You are developing an assembly.
You plan to sign the assembly when the assembly is developed.
You need to reserve space in the assembly for the signature.
What should you do?

You have the following code (line numbers are included for reference only):

You need to ensure that if an exception occurs, the exception will be logged.
Which code should you insert at line 28?

You are troubleshooting an application that uses a class named FullName. The class is decorated
with the DataContractAttribute attribute. The application includes the following code. (Line numbers
are included for reference only.)

You need to ensure that the entire FullName object is serialized to the memory stream object.
Which code segment should you insert at line 09?

You write the following method (line numbers are included for reference only):

You need to ensure that the method extracts a list of URLs that match the following pattern:
@http://(www\\.)?([^\\.]+)\\.com;
Which code should you insert at line 07?

You have the following code:

You need to retrieve all of the numbers from the items variable that are greater than 80.
Which code should you use?

You are developing an application that uses several objects. The application includes the following
code segment. (Line numbers are included for reference only.)

You need to evaluate whether an object is null.
Which code segment should you insert at line 03?

You are implementing a new method named ProcessDat
a The ProcessData() method calls a third-party component that performs a long-running operation
to retrieve stock information from a web service.
The third-party component uses the IAsyncResult pattern to signal completion of the long-running
operation so that the UI can be updated with the new values.
You need to ensure that the calling code handles the long-running operation as a
System.Threading.Tasks.Task object to avoid blocking the UI thread.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)

You are developing a class named Account that will be used by several applications.
The applications that will consume the Account class will make asynchronous calls to the Account
class to execute several different methods.
You need to ensure that only one call to the methods is executed at a time.
Which keyword should you use?

You are developing an application by using C#. The application will write events to an event log. You
plan to deploy the application to a server.
You create an event source named MySource and a custom log named MyLog on the server.
You need to write events to the custom log.
Which code segment should you use?

You plan to store passwords in a Windows Azure SQL Database database.
You need to ensure that the passwords are stored in the database by using a hash algorithm,
Which cryptographic algorithm should you use?
