Oracle 1Z0-821 Online Questions & Answers

• Question 151:

  Which three statements accurately describe the Automated Installation (AI) client?

  A. If the AI client does not match any criteria to use a custom manifest or script, the default manifest is used.
  B. If the AI client does not match any criteria to use a custom manifest or script, the automated installation aborts.
  C. Any manifest or script in a service can be designated to be the default for that service.
  D. Only the default.xml file is used as the default AT client manifest.
  E. If a client system does not use any SC profile, then an interactive tool opens on that client at first boot after that client installation to complete the configuration of that client.
  F. If a client system does not use any SC profile, then the install server will use the default SC profile.
  A. If the AI client does not match any criteria to use a custom manifest or script, the default manifest is used.
  C. Any manifest or script in a service can be designated to be the default for that service.
  E. If a client system does not use any SC profile, then an interactive tool opens on that client at first boot after that client installation to complete the configuration of that client.

  ---

  Each client uses one and only one AI manifest to complete its installation. The AI manifest is selected for a client according to the following algorithm:

  * If no custom AI manifests are defined for this install service, the default AI manifest is used. The default AI manifest is not associated with any client criteria etc.

  Each client can use any number of system configuration profiles. If a client system does not use any configuration profile, then an interactive tool opens on that client at first boot after that client installation to complete the configuration of that client.

• Question 152:

  Which two options accurately describe the network characteristics of a zone?

  A. DHCP address assignment cannot be configured in a shared IP zone.
  B. Shared IP is the default type of network configuration.
  C. Exclusive IP is the default type of network configuration.
  D. By default, all IP addresses, netmasks, and routes are set by the global zone and cannot be altered in a non global zone.
  E. IPMP cannot be managed within the non-global zone.
  F. Commands such as snoop and dladm cannot be used on datalinks that are in use by a running zone.
  A. DHCP address assignment cannot be configured in a shared IP zone.
  B. Shared IP is the default type of network configuration.

  ---

  A: Non-global zones can not utilize DHCP (neither client nor server). B (not C): By default, non-global zones will be configured with a shared IP functionality. What this means is that IP layer configuration and state is shared between the zone

  you're creating and the global zone. This usually implies both zones being on the same IP subnet for each given NIC.

  Note: A zone is a virtual operating system abstraction that provides a protected environment in which applications run. The applications are protected from each other to provide software fault isolation. To ease the labor of managing multiple

  applications and their environments, they co-exist within one operating system instance, and are usually managed as one entity.

  The original operating environment, before any zones are created, is also called the "global zone" to distinguish it from non-global zones, The global zone is the operating system instance. Incorrect answer:

  E: Exclusive-IP zones can use IPMP. IPMP is configured the same way in an exclusive-IP zone as it is on a system not using zones.

  For shared-IP zones, IPMP can be configured in the global zone.

  F: Full IP-level functionality is available in an exclusive-IP zone.

  An exclusive-IP zone has its own IP-related state.

  An exclusive-IP zone is assigned its own set of data-links using the zonecfg command. The zone is given a data-link name such as xge0, e1000g1, or bge32001, using the physical property of the net resource. The address property of the net

  resource is not set.

  Note that the assigned data-link enables the snoop command to be used.

  The dladm command can be used with the show-linkprop subcommand to show the assignment of data-links to running exclusive-IP zones.

• Question 153:

  You are planning group names for a new system. You decide to use a numbering convention that includes the year and month the project began, to form the group number and name for work associated with that project.

  So, for example, a project targeted to begin in January, 2013 would have the number (name):

  201301(Pr20l301)

  What are the two problems with your plan?

  A. Group names may not contain a numeric character
  B. Group names may be no longer than 7 characters.
  C. Group numbers should not be larger than 60000.
  D. Group names should be all lowercase.
  C. Group numbers should not be larger than 60000.
  D. Group names should be all lowercase.

  ---

  C: The Group ID (GID) field contains the group's numerical ID. GIDs can be assigned whole numbers between 100 and 60000.

  D: Group names contain only lowercase characters and numbers.

• Question 154:

  Which two options describe how to override the default boot behavior of an Oracle Solaris 11 SPARC system to boot the system to the single-user milestone?

  A. from the ok prompt, issue this command: boot -m milestone=single-user
  B. From the ok prompt, issue this command: boot -m milestone/single-user
  C. From the ok prompt, issue this command: boot -milestone=single-user
  D. From the ok prompt. issue this command:boot -s
  E. From from the ok prompt, issue this command:boot -m milestone=s
  A. from the ok prompt, issue this command: boot -m milestone=single-user
  D. From the ok prompt. issue this command:boot -s

  ---

  By default, Solaris will boot to the pseudo milestone "all" and start all services. This behaviour can be changed at boot time using either "-s" to reach single-user, or the new SMF option "-m milestone=XXX" (see kernel(1M) for a list of the

  bootable milestones) to select an explicit milestone.

  Note: boot -s is the same as: boot -m milestone=single-user

  with the difference being that the former is a lot less to type and is what most SysAdmins will be familiar with.

• Question 155:

  To confirm the IP addresses and netmasks have been correctly configured on the network interfaces, which command(s) should you use?

  A. ipadm show-if
  B. ipadm show-nic
  C. ipadm show-addr
  D. ipadm show-addripadm show-mask
  E. ipadm show-ipipadm show-mask
  F. ipadm show-config
  C. ipadm show-addr

  ---

  Show address information, either for the given addrobj or all the address objects configured on the specified interface, including the address objects that are only in the persistent configuration.

  Example: # ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 lo0/v6 static ok ::1/128

• Question 156:

  The following information is displayed about the compress/zjp software package, which Is currently installed on this system: NAME (PUBLISHER)VERSIONIFO Compress/zip3.1.2-0.175.0.0.0.0.537ifNAMEVERSIONDATECOMMENT Compress/zip3.109 Dec 2011 04:50:38 ESTNone Which statement describes the information that is displayed tor the compress/zip software package?

  A. This package cannot be removed.
  B. This package can be updated to a new version when the new version of the package becomes available.
  C. This package cannot be updated.
  D. This package can be updated to version 3.1.3 but not 3.2.
  E. This package cannot be downgraded to version 3.1.1.
  B. This package can be updated to a new version when the new version of the package becomes available.

  ---

  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.

  Note: The "i" in the I column indicates that these packages are installed in this image.

  Adding and Updating Oracle Solaris 11 Software Packages, Showing Package Install State Information

• Question 157:

  How are operating system updates distributed in the Oracle Solaris 11 environment?

  A. 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.
  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. 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. Software updates are published as packages to a repository. All software packages are then updated manually from the command line using the pkg command.

  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.

• Question 158:

  You wish to edit your crontab file that is located in /var/spool/cron/crontab. What command must you enter to edit this file?

  A. crontab -e
  B. crontab -e /var/spool/cron/crontab
  C. crontab -r
  D. crontab -e /etc/default/cron
  A. crontab -e

  ---

  The main tool for setting up cron jobs is the crontab command, though this is not available on every Unix variant. Typically under Solaris or Linux one would create a new crontab or edit an existing one, using the command; crontab -e

  Use the ls -l command to verify the contents of the/var/spool/cron/crontabs file.

• Question 159:

  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?

  A. sys-unconfig
  B. installadm set-criteria
  C. sysconfig create-profile
  D. installadm create-profile
  B. installadm set-criteria

  ---

  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).

• Question 160:

  You are creating a non-global zone on your system.

  Which option assigns a zpool to a non-global zone, and gives the zone administrator permission to create zfs file system in that zpool?

  A. While creating the non-global zone, make the following entry: add deviceset match=/dev/rdsk/c4t0d0endBoot the zone and log in the zone as root. Create the zpool: zpool create pool2 c4t0d0In the non-global zone, root can now create ZFS file system in the pool2 zpool
  B. In the global zone, create the zpool: global# zpool create pool2 c4t1d0While creating the no-global zone, make the following entry: add datasetset name=pool2endadd fsset dir=pool1set special=pool1set type=zfspool1endBoot the zone, log in the zone as root, and create the zfs file system in the pool2 zpool.
  C. In the global zone, create the zpool:global#zpool create pool2 c4t1d0While creating the global zone, make the following entry: add datasetset name=pool2endBoot the zone, log in to the zone as root and create the zfs file systems in the pool2 zpool.
  D. In the global zone, create the zpool and the ZFS file systems that you want to use in the non-global zone: global#zpool create pool2 c4t1d0global#zfs create pool2/dataWhile creating the non-global zone, make the following entry for each ZFS file system that you want to make available in the zone: add fsset dir=/dataset special=pool2/dataset type=zfsend
  E. Create the zpool in the global zone: global#zpool create pool2 c4t1d0Boot the non- global zone, log in to the zone as root, and issue this command to delegate ZFS permissions to root: non-global zone# zfs allow root create , destroy, mount pool2Log in to the non-global zone create ZFS file systems in the pool2 zpool.
  C. In the global zone, create the zpool:global#zpool create pool2 c4t1d0While creating the global zone, make the following entry: add datasetset name=pool2endBoot the zone, log in to the zone as root and create the zfs file systems in the pool2 zpool.
