• Question 32:

  Additional space is required in /tmp to allowsnapto run to completion. There isNOTenough unallocated space in rootvg to increase /tmp to the required size. ThereISenough free space within a secondary volume group.

  How can the file system configuration be updated to allow snap to run successfully?

  A. Usemirrorvgwith the -I parameter to mirror just /dev/hd3 to the secondary volume group and extend the file system

  B. Create a new logical volume in the secondary volume group, then increase the /tmp file system capacity withextendfs

  C. Create a new file system within the secondary volume group and mount it over /tmp/ibmsupt

  D. Dynamically move /tmp into the secondary volume group withmigratepvand extend the file system capacity withchfs

  Correct Answer: B

• Question 33:

  A customer has been creating LPARs on a new POWER8 system.

  After successfully activating the first 10 LPARs, the customer notices that the available RAM on physical machine reported by the HMC has reduced more than the sum of the memory currently allocated to the activated LPARs.

  The Customer appreciates there will be a memory overhead for each activated LPAR, but the overhead appears more than expected.

  Which LPAR attribute is the likely cause for the excess in memory consumption?

  A. Active memory expansion factor

  B. Maximum Virtual Adapters

  C. Maximum memory

  D. Maximum pages

  Correct Answer: A

• Question 34:

  What is a difference between a Versioned WPAR and a system copy WPAR?

  A. System copy WPARs are created from a mksysb.

  B. Snapshots can be created of a Versioned WPAR.

  C. System copy WPARs are only supported on POWER7+ hardware.

  D. Versioned WPARs are enabled through purchase of an additional licensed product

  Correct Answer: D

• Question 35:

  An administrator needs to replace a failing hard disk, hdisk0, in a mirrored rootvg. After removing the mirror from hdisk0, the administrator cannot remove hdisk0 from the rootvg due to one logical volume still remaining on the failing hard disk, as described below.

  How can this issue be resolved?

  

  A. migratepv hdisk0 hdisk1

  B. migrateiv lg_dumplv hdisk1

  C. mkivcopy lg_dumplv hdisk1

  D. mirrorvg -l lg_dumplv hdisk0 hdisk1

  Correct Answer: A

  B. Increase the logical volume size first by 512 MB.

  C. Add another disk to the exevg volume group and migrate partitions.

  D. Increase the number of logical partitions the logical volume can hold
