1. You are designing the storage scheme for a new SQL Server 2008 database application. The application will primarily be
used to query data. The database will be initially populated with 4 terabytes of data stored in 20 tables. The data is distributed
evenly throughout all 20 tables.
Every night, between 100 GB and 300 GB of new data will be loaded into 4 database tables. The remaining 16 tables will
remain static. The average CPU utilization of the server where the application will reside is between 30 and 50 percent.
You need to ensure that the amount of disk space used is reduced. You need to achieve this goal by ensuring minimum impact
of performance on the server.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Use page-level data compression on the 4 tables that are loaded every night.
B. Use row-level data compression on the 4 tables that are loaded every night.
C. Use page-level data compression on the 16 tables that remain static.
D. Use row-level data compression on the 16 tables that remain static.
Answer: A
2. You are the database administrator for a SQL Server that hosts an application defined as follows:
?The database consists of 4 data files and one log file.
?The physical server has 16 CPUs and 64 GB of memory.
?Hardware non-uniform memory access (NUMA) is not available on this server platform.
Users of the application report that it is responding slowly. You use SQL Server Profiler to find out that the I/O performance
issue is related to the lazywriter process.
