Question 3 Single choice

ServerA contains two ISO images of a package repository named so1.repo.iso-a and so1.repo.iso-b respectively. You need to create a single local package repository on server that clients can connect to.
The package repository will be stored on the /export/IPS file system and named repo. The preferred publisher will be named solaris and the publisher URL will be http://serverA.example.com.

Which is the correct procedure to perform on ServerA to create the local Package repository?

  1. A

    cat so1.repo.iso-a sol.repo.iso-b > so1.full.isoMount the ISO image and use the rsync command to extract the contents of the ISO file to the /export/IPS file system.Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true.Set the preferred publisher by using pkg set-publisher -G http://pkg.oracle.com/solaris/release/ \-g http"//serverA.example.com/ solaris

  2. B

    cat so1.repo.iso-a so1.repo.iso-b > /export/IPS/repo Set the pkg/inst_root property to true and the pkg/readonly property to /export/IPS Set the preferred publisher by using pkg set-publisher -G http://serverA.example.com/ \ -g http://pkg/oracle.com/solaris/rekease/solaris

  3. C

    cat so1.repo.iso-a so1.repo.iso-b > so1.full.isoMount the ISO image and use the rsync command to extract the contents of the ISO file to /export/IPS/ repoSet the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true Set the preferred publisher by using pkg set-publisher solaris \ -g http://pkg.oracle.com/

  4. D

    cat so1.repo,iso-a so1.repo.iso-b > /export/IPS/repo.iso Mount the ISO image and copy the repodirectory from the ISO image to /export/IPS/repo set the pkg/inst_root property and the pkg/readonly property to /export/IPS/repo set the preferred pkg/inst_root property by using pkg set-publisher - Ghttp://serverA.example.com/ \- g http://pkg.oracle.com/solaris.com/release/- p solaris

Show answer and explanation

Correct answer: D

Explanation

Explanation: Concatenate the files into one file using the cat command. Make the contents of the repository .iso file available using the mount command. To increase the performance of repository accesses and to avoid the need to remount the .iso image each time the system restarts, copy the repository files from /mnt/repo/to a ZFS file system. You can do this copy with rsync or with tar.

Question 4 Multiple choice

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

  1. A

    Create a local IPS repository on the AI Install server and start the repository server service, the publisher origin to the repository file.

  2. B

    Set up a IP address on the AI install server.

  3. C

    The DHCP server must be enabled on the install server and must provide the DHCP service for the clients.

  4. D

    DHCP must be available on the network for the Install server and the clients, but the install server does not need to be the DHCP server.

  5. E

    Download the AI boot image. The image must be the same version as the Oracle Solaris OS that you plan to install on the client.

  6. F

    Download the text install image into the IPS repository.

  7. G

    Install the AI installation tools.

  8. H

    Create the AI install service. Specify the path to the AI network boot image ISO file and the path where the AI net image ISO file should be unpacked.

  9. I

    Create the AI install service. Specify the path to the AI network boot image ISO file and the path to the
    IPS repository.

Show answer and explanation

Correct answers: B, D, F, G, I

Explanation

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.

    if the A! client does not match any criteria to use a custom manifest or script, the automated installation aborts.

  3. C

    Any manifest or script in a service can be designated to be the default for that service.

  4. D

    Only the default.xml file is used as the default Al client manifest.

  5. 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.

  6. F

    If a client system does not use any SC profile, then the install server will use the default SC profile.

Pool2

c3t4d0

c3t5d0

The ZFS configuration on serverB is: Pool1

mirror-0

c3t2d0

c3t3d0

mirror-1

c3t4d0

c3t5d0

You need to change serverA's ZFS configuration to match serverB's configuration.

Which option should you choose to modify the configuration on serverA so that it matches serverB's configuration?

  1. A

    zpool destroy pool2
    zpool attach pool1 c3t4d0 ct3t5d0

  2. B

    zpool destroy pool2
    zpool attach pool1 c3t2d0 c3t2d0 c3t4d0 c3t5d

  4. D

    zpool destroy pool2
    zpool mirror pool1 pool2

  5. E

    zpool destroy pool2
    zpool attach pool1 c3t2d0 c3t4d0
    zpool attach pool1 c3t3d0 c3t5d0

  6. F

    zpool destroy pool1
    zpool destroy pool2
    zpool create pool1 mirror c3t2d0 c3t3d0 c3t4d0 c3t5d0

Show answer and explanation

Correct answer: F

Explanation

Explanation: We destroy both pools. Then we recreate the mirror.

Note:
zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.

Question 9 Single choice

The core dump configuration for your system is:

A user is running a process in the global zone and the process crashes. The process information is:

User1 2663 2618 0 17:46:42 pts/2 0:00 /usr/bin/bash

The server host name is: zeus

What will the per-process core file be named?

  1. A

    core.bash.2663.global

  2. B

    core.bash.2663.zeus

  3. C

    /var/core/core.bash.2663

  4. D

    /var/core/core.bash.2663.global

Show answer and explanation

Correct answer: C

Explanation

Explanation: Note the first line:
global core file pattern: /globalcore/core.%f.%p

The program name is bash
The runtime process ID is 2663

Note: By default, the global core dump is disabled. You need to use the coreadm command with the -e global option to enable it. The -g option causes the command to append the program name(%f) and the runtime process ID (%p) to the core file name.

1. Install the COMSTAR storage server software.
target# pkg install storage-server
Etc.
