You are developing an ASP.NET Core MVC web application. The landing page of the application contains over 100 small JPEG images, including many images that have embedded Mobile device users report performance issues when loading the landing page. You debug the application and determine that the number of HTTP requests is causing the issue.
You need to improve the performance of the landing page.
Solution: Convert all images to JPEG with a high compression ratio.

You are building an ASP.NET application. You develop the following unit test code. Line numbers are included for reference only.
01 [TestClass]
02 public class UnitTest1
03 {
04 protected string _name;
05 protected float _expenses;
06 protected float _income;
07 protected float _payment;
08 protected float _balance;
09 public void AddCustomer(string name, float income, float payment, float balance)
10 {
11 _name = name;
12 _expenses = expenses;
13 _income = income;
14 _payment = payment;
15 _balance = balance;
16 CheckName();
17 DebRatio();
18 CheckBalance();
19 }
20 [TestMethod]
21 public void CheckName()
22 {
23 Assert.IsNotNull(_name, "CheckName failed unit test");
24 }
25 [TestMethod]
26 public void DebRatio()
27 {
28 Assert.AreSame(_income, _payment, "DebRatio failed unit test");
29 }
30 [TestMethod]
31 public void CheckBalance()
32 {
33 Assert.IsTrue(_balance >= 0.0f, Check balance failed unit test.");
34 }
35}
You run the following line of code:
AddCustomer("Contoso", 0, 100, 100, -1);
You need to evaluate the unit test results. For each of the following statements, select Yes if the statement is true. Otherwise, select No.

You run the following line of code:
AddCustomer("Contoso", 0, 100, 100, -1);
You need to evaluate the unit test results. For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Correct Answer:
Explanation:
Box 1: Yes
Line 23 is Assert.IsNotNull(_name, "CheckName failed unit test");
_name is "Contoso" so the assertion will succeed.
Box 2: No
Line 289 is Assert.AreSame(_income, _payment, "DebRatio failed unit test");
_income is 0 and payment is 100. The assertion will fail.
Box 3: No
Line 33 is Assert.IsTrue(_balance >= 0.0f, Check balance failed unit test.");
_balance is -1. The assertion will fail.
You are developing a Microsoft Azure ASP.NET Core web application named onlinestore.
Users report bugs with the web application that only occur on development deployments. The bugs are in a third-party component.
You need to gather a memory dump of the running application to provide to the component vendor.
How should you construct the URI to gather the memory dump? To answer, drag the appropriate URI segments to the correct locations. Each URI segment may be used once, more than once, or mot at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

You are developing an ASP.NET MVC application in Visual Studio 2012. The application supports multiple cultures.
The application contains three resource files in the Resources directory:
Each file contains a public resource named Currency with the localized currency symbol. The application is configured to set the culture based on the client browser settings.
The application contains a controller with the action defined in the following code segment. (Line numbers are included for reference only.)
You need to set ViewBag.LocalizedCurrency to the localized currency contained in the resource files.
Which code segment should you add to the action at line 03?

Correct Answer:
Explanation:
Live Connect implements the OAuth 2.0 protocol to authenticate users.
In the authorization code grant flow, the client makes authorization requests by using request_type=code.
The following diagram illustrates how the authorization code grant flow works.
1. The client starts the flow by directing the resource owner's user agent to the Live Connect authorization endpoint, by using a URL in the following format.
https://login.live.com/oauth20_authorize.srf?client_id=CLIENT_ID&scope=SCOPES&response_type=code&redirect_uri=REDIRECT_URI
2. The authorization server authenticates the resource owner via the user agent, and establishes whether the resource owner grants or denies the client's access request.
3. Assuming that the resource owner has granted access, the Live Connect authorization server redirects the user agent to the client by using the redirection URI that was provided in the initial request.
4. The user agent calls the client with the redirection URI, which includes an authorization code and any local state that was provided by the client. For example: http://contoso.com/Callback.htm?code=AUTHORIZATION_CODE.
5. The client requests an access token from the authorization server's token endpoint by using its client credentials for authentication, and includes the authorization code that was received in the previous step.
6. If the credentials are valid, the authorization server responds by returning an access token.
