QUESTION 1
You develop a Windows-based application named CertK WinApp that contains a Windows From
named Form1. To CertK WinApp, you add a Web reference to an XML Web service named Service1.
Service1 exposes two Web methods named Authenticate and RetrieveData. Both methods have
sessions enabled. Authenticate authenticates a caller. If the caller is authenticated, Authenticate
generates q unique key, stores that key by using the Session object, and returns that key.
RetrieveData expects a valid key that has been generated by Authenticate as inout before it will return
data. If the key matches the key in the current session, RetrieveData will return data to the customer.
You write the following code segment in the Load event handler of Form1. (Line numbers are
included for reference only)
01 localhost.Service1 service1 = new localhost.Service1();
02 string key = “”;
03 DataSet userData;
04 // Insert new code.
05 key = service1.Authenticate(myUser, myPassword);
06 userData = service1.RetrieveData(key);
07 dataGrid1.DataSource = userData;
You run the application. When line 06 executes the Web service throws an exception, which indicates
that the key is invalid. To ensure that the application runs without exceptions, you must insert
additional code on line 04.
Which code segment should you use?
A. service1.PreAuthenticate = true;
B. service1.InitializeLifetimeService();
C. service1.CookieContainer = new System.Net.CookieContainer();
D. System.Net.Cookie = new System.Net.Cookie(”Key”, key);
Answer: C
Explanation: ASP.NET uses 2 mechanisms to implement sessions: cookies and URL variables. Since it is
impossible to use URL variables in web services, it must be using cookies. In the question, the reason for the

session not functioning properly is that a new cookie is created each time. We need to add a cookie container
to hold the cookie across 2 web service calls. This is verified against MSDN.
QUESTION 2
You are creating an XML Web service that processes credit card information. This service will be
consumed by computers that run on Microsoft Windows operating systems, as well as computers that
run on other operating systems.
You must ensure that client credentials passed to the service are secure and cannot be compromised.
You are not as concerned with the length of time that Web method calls take to maintain this level of
security. You need to configure authentication for this service.
Which type of authentication should you use?
A. Basic
B. Forms
C. Client Certificate
D. Integrated Windows
Answer: C
Explanation: Client certificates can be used on both Windows and non-Windows systems. Client
certificates provide a secure connection.
Note: Client Certificates is used for secure identification of clients in Internet and intranet scenarios. It
requires each client to obtain a certificate from a mutually trusted certificate authority.

[C#]
Incorrect Answers
A: Basic authentication is not secure. Login name and password are transferred unencrypted in clear
text.
B: Forms authentication is not supported by XML Web services. It is a system by which
unauthenticated requests are redirected to an HTML form using HTTP client-side redirection.
D: Integrated Windows authentication can only be used on Windows computers.
QUESTION 3
You are creating an XML Web service named myWebService. This service will be used to exchange
highly confidential information over the Internet with your company’s business partner named
Certkiller , Inc.
You want only callers from Certkiller , Inc., to be able to access myWebService. You do not want to
have to accept a user name and password from callers.
Once callers are authenticated, you want to use Windows user accounts to authorize access to the Web
methods exposed by the Web service. You set up two Windows user accounts named
Certkiller Associate and Certkiller Manager. You need to configure myWebService to meet these
security requirements.
Which type of authentication should you use?

Actualtests.org - The Power of Knowing
A. Basic
B. Digest
C. Anonymous
D. Client Certificate
Answer: D
Explanation: Client certificate authentication meets the requirements of this
scenario:
1. would only allow specific users to gain access
2. no username or password would be required.
Incorrect Answers
A, B: Basic authentication and Digest Authentication would require a user name and a
password from the callers.
C: Anonymous access would allow public access.
