Q92. - (Topic 2)
You are evaluating a method that calculates loan interest. The application includes the following code segment. (Line numbers are included for reference only.)
When the loanTerm value is 5 and the loanAmount value is 4500, the loanRate must be set to 6.5 percent.
You need to adjust the loanRate value to meet the requirements.
What should you do?
A. Replace line 15 with the following code segment: loanRate = 0.065m;
B. Replace line 07 with the following code segment: loanRate = 0.065m;
C. Replace line 17 with the following code segment: interestAmount = loanAmount * 0.065m * loanTerm;
D. Replace line 04 with the following code segment: decimal loanRate = 0.065m;
Answer: A
Q93. - (Topic 1)
You are developing an application. The application includes a method named ReadFile that reads data from a file. The ReadFile() method must meet the following requirements: . It must not make changes to the data file.
. It must allow other processes to access the data file. . It must not throw an exception if the application attempts to open a data file that does not exist.
You need to implement the ReadFile() method.
Which code segment should you use?
A. var fs = File.Open(Filename, FileMode.OpenOrCreate, FileAccess.Read, FileShare.ReadWrite);
B. var fs = File.Open(Filename, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
C. var fs = File.Open(Filename, FileMode.OpenOrCreate, FileAccess.Read, FileShare.Write);
D. var fs = File.ReadAllLines(Filename);
E. var fs = File.ReadAllBytes(Filename);
Answer: A
Explanation:
FileMode.OpenOrCreate - Specifies that the operating system should open a file if it exists; otherwise, a new file should be created. If the file is opened with FileAccess.Read, FileIOPermissionAccess.Read permission is required. If the file access is FileAccess.Write, FileIOPermissionAccess.Write permission is required. If the file is opened with FileAccess.ReadWrite, both FileIOPermissionAccess.Read and FileIOPermissionAccess.Write permissions are required.
http://msdn.microsoft.com/en-us/library/system.io.filemode.aspx
FileShare.ReadWrite - Allows subsequent opening of the file for reading or writing.If this flag is not specified, any request to open the file for reading or writing (by this process or another process) will fail until the file is closed.However, even if this flag is specified, additional permissions might still be needed to access the file. http://msdn.microsoft.com/pl-pl/library/system.io.fileshare.aspx
Q94. - (Topic 2)
You are debugging a 64-bit C# application.
Users report System.OutOfMemoryException exceptions. The system is attempting to use arrays larger than 2 GB in size.
You need to ensure that the application can use arrays larger than 2 GB.
What should you do?
A. Add the /3GB switch to the boot.ini file for the operating system.
B. Set the IMAGE_FILE_LARGE_ADDRESS_AWARE flag in the image header for the application executable file.
C. Set the value of the gcAllowVeryLargeObjects property to true in the application configuration file.
D. Set the value of the user-mode virtual address space setting for the operating system to MAX.
Answer: C
Q95. - (Topic 1)
You are developing an application. The application includes classes named Mammal and Animal and an interface named IAnimal.
The Mammal class must meet the following requirements: . It must either inherit from the Animal class or implement the IAnimal interface. . It must be inheritable by other classes in the application. You need to ensure that the Mammal class meets the requirements.
Which two code segments can you use to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A,C
Explanation:
When applied to a class, the sealed modifier prevents other classes from inheriting from it. http://msdn.microsoft.com/en-us/library/88c54tsw(v=vs.110).aspx
Q96. DRAG DROP - (Topic 1)
You have the following class:
You need to implement IEquatable. The Equals method must return true if both ID and Name are set to the identical values. Otherwise, the method must return false. Equals must not throw an exception.
What should you do? (Develop the solution by selecting and ordering the required code snippets. You may not need all of the code snippets.)
