Upgrade to Oracle Solaris 11 System Administrator Practice Tests and PDFs

Use the installadm set-criteria command to update the client criteria associated with an AI manifest that you already added to a service using installadm add-manifest. Use the installadm add-manifest command to add a custom AI manifest to an install service. The value of manifest is a full path and file name with .xml extension. The manifest file contains an AI manifest (installation instructions). The manifest file can also reference or embed an SC manifest (system configuration instructions). Incorrect answers: A: The sys-unconfig command is used to restore a system's configuration to an "as-manufactured" state, ready to be reconfigured again. C: You can use the sysconfig create-profile command to create a new system configuration profile. The sysconfig command affects all functional groupings in the Solaris instance. D: Use the installadm create-profile command to add a system configuration profile to an install service. The create-profile subcommand validates profiles before adding them to the install service. Specify criteria so that appropriate clients select that configuration profile. If no criteria are specified, all clients use this profile.

Example: Encrypting a ZFS File System by Using a Raw Key In the following example, an aes-256-ccm encryption key is generated by using the pktool command and is written to a file, /cindykey.file. # pktoolgenkeykeystore=file outkey=/cindykey.filekeytype=aeskeylen=256 Then, the /cindykey.file is specified when the tank/home/cindy file system is created. # zfs create -o encryption=aes-256-ccm -o keysource=raw,file:///cindykey.file tank/home/cindys Reference: Oracle Solaris ZFS Administration Guide, Examples of Encrypting ZFS File Systems

* (Not A, B, C): interval (here 10 seconds): Specifies the length in seconds to pause between each interval report. * duration (here 24 h) * -R report[,report] (here high) Print a summary report. high Print a summary report detailing the highest usage of each resource and zone during any interval of thezonestat utility invocation. Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as a percentage of system resources and the zone's configured limits. The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval. The default output is a summary of cpu, physical, and virtual memory utilization. The -r option can be used to choose detailed output for specific resources.

Comparing sysidcfg File Keywords to System Configuration Profile Directives The following table compares sysidcfg file keywords with example AI system configuration profile specifications. sysidcfg File Keyword System Configuration Profile Directives Etc.

A: If the network is setup to perform automated installations, you can perform a text installation over the network by setting up an install service on the network and selecting a text installation when the client system boots. B: After a fresh install of Solaris 11 express, only the console mode is activated. To add Gnome, simply do : $ sudopkg install slim_install This will install additional packages that are not installed by default. D: The text installer advantages over the GUI installer include: * In addition to modifying partitions, the text installer enables you to create and modify VTOC slices within the Solaris partition. F: How do I upgrade my Solaris 10 or lower systems to Solaris 11? Unfortunately, you CAN'T. There is no direct upgrade installer or other tool that will allow you to upgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10. Incorrect answers: E: Both installers can be used to install Oracle Solaris on the x86 platform. The text installer can also be used to install Oracle Solaris on the SPARC platform. G: Both installers enable you to select, create, or modify disk partitions during an installation. H: Both installers can be used to install Oracle Solaris on the x86 platform. The text installer can also be used to install Oracle Solaris on the SPARC platform.

The framework enables providers of cryptographic services to have their services used by many consumers in the Oracle Solaris operating system. Another name for providers is plugins. The framework allows three types of plugins: * User-level plugins - Shared objects that provide services by using PKCS #11 libraries, such as pkcs11_softtoken.so.1. * Kernel-level plugins - Kernel modules that provide implementations of cryptographic algorithms in software, such as AES. Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware. * Hardware plugins - Device drivers and their associated hardware accelerators. The Niagara chips, the ncp and n2cp device drivers, are one example. A hardware accelerator offloads expensive cryptographic functions from the operating system. The Sun Crypto Accelerator 6000 board is one example. Reference: Oracle Solaris Cryptographic Framework http://docs.oracle.com/cd/E19963-01/html/821-1456/scf-10.html

You can use the pkg set-publisher command to change a publisher URI. Changing a Publisher Origin URI To change the origin URI for a publisher, add the new URI and remove the old URI. Use the -g option to add a new origin URI. Use the -G option to remove the old origin URI. # pkg set-publisher -g http://pkg.example.com/support -G Note: You can use either the install or update subcommand to update a package. The install subcommand installs the package if the package is not already installed in the image. If you want to be sure to update only packages that are already installed, and not install any new packages, then use the update subcommand.

A: + Indicates the file/directory was added in the later dataset C: R Indicates the file/directory was renamed in the later dataset E: - Indicates the file/directory was removed in the later dataset G: M Indicates the file/directory was modified in the later dataset Note: Identifying ZFS Snapshot Differences (zfs diff) You can determine ZFS snapshot differences by using the zfs diff command. The following table summarizes the file or directory changes that are identified by the zfs diff command. File or Directory Change Identifier * File or directory i

How to Create an iSCSI LUN The following steps are completed on the system that is providing the storage device. 1.Create a ZFS storage pool. Example: target# zpool create sanpool mirror c2t3d0 c2t4d0 (C)2. Create a ZFS volume to be used as a SCSI LUN. (D)3. Create a LUN for the ZFS volume. Example: target# stmfadm create-lu /dev/zvol/rdsk/sanpool/vol1 Logical unit created: 600144F0B5418B0000004DDAC7C10001 4. Confirm that the LUN has been created. Example target# stmfadm list-lu LU Name: 600144F0B5418B0000004DDAC7C10001 (F) 5. Add the LUN view. This command makes the LUN accessible to all systems. target# stmfadm add-view 600144F0B5418B0000004DDAC7C10001 How to Create the iSCSI Target This procedure assumes that you are logged in to the local system will contains the iSCSI target. Note: The stmfadm command manages SCSI LUNs. Rather than setting a special iSCSI property on the ZFS volume, create the volume and use stmfadm to create the LUN. (H) 1. Enable the iSCSI target service. target# svcadm enable -r svc:/network/iscsi/target:default (I) 2. Create the iSCSI target. target# itadm create-target Reference: Oracle Solaris Administration: Devices and File Systems, Configuring iSCSI Devices With COMSTAR

A: ZFS can automatically share file systems by setting the sharenfs property. Using this property, you do not have to modify the /etc/dfs/dfstab file when a new file system is shared. The sharenfs property is a comma-separated list of options to pass to the share command. The value on is an alias for the default share options, which provides read/write permissions to anyone. The value off indicates that the file system is not managed by ZFS and can be shared through traditional means, such as the /etc/dfs/dfstab file. All file systems whose sharenfs property is not off are shared during boot. Incorrect answers: D: A share can define options for both NFS and SMB sharing.
