Exam MS-600 topic 1 question 23 discussion

HOTSPOT -
You are building a web app that will display the Microsoft Exchange Online Inbox of a user. The app will maintain a copy of the user's Inbox data and regularly check for updates.
You need to configure the Microsoft Graph URI for the app. The solution must minimize network traffic.
How should you complete the request URI? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Suggested Answer:
Box 1: https://graph.microsoft.com/
For Microsoft Graph, apps specify permissions prefixed with https://graph.microsoft.com/. For example, an app can request the Mail.Read permission by including
Box 2: v1.0/me/mailfolders/inbox/messages/delta

API versions -
The Microsoft Graph API offers two versions: v1.0 and beta, while Outlook offers v1.0, v2.0, and beta. Microsoft Graph v1.0 matches Outlook v2.0, and Microsoft
Graph beta matches Outlook beta.

Microsoft Graph -
First, the app has the user sign in to authorize the application. Because the app uses the Microsoft Graph scope Mail.Read, the authorization URL looks like the following: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?scope=openid+Mail.Read&response_type=code&client_id=<SOME
GUID>&redirect_uri=<REDIRECT URL>
Once the app has an access token, it sends the following request: https://graph.microsoft.com/v1.0/me/mailfolders/inbox/messages?$top=1&$select=subject,from,receivedDateTime,isRead

Accept: application/json -
Authorization: Bearer <token>
delta - tracking changes (synchronization)
Both endpoints support querying collections for changes relative to a synchronization state. While the functionality is the same, the methods are slightly different.
On the Microsoft Graph endpoint, changes are queried by using delta queries. This is implemented as a delta function on the collection.
