QUESTION 281
You use SQL Server 2014. The physical server is a dedicated database server that has 120GB of RAM available. There is approximately 50GB of storage space available on a slow local disk.
You create a new stored procedure.
You decide you need to temporarily hold approximately 300,000 rows from two tables, from which you will compute two complex business scores.
The stored procedure will use temporary storage defined as follows:
 
The code will make several passes through the data, applying complex calculations before writing the data to a permanent disk-based table in the same database from which it reads the data.
For this stored procedure, you need to deal with temporary data in the most efficient way to minimize physical disk pressure.
What should you do? More than one answer choice may achieve the goal. Select the BEST answer.
 

A.    Option A
B.    Option B
C.    Option C
D.    Option D

Answer: A
Explanation:
* You must specify a value for the BUCKET_COUNT parameter when you create the memory-optimized table. In most cases the bucket count should be between 1 and 2 times the number of distinct values in the index key. If the index key contains a lot of duplicate values, on average there are more than 10 rows for each index key value, use a nonclustered index instead
You may not always be able to predict how many values a particular index key may have or will have. Performance should be acceptable if the BUCKET_COUNT value is within 5 times of the actual number of key values.

QUESTION 282
You develop a Microsoft SQL Server 2012 database.
The database is used by two web applications that access a table named Products.
You want to create an object that will prevent the applications from accessing the table directly while still providing access to the required data.
You need to ensure that the following requirements are met:
Future modifications to the table definition will not affect the applications’ ability to access data.
The new object can accommodate data retrieval and data modification.
You need to achieve this goal by using the minimum amount of changes to the applications.
What should you create for each application?

A.    Synonyms
B.    Common table expressions
C.    Views
D.    Temporary tables

Answer: C
