A. Install the AI installation tools.
B. Create the AI install service. Specify the path to the AI network boot image ISO file and the path to the IPS repository.
C. Create the AI install service. Specify the path to the AI network boot image ISO file and the path where the AI net image ISO file should be unpacked.
D. The DHCP server must be enabled on the install server and must provide the DHCP service for the clients.

H. Create a local IPS repository on the AI Install server and start the repository server service, the publisher origin to the repository file.

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-autoinstall package is installed to this location, or the specified ISO file is expanded at this location.

NEW QUESTION # 21
You are attempting to edit your crontab file in the bash shell. Instead of getting your usual vi interface, you are presented with an unfamiliar interface. In order to have your editor of choice-viwhat command must you type after exiting the unfamiliar editor?

A. EDITOR=vi
B. crontab=vi
C. env
D. crontab - e vi

Answer: A

Explanation:
Set the EDITOR variable to vi.
Commands like `crontab -e` will use ed per default. If you'd like to use some better editor (like vi)
you can use the environment variable EDITOR:
# EDITOR=vi; crontab -e will open the users crontab in vi. Of course you can set this variable
permanently.
Incorrect answers
C: -e Edits a copy of the current user's crontab file, or creates an empty file to edit if crontab does not exist. When editing is complete, the file is installed as the user's crontab file. If a username is given, the specified user's crontab file is edited, rather than the current user's crontab file; this can only be done by a user with the solaris.jobs.admin authorization. The environment variable EDITOR determines which editor is invoked with the -e option. The default editor is ed(1). All crontab jobs should be submitted using crontab. Do not add jobs by just editing the crontab file, because cron is not aware of changes made this way.
Reference: Setting the default editor

NEW QUESTION # 22

B. Enter umask 000on the command line, or includeit in each user's startup script.
C. It isnot possible to automatically set the execute bit on with the umasksetting, or vi option.
D. Enter umask-son the command line, or include it in each user's startup script.
E. Enter umask777 on the command line, or include it in each user's startup script.
F. Enter set-ovion thecommand line, or include itin each user's startup script.

Answer: B

Explanation:
Unlike DOS, which uses the file extension to determine if a file is executable or not,
UNIX relies on file permissions.
The value assigned by umask is subtracted from the default.
User's file creation mask. umask sets an environment variable which automatically sets file
permissions on newly created files. i.e. it will set the shell process's file creation mask to mode.
umask 000 would grant full permissions.
Note:777 full permissions
