Salesforce Platform Developer II 認定 PDII 試験問題 (Q129-Q134):

質問 # 129
A company has a native iOS order placement app that needs to connect to Salesforce to retrieve consolidated information from many different objects in a JSON format.
Which is the optimal method to implement this in Salesforce?

A. Apex SOAP callout
B. Apex REST callout
C. Apex SOAP web service
D. Apex REST web service

正解：D

解説：
Apex REST web services are the best method for creating custom endpoints that return data in a specific format, such as JSON, which is perfect for a native iOS application that needs to integrate with Salesforce for retrieving data.
References: Apex Developer Guide - Exposing Apex Methods as REST Web Services

質問 # 130
For compliance purposes, a company is required to track long-term product usage in their org. The information that they need to log will be collected from more than one object and, over time, they predict they will have hundreds of millions of records.
What should a developer use to implement this?

A. Setup audit trail
B. Big objects
C. Field history tracking
D. Field audit trail

正解：B

解説：
The best way to implement this is to use big objects. Big objects are custom objects that can store and manage massive amounts of data on the Salesforce platform. Big objects can handle hundreds of millions of records and support asynchronous SOQL queries. Big objects are also optimized for performance and scalability, and can be integrated with other Salesforce features such as reports, dashboards, and triggers. Setup audit trail, field audit trail, and field history tracking are not suitable for this scenario, as they have limitations on the number of fields, records, or retention periods that they can track. Reference: [Big Objects], [Trailhead: Big Objects Basics]

質問 # 131
A developer created a Lightning web component that uses a Lightning-record-edit-form to collect information about Leads. Users complain that they only see one error message at a time when they save a Lead record.
Which best practice should the developer use to perform the validations, and allow more than one error message to be displayed simultaneously?

A. Process Builder
B. Client-side validation
C. Custom validation rules
D. Apex REST

正解：C

質問 # 133
Choose the correct definition for <apex:actionRegion>

A. 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
B. Signifies which components should be processed by the server when an AJAX request is generated
C. Sends an AJAX request according to the time interval you specify. If this ever gets re-rendered, it resets
D. 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
E. Adds AJAX support to another component (e.g. onClick, onMouseUp, onFocus, etc.)

正解：B
