Q51. You review a query that runs slowly. The query accesses data in a table named Schema1.Table1.
The following is the relevant portion of the execution plan for the query: You need to create the missing index.
Which code segment should you execute?
A. CREATE NONCLUSTERED INDEX IX1 on Schema1.Table1 (Column1) INCLUDE (Column4) WHERE Column2 <> Column3
B. CREATE NONCLUSTERED INDEX IX1 on Schema1.Table1 (Column1)
C. CREATE NONCLUSTERED INDEX IX1 on Schema1.Table1 (Column1, Column2, Column3) INCLUDE (Column4)
D. CREATE NONCLUSTERED INDEX IX1 on schema1.Table1 (Column1) INCLUDE (Column4)
Answer: C
Q52. Topic 8)
You are designing two stored procedures named Procedure1 and Procedure2.
You identify the following requirements:
. Procedure1 must take a parameter that ensures that multiple rows of data can pass into the stored procedure. . Procedure2 must use business logic that resides in a Microsoft .NET Framework assembly.
You need to identify the appropriate technology for each stored procedure.
Which technologies should you identify?
To answer, drag the appropriate technology to the correct stored procedure in the answer area. (Answer choices may be used once, more than once, or not at all.)
Answer:
Q53. Topic 8)
You are planning two stored procedures named SProc1 and SProc2. You identify the following requirements:
. SProc1 must return a table.
. SProc2 must return a status code.
You need to identify which options must be implemented to meet each stored procedure requirement.
Which options should you identify?
To answer, drag the appropriate option to the correct requirement in the answer area. (Answer choices may be used once, more than once, or not at all.)
Answer:
Q54. Topic 8)
You have a table named Table1 that contains 1 million rows. Table1 contains a column named Column1 that stores sensitive information. Column1 uses the nvarchar(16) data type.
You have a certificate named Cert1.
You need to replace Column1 with a new encrypted column that uses two-way encryption.
Which code segment should you execute before you remove Column1?
To answer, move the appropriate code segments from the list of code segments to the
answer area and arrange them in the correct order.
Answer:
Q55. Topic 8)
You create a disk-based table that contains the following script:
You need to prevent duplicate values in the SKU field.
Which five code segments should you use?
To answer, move the appropriate code segments from the list of code segments to the
answer area and arrange them in the correct order.
Answer:
Q56. Topic 8)
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 indexes that need to be defragmented. 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.)
Answer:
Q57. Topic 8)
You have a SQL Server 2012 database named Database1. Database1 has a data file named Database1_data.mdf and a transaction log named Database1jog.ldf. Database1_data.mdf is 1.5 GB. Database1jog.ldf is 1.5 terabytes.
A full backup of Database1 is performed every day.
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.
Answer:
Q58. Topic 7)
You need to create the usp.AssignUser stored procedure.
Develop the solution by selecting and arranging the required code blocks in the correct order. You may not need all of the code blocks.
Answer:
Q59. Topic 8)
You administer a SQL Server 2014 instance.
The server is capable of 10000 IO/second (IOPS). During the time period when the second process executes, the disk IO can reach 7000 IOPS, and CPU use can average 30% over the eight processors.
The first process summarizes the day's activity executed by a login of [SummaryReportLogin]. The second process submits transactions executed by a login of [ETLLogin].
A Resource Governor classifier function has been created to return WG_Low for connections from the [ETLLogin] and [SummaryReportLogin].
You need to set up the Resource Group and Workgroup Pools on the instance.
You have the following requirements:
. Both processes must never use more than 50 percent of the CPU at any one time. . The number of active queries that these processes can execute simultaneously should be limited to a maximum of 10. . The SummaryReportLogin process must always achieve the minimum IOPS required to be minimally affected during executing the ETLLogin processes.
Develop the solution by selecting and arranging the required code blocks in the correct order.
You may not need all of the code blocks.
Answer:
149. You are creating a table named Orders.
You need to ensure that every time a new row is added to the Orders table, a table that is
used for auditing is updated.
What should you use?
More than one answer choice may achieve the goal. Select the BEST answer.
A. A Data Definition Language (DDL) trigger
B. A DEFAULT constraint
C. A CHECK constraint
D. A FOREIGN KEY constraint
E. A data manipulation language (DML) trigger
Answer: E
