  To simplify administration of a network, the decision was made to use bridging rather than routing Your network includes three Oracle Solaris 11 systems,

  en-tiny cib uiiuyo yiuviumy reuunuaiu pauiways.

  You previously created the bridges on each system with the following commands:

  SystemA#dladmcreate-bridge-1 netl -1 net2 bridgeA

  SystemB # dladm create-bridge -1 netl -1 net2 bndgeB

  SystemC # dladm create-bridge -1 netl -1 net2 bndgeC

  You notice that network performance is less than expected, and packets between networks X and Z are being forwarded by bridgeA and bridgeB, rather than being forwarded directly by bndgeC.

  Select the solution

  A. SystemC # dladm modify-bndge -p stp bridgeC
  B. SystemA # dladm modify-bridge -p stp bridgeA SystemB # dladm modify-bridge -p stp bndgeB SystemC # dladm modify-bridge -p stp bridgeC
  C. SystemC # dladm modify-bridge -p trill bridgeC
  D. SystemA # dladm modify-bridge -p trill bridgeA SystemB # dladm modify-bridge -p trill bndgeB SystemC # dladm modify-bridge -p trill bndgeC
  E. SystemC # ipadm set-prop -p forwarding=on bridgeC
  F. SystemC # dladm set-linkprop -p promiscuous=on bridgeC
  E. SystemC # ipadm set-prop -p forwarding=on bridgeC

• Question 63:

  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
  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

  ---

  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.

• Question 64:

  A process associated with a user application keeps crashing on the user, but a core dump is not being saved in the /var/core/pprocess directory. The core dump configuration is: global core file pattern: /var/core/core. %f.%p global core file content: default init core file pattern: core init core file content: default global core dumps: enabled per-process core dumps: enabled global setid core dumps disabled per-process setid core dumps: disabled global core dump logging: disabled Which option would change the core dump configuration so that a user's per-process core dumps get saved in the /var/core/pprocess directory?

  A. coreadm --g /var/core/pprocess/core.%f %p
  B. coreadm --i /var/core/pprocess/core.%f.%p
  C. coreadm --i /var/core/pprocess/core.%f.%p coreadm --e proc--setid --d process
  D. coreadm --g /var/core/pprocess/core.%f.%p coreadm --e global--setid
  E. Make this change to the /etc/coreadm conf file: init core file pattern: /var/core/pprocess/core.%f.%p
  E. Make this change to the /etc/coreadm conf file: init core file pattern: /var/core/pprocess/core.%f.%p

• Question 65:

  Select two statements that correctly describe the capabilities of the Distribution Constructor.

  A. ISO images for use with the Automated Installer (AI) can be created.
  B. Bootable USB images can be created for SPARC and x86 architectures.
  C. A single installation server can be used to create ISO images for SPARC and x86 architectures.
  D. Checkpoints can be used to pause the build, allowing scripts to run that modify the resulting ISO Image.
  E. A single Installation server can be used to create ISO images for Solaris 10 and Solaris11 operating systems.
  A. ISO images for use with the Automated Installer (AI) can be created.
  D. Checkpoints can be used to pause the build, allowing scripts to run that modify the resulting ISO Image.

  ---

  A: You can use the distribution constructor to create the following types of Oracle Solaris images:

  *

  (A) x86 or SPARC ISO Image for Automated Installations

  *

  Oracle Solaris x86 live CD image

  *

  x86 or SPARC Oracle Solaris text installer image

  *

  x86 Oracle Solaris Virtual Machine

  Note: You can use the distribution constructor to build custom Oracle Solaris images. Then, you can use the images to install the Oracle Solaris software on individual systems or multiple systems. You can, also, use the distribution constructor to create Virtual Machine (VM) images that run the Oracle Solaris operating system.

  D: Checkpointing Options You can use the options provided in the distro_const command to stop and restart the build process at various stages in the image-generation process, in order to check and debug the image that is being built. This process of stopping and restarting during the build process is called checkpointing.
