NEW QUESTION 68
View the Exhibit to inspect the boot environment Information displayed within a non global zone on your system.
Which two options describe the solaris-1 boot environment?
- A. The solaris-1 boot environment is associated with a non active global zone boot environment.
- B. The solaris-1 boot environment was created automatically when the non global zone was created.
- C. The solaris-1 boot environment is not bootable.
- D. The solaris-1 boot environment was created in the non-global zone using the beadm create command.
- E. The solaris-1 boot environment is incomplete.
Answer: C,D
Explanation:
A: The - of the Active Column indicates that this boot environment is inactive,and hence not bootable.
Note: The values for the Active column are as follows: R - Active on reboot.
N - Active now.
NR - Active now and active on reboot.
"-" - Inactive.
"!" - Unbootable boot environments in a non-global zone are represented by an exclamation point.
D: beadm create
Creates a new boot environment name,beName.
Note: beadm list
Lists information about the existing boot environment,which is be Name,or lists information
for all boot environments if be Name is not provided.
Note: Using beadm Utility (Tasks)
You can use the beadm utility to create and manage snapshots and clones of your boot
environments.
Note the following distinctions relevant to boot environment administration:
*A snapshot is a read-only image of a dataset or boot environment at a given point in time. A snapshot is not bootable.
*A boot environment is a bootable Oracle Solaris environment,consisting of a root dataset and,optionally,other datasets mounted underneath it. Exactly one boot environment can be active at a time.
*A clone of a boot environment is created by copying another boot environment. A clone is bootable.

You log in to the system as user1, then switch user to root by using the su -command. After entering the correct password, yon enter the following commands:
whoami;who am i;id
Which option correctly represents the output?
- A. uid=0(root) gid=0(root) root user1 console Dec 30 20:20
- B. user1console Dec 3020:20 root uid=0(root)gid=0(root)
- C. uid-0(root)gid=0(root) user1console Dec 3020:20 root
- D. root user1console Dec 3020:20 uid=0(root)gid=0(root)
Answer: D
Explanation:
*The whoami utility displays your effective user ID as a name.
Here this would beroot.
*who am i
The command who shows who is logged on.
Here this would be:
user1 console Dec 30 20:20
*The id utility displays the user and group names and numeric IDs, of the
calling process, to the standard output. If the real and effective IDs
are different, both are displayed, otherwise only the real ID is dis-
played.
Here this would be:
uid=0(root) gid=0(root)
Note: Each UNIX proces has 3 UIDs associated to it. Superuser privilege is UID=0.Real UID--------This is the UID of the user/process that created THIS process. It can be changed only if the running process has EUID=0.Effective UID-------------This UID is used to evaluate privileges of the process to perform a particular action. EUID can be change either to RUID, or SUID if EUID!=0. If EUID=0, it can be changed to anything.Saved UID---------If the binary image file, that was launched has a Set-UID bit on, SUID will be the UID of the owner of the file. Otherwise, SUID will be the RUID. '
NEW QUESTION 71
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 the global zone's directory: /var/core/core.bash.2663.
- B. The file will be stored in the global zone's directory: /var/core/pprocess/core.bash.2663.
- C. The file will be saved in non-global zone's directory: /var/core/core.bash.2663
- D. A core file cannot be generated in a non-global zone because it shares the kernel with the global zone.
- E. The file will be stored in the non-global zone's directory:
/var/core/pprocess/core.hash.2663.
Answer: C
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.

F (not E): The Oracle Solaris Zones partitioning technology is used to virtualize operating system services and provide an isolated and secure environment for running applications. A zone is a virtualized operating system environment created within a single instance of the Oracle Solaris operating system.
NEW QUESTION 79
How are operating system updates distributed in the Oracle Solaris 11 environment?
- A. Software updates, published as packages to an OS image. All software packages are then updated manually from the command line using the pkg command.
- B. 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.
- C. Software updates are published as packages to a repository. All software packages are then updated manually from the command line using the pkg command.
- D. 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.
Answer: C
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.

You need to migrate a UFS file system named /production_ufs to a ZFS file system named
/production_ufs. The /production_ufs file system cannot be taken down or be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.
Which method allows you to meet both requirements?
1 . Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.
2 . When the copy is complete, /production_zfs will contain an up-to date copy of
/production_ufs
- A. Create a snapshot of the UFS file system. Create the new ZFS file system. Use cpio to copy data from the snapshot to the new ZFS file system.
- B. Create a new Boot Environment. Create the ZFS file system. Use lucreate -m to copy data from the Current UFS file system to the new ZFS file system.
- C. Create the new ZFS file system by using zfs create import to import data from the existing UFS file system into the new ZFS file system
- D. Create the new zfs file system by using the zfs create -o shadow.
- E. Mirror the existing UFS file system by using SVM.After both submissions are in sync, migrate one of the submissions to a ZFS file System by using Live Upgrade.
Answer: D
Explanation:
Migrating Data With ZFS Shadow Migration
ZFS shadow migration is a tool you can use to migrate data from an existing file system to a new file system. A shadow file system is created that pulls data from the original source as necessary.
You can use the shadow migration feature to migrate file systems as follows:
* A local or remote ZFS file system to a target ZFS file system
* A local or remote UFS file system to a target ZFS file system
Shadow migration is a process that pulls the data to be migrated:
* Create an empty ZFS file system.
* Set the shadow property on an empty ZFS file system, which is the target (or shadow) file system, to point to the file system to be migrated.
For example:
# zfs create -o shadow=nfs://system/export/home/ufsdata users/home/shadow2
* Data from file system to be migrated is copied over to the shadow file system.

A datalink can best be described as______.
- A. the software connecting the Internet Layer and the Physical Layer
- B. a driver for a Network Interface Card
- C. a device that provides Classless Inter-Domain Routing
- D. a logical object used for IP Multipathing
Answer: D
Explanation:
The command dladm is used to configure data-link interfaces in Sun Solaris. A configured data-link is represented in the system as interface that can be used for TCP/IP. Each data-link relies on either a single network device or an link aggregation device to send & recieve packets.
Network interfaces provide the connection between the system and the network. These interfaces are configured over data links,which in turn correspond to instances of hardware devices in the system.
In the current model of the network stack,interfaces and links on the software layer build on the devices in the hardware layer. More specifically,a hardware device instance in the hardware layer has a corresponding link on the data-link layer and a configured interface on the interface layer. This one-to-one relationship among the network device,its data link,and the IP interface is illustrated in the figure that follows.

- C. All packages within an IPS package repository reside in a catalog.
- D. The packages in a catalog are associated with a specific publisher.
- E. It is an ISO image of the Solaris installation media.
Answer: B,D
Explanation:
Image Packaging System (IPS) is a new network based package management system included in Oracle Solaris 11. It provides a framework for complete software lifecycle management such as installation, upgrade and removal of software packages. IPS also enables you to create your own software packages, create and manage package repositories, and mirror existing package repositories.
Oracle Solaris software is distributed in IPS packages. IPS packages are stored in IPS package repositories, which are populated by IPS publishers.
E: The following command displays property information about the local repository.
$ pkgrepo get -s /export/repoSolaris11
SECTION PROPERTY VALUE publisher prefix solaris repository description This\ repository\
serves\ a\ copy\ of\ the\ Oracle\ Solaris\ 11\ Build\ 175b\ Package\ Repository.
repository name Oracle\ Solaris\ 11\ Build\ 175b\ Package\ Repository
repository version 4
The value of the publisher prefix specifies that solaris is to be used in the following cases:
When more than one publisher's packages are present and no publisher is specified in the
package name in the pkg command
When packages are published to the repository and no publisher is specified.

You want the system to generate an email notification each time one of the services has changed its state. Which option would send an email message to the system administrator whenever a service changes to the maintenance state?
- A. Use the svccfg setnotify command to create a notification and send an email when a service enters the maintenance state.
- B. Use the scvadm command to enable the notification service. Set the -g maintenance option on the netnotify service to send an email when a service enters the maintenance state.
- C. Make an entry in the /etc/syslog.conf file to instruct syslogd to send an email alert when it receives a message from the SMF facility that a service has changed to the maintenance state.
- D. Use the setsc command in ALOM to enable the mail alerts to be sent to a specified email address whenever the fault management facility detects a service change to the maintenance state.
Answer: A
Explanation:
This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to use either SMTP or SNMP. Normally,you would only select SNMP if you already have SNMP configured for some other reason.
By default,SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring,you can configure additional traps for other state transitions.
1.Become an administrator or assume a role that includes the Service Management rights profile.
2.Set notification parameters.
Example: The following command creates a notification that sends email when transactions go into the maintenance state
# /usr/sbin/svccfg setnotify -g maintenance mailto:[email protected]
