the correct locations in the answer area-Each attribute 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.)

Question #87 - Topic 1

You develop an application that displays information from log files when errors occur. The
application will prompt the user to create an error report that sends details about the error
and the session to the administrator.
When a user opens a log file by using the application, the application throws an exception
and closes.
The application must preserve the original stack trace information when an exception
occurs during this process.
You need to implement the method that reads the log files.
How should you complete the relevant code? (To answer, drag the appropriate code
segments to the correct locations in the answer area. Each code segment 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.)

Question #88 - Topic 1

You are creating a class named Employee. The class exposes a string property named
EmployeeType. The following code segment defines the Employee class. (Line numbers
are included for reference only.)

The EmployeeType property value must be accessed and modified only by code within the
Employee class or within a class derived from the Employee class.
You need to ensure that the implementation of the EmployeeType property meets the
requirements.
