The core dump configuration in your non global zone is

A user is running a process in a non-global zone (testzone) and the process crashes. The process information is:
user126632618017:46:42pts/20:00/usr/bin/bash
When the user's process crashes in testzone, a non-global zone, where will the core dump be saved?

• A. The file will be stored in the non-global zone's directory:/var/core/pprocess/core.hash.2663.
• B. The file will be saved in the global zone's directory: /var/core/core.bash.2663.
• C. A core file cannot be generated in a non-global zone because it shares the kernel with the global zone.

• B. Set up a IP address on the AI install server.
• C. The DHCP server must be enabled on the install server and must provide the DHCP service for the clients.
• D. DHCP must be available on the network for the Install server and the clients, but the install server does not need to be the DHCP server.
• E. Download the AI boot imag
• F. The image must be the same version as the Oracle Solaris OS that you plan to install on the client.
• G. Download the text install image into the IPS repository.
• H. Install the AI installation tools.
• I. Create the AI install servic
• J. Specify the path to the AI network boot image ISO file and the path where the AI net image ISO file should be unpacked.
• K. Create the AI install servic
• L. Specify the path to the AI network boot image ISO file and the path to the IPS repository.

Answer: BDFGI

Explanation:
B: Configure the AI install server to use a static IP address and default route.
D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server for use with AI. The DHCP server must be able to provide DNS information to the systems to be installed.
E: An automated installation of a client over the network consists of the following high-level steps:
1. The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server.
2. The install server provides a boot image to the client.
3. Characteristics of the client determine which installation instructions and which system configuration instructions are used to install the client.
4. The Oracle Solaris 11 OS is installed on the client, pulling packages from the package repository specified by the installation instructions in the AI install service.
G: Install the AI tool set.
Use the installadm create-service command to create an AI install service. Give the service a meaningful name, and specify the path where you want the service created. Specify the source of the network boot image (net image) package or ISO file.
installadm create-service [-n svcname] [-s FMRI_or_ISO] [-d imagepath]
-d imagepath
The imagepath is the location of the new install service. The install-image/solaris-auto- install package is installed to this location, or the specified ISO file is expanded at this location.

NEW QUESTION 12
Which two options describe how to override the default boot behavior of an Oracle Solaris 11 SPARC system to boot the system to the single-user milestone?

• A. from the ok prompt, issue this command: boot -m milestone=single-user
• B. From the ok prompt, issue this command: boot -m milestone/single-user
• C. From the ok prompt, issue this command: boot -milestone=single-user
• D. From the ok promp
• E. issue this command:boot -s
• F. From from the ok prompt, issue this command:boot -m milestone=s

Answer: AD

Explanation:
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.

The su command by default makes an entry into the log file for every su command attempt. The following is a single line from the file:
SU 12/18 23:20 + pts/1 user1-root What does the + sign represent?

• A. unsuccessful attempt
• B. successful attempt
• C. The attempt was from a pseudo terminal, and not the console.
• D. The attempt was from a user that is in the adm group, same as root.
• E. Time zone is not set.

Answer: B

Explanation:
The sulog file, /var/adm/sulog, is a log containing all attempts (whether successful or not) of the su command. An entry is added to the sulog file every time the su command is executed. The fields in sulog are: date, time, successful (+) or unsuccessful (-), port, user executing the su command, and user being switched to. In the preceding example, all su attempts were successful, except for the attempt on 2/23 at 20:51, when user pete unsuccessfully attempted to su to user root.
Look for entries where an unauthorized user has used the command inappropriately. The following entry shows a successful (indicated by +) su from user userid to root.
SU 03/31 12:52 + pts/0 <userid>-root
