Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: Yes
Delta query lets you query for additions, deletions, or updates to users, by way of a series of delta function calls. Delta query enables you discover changes to users without having to fetch the entire set of users from Microsoft Graph and compare changes.

Box 2: No
Tracking user changes
Tracking user changes is a round of one or more GET requests with the delta function. You make a GET request much like the way you list users, except that you include the following:

The delta function.
A state token (deltaToken or skipToken) from the previous GET delta function call.

Delta tokens are only valid for a specific period before the client application needs to run a full synchronization again. For directory objects (application, administrativeUnit, directoryObject, directoryRole, group, orgContact, oauth2permissiongrant, servicePrincipal, and user), the limit is 7 days.

Box 3: No
There is limited support for $filter:
The only supported $filter expression is for tracking changes on a specific object: $filter=id+eq+{value}. Box 4: Yes

DRAG DROP (Drag and Drop is not supported)
You are developing a Power Platform app for a school. The school plans to use the app to gather information about classes and students.
You must design a plug-in for the app. You must store data about students in the Contacts table and store data about classes in a custom table.
You need to select the stage in the event pipeline for each function.

Which stages should you use? To answer, drag the appropriate plug-in stages to the correct functions. Each plug-in stage 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.

NOTE: Each correct selection is worth one point.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: PreValidation
For the initial operation, this stage will occur before the main system operation.
This provides an opportunity to include logic to cancel the operation before the database transaction.

Box 2: PreOperation
Occurs before the main system operation and within the database transaction.
If you want to change any values for an entity included in the message, you should do it here.
Avoid cancelling an operation here. Canceling will trigger a rollback of the transaction and have significant performance impact.

Box 3: PostOperation
Occurs after the main system operation and within the database transaction.
Use this stage to modify any properties of the message before it is returned to the caller.

The communication department for a company plans to add a publicly accessible survey page to the company's public website.
You must add the new survey page to the company's public website and capture data from the page to a Common Data Service environment.
Explicit user credentials must not be required to write survey data to Common Data Service.
You need to implement authentication.
Which authentication mechanism should you implement?

  1. ADFS
  2. Azure AD Conditional Access
  3. OAuth 2.0
  4. Client secret

Answer(s): C

Explanation:

The OAuth 2.0 client credentials grant flow permits a web service (confidential client) to use its own credentials, instead of impersonating a user, to authenticate when calling another web service.
Note: OAuth is the preferred means to authenticate because it provides access to both the OData RESTful web services (Web API and OData global Discovery service) as well as to the SOAP web services (Organization service and Discovery service).
OAuth is also required to support:
-Azure Active Directory configurations for conditional access, such as Two-factor Authentication (2FA)
-Use of client secrets to enable server-to-server authentication scenarios.
-Cross-Origin Resource Sharing (CORS) to connect a Single-page Application (SPA)
