NEW QUESTION # 98
As part of the month-end financial closing process, a company uses a batch job to copy all orders into a staging database.
The staging database is used to calculate any outstanding amounts owed by clients, and must process all historical data.
You need to ensure that only the data affected during the month is included in the integration process.
What are two possible ways to achieve this goal? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
- A. Create a system view with the orders that have the Modified On field in the last month and run the integration on this subset.
- B. Create a system view with the order lines that have the Modified On field in the last month and run the integration on this subset.
- C. Use change tracking on the orders and run the integration to retrieve new orders and the orders that have the total amount changed in the last month.
- D. Use change tracking on the order lines and run the integration every week and retrieve only the order lines that have been created or deleted in the last month.
Answer: B,D
Explanation:
Explanation
C: The change tracking feature in Microsoft Dataverse provides a way to keep the data synchronized in an efficient manner by detecting what data has changed since the data was initially extracted or last synchronized.
Deletions and creations are tracked.
D: On modified Order Lines, not on Modified Orders.

NEW QUESTION # 99
You work for a multinational company that has Azure and Common Data Service environment in the United States (UTC-7) and Japan (UTC+9).
You create Azure Functions for each location to update key data.
You need to configure the functions to run at 4:00 AM on weekdays at each location.
Which schedule formats should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation
Box 1: 0 0 4 * * 1-5
Azure Functions uses the NCronTab library to interpret NCRONTAB expressions.
An NCRONTAB expression is similar to a CRON expression except that it includes an additional sixth field at the beginning to use for time precision in seconds:
{second} {minute} {hour} {day} {month} {day-of-week}
NCRONTAB time zones
The numbers in a CRON expression refer to a time and date, not a time span. For example, a 5 in the hour field refers to 5:00 AM, not every 5 hours.
The default time zone used with the CRON expressions is Coordinated Universal Time (UTC).
To have your CRON expression based on another time zone, create an app setting for your function app named WEBSITE_TIME_ZONE.
1-5 is weekdays

NEW QUESTION # 101
An online store has a custom web page that allows customers to place their orders against a Microsoft Dataverse database that uses custom products. The custom web page uses Web API patterns to create and update records.
Customers report that orders can be placed for out-of-stock items.
You need to update the page code to ensure that inventory is available before confirming an order.
Which pattern should you use for each step? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
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.

NEW QUESTION # 108
A company uses Common Data Service rollup fields to calculate insurance exposure and risk profiles for customers.
Users report that the system does not update values for the rollup fields when new insurance policies are written.
You need to recalculate the value of the rollup fields immediately after a policy is created.
What should you do?
- A. Change the frequency of the Calculate Rollup Field recurring job from every hour to every five minutes.
- B. Create new fields on the customer entity for insurance exposure and risk. Write a plug-in that is triggered whenever a new policy record is created.
- C. Update the Mass Calculate Rollup Field job to trigger when a new policy record is created.
- D. Create a plug-in that uses the update method for the rollup field. Configure a step on the Create event for the policy entity for this plug-in.
Answer: A
Explanation:
Explanation
As a system administrator, you can modify the rollup job recurrence pattern, postpone, pause, or resume the rollup job.
To pause, postpone, resume, or modify the recurrence pattern, you must view the system jobs. More information View Rollup jobs On the nav bar, choose Actions and select the action you want.
For the Calculate Rollup Field job, the available selections are: Modify Recurrence, Resume, Postpone, and Pause.
For the Mass Calculate Rollup Field job, the available selections are: Resume, Postpone, and Pause.
Note: Calculate Rollup Field is a recurring job that does incremental calculations of all rollup columns in the existing rows for a specified table. There is only one Calculate Rollup Field job per table. The incremental calculations mean that the Calculate Rollup Field job processes the rows that were created, updated, or deleted after the last Mass Calculate Rollup Field job finished execution. The default maximum recurrence setting is one hour. The job is automatically created when the first rollup column on a table is created and deleted when the last rollup column is deleted.

NEW QUESTION # 110
You are building a custom application in Azure to process resumes for the HR department.
The app must monitor submissions of resumes.
You need to parse the resumes and save contact and skills information into the Common Data Service.
Which mechanism should you use?
- A. Custom workflow activity
- B. Power Automate
- C. Web API
- D. Common Data Service plug-in
Answer: B
Explanation:
Improve operational efficiency with a unified view of business data by creating flows that use Dataverse (Common Data Service has been renamed to Microsoft Dataverse as of November 2020).
For example, you can use Dataverse within Power Automate in these key ways:
Create a flow to import data, export data, or take action (such as sending a notification) when data changes.
Instead of creating an approval loop through email, create a flow that stores approval state in an entity, and then build a custom app in which users can approve or reject items.
