You create an XML Web service named LatLong that converts street addresses to latitude and
longitude coordinates. Company Inc. charges for this service and allows only existing customers
to use the service. If a customer ID is not passed as part of a SOAP header, you want the service
to refuse the request. You want these service refusal messages to be logged to an event log
named LatLong Log. You anticipate that there will be a lot of these log entries over time. A string
object named refusal Message contains the message to log.
Which code segment should you use?
A. Event log = new EventLog("LatLong Log"); log.WriteEntry(refusal Message,
EventLogEntryType.Error);
B. EventLog log = new EventLog(); log.Source = "LatLong Log"; log.WriteEntry(refusal Message,
EventLogEntryType.Error);
C. if (!EventLog.SourceExists("LatLongSource")) {
EventLog.CreateEventSource("LatLongSource","LatLongLog");}
EventLog.WriteEntry("LatLongSource", refusal Message, EventLogEntryType.Error);
D. if (!EventLog.SourceExists("LatLongSource"))
{EventLog.CreateEventSource("LatLongSource","LatLongLog"; }EventLog log = new
EventLog("LatLong
Log"); log.WriteEntry(refusal Message, EventLogEntryType.Error);

You are creating an XML Web service that processes highly confidential messages. The service
exposed a Web method named Retrieve Message that takes as input a code name and returns
an encrypted message. You create a SOAP extension and override the extension's Process
Message method so that you can encrypt the message before it is sent back to the caller. You
need to encrypt only the data within the RetrieveMessageResult node of the SOAP response.
You create a function named Encrypt Message that encrypts the RetrieveMessageResult node.
You need to ensure that this method gets called before sending the message back to the caller.
During which SoapMessageStage should you call Encrypt Message?
A. Before Serialize
B. After Serialize
C. Before Deserialize
D. After Deserialize

You create an XML Web service named AutoPartsService that processes automobile part orders.
This service exposes a Web method named PlaceExamSOrder, which is shown in the following
code segment:
[WebMethod(TransactionOption.RequiresNew)] public DataSet
PlaceExamSOrder(DataSetorderData) {
Server1.BrakesService brakes = new Server1.BrakesService();
Server2.PartsService parts = new Server2.PartsService(); // Call OrderBrakes to order only
brakes.
brakes.OrderBrakes(orderData.
Tables["Brakes"]); // Call OrderParts to order all other auto parts. parts.OrderParts(orderData.
Tables["Parts"]);
}
BrakesService and PartsService are XML services. The TransactionOption property of
OrderBrakes and
OrderParts is set to TransactionOption.Required.
You develop a Windows Forms application named ESPartOrderApp that consumes
AutoPartsService. You run
ESPartOrderApp and place and order for three sets of brakes and four wheels. While
PlaceExamSOrder is
placing the order for the wheels, you close ESPartOrderApp.
What is the most likely result?
A. OrderParts stops processing the order, and all orders are cancelled.
B. OrderParts continues processing the order, and all orders are placed.
C. OrderParts stops processing the order, the brakes are ordered, but the wheels are not
ordered.
D. OrderParts stops processing the order, the brakes are not ordered, but the wheels are
ordered.

Company Ltd. receives product information from manufactures in the form of an XML documents.
The product information is stored in a Microsoft SQL Server database. The format of each XML
document varies. Each one is located in a MemoryStream object named newProds. You create a
merge procedure that reads data and schema information in a Dataset object and merges the
information into your database. You now need to write code to transfer the XML document and its
schema into a Dataset object.
Which code segment should you use?
A. Dataset products = new Dataset("prodInfo");
XmlTextReader reader = new XmlTextReader(newProds);
XmlValidatingReader validReader = new
XmlValidatingReader(reader);
while (validReader.Read()) { products.WriteXml(validReader.Value);}
B. Dataset products = new Dataset("prodInfo");
products.ReadXml(newProds);
C. Dataset products = new Dataset("prodInfo");
XmlDataDocument document = new XmlDataDocument(products);
D. document.DataSet.ReadXmlSchema(newProds);
Dataset products = new Dataset("prodInfo");
string myXmlData = Encoding.UTF8.GetString(newProds.ToArrary());
SqlDataAdapter adapter = new SqlDataAdapter("LoadSchemaType=XML",myXmlData);
adapter.
Fill(products)

You are creating an XML Web service that provides a daily quotation from literary works to its
customers. This quotation is requested in many different languages, thousands of times every
day, and by thousands of Web sites operating many different platform. A Web method named
GetCompanyQuotes takes a languageID as input. GetCompanyQuotes uses this language ID to
retrieve a translated version of the daily quotation from a Microsoft SQL Server database and to
return that quotation to the customer. You want to minimize the time it takes to return the
translated version.
What should you do?
A. Store each translated quotation by using the Cache object.
B. Store each translated quotation by using the Session object.
C. Set the Buffer Response property of the WebMethod attribute to false.
D. Set the Cache Duration property of the WebMethod attribute to an interval greater than zero. |

You are creating an ASP.NET application named CompanyWebApp. To CompanyWebApp, you
add a Web reference to an XML Web service named User Service. User Service consists of a
Web method named RetrieveUserInfo. This Web method takes a userID as input and returns a
DataSet object containing user information. If the userID is not between the values 1 and 1000, a
System Argument Exception is thrown. In CompanyWebApp, you write a try/catch block to
capture any exceptions that are thrown by User Service. You invoke RetrieveUserInfo and pass
1001 as the user ID.
Which type of exception will be caught?
A. System.ApplicationException
B. System.ArgumentException
C. System.Web.Service.Protocols.SoapException
D. System.Web.Service.Protocols.SoapHeaderException
