What is core-based licensing and which SQL Server 2012 edition requires it?
What will be an ideal response?
Core-based licensing measures the computing power of the host server by counting the number of processing cores. It replaces processor-based licensing in earlier versions of SQL Server. A core is a physical unit within a processor that reads and executes program instructions. Traditionally, a processor was based on a single core, although multicore processors are now commonplace. A multicore processor is a processor with more than one core processing unit; it is able to execute multiple instruction sets in parallel with a consequent improvement in performance. Given the widespread adoption of multicore processors, Microsoft considers the number of cores to be a more relevant metric to measure processing power for SQL Server 2012. The core-based licensing model is the only model available for the Enterprise Edition, and it might make sense for the Standard Edition when it is impractical to count the number of users. A license is based on a four-core minimum with one-core increments.

Which of the following statements about row heights and column widths in a Grid is false?
a) Each row’s height and each column’s width can be specified as an explicit size, a relative size (using *) or Auto. b) Auto makes the contents as big as it needs to be to fit its row or column. c) The setting * specifies the size of a row or column with respect to the Grid’s other rows and columns. For example, a column with a Height of 2* would be twice the size of a column that is 1* (or just *). d) A Grid first allocates its space to the rows and columns that explicitly define their sizes or that are configured to allow the layout to automatically determine their sizes. The remaining space is divided among the other rows and columns.
