Answer:

Topic 5, Litware, Inc 

Overview 

General Overview 

You are a database developer for a company named Litware, Inc. Litware has a main office in Miami. 

Litware has a job posting web application named WebApp1. WebApp1 uses a database named DB1. DB1 is hosted on a server named Server1. The database design of DB1 is shown in the exhibit. (Click the Exhibit button.) 

WebApp1 allows a user to log on as a job poster or a job seeker. Candidates can search for job openings based on keywords, apply to an opening, view their application, and load their resume in Microsoft Word format. Companies can add a job opening, view the list of candidates who applied to an opening, and mark an application as denied. 

Users and Roles 

DB1 has five database users named Company, CompanyWeb, Candidate, CandidateWeb, and Administrator. 

DB1 has three user-defined database roles. The roles are configured as shown in the following table. 

Keyword Search 

The keyword searches for the job openings are performed by using the following stored procedure named usp_GetOpenings: 

Opening Update 

Updates to the Openings table are performed by using the following stored procedure named usp_UpdateOpening: 

Problems and Reported Issues 

Concurrency Problems 

You discover that deadlocks frequently occur. 

You identify that a stored procedure named usp_AcceptCandidate and a stored procedure named usp_UpdateCandidate generate deadlocks. The following is the code for usp_AcceptCandidate: 

Salary Query Issues 

Users report that when they perform a search for job openings without specifying a minimum salary, only job openings that specify a minimum salary are displayed. 

Log File Growth Issues 

The current log file for DB1 grows constantly. The log file fails to shrink even when the daily SQL Server Agent Shrink Database task runs. 

Performance Issues 

You discover that a stored procedure named usp_ExportOpenings takes a long time to run and executes a table scan when it runs. 

You also discover that the usp_GetOpenings stored procedure takes a long time to run and that the non-clustered index on the Description column is not being used. 

Page Split Issues 

On DB1, many page splits per second spike every few minutes. 

Requirements 

Security and Application Requirements 

Litware identifies the following security and application requirements: . Only the Administrator, Company, and CompanyWeb database users must be able to execute the usp_UpdateOpening stored procedure. . Changes made to the database must not affect WebApp1. 

Locking Requirements 

Litware identifies the following locking requirements: . The usp_GetOpenings stored procedure must not be blocked by the usp_UpdateOpening stored procedure. . If a row is locked in the Openings table, usp_GetOpenings must retrieve the latest 

version of the row, even if the row was not committed yet. 

Integration Requirements 

Litware exports its job openings to an external company as XML data. The XML data uses the following format: 

A stored procedure named usp_ExportOpenings will be used to generate the XML data. The following is the code for usp_ExportOpenings: 

The stored procedure will be executed by a SQL Server Integration Services (SSIS) package named Package1. 

The XML data will be written to a secured folder named Folder1. Only a dedicated Active Directory account named Account1 is assigned the permissions to read from or write to Folder1. 

Refactoring Requirements 

Litware identifies the following refactoring requirements: . New code must be written by reusing the following query: 

. The results from the query must be able to be joined to other queries. 

Upload Requirements 

Litware requires users to upload their job experience in a Word file by using WebApp1. WebApp1 will send the Word file to DB1 as a stream of bytes. DB1 will then convert the Word file to text before the contents of the Word file is saved to the Candidates table. 

A database developer creates an assembly named Conversions that contains the following: 

. A class named Convert in the SqlConversions namespace 

. A method named ConvertToText in the Convert class that converts Word files to 

text 

The ConvertToText method accepts a stream of bytes and returns text. The method is used in the following stored procedure: 

Job Application Requirements 

A candidate can only apply to each job opening once. 

Data Recovery Requirements 

All changes to the database are performed by using stored procedures. WebApp1 generates a unique transaction ID for every stored procedure call that the application makes to the database. 

If a server fails, you must be able to restore data to a specified transaction. 


Q93. You have a text file that contains an XML Schema Definition (XSD). 

You have a table named Schema1.Table1. 

You have a stored procedure named Schema1.Proc1 that accepts an XML parameter 

named Param1. 

You need to store validated XML data in Schema1.Table1. The solution must ensure that only valid XML data is accepted by Param1. What should you do? (Each correct answer presents part of the solution. Choose all that 

apply.) 

A. Define an XML column in Table1 by using an XML schema collection. 

B. Create an XML schema collection in the database from the text file. 

C. Declare Param1 var1 as type XML and associate the variable to the XML schema collection. 

D. use the modify method to insert the XML schema into each row of the XML column in Table1. 

Answer: A,B,D 

Explanation: Explanation/Reference: http://msdn.microsoft.com/en-us/library/bb510420.aspx http://msdn.microsoft.com/en-us/library/ms187856.aspx http://msdn.microsoft.com/en-us/library/ms176009.aspx http://msdn.microsoft.com/en-us/library/hh403385.aspx http://msdn.microsoft.com/en-us/library/ms184277.aspx 


Q94. 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:

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. 


Q95. You plan to migrate an instance of SQL Server 2008 to a new installation of SQL Server 2012. 

You need to migrate alerts and e-mail notifications. 

Which system stored procedures should you use? (Each correct answer presents part of the solution. Choose all that apply.) 

A. sp_syspolicy_create_job 

B. sp_add_operator 

C. sp_audit_write 

D. sp_add_alert 

Answer: B,C 

Explanation: B: sp_add_operator 

Creates an operator (notification recipient) for use with alerts and jobs. 

C: sp_audit_write Adds a user-defined audit event to the USER_DEFINED_AUDIT_GROUP. If USER_DEFINED_AUDIT_GROUP is not enabled, sp_audit_write is ignored. 


Q96. 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:


Q97. You have a SQL Server 2012 instance that hosts a single-user database. 

The database does not contain user-created stored procedures or user-created functions. 

You need to minimize the amount of memory used for query plan caching.

A. Scan for Startup Procs 

B. Enable Contained Databases 

C. Optimize for Ad hoc Workloads 

D. Allow Triggers to Fire Others 

Answer:

You need to reduce the amount of time it takes to execute Proc1. 

What should you do? 

A. Option A 

B. Option B 

C. Option C 

D. Option D 

Answer:

Which statement should you use? 

A. CREATE SCHEMA SessionDataTable 

B. CREATE TYPE SessionDataTable AS Table 

C. CREATE TABLE SessionDataTable 

D. CREATE XML SCHEMA COLLECTION SessionDataTable 

Answer:


Q100. You execute the following code. After populating the Employees table with 10,000 rows, you execute the following query: 

You need to reduce the amount of time it takes to execute the query. 

What should you do? 

A. Partition the table and use the JobTitle column for the partition scheme. 

B. Change SUBSTRING(JobTitle,l,l) = 'C to JobTitle LIKE 'c%’ 

C. Change SUBSTRING (JobTitle, 1,1] = 'c' to LEFT(JobTitle ,1) = 'c'. 

D. Replace IX_Employees with a clustered index.
