NEW QUESTION # 106
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 saved in non-global zone's directory: /var/core/core.bash.2663
- B. A core file cannot be generated in a non-global zone because it shares the kernel with the global zone.
- C. The file will be stored in the global zone's directory: /var/core/pprocess/core.bash.2663.
- D. The file will be stored in the non-global zone's directory: /var/core/pprocess/core.hash.2663.
- E. The file will be saved in the global zone's directory: /var/core/core.bash.2663.
Answer: A
Explanation:
The line
init core file pattern: /var/core/core.%f.%p
will be used for the non-global process to determine the destination of the dump file.
Note: When a process is dumping core, up to three core files can be produced: one in the per-process location, one in the system-wide global location, and, if the process was running in a local (non-global) zone, one in the global location for the zone in which that process was running.

NEW QUESTION # 108
Subnets are created by using________.
- A. netmask
- B. broadcast
- C. unicast
- D. subnet
Answer: A
Explanation:
The process of subnetting involves the separation of the network and subnet portion of an address from the host identifier. This is performed by a bitwise AND operation between the IP address and the (sub)network prefix. The result yields the network address or prefix,and the remainder is the host identifier.
The routing prefix of an address is written in a form identical to that of the address itself. This is called the network mask,or netmask,of the address. For example,a specification of the most-significant 18 bits of an IPv4 address,11111111.11111111.11000000.00000000,is written as 255.255.192.0.

How to Activate an Existing Boot Environment beadm activate beName
beName is a variable for the name of the boot environment to be activated.
Note the following specifications.
beadm activate beName activates a boot environment by setting the bootable pool property, bootfs, to the value of the ROOT dataset of the boot environment that is being activated.
beadm activate sets the newly activated boot environment as the default in the menu.lst file.
The newly activated boot environment is now the default on the x86 GRUB menu or SPARC boot menu.

NEW QUESTION # 112
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. crontab - e vi
- B. EDITOR=vi
- C. env
- D. crontab=vi
Answer: B
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.

When you issue the "gzip: zommand not found" message is displayed. You need to install the gzip utility on your system.
Which command would you use to check if the gzip utility is available from the default publisher for installation?
- A. pkg list SUNWgzip
- B. pkg contents gzip
- C. pkg info|grep gzip
- D. pkg search gzip
Answer: D
Explanation:
Searching for Packages
Use the pkg search command to search for packages whose data matches the specified pattern.
Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search command returns the names of packages that match the query.
pkg search
search [-HIaflpr] [-o attribute ...] [-s repo_uri] query
Search for matches to the query, and display the results.
Which tokens are indexed are action-dependent, but may include content hashes and pathnames.
Note: pkg is the retrieval client for the image packaging system. With a valid configuration, pkg can be invoked to create locations for packages to be installed, called 'images', and install packages into those images. Packages are published by publishers, who may make their packages available at one or more repositories. pkg, then, retrieves packages from a publisher's repository and installs them into an image.
NEW QUESTION # 120
user1 has a disk quota of 0.5 MB. The user attempts to run the following command on a file called .bigfile that is 495 KB in size:
cp bigfile /tmp
Will the command execute successfully?
- A. No. The command will fail because it will cause him to exceed his user quota.
- B. No. A user cannot place files into the /tmp directory.
- C. Yes.Quotas do notinclude any of the system files such as /tmp /swap.
- D. Yes. The quota is set at the directory level, not the user level.
Answer: C
Explanation:
UFS quotas enable system administrators to control the size of file systems. Quotas limit the amount of disk space and the number of inodes, which roughly corresponds to the number of files, that individual users can acquire. For this reason, quotas are especially useful on the file systems where user home directories reside. As a rule, the public and /tmp file systems usually do not benefit significantly by establishing quotas.
Note: The cp command copies files and directories.

NEW QUESTION # 121
A change in your company's security policy now requires an audit trial of all administrators assuming the sysadm role, capturing:
There are two command necessary to accomplish this change. One is a rolemod command. What is the other?
- A. auditconfig set flags=lo, ex sysadm
- B. auditconfig -setpolicy +argv
- C. auditconfig set policy=argv
- D. auditconfig -setflags lo, ex sysadm
Answer: B
Explanation:
Audit Significant Events in Addition to Login/Logout (see step 2 below) Use this procedure to audit administrative commands, attempts to invade the system, and other significant events as specified by your site security policy.
For all users and roles, add the AUE_PFEXEC audit event to their preselection mask.
# usermod -K audit_flags=lo, ps:no username
# rolemod -K audit_flags=lo, ps:no rolename
# auditconfig -setpolicy +argv
3 - Record the environment in which audited commands are executed.
# auditconfig -setpolicy +arge
Note: [-t] -setpolicy [+|-]policy_flag[, policy_flag ...]
Set the kernel audit policy. A policy policy_flag is literal strings that denotes an audit policy.
A prefix of + adds the policies specified to the current audit policies. A prefix of - removes the policies specified from the current audit policies. No policies can be set from a local zone unless the perzone policy is first set from the global zone.
