A company installed a new server to manage its electronic image storage. They have two distinct image sizes： 2KB and 16KB. Two distinct arrays are created on a ServeRAID adapter. The first array will store all of the 2KB images， and the second array will store all the 16KB images. The RAID stripe size was left at the default size of 8KB. After installation， a performance problem is identified. According to performance monitoring， 80% of the images are 16KB. Which of the following will best optimize performance？（） ["Change the stripe size on the RAID controller","Change the stripe size to 1024K on the RAID controller","Change the stripe size on the RAID controller for the first array","Change the stripe size on the RAID controller for the second array"]

In a scale-out environment，what is a benefit of running DB2 pureScale compared to other solutions？（） ["Provides a highly available cluster of Power Systems enabling near linear scalability and disaster recovery across different sites.","Incorporates a hardware locking mechanism which resembles the Parallel Sysplex on the mainframe， delivering performance and scalability.","Enables near linear scalability by partitioning and clustering the database across multiple nodes， and adding nodes dynamically when needed.","Provides scalability by employing a highly available cluster of servers interconnected by an Infiniband network and a central locking mechanism."]
【背景资料】某5层砖混结构宿舍楼，7度抗震设防。墙厚240mm，墙长48m，宽12m，实际地质情况为西部地基土为中偏高压缩性土，而东部较坚硬。因紧邻该建筑的东侧建有同类型的房屋，并具有详细的地质勘察资料，故建设方省去了地质勘察，要求设计院按该地质勘察资料确定地基承载力。在房屋报建时因无地质资料，未获审批，后不得不补做了勘察，但此时基础已施工完成。施工方为了赶工期，新招进一劳务作业队伍进行墙体砌筑，发现砌筑砂浆层饱满度为75%，皮数砖同缝，多处转角和纵横墙丁字相交处的施工临时洞口处留直槎等情况，当房屋建至5层，墙面开始出现少量细微裂纹，随后逐步发展为裂缝，且不断增多。
请根据上述背景资料完成以下选项。
西部地基土为中偏高压缩性土，而东部较坚硬，地基不均匀沉降是其主要原因。
