You are a Dynamics 365 developer working on a model-driven app.
You add a button to an entity form and to the view for the entity that calls a JavaScript function. When you click the button, it results in an error.
You determine that the JavaScript function is calling another JavaScript function in a different web resource.
You need to resolve the error.
What should you do?
Answer:
A
Web resource dependencies -
You can define dependencies between other web resources. The primary purpose of this feature is to allow association of String (RESX) web resources with the
JavaScript web resources that will use them. This is also the way that web resources required by HTML web resources for use offline can be configured to also be available offline.
Within a solution you can define dependencies within solution components. Up until Mode-driven Apps the main purpose of these dependencies was to prevent the deletion of a solution component when another solution component depended on it. With Model-driven apps the behavior for JavaScript web resources is enhanced so that any other web resource listed as a dependency to the JavaScript web resource will be loaded along with the JavaScript web resource.
Incorrect:
Not B: &ribbondebug=true is used for debugging.
Not C: When configuring ribbon elements, you can define specific rules to control when the ribbon elements are enabled.
Custom Rule uses the <CustomRule> element. Use this kind of rule to call a function in a Script (JScript) web resource that returns a Promise (Unified Interface) or boolean (Unified Interface and web client).

A multinational company requires that all phone numbers be standardized as country code + area code + phone number.
The application design team decides that a custom Power Apps component framework (PCF) control should be used to prompt users for an area code and to correctly format the phone number.
You need to get the list of valid area codes when a contact record is opened and before the user enters a new phone number.
In which function should you call webAPI.retrieveMultipleRecords?
Answer:
A
The updateView method will be called when any value in the property bag has changed. This includes field values, data-sets, global values such as container height and width, offline status, component metadata values such as label, visible, etc.
Note: webAPI.retrieveMultipleRecords retrieves a collection of entity records.
Incorrect Answers:
notifyOutputChanged is a callback method to alert the framework that the control has new outputs ready to be retrieved asynchronously. getOutputs is called by the framework prior to a component receiving the new data. Returns an object based on nomenclature defined in manifest, expecting objects[s] for the property marked as bound.

You are examining code written by another developer that is not functioning correctly. There are no other JavaScript or business rules in use on the form.
This code is properly registered to the OnChange event of the telephone1 field on an account entity form. The main operation is to update the primary contact's phone number when the account phone number changes. The primary contact field is a lookup. (Line numbers are included for reference only.)

Problem patterns: Web-use-async -
There are multiple ways to interact with the server or request resources. Common approaches that allow for synchronous communications include the following
(These scenarios should be avoided.):
✑ Usage of the XMLHttpRequest object passing in false for the value of the async parameter for the open function call var requestXhr = new XMLHttpRequest();
// Explicitly setting the async parameter to false or supplying a variable with a value of false will force this as a synchronous call. requestXhr.open('GET', '/test/test.txt', false);

Answer:
Box 1: Functions -
most functions and services that are stateless and do not have side effects.
Box 2: Actions -
Actions can have side effects.
Box 3: Complex types -
Complex types -
Complex types are keyless named structured types consisting of a set of properties. These are value types whose instances cannot be referenced outside of their containing entity. Complex types are commonly used as property values in an entity or as parameters to operations.
Incorrect:
* An entity type is a named structured type with a key. It defines the named properties and relationships of a table.
* Enumeration types are named primitive types whose values are named constants with underlying integer values.
Type definitions are named primitive types with fixed facet values such as maximum length or precision. Type definitions can be used in place of primitive typed properties, for example, within property definition

You are developing an app that uses Common Data Service.
You must integrate Common Data Service with a new web application. You must allow the new web application to display data from Common Data Service.
You build a single-page web application using the Web API.
You need to authenticate your app using OAuth.
What should you use?
Answer:
B
You can create a Single-Page Application (SPA) which uses JavaScript to work with Microsoft Dataverse (Common Data Service) data. To provide this, Cross-
Origin Resource Sharing (CORS) is enabled so that your SPAs can bypass browser restrictions that normally prevent requests that cross domain boundaries.

A company has a model-driven app.
A custom button on a form calls a JavaScript function that validates form data fields and creates a web basket. The JavaScript function then displays a message to the user.
Users are located in the United States, which uses ISO Code 1033, and France, which uses ISO Code 1036.
Users in France report that the message displays in English.
You need to modify the RibbonDiffXml file to ensure that messages appear in the user's language.

Answer:
Box 1: CrmParameter -
In addition to data values, you can retrieve client context information by using <CrmParameter>. You can use the following options as the value for the
CrmParameter element: OrgName, OrgLcid, and UserLcid.
Box 2: UserLcid -
userLCID is the language code of the current user.
Note: A locale is a set of user preference information related to the user's language. The locale determines how dates, times, currencies, and numbers are formatted, how items are alphabetically sorted, and how strings are compared. The locale identifier (LCID) is a 32-bit value that uniquely defines a locale.
