QUESTION 1
You are writing the technical specification for your solution. Your new timesheet
application must be able to access timesheet entry data. You need to specify the
technology that will be used for accessing this data. Your solution must require the
minimum development effort. Which technology should you use?
A. a SQLConnection class
B. a .NET Remoting object that uses TCP channel and binary formatting
C. an XML Web service proxy class
D. an interop assembly
Answer: C
This is the best solution since data can also be accessed through the firewall.
Lawyer, Corporate Law Division: When we work at home, we want to be able to use the
application over the internet. When we do so, the application should update the data
immediately. To update the data immediately, a data layer webservice will have to be
called from the Windows Form Application. This can be accomplished by using an XML
Web service proxy class to make the call.
Note:
.NET Remoting vs. XML Web Services
XML Web services offer a simpler model for distributed applications than that provided
by .NET Remoting. XML Web services are fine-tuned for Internet scenarios and
cross-platform use. Although you can apply .NET Remoting in these scenarios, thanks to
its SOAP formatter and HTTP channel, .NET Remoting is more suitable as a high-speed
solution for binary communication between proprietary .NET components, usually over
an internal network. And although XML Web services can’t match the communication
speed of .NET Remoting over a binary channel, they still lend themselves to
high-performance designs thanks to their stateless nature and ASP.NET’s multithreaded
hosting service.
Here’s a quick overview of the major differences between the XML Web service and
.NET Remoting technologies:
1. The IT staff will not open additional ports: Because XML Web services work through
Microsoft Internet Information Services (IIS) and ASP.NET, they can communicate with
clients using the default HTTP channel (usually port 80). This means that consumers can
use XML Web services just as easily as they can download HTML pages from the
Internet. There’s no need for an administrator to open additional ports on a firewall.
2. Minimum development effort: Because of the restricted nature of XML Web services,
the design issues are simplified. XML Web services are generally easier to create than
remotable components (and easier to design well).
3. XML Web services are more restricted than objects exposed over .NET Remoting. An

XML Web service works in a similar way to a SingleCall .NET Remoting object. It isn’t
possible to create a singleton or a client-activated object.
4. Communication with .NET Remoting can be faster than XML Web service
communication if you use a binary formatter. XML Web services support only SOAP
message formatting, which uses larger XML text messages.
5. XML Web services support open standards that target cross-platform use. For
example, each .NET XML Web service has an associated WSDL document that describes
how a client can interact with the service. Therefore, any client that can parse an XML
message and connect over an HTTP channel can use an XML Web service, even if the
client is written in Java and hosted on a UNIX computer.
6.
XML Web services are designed for use between companies and organizations. They can
use a dynamic discovery mechanism or a UDDI registry that “advertises” services to
interested parties over the Internet.
7. XML Web services don’t require a dedicated hosting program because they are always
hosted by ASP.NET. That also means that they gain access to some impressive platform
services, including data caching, Web farm-ready session state management,
authentication, and an application collection for global, shareable objects. These features,
if required, can be extremely difficult to re-create by hand in a component exposed
through .NET Remoting.

Incorrect
Answer:
A. SQLConnection is a class that is part of ADO.Net technology. The class on its own is
not enough for data access. We must view solutions from a holistic view point.
B. Remoting requires more development effort than Web Services
D. This makes no sense. An interop assemble is a way to access data.
QUESTION 2
You are writing a conceptual diagram of the modules that must be developed for
your solution. Which module or modules should be included?(Choose all that apply)
A. a Web application for Team Leads and Business Planners
B. a timesheet entry database
C. a billing database
D. a notification engine that sends timesheet entry reminders
E. a timesheet entry application
F. a Windows CE application
G. a utility that uploads information to the billing application
Answer: A,B,E,F,G
We identify all modules.

D. This is not a requirement.
C: This is not required.
QUESTION 3
You are writing the technical specification for your solution. You need to select a
technology for the new timesheet application. Which technology should you use?
A. an XML Web service
B. a Web application
C. a console application
D. a Windows Forms application
Answer: B
There are three applications to be developed:
1. A web application for Team Leads and Business Planners. The Business Manager
wants “the new solution to be a Web application that is accessible from the
Internet.”
2. A simple time sheet Windows CE application for Lawyers in the Criminal Law
Division.
3. A web application for Lawyers in the Corporate Law Division. This refers to this
question.
It must be a web application because:
1. Critical constraint: Only TCP ports 80 and 443 are open. A Windows Form,
which uses an XML web service will be able to penetrate the firewall
2. Our web application does not require any client installation.
3. Data will be updated immediately when users work at home
4. The underlying XML Webservice which the windows Form will use is accessible
from the Internet, as required by the Business Manager
5. It is stated: “We envision a taskbar-type interface that should always be
displayed along the edge of the screen. This taskbar should contain toolbar-type
buttons.” A web application is capable of this.
Incorrect
Answer:
A: An XML Web Service does not have the type of user interface required to build
the application.
C,D: These alternatives will not meet the requirements.
