1. You create Web-based client applications. You create a component named Orders for a company named Northwind Traders.
This component is used to retrieve and update data in the Orders table of the company's database. The schema of the Orders table is as shown in the following Exhibit. (Click the Exhibit button.)
The Orders component permits the client application to perform the following tasks:
An instance of the Order class represents a single order that is identified by the OrderID parameter. An instance of the Order class permits the client application to perform the following tasks:
You need to create the design for the component.
What should you do?
To answer, drag the appropriate members to the correct locations in the member type column.
Answer:

2. You create Web-based client applications. You are creating a class named Product. The Product class will be used by a Web-based application to retrieve and modify product information.
When you create an instance of the Product class, you retrieve the current information from the Products table. The Product class contains a static member named CreateNewProduct. The CreateNewProduct method is used to add a new product to the database and return the primary key. The Products table contains the following fields:
You need to create the constructor for the Product class.
Which code segment should you use?
A. public Product(int ProductID, string ProductName, string Description, int CategoryID, decimal CurrentPrice) {
...}
B. public Product(int ProductID, string ProductName) {
...
}
C. public Product() {
...
}
D. public Product(int ProductID)?{
...
}
Answer: D

3. You create Web-based applications. You are creating an Internet banking application. The application will be used by bank account holders.
You are creating a method to withdraw money from an account. The method must change the account balance according to one of the following rules:
You are translating the specification given here into pseudo code. You start by writing the following code.
You need to insert the correct pseudo code.
Which code segment should you insert?
A. If amount < balance then balance - = amount
If amount < balance + 500 then balance = balance - (amount + 35)
If amount > balance + 500 then throw exception
B. If amount <= balance then balance - = amount
If amount <= balance + 500 then balance = balance - (amount + 35)
If amount > balance + 500 then throw exception
C. If amount < balance then balance - = amount
Else If amount < balance + 500 then balance = balance - (amount + 35)
Else throw exception
D. If amount <= balance then balance - = amount
Else If amount <= balance + 500 then balance = balance - (amount + 35)
Else throw exception
Answer: D

4. You create Web-based client applications. You deploy an application on the company extranet. The sales team requires notification when an order total exceeds the company's approval levels.
The application requires you to send an e-mail to the sales manager to receive approval for any order over $100,000. You must meet the following constraints to achieve this requirement:
The design team plans to use the SimpleMailWebEventProvider class of the health monitoring APIs to send the e-mail.
You need to evaluate whether the design meets the requirement.
What should you recommend?
A. The design meets the requirement.
B. The design does not meet the requirement. Though there is a built-in event handler to process all errors, you need to write a custom provider to send e-mail to the sales manager.
C. The design does not meet the requirement. You need to write a custom event handler to respond to an application specific trigger. You can use a built-in provider to send e-mail to the sales manager.
D. The design does not meet the requirement. You need to write a custom event handler to respond to an application specific trigger. You need a custom provider to write e-mail to the sales manager.
Answer: C

Which code segment should you choose?
A. public sealed class OrderDetail {
internal OrderDetail(){
　...
　}
}
B. internal sealed class OrderDetail {
　internal OrderDetail() {
　...
　}
}
C. public sealed class OrderDetail {
　public OrderDetail() {
　...
　}
}
D. public sealed class OrderDetail {
　private OrderDetail() {
　...
　}
}
Answer: A
