- 1. You develop an inventory management application called XYZManagement that will call a Microsoft SQL Server stored procedure named sp_GetDailyXYZSales. The stored procedure will run a query that returns your daily sales total as an output parameter. This total will be displayed to users in a message box. Your application uses a SqlCommand object to run sp_GetDailyXYZSales. You write the following code to call sp_GetDailyXYZSales: SqlConnection cnn = new SqlConnection(myConnString); SqlCommand cmd = new SqlCommand(?sp_GetDaily XYZ Sales?, cnn); cmd.CommandType = CommandType.StoredProcedure; SqlParameter prm = cmd.Parameters.Add(?@ItemTotal?,SqlDbType.Int); prm.Direction = ParameterDirection.Output; cnn.Open(); cmd.ExecuteNonQuery(); Now you must write additional code to access the output parameter. Which code segment should you use?
Options- A. MessageBox.Show(?Total is: ? + cmd.Parameters[?@Output?].Value.ToString());
- B. MessageBox.Show(?Total is: ? + cmd.Parameters[?@Output?].ToString());
- C. MessageBox.Show(?Total is: ? + cmd.Parameters[?@ItemTotal?
- D. MessageBox.Show(?Total is: ? + cmd.Parameters[?@ItemTotal? Discuss
- 2. You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database. You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction. The code for the middle-tier component will implement the following objects: SqlConnection cn = new SqlConnection(); SqlTransaction tr; If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies. Which code segment should you use?
Options- A. tr = cn.BeginTransaction(?ReadCommitted?);
- B. tr = cn.BeginTransaction(IsolationLevel.ReadCommitted);
- C. tr = cn.BeginTransaction(IsolationLevel.Serializable);
- D. tr = cn.BeginTransaction(?Serializable?); Discuss

Correct Answer: MessageBox.Show(?Total is: ? + cmd.Parameters[?@ItemTotal?
Explanation:
The @ItemTotal parameter is declared as an output parameter with SQL Server data type INT.We use the Value property of the SQLParameter class to retrieve the value of this parameter. We must also convert the INT value to a string value with the ToString method. We then supply this string to the MessageBox.Show method.
Incorrect Answers
Option A, B:
The @ItemTotal parameter is the output parameter. Using @Output this way is incorrect. Output is a keyword and no variable named @Output has been declared.
Option D:
We must use the Value method to retrieve the value of the parameter..
Correct Answer: tr = cn.BeginTransaction(IsolationLevel.Serializable);
Explanation:
Serializable is the highest isolation transaction level. It provide the highest possible level of protection against concurrent data errors. The correct syntax to begin a transaction with this transaction isolation level is: cn.BeginTransaction(IsolationLevel.Serializable)
Correct Answer: Generate a registry file for the assembly by using the Assembly Registration tool (Regasm.exe) Register the file on the client computer.
Explanation:
The Assembly Registration tool reads the metadata within an assembly and adds the necessary entries to the registry, which allows COM clients to create .NET Framework classes transparently. Once a class is registered, any COM client can use it as though the class were a COM class..
Incorrect Answers:
Option A:
The Strong Name tool helps sign assemblies with strong names.
Option B:
The Type Library Importer, tlbimp.exe, converts the type definitions found within a COM type library into equivalent definitions in a common language runtime assembly. It would not be useful in this scenario however.
Option D:
This would not allow the COM application to use the class.
Correct Answer: Implement declarative security and execute the minimum permission request to allow access to the file system and Windows registry.
Explanation:
You can use declarative code access security to request permissions for the entire assembly. SecurityAction flags that can be specified in an assembly-wide directive. When SecurityAction.RequestMinimum is specified, it makes a request to the common language runtime to be granted the requested permission. If the requested permission is not granted by the security policy, the assembly will not execute. A Security Action.RequestOptional is similar, but the assembly will still run even if the requested permission is not granted. Specifying security Action. RequestRefuse requests that the assembly be denied the specified permission.
You must use the Assembly (assembly) directive when specifying these actions as follows:
Option A:
There are only three Security actionAttributes targets for an assembly: RequestMinimumAssembly, RequestOptionalAssembly, and RequestRefuseAssembly.
Option C, D:
Imperative security does not work well to configure security for an entire assembly. In imperative security, permission to execute is demanded at run time.
Correct Answer: In the PrintPage event, set the HasMorePages property of the PrintPageEventArgs object to True.
Explanation:
PrintDocument.PrintPage Event occurs when the output to print for the current page is needed. This event has the HasMorePages property which gets or sets a value indicating whether an additional page should be printed.
Correct Answer: Rs.500
Explanation:
CP. of each share= Rs.(25 + 2% of 25) = Rs.25.50.
Number of shares= = 500
Correct Answer: Remove the TABLOCK option from the BULK INSERT statement.
Explanation:
The TABLOCK hint increases the number of locks during the adding process. This is the reason why response time are slows down during this process. By removing the TABLOCK hint the default more granular row-level lock will be used. This would decrease the scope of the locks which would result in less waiting jobs and performance would improve.
Note: The BULK INSERT statement is used to copy a data file into a database table or view in a format specified by the user. The BULK INSERT statement accepts the TABLOCK hint, which allows the user to specify the locking behavior that the BULK INSERT statement should use. TABLOCK specifies that a bulk update table-level lock is taken for the duration of the bulk copy. If TABLOCK is not specified, the default uses row-level locks.
Correct Answer: EXEC sp_defaultdb 'Andrew','FinanceData'
Explanation:
Error 208 produces the message 'Invalid object name' and occurs when an object that does not exist in the current database is referenced. If the object exists in another database, we must use the USE statement to explicitly switch the context to the correct database or we must qualify the object name with the database name. A third option is to use the sp_defaultdb stored procedure. This stored procedure is used to change the default database for a login. When a client connects with SQL Server, the default database defined for its login becomes the current database without an explicit USE statement. The default database can be defined when the login is added with
sp_addlogin. When executing sp_addlogin the master database is the default database if a database is not specified. In this scenario a SQL Server 2000 login and a user account has been created for Andrew and he has been given database access and the required permissions.
Correct Answer: Configure SQL Server to use only processors 1, 2, and 3.
Explanation:
The system monitor clearly indicates that the processors are overloaded. We need to decide which processors we should use for SQL Server. Processor 0 is the default CPU for the I/O subsystem. Network Interface Cards (NIC) are assigned to the remaining CPUs, starting from the highest-numbered CPU. The NIC would get processor 3.
SQL Server would be using all four processors by default.
The Windows NT/2000/XP operating system use processor 0. In order to avoid the logon
problems we should not let SQL Server to use this processor. Instead SQL Server should be configured to use processor 1, 2, and 3.
Note 1: The Affinity mask is used to exclude a processor on a multiprocessor computer from processing SQL Server 2000 threads. Default is equal distribution of SQL Server 2000 processes across all processors.
Note 2: Monitoring the Processor and System object counters provides information about the CPU utilization and helps in determining whether or not a bottleneck exists. The %Total Processor Time is used on multiple CPU Severs to gauge the average activity of the processors and shows the percentage of elapsed time that a processor is busy executing a nonidle thread. Values around 100 percent on a Server computer that processes many client requests indicate that processes are queuing up, waiting for processor time, and causing a bottleneck. Such a sustained high level of processor usage is unacceptable for a server.
Correct Answer: Increase the time between the differential backup and the DBCC SHRINKDATABASE job.
Explanation:
The DBCC SHRINKDATABSE cannot be executed until the previous job step, the differential backup, has been completed. We should increase the time between these two job steps, or even better configure the last job step to run only after the differential backup has been completed.
Note: The DBCC SHRINKDATABASE statement shrinks data files on a per-file basis but shrinks log files as if all the log files existed in one contiguous log pool. The target size for the data and log files cannot be smaller than the minimum size of a file that was specified when the file was originally created, or the last explicit size set with a file size changing operation such as the ALTER DATABASE statement with the MODIFY FILE option or the DBCC SHRINKFILE statement.
