Question No.52

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: PUBLISHERTYPESTATUSURI

solarisoriginonlinehttp://pkg.oracle.com/solaris/release/ You will be replacing the current publisher with: PUBLISHERTYPESTATUSURI

solarisoriginonlinehttp://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?

  1. Perform an rsync on the ISO image to copy the files from the ISO image to the /export/IPS file system.

  2. chmod 700 on/export/IPS

  3. Use the svccfg command to set the pkg/inst_root property to export/IPS.

  4. Use the svccfg command to set the pkg.inst_root property to /export/IPS.

  5. Use the svccfg command to set the pkg/readonly property to the application/pkg/server service to true.

  6. Use the svccfg command to set the pkg/readonly property for the application/pkg/server service false.

  7. Refresh the application/pkg/server service with the svcadm refresh command.

  8. Refresh the package repository with the pkgrep refresh command.

  9. Enable the application /pkg/server service.

  10. Run the pkhrepo rebuild command to rebuild the repository catalog.

Correct Answer: ABDEGI

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.

  1. (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:

  2. Once the files are copied, unmount the image and deallocate the block device.

  3. 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

  4. Start the pkg.depotd repository service:

(G) # svcadm refresh application/pkg/server

(I) # svcadm enable application/pkg/server Reference:

Your department#39;s backup policy is to perform a full backup to remote system disk on Saturday. On each weekday, you are to perform an incremental backup to the same remote system disk.

Each incremental backup will contain only data that has been modified since the previous Saturday backup.

The server file systems must remain available at all times and can never be taken offline. The backup must not only provide for the recovery of the most recent version of a file, but must also allow recovery of previous versions of a file.

Following your company policy, which two describe the correct procedure to be performed on Saturday for backing tip the /data file system to a remote disk named /remote/backup?

  1. On Saturday:

    zfs snapshot pool1/data@sat

    zfs send pool1/data@sat gt; /remote/backup/full

  2. On Saturday:

    zfs create snapshotpool1/data@sat

    zfs send pool1/data@sat | zfs recv remote/backup/ `date#39; ` %m%d%y#39;

  3. On Saturday:

    zfs create snapshotpool1/data@sat

    zfs send pool1/data@sat gt; /remote/backup/full

  4. On Saturday:

zfs create snapshotpool1/data@sat

zfs send pool1/data@sat | zfsrecv remote/backup

Correct Answer: BC

Explanation:

You can use the zfs send command to send a copy of a snapshot stream and receive the snapshot stream in another pool on the same system or in another pool on a different system that is used to store backup data.

You can send incremental data by using the zfs send -i option. For example:

host1# zfs send -i tank/dana@snap1 tank/dana@snap2 | zfs recv newtank/dana Note that the first argument (snap1) is the earlier snapshot and the second argument (snap2) is the later snapshot. In this case, the newtank/dana file system must already exist for the incremental receive to be successful.

The incremental snap1 source can be specified as the last component of the snapshot name. This shortcut means you only have to specify the name after the @ sign for snap1, which is assumed to be from the same file system as snap2. For example:

host1# zfs send -i snap1 tank/dana@snap2 gt; zfs recv newtank/dana This shortcut syntax is equivalent to the incremental syntax in the preceding example.

Question No.56

alice is a user account used by Alice on a Solaris 11 system. sadmin is a role account on the same system.

Your task is to add the command /usr/sbin/cryptoadm to the Network management profile, so that Alice can execute it, while assuming the sadmin role.

Select the three activities necessary to accomplish this.

  1. To the file /etc/security/prof_attr, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

  2. To the file /etc/security/auth_attr, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

  3. To the file /etc/security/exec_attr.d/local-entriies, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

  4. Run the roles alice to ensure that alice may assume the role sadmin.

  5. Run the command profiles sadmin to ensure that the role sadmin includes the network Management profile.

  6. Run the command profiles alice to ensure that the Alice has permissions to access the Network management profile.

  7. Run the command profiles quot;Network managementquot; to ensure that the Network management profile includes the sadmin role.

Correct Answer: CDG

Explanation:

C: /etc/security/exec_attr is a local database that specifies the execution attributes associated with profiles. The exec_attr file can be used with other sources for execution profiles, including the exec_attr NIS map and NIS table.

A profile is a logical grouping of authorizations and com- mands that is interpreted by a profile shell to form a secure execution environment.

Reference: man exec_attr

Question No.57

The core dump configuration for your system is:

image

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. core.bash.2663.global

  2. core.bash.2663.zeus

  3. /var/core/core.bash.2663

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

Correct Answer: C

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.

Question No.58

You have set up the task.max-lwps resource control on your Solaris 11 system. Which option describes how to configure the system so that syslogd notifies you when the resources control threshold value for the task.max-lwps resource has been exceeded?

  1. Use the rctladm command to enable the global action on the task.max-lwpa resource control.

  2. Modify the /etc/syslog.conf file to activate system logging of all violations of task.max- lwps and then refresh then svc: /system/system-log:default service.

  3. Activate system logging of all violations of task.max-lwpp in the /etc/rctldm.conf file and then execute the rctladm-u command.

  4. Use the prct1 command to set the logging of all resource control violations at the time the task.max-lwps resource control is being setup.

  5. Use the setrct1 command to set the logging of all resource control violations for the task.max-lwps resource control.

Correct Answer: A

Explanation:

rctladm – display and/or modify global state of system resource controls

The following command activates system logging of all viola- tions of task.max-lwps.

# rctladm -e syslog task.max-lwps
