a system over time. By creating BART manifests, you can easily and reliably gather information about the components of the software stack that is installed on deployed systems.
BART is a useful tool for integrity management on one system or on a network of systems.
