IBM IBM Certifications C9060-528 Questions & Answers

• Question 111:

  The use of deduplication processing in deduplication type storage pools requires more of which IBM Spectrum Protect server resource?

  A. IBM Spectrum Protect server memory

  B. IBM Spectrum Protect client memory

  C. TCP/IP bandwidth between the client and the server

  D. IBM Spectrum Protect client sessions

  Correct Answer: A

• Question 112:

  Which operation runs as part of the PROTECT STGPOOL process?

  A. identification of damaged extents

  B. cleanup of the storage pool

  C. audit of the storage pool

  D. repair of extents marked as damaged

  Correct Answer: D

  As part of the PROTECT STGPOOL operation, processes might run to repair damaged extents in the target server's storage pool. The repair operation occurs under the following conditions:

  1.

  Both the source server and the target server must be at V7.1.5 or later.

  2.

  Extents that are already marked as damaged on the target server are repaired.

  3.

  The repair process does not run an audit process to identify damage.

  4.

  Only target extents that match source extents are repaired. Target extents that are damaged but have no match on the source server are not repaired.

  Note: PROTECT STGPOOL protects a directory-container storage pool.

  Use this command to protect data in a directory-container storage pool by storing a copy of the data in

  another storage pool on a replication target server or on the same server by protecting the data to tape.

  When you protect the directory- container storage pool, you can later try to repair damage in the storage

  pool by using the REPAIR STGPOOL command.

• Question 113:

  What is the default method to back up an IBM Spectrum Protect V8.1 client's file system data?

  A. Image

  B. Full

  C. Incremental

  D. Differential

  Correct Answer: C

  IBM Spectrum Protect uses the progressive incremental backup method. For this backup method, a first full backup of all data objects is created and in subsequent backup operations only changed data is moved to storage.

• Question 114:

  Which two capabilities are provided with the IBM Spectrum Protect incremental forever backup method? (Choose two.)

  A. increase the total number of bytes sent to the protect server

  B. reduce the time needed to perform a restore of a system

  C. reduce the total storage used to save backups of the system

  D. provide the ability to use LAN-Free backups

  E. perform a point-in-time restore

  Correct Answer: BC

  C: The incremental forever backup solution provides these advantages:

  1.

  Reduces the amount of data that goes across the network.

  2.

  Reduces data growth because all incremental backups contain only the blocks that changed since the previous backup.

  3.

  No comparison with the backup target is needed since only changed blocks are identified.

  4.

  Minimizes impact to the client system.

  5.

  Reduces the length of the backup window.

  6.

  No need to schedule an initial full backup as a separate schedule: the first issue of an incremental forever backup automatically defaults to an incremental forever full backup.

  B: In addition, the restore process is optimized, as only the latest versions of blocks that belong to a restored backup are restored. Since the same area on the production disk is recovered only one time, the same block is not written to multiple times. As a result of these advantages, incremental forever is the preferred backup strategy.

• Question 115:

  What are the correct steps for moving the database to new directories?

  A. stop the server, create the new directories, restart the server from the newly created directories

  B. back up database, create new directories, remove the database, and restore the database with option ON

  C. back up database, create new directories, and restore the database with option REPLACE

  D. stop the server, create new directories, move files from old location to the new location, and restart the server

  Correct Answer: B

  DSMSERV RESTORE DB (Restore a database to a point-in-time) command is used to restore a database to a point in time. A volume history file and a device configuration file must be available.

  The option On specifies a file that lists the directories to which the database is restored.

• Question 116:

  What is the purpose of POSTSCHEDULECMD option is the IBM Spectrum Protect backup-archive client option file?

  A. specifies the number of times the schedule needs to be run after a first successful completion

  B. specifies a command that the client program processes after it runs any schedule

  C. specifies any delay in seconds of the scheduled action

  D. specifies the command to run for stopping the scheduler service if it receives an error

  Correct Answer: B

  The postschedulecmd/postnschedulecmd option specifies a command that the client program processes after it runs a schedule. If you want the client program to wait for the command to complete before it continues with other processing, use the postschedulecmd option. If you do not want to wait for the command to complete before the client continues with other processing, specify the postnschedulecmd.

• Question 117:

  Which XML file is generated when the IBM Spectrum Protect client management services is successfully installed?

  A. CMS-client-configuration.xml

  B. TSM-client-configuration.xml

  C. client-configuration.xml

  D. SpectrumProtect-client-configuration.xml

  Correct Answer: C

  You can use the CmsConfig discover command to automatically discover options files and log files, and add them to the client configuration file, client-configuration.xml. In this way, you can help to ensure that the client management service can access the client log files and make them available for diagnosis in the Operations Center.

• Question 118:

  Which file is used to add a system-wide client option on an IBM Spectrum Protect client in a Windows environment?

  A. dsmsys.opt

  B. dsm.sys

  C. dsmopt.sys

  D. dsm.opt

  Correct Answer: D

  Use the SET SUBFILE (Set subfile backup for client nodes) command to set up the server to allow clients to back up subfiles. On the client's workstation, the SUBFILECACHEPATH and SUBFILECACHESIZE options must be specified in the client's options file (dsm.opt). If you are using a Windows client, you must also specify the SUBFILEBACKUP option.

  References: IBM Spectrum Protect for Windows Version 8.1.0, Administrator's Reference, p 1279

• Question 119:

  How is the amount of client data backed up during the last 24 hours determined?

  A. run QUERY SUMMARY BEGIND= ? administrative command

  B. use the command line builder within the Operations Center and run Q BACKUP BEGIND=1

  C. look at the Activity pane the IBM Spectrum Protect Operations Center

  D. from the administrative command line run QUERY OCCUPANCY -ALL

  Correct Answer: D

  QUERY OCCUPANCY (Query client file spaces in storage pools)

  Use this command to show where client file spaces are stored and how much space they occupy.

  Incorrect Answers:

  B: The query backup command displays a list of backup versions of your files that are stored on the IBM Spectrum Protect server, or that are inside a backup set from the server when the backupsetname option is specified.

• Question 120:

  Which backup-archive client host operating system requires the use of a dsm.sys file?

  A. UNIX/Linux

  B. Microsoft Windows workstation system

  C. any server in a Microsoft Windows cluster D. Microsoft Windows server 2008

  Correct Answer: A

  Configure the IBM Spectrum Protect client

  After installing the backup-archive client, you must configure it before performing any operations.

  The following applies to AIX, Linux, Solaris, and Mac OS X.

  If you are upgrading the backup-archive client, it is unnecessary to reconfigure the scheduler, web client,

  or other configuration settings. If the dsm.opt and dsm.sys files used by the previous client installation are

  available in the default installation directory or the directory or file pointed to by the DSM_CONFIG and

  DSM_DIR environment variables, the client accesses these files for configuration information.
