Q71. You administer an instance of SQL Server 2014.
You are tasked with tuning a common set of queries. You have the results of several test executions, along with query plans. The schema and the data for all database object(s) used remain unchanged between executions. The QueryTime column is defined as a computed column that uses the GETDATE() system function. The query plans and results are shown below: You need to make an initial diagnosis of the situation, based solely on this input
Which two statements can you make about the performance characteristics of this query? Each correct answer presents a complete solution. Choose two.
A. The queries would perform better if the index named AccountNumber included the Name and QueryTime column.
B. The queries would perform worse if the index named AccountNumber included the NameColumn.
C. The queries would perform better if the index named AccountNumber included the Name column.
D. The object Account is a table, with an index having a leading column of AccountNumber and a Clustered Index named PKAccount.
E. The object Account is an indexed view, with an index having a leading column of AccountNumber and a Clustered Index named PKAccount.
F. The object Account is a view, joining the Account-AccountNumber and Account.PKAccount objects together.
Q72. Topic 8)
You have a table named Table1. Table1 has 1 million rows.

to import the data.
What should you do?
To answer, move the appropriate actions from the list of actions to the answer area and
arrange them in the correct order.
Q73. You are creating a table named Orders.
You need to ensure that every time a new row is added to the Orders table, a user-defined function is called to validate the row before the row is added to the table.
What should you use?
More than one answer choice may achieve the goal. Select the BEST answer.
A. A data manipulation language (DML) trigger
B. A DEFAULT constraint
C. A Data Definition Language (DDL) trigger
D. A CHECK constraint

Q74. You are testing disaster recovery procedures.
When you attempt to restore ProductsDB to another server, you receive the following error message: "Msg 33111, Level 16, State 3, Line 5 Cannot find server certificate with thumbprint '
Msg 3013, Level 16, State 1, Line 5
RESTORE DATABASE is terminating abnormally."
You need to ensure that you can restore ProductsDB to another server.

A. Option A
B. Option B
C. Option C
D. Option D
Q75. You create a table named Customers by using the following code segment:
You create a non-clustered index named IX_Name on the name column.
You write the following query to retrieve all of the customers that have a name that starts with the letters SMI:
You discover that the query performs a table scan. You need to ensure that the query uses the index. What should you do?
A. Replace LEFT(name,3) = 'smi' by using name like 'smi%'
B. Replace LEFT(name,3) = 'smi' by using substring(name,l,3) = 'smi'
C. Recreate IX_Name as a unique index
D. Recreate IX Name as a clustered index
Q76. You have database objects that were created by using the following script:
The dbo.Customers table has 1 million rows.
You discover that usp_GetCustomersByDate takes a long time to complete.
The query plan used by the stored procedure is shown in the exhibit. (Click the Exhibit
You need to ensure that usp_GetCustomersByDate completes as quickly as possible. What should you do?

You need to reduce the size of the log file. The solution must ensure that you can perform
transaction log backups in the future. Which code segment should you execute? To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.
