Correct Answer: D

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.

Correct Answer: AD

By default, Solaris will boot to the pseudo milestone "all" and start all services. This behaviour can be changed at boot time using either "-s" to reach single-user, or the new SMF option "-m milestone=XXX" (see kernel(1M) for a list of the bootable milestones) to select an explicit milestone.

Note: boot -s is the same as: boot -m milestone=single-user

with the difference being that the former is a lot less to type and is what most SysAdmins will be familiar with.

Correct Answer: B

The zfs list command provides an extensible mechanism for viewing and querying dataset information.

You can list basic dataset information by using the zfs list command with no options. This command displays the names of all datasets on the system and the values of their used, available, referenced, and mountpoint properties. For more information about these properties, see Introducing ZFS Properties.

For example:

# zfs list NAME USED AVAIL REFER MOUNTPOINT pool 476K 16.5G 21K /pool pool/clone 18K 16.5G 18K /pool/clone pool/home 296K 16.5G 19K /pool/home pool/home/marks 277K 16.5G 277K /pool/home/marks pool/home/marks@snap 0 - 277K pool/test 18K 16.5G 18K /test

Correct Answer: BF

B: Setting the default route on Solaris is easy. If you are trying to just set the route temporarily you can use the route command:

Route add default

Example:

Route add default 192.168.1.1

Note: Route command manipulates the kernel routing tables. Routing is the process of forwarding a packet from one computer to another. It is based on the IP address in the IP packet header and netmask.

F: If you want the route to be persisted when you reboot the system, you will need to set the route in the / etc/defaultrouter file.

/etc/defaultrouter Example: Echo 192.168.1.1 > /etc/defaultrouter

Correct Answer: B

The /etc/passwd file contains basic user attributes. This is an ASCII file that contains an entry for each user. Each entry defines the basic attributes applied to a user.

/etc/shadow file stores actual password in encrypted format for user's account with additional properties related to user password i.e. it stores secure user account information. All fields are separated by a colon (:) symbol. It contains one entry per line for each user listed in /etc/passwd file.

Correct Answer: A

Here we should use SIGTERM to terminate the process.

Note:

When no signal is included in the kill command-line syntax, the default signal that is used is ?5 (SIGKILL).

Using the ? signal (SIGTERM) with the kill command ensures that the process terminates promptly.

However, the ? signal should not be used to kill certain processes, such as a database process, or an

LDAP server process. The result is that data might be lost.

Tip - When using the kill command to stop a process, first try using the command by itself, without

including a signal option. Wait a few minutes to see if the process terminates before using the kill

command with the -9 signal.

Correct Answer: BE

Image Packaging System (IPS) is a new network based package management system included in Oracle Solaris 11. It provides a framework for complete software lifecycle management such as installation, upgrade and removal of software packages. IPS also enables you to create your own software packages, create and manage package repositories, and mirror existing package repositories.

Oracle Solaris software is distributed in IPS packages. IPS packages are stored in IPS package repositories, which are populated by IPS publishers.

E: The following command displays property information about the local repository.

$ pkgrepo get -s /export/repoSolaris11

SECTION PROPERTY VALUE publisher prefix solaris repository description This\ repository\ serves\ a\

copy\ of\ the\ Oracle\ Solaris\ 11\ Build\ 175b\ Package\ Repository. repository name Oracle\ Solaris\ 11\

Build\ 175b\ Package\ Repository repository version 4

The value of the publisher prefix specifies that solaris is to be used in the following cases:

When more than one publisher's packages are present and no publisher is specified in the package name

in the pkg command

When packages are published to the repository and no publisher is specified.

Correct Answer: A

The main tool for setting up cron jobs is the crontab command, though this is not available on every Unix variant. Typically under Solaris or Linux one would create a new crontab or edit an existing one, using the command; crontab -e

Use the ls -l command to verify the contents of the/var/spool/cron/crontabs file.

Correct Answer: ACE

Each client uses one and only one AI manifest to complete its installation. The AI manifest is selected for a client according to the following algorithm:

* If no custom AI manifests are defined for this install service, the default AI manifest is used. The default AI manifest is not associated with any client criteria etc.

Each client can use any number of system configuration profiles. If a client system does not use any configuration profile, then an interactive tool opens on that client at first boot after that client installation to complete the configuration of that client.
