• Question 11:

  ServerA contains two ISO images of a package repository, named sol.repo.iso-a and sol.repo.iso-b respectively.

• Question 13:

  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?

  A. cat so1.repo.iso-a sol.repo.iso-b > so1.full.iso Mount 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

  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

  C. cat so1.repo.iso-a so1.repo.iso-b > so1.full.iso Mount the ISO image and use the rsync command to extract the contents of the ISO file to /export/IPS/ repo 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 solaris \ -g http://pkg.oracle.com/

  D. cat so1.repo,iso-a so1.repo.iso-b > /export/IPS/repo.iso Mount the ISO image and copy the repo directory 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 - G http://serverA.example.com/ \

  -g http://pkg.oracle.com/solaris.com/release/- p solaris

  Correct Answer: D

  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.

  D. storage-nas

  Correct Answer: A

  Explanation: How to Create an iSCSI LUN The disk volume provided by the server is referred to as the target. When the LUN is associated with an iSCSI target, it can be accessed by an iSCSI initiator. The following tasks are completed on the system that is providing the storage device.

  1. Install the COMSTAR storage server software.

  target# pkg install storage-server

• Question 20:

  View the Exhibit to inspect the file system configuration on your server.

  

  Your department'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?

  A. On Saturday: zfs snapshot pool1/data@sat zfs send pool1/data@sat > /remote/backup/full

  B. On Saturday: zfs create snapshotpool1/data@sat zfs send pool1/data@sat | zfs recv remote/backup/ `date' `+%m%d%y'

  C. On Saturday: zfs create snapshotpool1/data@sat zfs send pool1/data@sat > /remote/backup/full

  D. 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 > zfs recv newtank/dana This shortcut syntax is equivalent to the incremental syntax in the preceding example.
