What is the difference between the default configuration for zones and an immutable zone?
Correct : B
Note:
* Immutable Zones provide read-only file system profiles for solaris non-global zones.
* A zone with a read-only zone root is called an Immutable Zone. A solaris Immutable Zone preserves the zone's configuration by implementing read-only root file systems for non-global zones. This zone extends the zones secure runtime boundary by adding additional restrictions to the runtime environment. Unless performed as specific maintenance operations, modifications to system binaries or system configurations are blocked.

After installing an Oracle Solaris 11 system, you execute the following command to create a data set into which several non-global zones will be installed:
What impact will this command have on any zones installed under this ZFS data set?
Correct : E
Note:
* Oracle Solaris 11 adds transparent data encryption functionality to ZFS. All data and file system metadata (such as ownership, access control lists, quota information, and so on) are encrypted when stored persistently in the ZFS pool.
* A ZFS pool can support a mix of encrypted and unencrypted ZFS data sets (file systems and ZVOLs). Data encryption is completely transparent to applications and other Oracle Solaris file services, such as NFS or CIFS. Since encryption is a first-class feature of ZFS, we are able to support compression, encryption, and deduplication together. Encryption key management for encrypted data sets can be delegated to users, Oracle Solaris Zones, or both. Oracle Solaris with ZFS encryption provides a very flexible system for securing data at rest, and it doesn't require any application changes or qualification.
ZFS makes it easy to encrypt data and manage data encryption. You can have both encrypted and unencrypted file systems in the same storage pool. You can also use different encryption keys for different systems, and you can manage encryption either locally or remotely.

You are working on a system that appears to be hanging during the boot process. Which would be the course of action for determining which step in the boot process is causing the issue?
Correct : B
* Booting a system using the none milestone can be very useful for debugging startup problems. There is no equivalent run level to the none milestone.
* If problems with starting services occur, sometimes a system will hang during the boot. This procedure shows how to troubleshoot this problem.
2. Boot without starting any services.
This command instructs the svc.startd daemon to temporarily disable all services and start sulogin on the console.
ok boot -m milestone=none
2. Log in to the system as root.
3. Enable all services.
# svcadm milestone all
4. Determine where the boot process is hanging.
When the boot process hangs, determine which services are not running by running svcs -a. Look for error messages in the log files in /var/svc/log.
1. After fixing the problems, verify that all services have started.
Verify that all needed services are online.
# svcs -x
Verify that the console-login service dependencies are satisfied.
This command verifies that the login process on the console will run.
# svcs -l system/console-login:default
6.Continue the normal booting process.

Which three options are features of the Oracle Solaris 11 Automated Installer?
Correct : B, D, E
Note:
Not A:
* Jumpstart Profiles and Rules would have to be converted to be used in Automated Installer.
Use the js2ai utility with the -r option to convert both JumpStart rules and their associated profiles to AI criteria and manifests.
* Both Solaris Custom JumpStart and Oracle Solaris Automated Installer (AI) provide hands-free installation of multiple systems on a network. Clients are booted over the network, and once the client is booted, the installer takes over.

The command "pkg list --n *mysql-5?" produced the following output:
The IFO column of this output indicates that_______.
Correct : D
Note:
* 1 The ''i'' in the I column indicates that these packages are installed in this image.
2 An ''f'' in the F column indicates the package is frozen. If a package is frozen, you can only install or update to packages that match the frozen version.
* The pkg list command tells you whether a package is installed in the current image and whether an update is available. With no options or operands, this command lists all packages that are installed in the current image. To narrow your results, provide one or more package names. You can use wildcards in the package names. Package variants for an architecture or zone type that does not match this image are not listed.
