Case Study -

This is a case study. Case studies are not timed separately. You can use as much exam time as you would like to complete each case. However, there may be additional case studies and sections on this exam. You must manage your time to ensure that you are able to complete all questions included on this exam in the time provided.

To answer the questions included in a case study, you will need to reference information that is provided in the case study. Case studies might contain exhibits and other resources that provide more information about the scenario that is described in the case study. Each question is independent of the other questions in this case study.

At the end of this case study, a review screen will appear. This screen allows you to review your answers and to make changes before you move to the next section of the exam. After you begin a new section, you cannot return to this section.

To start the case study -

To display the first question in this case study, click the Next button. Use the buttons in the left pane to explore the content of the case study before you answer the questions. Clicking these buttons displays information such as business requirements, existing environment, and problem statements. When you are ready to answer a question, click the Question button to return to the question.

Background -

Proseware, Inc. is an industry leading software company with several thousand employees. The company has had some trouble recruiting talented employees. Top-level candidates interview with the company but go on to work for competitors.

Feedback from candidates show that some offers were not accepted because the interview scheduling process was unpleasant. The company does not have a system to keep track of the candidates that were not selected.

Current Environment -

The recruiting process starts when an individual applies for a position on the company website. The individual may have found the position on their own, they may have been officially referred by an employee, or in some cases were contacted directly by a hiring manager and encouraged to apply.

Recruiters schedule an interview with a hiring manager and interviews with two senior team members. Each interview results in feedback about the candidate and a recommendation whether to hire or not.

The recruiting team manages all information by using a model-driven application.

The company has the following Microsoft Dataverse tables and columns:

• JobPosting

- Hiring Manager - lookup to SystemUser

- Recruiter Assigned - lookup to SystemUser

• Contact (Job Applicant)

- Contact identifier

- First name

- Last name

- Time-Zone Offset

- Person of Interest - Yes/No (default)

• Application proapplication

- Contact identifier, Contact - lookup to Contact

- Job Posting - lookup to JobPosting

- pro_recruiterassignedid

• Interview

- Application - lookup to Application

- Job Posting - lookup to JobPosting

- Recommend - Choice (Yes (0), No (1), and null (default) are the available values)

- Person of Interest - Yes/No, No is the default value

• Referral

- Contact - lookup to Contact

- Referrer - lookup to SystemUser

- Job Posting - lookup to JobPosting

• SystemUser

- Manager - lookup to SystemUser

- Time-Zone Offset

• Recruiter

- Recruiter identifier

- Recruiter name

Applications -

There may be multiple applications associated with each job posting. Applications are linked to an employee record if an employee referred the applicant for a position. The same individual can be an applicant for multiple job postings.

Interviews -

Each interview is performed by an employee and is related to a single application.

The interview scheduling process may force potential candidates to accept interviews at unusual times with the senior team members due to time-zone differences.

Requirements. Interview Scheduling

The system must provide recruiters with a list of team members and their time-zone information. You must create a Microsoft Power Apps Component Framework (PCF) control for the Job Application form to display a list of senior team members who report directly to a hiring manager.

The control must display the current time in each team member's local time.
The control must be bound so that it minimizes the amount of code that must be written.
You must display the list of team members and sort the list to show team members who reside in time zones closest to the applicant's time zone first.

You must develop a second PCF control that displays the time-zone name and current time on the Job Application form. You must display the data in the candidate’s local time.

Requirements. Historical Information Tracking

You must create a process to identify individuals as a person of interest that the company should consider hiring. You must assign each individual a score based on their past interactions.

• You must be able to determine the following information about a candidate:

- The number of interviews in the past two years and whether team members provided recommendations

- The number of hiring manager referrals and employee referrals in the past two years

- Whether the individual has any of the 12 designations or certifications that the company considers significant

• Only a single referral can be made per job application. The system must be able to support multiple referrals for a candidate.

• The system must track referrals even if an application is not completed.

Requirements. Historical Information Scoring

The automated process must run weekly to assess all candidates. The process must also run automatically when historical information is updated. You must be able to perform scoring by selecting a command button on the contact form.

• This new command button must only be visible to employees who belong to a security role assigned named Recruiter. The command button must not be visible to anyone unless the contact form is in Update mode.

• A person of interest is defined as having a score of 15 or more based on the following historical information criteria:

- Each interview with a recommendation adds two to the score.

- Each interview without a recommendation subtracts two from the score.

- Each employee or manager referral adds one to the score.

- Each designation or certification adds one to the score.

• All scoring elements must be recalculated when changes occur. You must assign the score to the Person of interest field.

• Values representing totals or scores must be stored in their own numeric fields.

• Plug-ins must be used to keep the Person of Interest field on active interview records associated with the Contact.

• Plug-ins registered on the update of the Person of interest field must send an email notification when the candidate named in the email is a person of interest. Recruiters must receive the message when the field is updated on the Contact record.

• Interviewers must get an email notification when the Person of Interest field on the interview record is successfully updated.

Requirements. Design Guidelines -

The following design guidelines must be followed:

Schema changes must be made using the method requiring the least amount of storage to meet the requirement.
Out-of-the-box functionality must be used when possible.
Any code required to calculate scores must be able to be run from a single point.
Email notifications need to be kept to a minimum.

Issues -

Recruiters report that the command button to score a candidate is not working. You debug the code and observe that the context input parameter is null.
The system does not support associating designations and certifications with candidates.
The value for the field used by the PCF control to display local time is saved to Microsoft Dataverse each time an active application record is opened.
Interviewers report that they do not receive email notifications when interview records are created for an existing person of interest.

You need to resolve the issue with the new command button.

What should you do?

Pass ExecutionContext to the function in the action definition.
Pass the value SelectedControl to the function in the action definition.
Select the Pass execution context as first parameter option on the event registration form.
Pass the value PrimaryControl to the function in the action definition.

Background -

Northwind Traders uses Microsoft Dynamics 365 Sales to manage its sales process. To better understand its customers, Northwind Traders invests in a team of researchers who gather data from multiple sources. The company stores the data it collects in a Microsoft Azure SQL Database. The company plans to use the data to enrich account records and make the sales team more effective.

Current environment -

Environment -

The company has three Microsoft Power Platform environments with Dynamics 365 Sales installed. The environments are named development, test, and production.
Each environment has an application user that can be used for integrations.
The company must use solutions to perform all customization and configuration deployment.

Data -

Researchers are responsible for creating account records.
Researchers have permissions on the Account table to create records, read all records, and update records they own.
A synchronous plug-in runs when an account record is created and could reassign the record to a different user.
Users must access data as themselves to enforce security and audit changes.
A column named new_dataid is added to the Account table. The column uniquely identifies which data it should receive.
Researchers have researched only the top 20 percent of account records.

Web API -

The company creates an Azure Function to run a RESTful .NET Web API.
Data can be retrieved by placing a GET request to the URL https://dataservice-[ENVIRONMENTNAME].azurewebsites.net/enrich/[DATAID].
[ENVIRONMENTNAME] is the name of the Microsoft Power Platform environment that requests the data.
DATAID] is the new_dataid column in the Account table.
The Web API response will return a 200 response plus data if the DataId is found. Otherwise, a 404 response is returned.
Developers plan to create a custom connector from the Web API to make it accessible from Microsoft Power Platform.

Requirements -

Custom connector -

The Web API definition used to create the custom connector must be generated based on a low-code technology.
The URL used by the custom connector must incorporate the current environment name without hardcoding values.
Errors generated by the custom connector must not cause downstream processes to fail.
Text descriptions and field placeholder text that describe the use of the custom connector must appear for non-developers.

Process -

All account records must be updated with data from the Web API once automatically.
Only account records that contain a DataId should be updated by the Web API.
Researchers must create Power Automate flows to specify data analysis priority.
The researchers require a process that repurposes a set of identical steps of parameterized Microsoft Dataverse queries from a Power Automate flow for use in other flows that have different parameters. The researchers want to avoid recreating the steps manually each time they create a flow to save time and avoid errors.

Issues -

A tester attempts to connect to the production instance of the Web API with a DataId that should return data. The tester receives an error stating that the remote name could not be resolved.
A missing component causes an error to occur when importing the solution that contains the Power Automate flow to update account records in a test environment.

You need to determine which component to add to the solution to resolve the account records import error.

Which component should you add?

connection
service endpoint
custom connector
Account table
