   Answer: ACE

   Explanation

   Correct: It's E, then C, then A (in that order), but before doing A, rerun the task where the plugin fails. Then you have the image that you can replay as many times as you like while debugging (A).

   Answer: See figure below

   Explanation

   Box 1: create - An error message must display if customers enter data incorrectly. The message must be created - Box 2: contact - Customers are allowed to add up to three countries/regions to their travel preferences from the website. Their preferences must be stored in the Contact entity. Box 3: region - Customers are allowed to add up to three regions to their travel preferences from the website. Customer preferences must be stored in the Contact entity Box 4: synchronous - A synchronous plug-in will cause the operation to wait until the code in the plug-in completes. This has an impact on perceived performance of the system. The operations in an asynchronous plug-in are placed in a queue and are executed after the operation is completed so that the operation can complete with minimal interruption.

   Answer: See figure below

   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 Box 2: 0 0 4 * * 1-5 - Reference: https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer ?

   Explanation

   Box 1: PreValidation - 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: Synchronous - Ideally, you should only cancel operations using synchronous plug-ins registered in the PreValidation stage. Box 3: Pre Image - Box 4: throw .. When you throw an InvalidPluginExecutionException exception within a synchronous plug-in an error dialog with your message will be displayed to the user.

   Answer: See figure below

   Explanation

   Box 1: Lookup - The LookUp function finds the first record in a table that satisfies a formula. Use LookUp to find a single record that matches one or more criteria. Besides the normal formula operators, you can use the in and exactin operators for substring matches. [!INCLUDE [record-scope]../../includes/record-scope.md)] Example: Filter(IceCream, OnOrder > 0) - Returns records where OnOrder is greater than zero. Box 2: Global choice and Lookup - Box 3: Global choice - A choice column provides a list of values for users to pick from. They help streamline data entry in turn ensuring clean data. There are two types - local and global. Local choices can are local to the table and column that they are created for. They cannot be reused on other tables. For example, a list of statuses for an application may not apply anywhere else (e.g. Submitted, In Review, Approved, Rejected). On the other hand, global choices are available across all tables and columns allowing them to be reused.
