Question 1

The core dump configuration for your system is:

A user is running a process in the global zone and the process crashes. The process information is:

User1 2663 2618 0 17:46:42 pts/2 0:00 /usr/bin/bash

The server host name is: zeus

What will the per-process core file be named?

Acore.bash.2663.global

Bcore.bash.2663.zeus

C/var/core/core.bash.2663

D/var/core/core.bash.2663.global

Correct : C

Note the first line:

global core file pattern: /globalcore/core.%f.%p

The program name is bash

The runtime process ID is 2663

Note: By default, the global core dump is disabled. You need to use thecoreadmcommand with the-e globaloption to enable it. The-goption causes the command to append the program name(%f)and the runtime process ID(%p)to the core file name.

Question 2

Select two statements that correctly describe the capabilities of the Distribution Constructor.

AISO images for use with the Automated Installer (AI) can be created.

BBootable USB images can be created for SPARC and x86 architectures.

CA single installation server can be used to create ISO images for SPARC and x86 architectures.

DCheckpoints can be used to pause the build, allowing scripts to run that modify the resulting ISO Image.

EA single Installation server can be used to create ISO images for Solaris 10 and Solaris11 operating systems.

Correct : A, D

A: You can use the distribution constructor to create the following types of Oracle Solaris images:

* (A) x86 or SPARC ISO Image for Automated Installations

* Oracle Solaris x86 live CD image

* x86 or SPARC Oracle Solaris text installer image

* x86 Oracle Solaris Virtual Machine

Note: You can use the distribution constructor to build custom Oracle Solaris images. Then, you can use the images to install the Oracle Solaris software on individual systems or multiple systems. You can, also, use the distribution constructor to create Virtual Machine (VM) images that run the Oracle Solaris operating system.

D: Checkpointing Options

You can use the options provided in the distro_const command to stop and restart the build process at various stages in the image-generation process, in order to check and debug the image that is being built. This process of stopping and restarting during the build process is called checkpointing.

Question 3

Which three statements accurately describe the Automated Installation (AI) client?

AIf the AI client does not match any criteria to use a custom manifest or script, the default manifest is used.

BIf the AI client does not match any criteria to use a custom manifest or script, the automated installation aborts.

CAny manifest or script in a service can be designated to be the default for that service.

DOnly the default.xml file is used as the default AT client manifest.

EIf a client system does not use any SC profile, then an interactive tool opens on that client at first boot after that client installation to complete the configuration of that client.

FIf a client system does not use any SC profile, then the install server will use the default SC profile.

Correct : A, C, E

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.

Question 4

You are going to create live zones on you server. Disk space is critical on this server so you need to reduce the amount of disk space required for these zones. Much of the data required for each of these zones is identical, so you want to eliminate the duplicate copies of data and store only data that is unique to each zone.

Which two options provide a solution for eliminating the duplicate copies of data that is common between all of these zones?

ACreate the zones by using sparse root zones.

BSet the dedup property to on and the dedupratio to at least 1.5 for the zpool.Create a separate ZFS file system for each zone in the zpool.

CPut all of the zones in the same ZFS file system and set the dedupratio property for the ZFS file system to at least 1.5.

DPut all of the zones in the same ZFS file system and set the dedup property for the file system to on.

EPut each zone in a separate ZFS file system within the same zpool. Set the dedup property to on for each ZFS file system.

Correct : D, E

n Oracle Solaris 11, you can use the deduplication (dedup) property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored, and common components are shared between files.

Question 5

Which two statements are true concerning the creation of user accounts by using the useradd command?

ABy default, it will create the user's home directory.

BNew user accounts are unlocked but must change their password at their first login.

CNew user accounts are in a pending activation state until a password is assigned to them.

DBy default, a new group will be added for each new user account.

EBy default, the UID of a new user account will be the next available number above the highest number currently assigned.

FBy default, the UID of a new user account with be the lowest available unused number for nonsystem accounts.
