A company plans to create an order processing app. When orders are created, the app will perform complex business logic and integrate with several external systems.
Orders that have a large number of line items may take up to six minutes to complete. Processing for each order must be completed in one operation to avoid leaving records in an incomplete state.
You need to recommend a solution for the company.

You create a suite of Power Platform-based order management canvas apps for a bakery that has five retail stores. Each store uses a tablet device to manage inventory and process orders.
You need to make the following changes to the original order tracking app:
* When an online order for delivery is received, send the order to the bakery that is located closest to the order destination.
* When an online order for pickup is received, require store staff to enter an estimated time in an app.
Staff must prepare the order and then use the app to notify the customer when the order is ready.
* Allow the store manager to personalize the company's corporate weekly newsletter and add store- specific specials.
You must minimize the amount of custom code and configuration required to implement the solution.
What should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Box 1: Custom self-service portal for both employers and job candidates If you select an environment that contains customer engagement, you can create the following portals:
Customer self-service portal: A customer self-service portal enables customers to access self-service knowledge, support resources, view the progress of their cases, and provide feedback.
Partner portal: A partner portal allows every organization with resellers, distributors, suppliers, or partners to have real-time access to every stage of shared activities.
Employee self-service portal: An employee self-service portal creates an efficient and well-informed workforce by streamlining common tasks and empowering every employee with a definitive source of knowledge.
Box 2: Model-driven app with push notifications
Compared to canvas apps, model-driven apps in PowerApps are based on underlying data - specifically, the data stored in Common Data Service (CDS).
Box 3: Webform with target set to the job custom entity
Box 4: Configure a value for the Execute Workflow on Redeeming Contact option only.
Execute Workflow on Redeeming Contact: A workflow process to be executed when the invite is redeemed.
The workflow will be passed the redeeming contact as the primary entity.
Box 5: Configure the value for the Assigned to Account option only.
Assign to Account: An account record to be associated as the redeeming contact's parent customer when the invite is redeemed.

Explanation:
Box 1: IsOptimisticConcurrencyEnabled
On a multi-threaded and multi-user system like Power Apps, operations and data changes often happen in parallel. A problem arises when two or more update or delete operations on the same piece of data happen at the same time. This situation could potentially result in data loss. The optimistic concurrency feature provides the ability for your applications to detect whether a table record has changed on the server in the time between when your application retrieved the record and when it tries to update or delete that record.
Box 2: If-Match: Etag
Use If-Match and If-None-Match headers with ETag values to check whether the current version of a resource matches the one last retrieved, matches any previous version or matches no version. These comparisons form the basis of conditional operation support. Dataverse provides ETags to support conditional retrievals, optimistic concurrency, and limited upsert operations.

Fabrikam, Inc, has two divisions as shown in the Business Unit exhibit. (Click the Business Unit tab.)
* Fabrikam Residences rents units short term to clients.
* Fabrikam Property Management deals with the maintenance of the units and manages the contractors who perform the maintenance.
* Clients and contractors are both stored in the Contact entity.
The manager of the Property Management business unit is a member of a Fabrikam business unit, which has the root security role as shown in the Security Role exhibit. (Click the Security Role tab.)
The manager cannot see the contact record shown in the Contact exhibit. (Click the Contact tab.)
You need to ensure that the manager can view contact records owned by someone in the Residences business unit.
For each of the following statements, select Yes if the statement achieves the goal. Otherwise, select No.

Box 1: Yes
Change it to Direct User/Basic access level and Team privileges. This creates a security role with team member's privilege inheritance.
Note: For roles assigned to teams with Basic-level access user privilege, the role's inheritance configuration also comes into play. If the team has the Member's privilege inheritance set to Team privileges only, then the user will only be able make use of that privilege for records owned by the team.ยจ
Box 2: No
The manager of the Property Management business unit is already a member of a Fabrikam business unit, which has the root security role Box 3: Yes Reference:

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than once correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are designing a one-way integration from the Common Data Service to another system.
You must use an Azure Function to update the other system. The integration must send only newly created records to the other system. The solution must support scenarios where a component of the integration is unavailable for more than a few seconds to avoid data loss.
You need to design the integration solution.
Solution: Register a service endpoint in the Common Data Service that connects to an Azure Service Bus queue.
Register a step at the endpoint which runs asynchronously on the record's Create message and in the portoperation stage.
Configure the Azure Function to process records as they are added to the queue.

A company develops a model-driven app. The company sets up a custom form for the Contact table. The app contains multiple custom app pages.
You must extend the app as follows:
* Run logic when a contact is saved.
* Display data from an Azure SQL Server database.
* Apply a consistent header across multiple app pages.
* Run a Dataverse custom API when the Contact row is saved.
You need to implement the app extension by using minimal development effort.
What should you implement for each requirement? To answer, move the appropriate capabilities to the correct requirements. You may use each capability once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content.

Explanation:
Box 1: Option Set
Box 2: Date only
When team members create tournament records they must enter the start date for a tournament. The end date of the tournament must be automatically calculated.
Box 3: Lookup
Customer information is stored in the Accounts entity. Each tournament record must list the associated sales representative as the tournament owner.
Note: When you create a new lookup column you are creating a new Many-to-One (N:1) table relationship between the table you're working with and the Target Row Type defined for the lookup. There are additional configuration options for this relationship that are described in Create and edit relationships between tables.
But all custom lookups can only allow for a reference to a single row for a single target row type.
