IBM IBM Certified System Administrator - AIX V1 C9010-022 Questions & Answers

• Question 191:

  A company has numerous LPARs hosting database servers, and three versions of the DBMS deployed in the environment. A critical APAR fixes data corruption for one version of the database, but it requires a server reboot. The only inventory information available is a spreadsheet with every LPAR's hostname and root password.

  Which sequence of tasks will determine which servers are missing the critical APAR, and only apply it to the servers running the affected level of the database?

  A. Use the spreadsheet to populate the /etc/hosts file on the management node. Configure a NIM server that has the APAR in an lpp_source. Force-register all of the LPARs with the NIM server. Use NIM group operations to install the APAR and boot at a scheduledtime.

  B. Use the spreadsheet to create a dsh node list. Use dsh with Islpp to create a node list for LPARs needing the APAR. Use dcp and dsh to install the APAR and reboot.

  C. Configure a Systems Director server using the spreadsheet import function. Use the inventory function to discover the database level and APAR status. Use the Update Manager to apply the APAR to the affected LPARs and reboot.

  D. Use the spreadsheet to create a dsh node list. Use dcp and dsh to install the APAR. Use dsh to reboot the systems.

  Correct Answer: B

• Question 192:

• Question 195:

  Whiletrying to extend a filesystem /work an administrator receives the following error: 0516- 787 extendlv: Maximum allocation for logical volume fslv00 is 256. What must be done to allow the filesystem to be extended?

  A. Change the filesystem option of maxsz to 512 for the filesystem /work with the command chfs -a maxsz=512 /work.

  B. Change the maximum Logical Partitions to 512forthefslv00 with the command chlv- x512fslv00.

  C. Change the volume groups maximum Logical Partitions per Logical Volume to 512 with thechvg -t 512 vg01.

  D. Change the logical volume type to jfs2 as jfs logical volumes cannot extend passed 256 with the command chfs -v jfs2 -m /work.

  Correct Answer: B

• Question 196:

  The AIX hosts node1 and node2 have Ethernet adapters, both named ent0, configured on the same network. Both are dedicated physical 1GB adapter ports in a Host Ethernet Adapter. Based on this information and the output shown for each node, what is the most likely cause of intermittent failures and slow communication between these adapters?

  

  A. The jumbo_frarnes setting is 'no' and should be set to 'yes'.

  B. The Multi-Core Scaling mode is enabled. Multi-Core Scaling is interfering with communications because the processor is too busy.

  C. The Shared Ethernet Adapter does not have enough bandwidth to accommodate the network traffic.

  D. The media speed is set differently on the adapters than the endpoints on the switch.

  Correct Answer: D

• Question 197:

  B. The administrator created the db2fsloglv log but neglected to format it with the logform command.

  C. The db2fsloglv log was created as a JFS log and a JFS2 log was needed.

  D. There was already another filesystem using the db2fsloglv when the filesystem was created
