The IBM XIV Storage System is designed to be cost-efficient in all aspects, while deliveringoutstanding and consistent performance. Which of these features is currently UNAVAILABLE onthe XIV system?（） single-tier architecture supports all kinds of storage in one environment and makes scaling easy 。 built-in thin-provisioning allows the acquisition and installation of additional capacity to bedelayed until needed. 。 innovative use of solid state disk drives offers excellent capacity-for-cost value while meetingenterprise performance standards 。 use of off-the-shelf components makes customized hardware unnecessary and makes itpossible to integrate state-of-the-art hardware assoon as it becomes available.。

A retail customer has an 8-core Power 740 server with 2 partitions. Production has 4 dedicated cores and the test partition has 2 dedicated cores. Both partitions run during the day without problems. At night, batch processing is exceeding the run window. Which solution addresses this problem without requiring additional hardware?（） AddingVMControl will automate processor resource allocation during peak workloads.。 Enable Dynamic Symmetric Multithreading in the HMC to balance workloads across processors.。 Add processing resources during the times they are required using Utility Capacity on Demand.。 Changing the partitions to Uncapped can make use of additional processor cycles during peak workloads.。
In your test database， you have created the ORDERS table as an index-organized table （IOT）. To facilitate faster querying， you have created a mapping table and a bitmap index on the ORDER_FILLED column. You observe that the query performance degrades when users perform a large volume of transactions. While investigating the reason， you find that the mapping table segment is fragmented， leading to poor performance. Which option would you use to defragment the mapping table without affecting the original table data？（） export and import the mapping table。 drop and re-create the mapping table。 truncate the mapping table and reinsert the values。 use the ALTER TABLE···REBUILD command to defragment the mapping table。
