What can the developer do to improve the performance?

Question 52

Choose the correct definition for <apex:actionFunction>.

A.Signifies which components should be processed by the server when an AJAX request is generated

B.Adds AJAX support to another component (e.g. onClick, onMouseUp, onFocus, etc.)

C.Allows for controller methods to be called directly from Javascript. Must be encapsulated in <apex:form> tags. Unlike actionSupport, these function<apex:actionPoller>s can be called directly from Javascript code

D.Can be associated with an AJAX request (actionFunction/actionSupport/actionPoller) and shows content conditionally depending on the status of the request (in progress/complete). Use the "id" field to specify name; use "status" field on related components to connect them

E.Sends an AJAX request according to the time interval you specify. If this ever gets re-rendered, it resets

Question 53

Which technique can run custom logic when a Lightning web component is loaded?

A.Call SA.enqueueAction passing in the method to call.

B.Use an aura:handler "init" event to call a function.

C.Use the renderedCallback ( ) method.

D.Use the connectedCallback () method.

Question 54

An Apex trigger creates a Contract record every time an Opportunity record is marked as Closed end Won. This trigger is working great, except (due to a recent acquisition) historical Opportunity records need to be loaded into the Salesforce instance.
When a test batch of records are loaded, the Apex trigger creates Contract records. A developer is tasked with preventing Contract records from being created when mass loading the Opportunities, but the daily users still need to have the Contract records created.
What is the most extendable way to update the Apex trigger to accomplish this?

A.Use a List Custom Setting to disable the trigger for the user who loads the data.

B.Use a Hierarchy Custom Setting to skip executing the logic inside the trigger for the user who loads the data.

C.Add a Validation Rule to the Contract to prevent Contract creation by the user who loads the data.

D.Add the Profile ID of the user who loads the data to the trigger so the trigger will not fire for this user.

Question 55

A developer has created a Team Member sObject that has a Master-Detail relationship to a Project sObject and a Lookup relationship to the User sObject. The developer must ensure that a User listed on a Team Member record has Read-Write access to the parent Project record.
How can the developer accomplish this if the Project sObject has a Private sharing model and thousands of Project records?

A.Create a Criteria-Based Sharing Rule on the Project sObject

B.Create a Team Member Trigger that inserts Project_Share records

C.Create a Project Sharing Rule that shares to the Team Member Group

D.Create a Controller that uses the Without Sharing keyword
