QUESTION 1
You are creating an XML Web service named CKTracker to track orders for your company. Tracker
includes a Web method named OrderStatus for tracguide the status of individual orders. You
anticipate that many client applications will use the service.
You want administrators of CertK Tracker to be able to monitor the requests per second for
OrderStatus.
Which code segment should you use?
A. PerformanceCounter counter = new PerformanceCounter(” CertK Tracker”,
“OrderStatus req/sec”, false);
B. PerformanceCounterCategory.Create(” CertK Tracker”, “category”,
“OrderStatus req/sec”, “req/sec”);
C. CounterCreationData[] counterData = { new CounterCreationData(
“OrderStatus req/sec”, “help”,
PerformanceCounterType.RateOfCountsPerSecond32) };
CounterCreationDataCollection collection = new
CounterCreationDataCollection(counterData);
PerformanceCounterCategory.Create(” CertK Tracker”, “Tracker
performance counters”, collection);
D. CounterCreationData[] counterData = { new CounterCreationData(
“Int32″, “second”, PerformanceCounterType.AverageTimer32) };
CounterCreationDataCollection collection = new
CounterCreationDataCollection(counterData);
PerformanceCounterCategory.Create(“OrderStatus”, “requests per
second”, collection);

QUESTION 2
You are creating an XML Web service named Certkiller Service that processes stock transactions.
Certkiller Service exposed a Web method named BuyStock that takes as input a stock symbol and the
number of shares to buy.
You know that callers who consume this service will require that SOAP messages be formatted as
document-literal SOAP messages or RPC-encoded SOAP messages.
You must create a solution that will return both types of SOAP messages.
You want to accomplish this task by writing the minimum amount of code.
Which code segment should you use?
A. [WebMethod()] public string BuyStock(string symbol, int shares)
B. [SoapDocumentMethod()][WebMethod()] public string BuyStock(string
symbol, int shares)
C. [SoapRpcMethod()][WebMethod()] public string BuyStock(string
symbol, int shares)
D. [SoapDocumentMethod()][WebMethod()] public string
BuyStockDoc(string symbol, int shares)
[SoapRpcMethod()][WebMethod()] public string BuyStockRpc(string
symbol, int shares)
Answer: D
QUESTION 3
You create an XML Web service named AutoPartsService that processes automobile part orders. This
service exposes a Web method named Place CertK Order, which is shown in the following code
segment:
[WebMethod(TransactionOption.RequiresNew)]
public DataSet Place CertK Order(DataSet orderData) {
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 CKPartOrderApp that consumes
AutoPartsService. You run CKPartOrderApp and place and order for three sets of brakes and four
wheels. While Place CertK Order is placing the order for the wheels, you close CKPartOrderApp.
What is the most likely result?

Actualtests.org – The Power of Knowing
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.
Answer: C
Explanation: XML Web Services can only participate in a transaction as the root of a new transaction. the
calls to brakes.OrderBrakes and parts.OrderParts will generate two new different transactions, even if these
two XML Web Services are marked only for TransactionOption.Required! So, if the question says the
CKPartOrderApp is being closed during the order for the wheels, we’ll have the brakes order committed in
brakes.OrderBrakes transaction and wheels order aborted in parts.OrderParts.
Note: XML Web service methods can only participate in a transaction as the root of a new transaction. As
the root of a new transaction, all interactions with resource managers, such as servers running Microsoft
SQL Server, MSMQ, Oracle, and SNA maintain the ACID properties required to run robust distributed
applications. XML Web service methods that call other XML Web service methods participate in different
transactions, as transactions do not flow across XML Web service methods.
