C) Write error messages to the event logs on the local computers. Use Windows Management Instrumentation (WMI) to view the error information.
D) Write error messages to the SQL Server databases. Synchronize the databases by using transactional replication.

2. You are designing a Windows application by using Microsoft .NET Framework 4.
Remote users have limited network connectivity. Users will not have write permissions to
the local file system.

What are two possible message exchange patterns that will meet the requirements? (Each correct answer presents a complete solution. Choose two.)

A) Datagram with session
B) Datagram without session
C) Duplex
D) Request-Response

4. You are designing a Windows Presentation Foundation (WPF) application that connects to a data access layer on a server.
You have the following requirements for all security-related exceptions:

From which class should you inherit?

A) System.ApplicationException
B) System.InvalidOperationException
C) System.AccessViolattonException

5. You are modifying an existing Windows Presentation Foundation (WPF) application that uses .NET Framework 4. The WPF application uses a wizard to capture data and insert the data into a database. The database includes one parent table and many child tables.
Inserting captured data in the database locks many database tables and delays application access.
You have the following requirements:
Reduce delays when saving datA.
Ensure that other application users are not blocked from reading datA.
Ensure that captured data is available only after all child tables are updated.
You need to recommend an approach for inserting captured data into the database.
---
What should you recommend?
