Consider the following code snippet:
HTML
<c-selected-order>
<template for:each={orders.data} for:item="order">
<c-order orderId={order.Id}></c-order>
</template>
</c-selected-order>
How should the <c-order> component communicate to the <c-selected-order> component that an order has been selected by the user?

• A.Create and fire an application event.
• B.Create and fire a component event.
• C.Create and fire a standard DOM event.
• D.Create and dispatch a custom event.

The CalloutUtil.makeRestCallout fails with a 'You have uncommitted work pending. Please commit or rollback before calling out' error. What should be done to address the problem?
Java
public void updateAndMakeCallout(Map<Id, Request__c> regs, Map<Id, Request_Line__c> regLines) { Savepoint sp = Database.setSavepoint(); try { insert regs.values(); insert regLines.values(); HttpResponse response = CalloutUtil.makeRestCallout(regs.keySet(), regLines.keySet());
} catch (Exception e) {
Database.rollback(sp);
}
}

• A.Remove the Database.setSavepoint and Database.rollback.
• B.Move the CalloutUtil.makeRestCallout method call below the catch block.
• C.Change the CalloutUtil.makeRestCallout to an @InvocableMethod method.
• D.Change the CalloutUtil.makeRestCallout to an @future method.

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

• A.Use the renderedCallback() method.
• B.Use the connectedCallback() method.
• C.Call $A.enqueueAction and pass in the method to call.
• D.Use an <aura:handler> init event to call a function.

Given the following code:
Java
for ( Contact c : [SELECT Id, LastName FROM Contact WHERE CreatedDate = TODAY] )
{
Account a = [SELECT Id, Name FROM Account WHERE CreatedDate = TODAY LIMIT 5]; c.AccountId = a.Id; update c;
}
Assuming there were 10 Contacts and five Accounts created today, what is the expected result?

• A.System.QueryException: List has more than one row for Assignment on Account
• B.System.LimitException: Too many SOQL Queries on Contact
• C.System.QueryException: Too many DML Statement errors on Contact
• D.System.LimitException: Too many SOQL Queries on Account

A developer is debugging an Apex-based order creation process that has a requirement to have three savepoints, SP1, SP2, and SP3 (created in order), before the final execution of the process. During the final execution process, the developer has a routine to roll back to SP1 for a given condition. Once the condition is fixed, the code then calls a roll back to SP3 to continue with final execution. However, when the roll back to SP3 is called, a runtime error occurs. Why does the developer receive a runtime error?

• A.The developer should have called SP2 before calling SP3.
• B.The developer used too many savepoints in one trigger session.
• C.The developer has too many DML statements between the savepoints.
• D.SP3 became invalid when SP1 was rolled back.
