Oracle Solaris 11 Advanced System Administration

Question No: 11

Which four configuration elements are managed by the dumpadm utility?

  1. the location of the dump device

  2. the location of the savecore directory

  3. the index number for the next core dump

  4. the reserved file system space that a core dump may not use

  5. the compression of the crash dump file

  6. the size of the dump device

Answer: A,B,D,E

Explanation: dumpadm – configure operating system crash dump


/usr/sbin/dumpadm [-nuy] [-c content-type] [-d dump-device] [-m mink | minm | min%] [-s savecore-dir]

[-r root-dir] [-z on | off] The options include:

A: -d dump-device

Modify the dump configuration to use the specified dump device. B: -s savecore-dir

Modify the dump configuration to use the specified directory to save files written by savecore.

D: -m mink | minm | min%

Create a minfree file in the current savecore directory indicating that savecore should maintain at least the specified amount of free space in the file system where the savecore directory is located.

E: -z on | off

Modify the dump configuration to control the operation of savecore on reboot. The options are on, to enable saving core files in a compressed format, and off, to automatically uncompress the crash dump file. The default is on, because crash dump files can be very large and require less file system space if saved in a compressed format.

Question No: 12

Which option provides limits for physical, swap, and locked memory?

  1. rcap.max-rss

  2. zone.max-locked-memory

  3. capped-memory

  4. zone.max-memory

Answer: C

Explanation: The capped-memory resource sets limits for physical, swap, and locked memory. Each limit is optional, but at least one must be set.

Question No: 13

Which utility/service must you use to set processes with FSS by default?

  1. priocntl

  2. svc:/system/scheduler:default

  3. dispadmin

  4. projmod

Answer: C

Explanation: Set the default scheduler for the system to be the FSS.

# dispadmin -d FSS

Question No: 14

Which two statements regarding the pkg command are correct?

  1. It requires HTTP to connect to a remote repository.

  2. It uses the set-publisher subcommand to remove an origin.

  3. It cannot point to both sticky and nonsticky publishers in the same repository.

  4. It uses the unset-publisher subcommand to remove publishers.

  5. It uses the set-publisher subcommand to remove publishers.

Answer: A,B

Explanation: A: Configure pkg.depotd to provide remote access. pkg.depotd provides an HTTP interface to a pkg repo. Here we are going to make the repo server listen on port 10000, and use the repo dir we created as its default.

# svcadm disable pkg/server

# svccfg -s pkg/server setprop pkg/inst_root = /data/myrepo

# svccfg -s pkg/server setprop pkg/port = 10000

# svcadm refresh pkg/server

# svcadm enable pkg/server

B: Set-Publisher

With -G (-remove-origin), remove the URI or path from the list of origins for the given publisher. The special value * can be used to remove all origins.


Not D: unset-publisher publisher …

Remove the configuration associated with the given publisher or publisher

Not E: set-publisher

Update an existing publisher or add a package publisher. If no options affecting search order are specified, new publishers are appended to the search order and are thus searched last.

Question No: 15

The zpool configuration on serverA is:

pool 1 c3t2d0 c3t3d0 pool 2 c3t4d0


The zpool configuration on servetB is: pool1

mirror-0 c3t2d0 c3t3d0 mirror-1 c3t4d0 c3t5d0

Which option will modify the configuration on serverA to match serverB?

  1. zpool destroy pool2zpool attach pool1 c3t4d0 c3t5d0

  2. zpool destroy pool2zpool attach pool1 c3t2d0 c3t2d0 c3t4d0 c3t5d0

  3. zpool destroy pool2zpool add pool1 c3t4d0 c3t5d0

  4. zpool destroy pool2zpool mirror pool1 pool2

  5. zpool destroy pool2zpool attach pool1 c3t2d0 attach pool1 c3t3d0zpool attach pool1 c3t4d0 attach pool1 c3t5d0

  6. zpool destroy pool1; zpool destroy pool2; zpool create pool1 mirror c3t2d0 c3t3d0 mirror c4t4d0 c3t5d0

Answer: F

Explanation: Example;root@solaris:~# zpool create pool1 mirror c8t0d0 c8t1d0 mirror c8t3d0 c8t4d0

root@solaris:~# zpool status pool: pool1

state: ONLINE

scan: none requested config:


mirror-0 ONLINE 0 0 0

c8t0d0 ONLINE 0 0 0

c8t1d0 ONLINE 0 0 0

mirror-1 ONLINE 0 0 0

c8t3d0 ONLINE 0 0 0

Question No: 16

Consider the following commands on a newly installed system:

zfs set compression=on rpool

zfs get -H -o source compression rpool What is the output of the second command?

  1. default

  2. local

  3. on

Answer: C

Explanation: The zfs get command supports the -H and -o options, which are designed for scripting. You can use the -H option to omit header information and to replace white space with the Tab character. Uniform white space allows for easily parseable data. You can use the -o option to customize the output in the following ways:

  • The literal name can be used with a comma-separated list of properties as defined in the Introducing ZFS Properties section.

  • A comma-separated list of literal fields, name, value, property, and source, to be output followed by a space and an argument, which is a comma-separated list of properties.

  • The following example shows how to retrieve a single value by using the -H and -o options of zfs get:

    # zfs get -H -o value compression tank/home on

    Question No: 17

    To reduce the use at storage space on your server, you want to eliminate duplicate copies of data in your server#39;s ZFS file systems. How do you specify that pool1/data should not contain duplicate data blocks on write operations?

    1. zfs create -o compression=on pool1/data

    2. zpool create -o deduplication=on pool1 ; zfs create pool1/data

    3. zpool create -o dedupratio=on pool1 ; zfs create pool1/data

    4. zfs create -o dedupratio=2 pool1/data

    5. zfs create -o dedup=on pool1/data

    Answer: E

    Explanation: To c reate a file system with deduplication: root@solaris:~# zfs create -o dedup=on

    Note: If you have a storage pool named #39;tank#39; and you want to use dedup, just type this: zfs set dedup=on tank

    Question No: 18

    At which two stages are backups of the service configuration repository made?

    1. during boot, after the early-manifest-import service finishes

    2. during boot, before the manifest-import service starts

    3. during manifest import, before the manifest-import service finishes

    4. during manifest import, after the manifest-import service finishes

    5. when a service is modified using the svccfg command

    6. after the last successful boot

    7. when the svcadm refresh command is executed

    Answer: B,D

    Explanation: http://illumos.org/msg/SMF-8000-MY

    Question No: 19

    Which two zpool subcommands will permanently remove a submirror from active storage pool?

    1. remove

    2. detach

    3. destroy

    4. offline

    5. replace

    6. split

    7. zpool does not permit this operation on an active storage pool unless the submirror faults.

    Answer: A,B Explanation:

    zpool detach pool device

    Detaches device from a mirror. The operation is refused if there are no other valid replicas of the data.

    Question No: 20

    You must configure your server to use IPMP with probe based failure detection enabled. Which statement is a valid constraint or feature that applies to this requirement?

    1. Link-based detection is supported only on Generic Lan Driver version 2 (GLDv2)- complaint NICs.

    2. GLDv2 NICs are not supported in Oracle Solaris 11.

    3. GLDv3 NICs configured for link based detection by default.

    4. You must first disable link based detection before configuring probe-based failure


    Answer: C

    Explanation: Network drivers that support link-based failure detection monitor the interface#39;s link state and notify the networking subsystem when that link state changes.


    Not B: GLDv2 is a multi-threaded, clonable, loadable kernel module that provides support to device drivers for local area networks. Local area network (LAN) device drivers in the Solaris OS are STREAMS-based drivers that use the Data Link Provider Interface (DLPI) to communicate with network protocol stacks.

    Not D: Link-based failure detection is always enabled, provided that the interface supports this type of failure detection.

    You cannot disable link-based failure detection if this method is supported by the NIC driver.
