QUESTION 2
You need to redesign the system to meet the scalability requirements of the application.
Develop the solution by selecting and arranging the required code blocks in the correct order. You may not need all of
the code blocks.
Select and Place:
Correct Answer:
Note:
*
MEMORY_OPTIMIZED_DATA
First create a memory-optimized data filegroup and add a container to the filegroup.
Then create a memory-optimized table.
*
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.
*
Example:
— create a durable (data will be persisted) memory-optimized table — two of the columns are indexed
CREATE TABLE dbo.ShoppingCart (
ShoppingCartId INT IDENTITY(1,1) PRIMARY KEY NONCLUSTERED, UserId INT NOT NULL INDEX ix_UserId
NONCLUSTERED HASH WITH
(BUCKET_COUNT=1000000),
CreatedDate DATETIME2 NOT NULL,
TotalPrice MONEY
) WITH (MEMORY_OPTIMIZED=ON)
GO
QUESTION 3
Your network contains a SQL Server 2012 instance named SQL1. SQL1 contains a database named DB1. DB1
contains three tables. The tables are configured as shown in the following table.
You plan to create indexes for the tables.
You need to identify which type of index must be created for each table. The solution must minimize the amount of time
required to return information from the tables.
Which type of index should you create for each table? To answer, drag the appropriate index type to the correct table in
the answer area.

Correct Answer:
QUESTION 4

You discover that the Customers table was created in the dbo schema.
You need to create a code segment to move the table to another schema named Schema2.
What should you create?
To answer, drag the appropriate code segments to the correct location in the answer area. (Answer choices may be

required code blocks in the correct order.
You may not need all of the code blocks.
Select and Place:
Correct Answer:
Note:
*
From scenario:
The mobile application will need to meet the following requirements:
· Update the location of the user by using a stored procedure named usp_AddMobileLocation.
*
DELAYED_DURABILITY
SQL Server transaction commits can be either fully durable, the SQL Server default, or delayed durable (also known as
lazy commit).
Fully durable transaction commits are synchronous and report a commit as successful and return control to the client
only after the log records for the transaction are written to disk. Delayed durable transaction commits are asynchronous
and report a commit as successful before the log records for the transaction are written to disk. Writing the transaction
log entries to disk is required for a transaction to be durable. Delayed durable transactions become durable when the
transaction log entries are flushed to disk.
QUESTION 6

You need to ensure that you can insert rows into the underlying tables by using the view.
What should you do?
A. Create an INSTEAD OF trigger on the view.
B. Define the view by using the SCHEMABINDING option.
C. Define the view by using the CHECK option.
D. Materialize the view.
Correct Answer: C

“Msg 916, Level 14, State 1, Line 1

QUESTION 11
DRAG DROP
You have a database named database1. Each table in database1 has one index per column.
Users often report that creating items takes a long time.
You need to perform the following maintenance tasks:
Identify unused indexes.
Identify which indexes should be created.
What should you use?
To answer, drag the appropriate function to the correct management task in the answer area. (Answer choices may be
used once, more than once, or not at all.)
Select and Place:
Correct Answer:
Box 1: sys.dm_db_index_usage_stats
sys.dm_db_index_usage_stats shows you how many times the index was used for user queries. It returns counts of
different types of index operations and the time each type of operation was last performed in SQL Server.
Box 2: sys.dm_db_missing_index_details
sys.dm_db_missing_index_details returns detailed information about a missing index; for example, it returns the name
and identifier of the table where the index is missing, and the columns and column types that should make up the
missing
index.

QUESTION 12
DRAG DROP
You use the following statement to create a table.
You have the following queries.
You need to create an index to minimize the execution time of the queries.
How should you complete the statement? To answer, drag the appropriate code elements to the correct locations. Each
code element may be used once, more than once, or not at all. You may need to drag the split bar between panes or
scroll to view content.
Select and Place:
Correct Answer:
Box 1: LastName Redesign nonclustered indexes with a large index key size so that only columns used for searching
and lookups are key columns. Make all other columns that cover the query into nonkey columns. In this way, you will
have all columns needed to cover the query, but the index key itself is small and efficient.
Box 2: FirstName
Box 3: DepartmentID Non-key columns, called included columns, can be added to the leaf level of a nonclustered index
to improve query performance by covering the query. That is, all columns referenced in the query are included in the
index as either key or non-key columns. This allows the query optimizer to locate all the required information from an
index scan; the table or clustered index data is not accessed.
Box 4: OfficeID
QUESTION 13
You need to add a new column named Confirmed to the Employees table. The Confirmed column has the following
requirements:
1.
It must have a default value of TRUE.
2.
It must minimize the amount of disk space used. Which Transact-SQL statement should you run?
A. ALTER TABLE Employees ADD Confirmed but DEFAULT 0;
B. ALTER TABLE Employees ADD Confirmed but DEFAULT 1;
C. ALTER TABLE Employees ADD Confirmed nchar(1) DEFAULT \\’1\\’;
D. ALTER TABLE Employees ADD Confirmed nchar(1) DEFAULT \\’0\\’;
