Answer(s): A

Explanation:



Box 1: IsBlank
The IsBlank function tests for a blank value or an empty string. The test includes empty strings to ease app creation since some data sources and controls use an empty string when there is no value present.

Box 2: IsType
The IsType function tests whether a record reference refers to a specific table type.

Box 3: AsType
The AsType function treats a record reference as a specific table type, sometimes referred to as casting. You can use the result as if it were a record of the table and again use the Record.Field notation to access all of the fields of that record. An error occurs if the reference isn't of the specific type.

You are deploying a Power Apps app that uses the custom connector for ServiceNow.
The app loads very slowly for some users. You determine that all records from ServiceNow are being retrieved for every user.
The app must load only incidents that are assigned to each user.
You need to limit the number of records that the connector returns.
What should you do?

  1. Apply a Lifecycle Services asset scope
  2. Apply a business process flow
  3. Apply the Azure APIM parameter
  4. Apply a connector policy template

Answer(s): D

Explanation:

You can configure policy templates for custom connectors. Policies allow you to modify the behavior of a custom connector at runtime. You can use policies to perform data conversion, route requests, set parameter values, and more. You can configure policies directly in the custom connector API properties file before import, or you can do it from the maker portal in the custom connector designer by applying policy templates.
Common policy use cases are:
* Set query parameter - Use for handling default values, if necessary, but the maker doesn't configure one. For example, if an API required a top parameter for how many records to return by using a policy, you could set a default value to be used if the maker doesn't configure one.
Note: ServiceNow Action: GetRecords

Summary: List Records -
Description: Gets records of a certain ServiceNow object type like 'Incidents'
Syntax:ServiceNow.GetRecords (string tableType, [advanced][Optional]booleansysparm_display_value, [advanced][Optional]booleansysparm_exclude_reference_link, [advanced][Optional]string sysparm_query, [advanced][Optional]integer sysparm_limit, [advanced][Optional]integer sysparm_offset)
