You are creating a console application by using C#.
You need to access the application assembly.
Which code segment should you use?
A. Assembly.GetAssembly(this);
B. this.GetType();
C. Assembly.Load();
D. Assembly.GetExecutingAssembly();
Answer: D
Explanation:
Assembly.GetExecutingAssembly - Gets the assembly that contains the code that is currently executing. http://msdn.microsoft.com/en-us/library/system.reflection.assembly.getexecutingassembly(v=vs.110).aspx
Assembly.GetAssembly - Gets the currently loaded assembly in which the specified class is defined. http://msdn.microsoft.com/en-us/library/system.reflection.assembly.getassembly.aspx

You are implementing a method named ProcessFile that retrieves data files from web servers and FTP servers. The ProcessFile () method has the following method signature:
Public void ProcessFile(Guid dataFileld, string dataFileUri)
Each time the ProcessFile() method is called, it must retrieve a unique data file and then save the data file to disk.
You need to complete the implementation of the ProcessFile() method. Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Explanation: * WebRequest.Create Method (Uri)
Initializes a new WebRequest instance for the specified URI scheme.
* Example:
1. To request data from a host server
Create a WebRequest instance by calling Create with the URI of the resource.
C#
WebRequest request = WebRequest.Create("http://www.contoso.com/");
2. Set any property values that you need in the WebRequest. For example, to enable authentication, set the Credentials property to an instance of the NetworkCredential class.
C#
request.Credentials = CredentialCache.DefaultCredentials;
3. To send the request to the server, call GetResponse. The actual type of the returned WebResponse object is determined by the scheme of the requested URI.
C#
WebResponse response = request.GetResponse();
4. To get the stream containing response data sent by the server, use the GetResponseStream method of the WebResponse.
C#
Stream dataStream = response.GetResponseStream ();

Answer: C
Q5. - (Topic 2)
You are developing code for an application that retrieves information about Microsoft .NET Framework assemblies.
The following code segment is part of the application (line numbers are included for reference only):
You need to insert code at line 04. The code must load the assembly. Once the assembly is loaded, the code must be able to read the assembly metadata, but the code must be denied access from executing code from the assembly.
Which code segment should you insert at line 04?
A. Assembly.ReflectionOnlyLoadFrom(bytes);
B. Assembly.ReflectionOniyLoad(bytes);
C. Assembly.Load(bytes);
D. Assembly.LoadFrom(bytes);
Answer: C
Q6. - (Topic 1)
You are developing an application. The application includes classes named Employee and Person and an interface named IPerson.
The Employee class must meet the following requirements:
. It must either inherit from the Person class or implement the IPerson interface. . It must be inheritable by other classes in the application.
You need to ensure that the Employee 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: B,D
Explanation:
Sealed - 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
Q7. - (Topic 2)
You are creating an application that reads from a database.
You need to use different databases during the development phase and the testing phase by using conditional compilation techniques.
What should you do?
A. Configure the assembly metadata to use the pre-existing public key for the assembly identity by using the AssemblySignatureKeyAttribute attribute.
B. Disable the strong-name bypass feature of Microsoft .NET Framework in the registry.
C. Configure the Define DEBUG constant setting in Microsoft Visual Studio.
D. Decorate the code by using the [assembly:AssemblyDelaySignAttribute(true)] attribute.
Answer: C
Explanation: Use one debug version to connect to the development database, and a standard version to connect to the live database.
Q8. - (Topic 2)
You are developing an application that includes methods named EvaluateLoan, ProcessLoan, and FundLoan. The application defines build configurations named TRIAL, BASIC, and ADVANCED.
You have the following requirements:
The TRIAL build configuration must run only the EvaluateLoan() method.
The BASIC build configuration must run all three methods.
The ADVANCED build configuration must run only the EvaluateLoan() and
ProcessLoan() methods.
You need to meet the requirements.
Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Q9. DRAG DROP - (Topic 2)
You have the following code.
You need to return all of the products and their associated categories.
How should you complete the code? To answer, drag the appropriate code elements to the correct targets in the answer area. Each code element may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

Q10. - (Topic 2)
You are creating a class library that will be used in a web application. You need to ensure that the class library assembly is strongly named. What should you do?
A. Use assembly attributes.
B. Use the csc.exe /target:Library option when building the application.
C. Use the xsd.exe command-line tool.
D. Use the EdmGen.exe command-line tool.
Answer: A
Explanation: The Windows Software Development Kit (SDK) provides several ways to sign an assembly with a strong name:
* (A) Using assembly attributes to insert the strong name information in your code. You can use either the AssemblyKeyFileAttribute or the AssemblyKeyNameAttribute, depending on where the key file to be used is located.
* Using the Assembly Linker (Al.exe) provided by the Windows SDK.
* Using compiler options such /keyfile or /delaysign in C# and Visual Basic, or the /KEYFILE or /DELAYSIGN linker option in C++. (For information on delay signing, see Delay Signing an Assembly.)
Q11. - (Topic 2)
You are creating a class library that will be used in a web application.
You need to ensure that the class library assembly is strongly named.
What should you do?
A. Use the csc.exe /target:Library option when building the application.
B. Use the AL.exe command-line tool.
C. Use the aspnet_regiis.exe command-line tool.
D. Use the EdmGen.exe command-line tool.
Answer: B
Explanation: The Windows Software Development Kit (SDK) provides several ways to sign an assembly with a strong name:
* Using the Assembly Linker (Al.exe) provided by the Windows SDK.
* Using assembly attributes to insert the strong name information in your code. You can use either the AssemblyKeyFileAttribute or the AssemblyKeyNameAttribute, depending on where the key file to be used is located.
* Using compiler options such /keyfile or /delaysign in C# and Visual Basic, or the
/KEYFILE or /DELAYSIGN linker option in C++. (For information on delay signing, see
Delay Signing an Assembly.)
Note:
* A strong name consists of the assembly's identity—it’s simple text name, version number, and culture information (if provided)—plus a public key and a digital signature. It is generated from an assembly file (the file that contains the assembly manifest, which in turn contains the names and hashes of all the files that make up the assembly), using the corresponding private key. Microsoft. Visual Studio. .NET and other development tools provided in the .NET Framework SDK can assign strong names to an assembly.
Assemblies with the same strong name are expected to be identical.

You need to ensure that the implementation of the EmployeeType property meets the requirements.
Which two actions should you perform? (Each correct answer represents part of the complete solution. Choose two.)
A. Replace line 05 with the following code segment: protected get;
B. Replace line 06 with the following code segment: private set;
C. Replace line 03 with the following code segment: public string EmployeeType
D. Replace line 05 with the following code segment: private get;
