Question 1

You need to update an OS image on a client. The pkg publishers command displays the wrong
publisher with the wrong update:
PUBLISHER
TYPE
STATUS URI
Solaris
origin
online
http://pkg.oracle.com/solaris/release
The update is available on the updated publisher:
PUBLISHER
TYPE
STATUS URI
Solaris
origin
online
http://sysA.example.com
Select the option that describes the procedure used to update the OS image on the system from the
updated publisher.

Accepted Answer

C

Explanation: 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.

Question 2

View the Exhibit, a file named testzone.cfg: https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/1Z0-820/page_66_img_1.jpg Select the command that will use the information in this file to create a new zone named testzone2.

Accepted Answer

A

Question 3

Select the five tasks that need to be performed on the Automated Installer (AI) install server before setting up the client.

Accepted Answer

B, D, F, G, I

Explanation: B: Configure the AI install server to use a static IP address and default route. D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server for use with AI. The DHCP server must be able to provide DNS information to the systems to be installed. E: An automated installation of a client over the network consists of the following high-level steps: 1. The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server. 2. The install server provides a boot image to the client. 3. Characteristics of the client determine which installation instructions and which system configuration instructions are used to install the client. 4. The Oracle Solaris 11 OS is installed on the client, pulling packages from the package repository specified by the installation instructions in the AI install service. G: Install the AI tool set. Use the installadm create-service command to create an AI install service. Give the service a meaningful name, and specify the path where you want the service created. Specify the source of the network boot image (net image) package or ISO file. installadm create-service [-n svcname] [-s FMRI_or_ISO] [-d imagepath] -d imagepath The imagepath is the location of the new install service. The install-image/solaris-auto- install package is installed to this location, or the specified ISO file is expanded at this location.

Question 4

New features wore added to ZFS in Oracle Solaris11. Your justification to upgrade from Solaris10 to
oracle Solaris11 is that it will be possible to take advantage of the enhancements that were made to
ZFS.
Identify the three ZFS functions and features that are included in Oracle Solaris 11, but not in Solaris
10.

Accepted Answer

Explanation: A: ZFS encryption was introduced in ZFS Pool Version Number 30, Solaris Nevada b149. Filesystem encryption since Solaris 11 Express B: Deduplication was introduced in ZFS Pool Version Number 21, Solaris Nevada b128. E: Booting From a ZFS Root File System Both SPARC based and x86 based systems use the new style of booting with a boot archive, which is a file system image that contains the files required for booting. When a system is booted from a ZFS root file system, the path names of both the boot archive and the kernel file are resolved in the root file system that is selected for booting. Reference: Oracle Solaris ZFS Administration Guide, Booting From a ZFS Root File System

Question 5

Before booting test zone a non-global zone, you want to connect to the zone’s console so that you can watch the boot process. Choose the command used to connect to testzone’s console.

Accepted Answer

E

Explanation: The following options are supported: -C Connects to the zone console. Connects to the zone console. Note: After you install a zone, you must log in to the zone to complete its application environment. You might log in to the zone to perform administrative tasks as well. Unless the -C option is used to connect to the zone console, logging in to a zone using zlogin starts a new task. A task cannot span two zones Incorrect answers: B: No option -console. C, D: No option -z. Reference: man zlogin

Question 6

You have been tasked with creating a dedicated virtual network between two local zones within a
single system. In order to isolate the network traffic from other zones on that system.
To accomplish this, you will create__________.

Accepted Answer

A

Explanation: Etherstubs are pseudo ethernet NICs which are managed by the system administrator. You can create VNICs over etherstubs instead of over physical links. VNICs over an etherstub become independent of the physical NICs in the system. With etherstubs, you can construct a private virtual network that is isolated both from the other virtual networks in the system and from the external network. For example, you want to create a network environment whose access is limited only to your company developers than to the network at large. Etherstubs can be used to create such an environment. Note: Oracle Solaris 11 introduces a new and powerful network stack architecture which includes: * Networking virtualization with virtual network interface cards (VNICs) and virtual switching (etherstubs) * Tight integration with zones * Network resource management - efficient and easy to manage integrated quality of service (QoS) to enforce bandwidth limit on VNICs and traffic flows We will be examini Reference: Oracle Solaris Administration: Network Interfaces and Network Virtualization, Configuring Components of Network Virtualization in Oracle Solaris

Question 7

You are configuring NFS on a server. Select the two statements that are true.

Accepted Answer

A, C

Explanation: 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.

Question 8

This iron is displayed on the desktop of a laptop computer, which is running Oracle Solaris 11. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/1Z0-820/page_21_img_1.jpg Which two statements describe the Information conveyed by this Icon?

Accepted Answer

B, C

Explanation: B: The Network Status notification icon is only displayed on the desktop if you are using NWAM to automatically configure your network. C: All online (Wireless) Indicates all manually enabled connections in the enabled network profile are online and that the required number of connections in the enabled profile group (if such a group exists) are online. The required number is the same as those described for the All online (Wired) status. Note that at least one online connection is wireless. Reference: Oracle Solaris Administration: Network Interfaces and Network Virtualization , Checking the Status of Your Network Connection

Question 9

You are setting up a local image packaging System (IPS) package repository on your Oracle Solaris 11 server. The information and specifications that you have are as follows: The Oracle Solaris11 repository ISO image has been downloaded into the /repo directory (a zfs file system). The current publisher is: PUBLISHER TYPE STATUS URI solaris origin online http://pkg.oracle.com/solaris/release/ You will be replacing the current publisher with: PUBLISHER TYPE STATUS URI solaris origin online http://solaris.example.com/ The location of the repository will be /export/IPS. This ZFS file system has already been created. Among the steps you will perform is to set the publisher to the local repository by using the pkg set - publisher command. Which six other steps are required to set up the local IPS package repository?

Accepted Answer

A, B, D, E, G, I

Explanation: B: Set the correct permissions. Serving a Local Repository Using SMF First, create a ZFS file system to hold the repository. Next, make a local copy of the IPS repository file. Make the contents of the repository file available to the pkg.depotd(1M) server, using the lofiadm command to mount the ISO image. 4. (A) Copy the repository files to the ZFS file system you created. This will increase the performance of repository accesses and avoid the need to remount the .iso image each time the system restarts. (Be sure to use /mnt/repo, not /mnt/repo/, so that you copy the repo directory and not just the files and subdirectories in the repo directory.) # rsync -aP /mnt/repo /export/repo2010_11 You can use the df command to confirm the copy: 5. Once the files are copied, unmount the image and deallocate the block device. 6. Now that your local copy is ready, use the svccfg command to configure the repository server service, specifying the location of your local repository and setting readonly to true: (D)# svccfg -s application/pkg/server setprop pkg/inst_root=/export/repo2010_11/repo (E)# svccfg -s application/pkg/server setprop pkg/readonly=true 7. Start the pkg.depotd repository service: (G) # svcadm refresh application/pkg/server (I) # svcadm enable application/pkg/server Reference: How I Created Local Package Repositories http://www.oracle.com/technetwork/articles/servers-storage-admin/localrepositories1377242.html

Question 10

The crash dump notification on your server is: https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/1Z0-820/page_28_img_1.jpg Documentation states that there should be two core files for each crash dump in the /var/crash directory named vmdump.0 Which command should you choose to display theses two files?

Accepted Answer

A

Explanation: Decompress using savecore -f vmdump.0 savecore - save a crash dump of the operating system -f dumpfile Attempt to save a crash dump from the speci- fied file instead of from the system's current dump device. This option may be use- ful if the information stored on the dump device has been copied to an on-disk file by means of the dd(1M) command.

Question 11

You are going to use the- Automated installer (AI) to install a non global zone named zone1. You have
created a custom manifest for the non-global zone and named it zone1manifest
Which command will you use to add this custom manifest to the s11-sparc install service and
associate this custom manifest with the non-global zone?

Accepted Answer

B

Explanation: installadm add-manifest Associates manifests with a specific install service, thus making the manifests available on the network, independently from creating a service. When publishing a non-default manifest, it is required to associate criteria either via criteria entered on the command line (-c) or via a criteria XML file (-C). Incorrect answers: C: installadm create-client Accomplishes optional setup tasks for a specified client, in order to provide custom client settings that vary from the default settings used by the installadm create-service command. D: installadm create-service Creates an install service. The command provides the following functionality: - Takes an AI ISO image ( ), unpacks it, and sets up a net image in a target directory ( . The net image enables client installations. - Creates an install service and makes it available on the network. Reference: installadm

Question 12

When setting up Automated Installer (AI) clients, an interactive tool can be used to generate a
custom system configuration profile. The profile will specify the time zone, data and time, user and
root accounts, and name services used for an AI client installation. This interactive tool will prompt
you to enter the client information and an SC profile (XML) will be created.
Which interactive tool can be used to generate this question configuration?

Accepted Answer

B

Explanation: 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.

Question 13

Which modification needs to be made to the Service Management Facility before you publish a new package to the IPS repository?

Accepted Answer

D

Explanation: pkg/image_root (astring) The path to the image whose file information will be used as a cache for file data. Incorrect answers: A: pkg.depotd is the depot server for the image packaging system. It provides network access to the data contained within a package repository. Clients that do not support direct access to a repository through the file system, or for which network access is the only available or preferred method of transport, typically use the package depot. B: pkg/readonly(boolean) Sets whether modifying operations, such as those initiated by pkgsend(1), are disabled. Retrieval operations are still available. This property cannot be true when the pkg/mirror property is true. The default value is true. C: pkg/writable_root (astring) The file system path to a directory to which the program has write access. This is used with the -readonly option to enable the depot server to create files, such as search indexes, without needing write access to the package information. Reference: man pkg.depotd

Question 14

You create a flash archive of the Solaris 10 global zone on the serves named sys A. The archive name is s10-system.flar, and it is stored on a remote server named backup_server. On sysA, you create a Solaris 10 branded zone named s10-zone. You want to use the flash archive, located On" /net/bactup_servers/10-system.flar, to install the Operating system in the s10-zone zone. Which command do you choose to install the s10-system.flar archive in the Solaris 10 branded zone (s10-zone)?

Accepted Answer

A

Explanation: The zoneadm command is the primary tool used to install and administer non-global zones. Operations using the zoneadm command must be run from the global zone on the target system. How to Install the solaris10 Branded Zone A configured solaris10 branded zone is installed by using the zoneadm command with the install subcommand. Example: global# zoneadm -z s10-zone install -a /net/machine_name/s10-system.flar –u Reference: System Administration Guide: Oracle Solaris Zones, Oracle Solaris 10 Containers, and Resource Management, Install the solaris10 Branded Zone

Question 15

Your mentor suggests using the dladm rename-link command to rename the network datalinks. What are the two advantages of following this advice?

Accepted Answer

A, E

Explanation: A: To rename the bge0 link to mgmt0, enter the following command: # dladm rename-link bge0 mgmt0 E: Consider that the bge0 device, whose link was named mgmt0 as shown in the previous example, needs to be replaced with a ce0 device because of a hardware failure. The bge0 NIC is physically removed, and replaced with a new ce0 NIC. To associate the newly added ce0 device with the mgmt0 configuration previously associated with bge0, enter the following command: # dladm rename-link ce0 mgmt0 Note: How to Rename a Datalink Use this procedure if you want to change a datalink name to a customized name. For example, some of the datalinks in upgraded system might have retained legacy hardware-based names and you want to change these names to generic ones. Note: dladm rename-link [-R root-dir] link new-link Rename link to new-link. This is used to give a link a meaningful name, or to associate existing link configuration such as link properties of a removed device with a new device.
