• Question 111:

  You are using AI to install a new system. You have added to following information to the AI manifest:

  source = "http://sysA.example.com/zone_cfg/zone.cfg"/>

  Which statement is true with regard to the zone.cfg?

  A. The zone.cfg file is text file in a zonecfg export format.
  B. The zone.cfg file is an AI manifest that specifies how the zone is to be installed.
  C. The zone.cfg file is an xml file in a form suitable for use as a command file for the zonecfg command.
  D. The zone.cfg file is an SC profile with keywords that are specific for configuring a as part of the installation process.
  E. It is am xml configuration file from the /etc/zone directory. It will be used as a profile for the zone. It specifies the zonename, zonepath, and other zonecfg parameters.
  B. The zone.cfg file is an AI manifest that specifies how the zone is to be installed.

  ---

  The configuration element supports non-global zone configurations. When installing a global zone system, the zone configurations specified in the AI manifest are used to install non-global zones onto the system after the global zone has

  been installed

  The configuration element has the following attributes:

  type

  The type of configuration to install. The only type supported by AI is zone.

  name

  A name given to the configuration. This name must be unique across all configuration elements in an AI manifest. For configurations of type zone, this name is also used as the zonename for the zone.

  source

  The location from which AI downloads the configuration file for this configuration element. The value can be an HTTP or FILE URI specification. For configurations of type zone, this value should point to a zone configuration file as produced

  from the zonecfg export command.

• Question 112:

  When you issue the "gzip: zommand not found" message is displayed. You need to install the gzip utility on your system. Which command would you use to check if the gzip utility is available from the default publisher for installation?

  A. pkg info|grep gzip
  B. pkg list SUNWgzip
  C. pkg contents gzip
  D. pkg search gzip
  D. pkg search gzip

  ---

  Searching for Packages

  Use the pkg search command to search for packages whose data matches the specified pattern.

  Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search command returns the names of packages that match the query.

  pkg search

  search [-HIaflpr] [-o attribute ...] [-s repo_uri] query Search for matches to the query, and display the results. Which tokens are indexed are action-dependent, but may include content hashes and pathnames.

  Note: pkg is the retrieval client for the image packaging system. With a valid configuration, pkg can be invoked to create locations for packages to be installed, called 'images', and install packages into those images. Packages are published

  by publishers, who may make their packages available at one or more repositories. pkg, then, retrieves packages from a publisher's repository and installs them into an image.

• Question 113:

  The rctladm command reports the following:

  # rctladm |grep task.max.lwps task.max-lwps syslog=notice [ count 1

  Which of the following correctly describes the system configuration?

  A. A message will be logged with syslogd when the number of notice messages generated by the resource control threshold meets or exceeds the value specified with [count]
  B. A message will be logged with sysloqd when the number of violations generated by the resource control threshold meets or exceeds the value specified with [count].
  C. The global resource control monitoring for the task.max-lwps resource control has been enabled and syslog messaging for that resource control has been set to notice. However, because the [count] value has not been specified, there is no threshold set for the resource to monitor. The configuration to monitor the task.max-lwps resource control is incomplete.
  D. The global resource control monitoring for the task.max-lwps resource control has been enabled, syslog messaging for that resource control has been set to notice.
  D. The global resource control monitoring for the task.max-lwps resource control has been enabled, syslog messaging for that resource control has been set to notice.

• Question 114:

  Before booting testzone. 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.

  A. zoneadm -C testzone
  B. zoneadm -console testzone
  C. zlogin -z testzone console C
  D. zlogin -z testzone -C
  E. zlogin -C testzone F zoneadm -z testzone -C
  E. zlogin -C testzone F zoneadm -z testzone -C

• Question 115:

  The ZFS configuration on your server is:

  Pool1 6.67G31K/pool

  Pool1/data31K31K/data

  Select the three commands that you would use to 1. Create, 2. List, and 3. Delete a snapshot of the /data file system.

  A. zfs snapshot pool1/data@now
  B. zfs create snapshot pool1/data@now
  C. zfs list -t snapshot
  D. zfs list -t snapshot pool1/data
  E. zfs destroy pool1/data@now
  F. zfs destroy snapshot pool1/data@now
  A. zfs snapshot pool1/data@now
  D. zfs list -t snapshot pool1/data
  E. zfs destroy pool1/data@now

  ---

  A: Snapshots are created by using the zfs snapshot command, which takes as its only argument the name of the snapshot to create.

  D: You can list snapshots as follows: # zfs list -t snapshot

  E: Snapshots are destroyed by using the zfs destroy command. For example: # zfs destroy tank/home/ahrens@now

• Question 116:

  A non-global zone named testzone is currently running.

  Which option would you choose to dynamically set the CPU shares for the zone to two shares?

  A. While logged in to the global zone, enter: prctl -n zone.cpu-shares -v 2 -r -i zone testzone
  B. While logged in to the global zone, enter: zonecfg -z testzone add rctl set name=zone cpu-shares setvalue=(priv=privilegedJimit=2,action=none)
  C. While logged in to the global zone, enter: prctl -n 2 zone cpu-shares -i zone testzone
  D. While logged in to the global zone, enter: zonecfg -z testzone add rctl set name-zone cpu-shares set value=2
  E. While logged in to testzone, enter: prctl -n zone.cpu-shares -v 2 -r -i zone testzone
  D. While logged in to the global zone, enter: zonecfg -z testzone add rctl set name-zone cpu-shares set value=2

• Question 117:

  On server A, you enter the following command to add a static route to serverA

  route -p add -host 192.168.1.101 192.168.1.101 -static

  What is the purpose of this command?

  A. to temporarily bypass IP Filter rules
  B. to specify an IPMP target IP address to in.mpathd
  C. to specify routing to an adjacent network when in.rdisc is not used
  D. to specify routing to an adjacent network when in.routed is not used
  E. to ensure the IP address for serverB is not flushed from the ARP cache
  F. to optimize link aggregation using a direct connection between two systems
  B. to specify an IPMP target IP address to in.mpathd

  ---

  Note: # route -p add -host destination-IP gateway-IP -static where destination-IP and gateway-IP are IPv4 addresses of the host to be used as a target.

  For example, you would type the following to specify the target system 192.168.10.137, which is on the same subnet as the interfaces in IPMP group itops0:

  $ route -p add -host 192.168.10.137 192.168.10.137 -static This new route will be automatically configured every time the system is restarted. If you want to define only a temporary route to a target system for probe-based failure detection, then do not use the -p option.

• Question 118:

  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.
  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.

  ---

  A: 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.

  D: When you create a new install service,

  install_service_image_path/auto_install/manifest/default.xml is the initial default AI manifest for that install service.

  E: 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 119:

  The crash dump notification on your server is:

  

  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?

  A. savecore -f vmdump.0
  B. dumpadm uncompressed
  C. gunzip vmdump.0
  D. dumpadm -z off
  A. savecore -f vmdump.0

  ---

  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 useful if the information stored on the dump device has been copied to an on-disk file by means of the dd(1M) command.

• Question 120:

  You display the IP Interface information with ipmpstat - i

  Which two characteristics are indicated by characters that may be included in the FLAGS column?

  A. default route
  B. IP forwarding enabled
  C. allocated to global zone
  D. unusable due to being inactive
  E. nominated to send/receive IPv4 multicast for its IPMP group
  D. unusable due to being inactive
  E. nominated to send/receive IPv4 multicast for its IPMP group

  ---

  The ipmpstat command concisely displays information about the IPMP subsystem. It supports five different output modes, each of which provides a different view of the IPMP subsystem (address, group, interface, probe, and target),

  described below.

  -i

  Display IP interface information ("interface" output mode).

  Interface Mode

  Interface mode displays the state of all IP interfaces that are tracked by in.mpathd on the system. The following output field is one of the supported:

  FLAGS

  Assorted information about the IP interface:

  i

  (D)

  Unusable due to being INACTIVE.

  s

  Marked STANDBY.

  m

  (E)

  Nominated to send/receive IPv4 multicast for its IPMP group.

  b

  Nominated to send/receive IPv4 broadcast for its IPMP group.

  M

  Nominated to send/receive IPv6 multicast for its IPMP group.

  d

  Unusable due to being down.

  h

  Unusable due to being brought OFFLINE by in.mpathd because of a duplicate hardware address.
