Oracle Solaris 11 System Administration Sample Questions (Q225-Q230):

NEW QUESTION # 225
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. A core file cannot be generated in a non-global zone because it shares the kernel with the global zone.
B. The file will be stored in the non-global zone's directory: /var/core/pprocess/core.hash.2663.
C. The file will be stored in the global zone's directory: /var/core/pprocess/core.bash.2663.
D. The file will be saved in non-global zone's directory: /var/core/core.bash.2663
E. The file will be saved in the global zone's directory: /var/core/core.bash.2663.

Answer: D

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 # 226
Which three of the components would degrade performance if used in a ZFS storage pool, and are not recommended configurations?

A. an EDI disk
B. a Veritas Volume Manager (VxVM) volume
C. a LUN in a hardware RAID array
D. a file on a UFS file system
E. a Solaris Volume Manager (SVM) volume
F. a disk slice from an SMI labeled disk

Answer: B,D,E

Explanation:
A: ZFS also allows you to use UFS files as virtual devices in your storage pool. This feature is aimed primarily at testing and enabling simple experimentation, not for production use.
The reason is that any use of files relies on the underlying file system for consistency. If you create a ZFS pool backed by files on a UFS file system, then you are implicitly relying on UFS to guarantee correctness and synchronous semantics. However, files can be quite useful when you are first trying out ZFS or experimenting with more complicated layouts when not enough physical devices are present. All files must be specified as complete paths and must be at least 64 Mbytes in size.
B, E: You can construct logical devices for ZFS using volumes presented by software-based volume managers, such as Solaris Volume Manager (SVM) or Veritas Volume Manager (VxVM). However, these configurations are not recommended. While ZFS functions properly on such devices, less-than-optimal performance might be the result.

NEW QUESTION # 227
How are operating system updates distributed in the Oracle Solaris 11 environment?

A. Patches are download from http: //support.oracle.com either automatically or manually. All software packages are then updated manually from the command line using the smpatch or patchadd commands.
B. Software updates,published as packages to an OS image. All software packages are then updated manually from the command line using the pkg command.
C. Updates are only available to customers with an active support contract. The updates are distributed through the My Oracle Support web portal and installed in a central location. All software packages are then updated manually from the command line using the smpatch command.
D. Software updates are published as packages to a repository. All software packages are then updated manually from the command line using the pkg command.

Answer: D

Explanation:
*Updating all of the packages on your installed system - To update all of the packages on your system that have available updates,use the pkg update command,as follows:
# pkg update Running this command updates packages that you might not otherwise consider updating,for example,kernel components and other low-level system packages.
*Adding or updating individual packages - To add individual software packages,use the pkg install command. Any dependent packages are also updated at the same time.
*install package updates that deliver fixes- A pkg update operation might include bug fixes,so the operation is similar to applying a specific patch or patches in previous Oracle Solaris releases.
Note: The IPS interfaces first check for updates for currently installed packages before retrieving them via the network. By default,interfaces check repository catalogs in the following locations:
*The default installation repository at pkg.oracle.com/solaris/release.
*The support repository in My Oracle Support. This repository is restricted to users with Oracle Solaris 11 Express support contracts,and it contains packages with the latest bug fixes. For this reason,a support contract must be purchased for production deployments.

This message means that either the user is not listed in the cron.allow file (if the file exists), or the user is listed in the cron.deny file.
You can control access to the crontab command by using two files in the /etc/cron.d directory: cron.deny and cron.allow. These files permit only specified users to perform crontab command tasks such as creating, editing, displaying, or removing their own crontab files.
The cron.deny and cron.allow files consist of a list of user names, one user name per line.
