問題4
You are developing an ASP.NET MVC application that will be hosted on Microsoft Azure. The application includes the StackExchange.Redis client package. A variable named CacheConnectionConfiguration stores the cache endpoint URL and the password to connect to the cache.
The application must store a user's color selection by using the Azure Redis cache. The cached value must expire after 90 minutes. You need to cache the user's color selection.
How should you complete the relevant code? To answer, choose the appropriate code segment from each list in the answer area.

How should you complete the relevant code? To answer, choose the appropriate code segment from each list in the answer area.
正確答案:
Explanation:
Box 1: var cache = connection.GetDatabase():
Once the connection is established, return a reference to the redis cache database by calling the ConnectionMultiplexer.GetDatabase method.
Box 2: cache StringSet("color", colorSelection,TimeSpan.FromMinutes(90)); The TimeSpanFromMinutes method returns a TimeSpan that represents a specified number of minutes, where the specification is accurate to the nearest millisecond.
Example: The following code snippet shows how to set an expiration time of 90 minutes on a key.
// Add a key with an expiration time of 90 minutes
await cache.StringSetAsync("data:key1", 99, TimeSpan.FromMinutes(90));

You are developing an ASP.NET MVC application. You plan to use OAuth to authenticate users to the application.
You need to use the correct authentication data in the application.
What should you do? To answer, drag the appropriate data element to the correct location or locations. Each data element may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

正確答案:
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.
