Salesforce Platform Developer II Sample Questions (Q17-Q22):

NEW QUESTION # 17
Refer to the code below:
Lightning Web Component JS file
JavaScript
import {LightningElement} from 'lwc';
import serverEcho from '@salesforce/apex/SimpleServerSideController.serverEcho'; export default class Helloworld extends LightningElement { firstName = 'world'; handleClick() { serverEcho({ firstName: this.firstName
})
.then((result) => {
alert('From server: ' + result);
})
.catch((error) => {
console.error(error);
});
}
}
Apex Controller
Java
public with sharing class SimpleServerSideController {
@AuraEnabled
public static String serverEcho(sObject firstName) {
String firstNameStr = (String)firstName.get('firstName');
return ('Hello from the server, ' + firstNameStr);
}
}
Given the code above, which two changes need to be made in the Apex Controller for the code to work?

A. Change the method signature to be global static, not public static.
B. Remove line 06 from the Apex Controller and instead use firstName in the return on line 07.
C. Annotate the entire class as @AuraEnabled instead of just the single method.
D. Change the argument in the Apex Controller line 05 from sObject to String.

Answer: B,D

Explanation:
The current Apex controller implementation contains a type mismatch between the data being sent from the JavaScript controller and the data type expected by the Apex method. In the JavaScript file, this.firstName is initialized as the string 'world'. When the serverEcho method is invoked, it passes this string value under the key firstName.
In the Apex Controller, the parameter is incorrectly defined as an sObject. Because the JavaScript is passing a simple string, the Apex method signature must be updated to accept a String (Option B). Consequently, line
06-which attempts to use the .get() method (a method specific to sObjects)-is no longer valid and should be removed. Instead, the developer should directly use the firstName variable in the return statement (Option C).
Option A is incorrect because @AuraEnabled is a method-level annotation, not a class-level one. Option D is incorrect because public static is the sufficient and standard access modifier for Apex methods exposed to Lightning components; global is only necessary if the component resides in a different namespace (such as in a managed package). By aligning the data types between the two layers, the serialization process can correctly map the JavaScript string to the Apex string variable.

NEW QUESTION # 18
A developer needs to implement a system audit feature that allows users, assigned to a custom profile named "Auditors", to perform searches against the historical records in the Account object. The developer must ensure the search is able to return history records that are between 12 and 24 months old.
Given the code below, which select statement should be inserted below as a valid way to retrieve the Account History records ranging from 12 to 24 month old?
A)

B)

C)

D)

A. Option D
B. Option B
C. Option A
D. Option C

Answer: C

NEW QUESTION # 19
Developer wishes to improve runtime performance of Apex calls by caching results on the client. What is the best way to implement this?

A. Decorate the server-side method with @AuraEnabled(cacheable=true).
B. Decorate the server-side method with @AuraEnabled(storable=true).
C. Set a cookie in the browser for use upon return to the page.
D. Call the setStorable() method on the action in the JavaScript client-side code.

Answer: D

NEW QUESTION # 20
Part of a custom Lightning component displays the total number of Opportunities in the org, which are in the millions. The Lightning component uses an Apex method to get the data it needs. What is the optimal way for a developer to get the total number of Opportunities for the Lightning component?

A. SOQL for loop that counts the number of Opportunities records
B. Apex batch job that counts the number of Opportunity records
C. SUM () SOQL aggregate query on the Opportunity object
D. COUNT () SOQL aggregate query on the Opportunity object

Answer: D

Explanation:
When you need to retrieve the total count of records in a large dataset (millions of records), a SOQL aggregate query using COUNT() (Option A) is the most efficient and performant method. Salesforce optimizes aggregate functions at the database 13level. Unlike a standard query that returns in14dividual records and counts against the "50,000 SOQL rows" limit, a COUNT() query returns a single integ15er result and counts as only one row to16ward the governor limits.17 This allows a developer to count millions of records in a single synchronous transactio18n without hitting row limits or causing significant CPU time issues. Option D (SOQL for loop) is the worst approach, as it would attempt to load every individual record into memory, hitting the 50,000-row limit almost immediately and likely causing a LimitException or Request Timeout.
Option B (Batch Apex) is unnecessary for a simple count and is much slower because it runs asynchronously.
Option C (SUM) is used for adding up values in numeric fields, not for counting the number of records. For high-volume record counting, SELECT COUNT(Id) FROM Opportunity is the platform-standard approach to provide data to a Lightning component efficiently.

NEW QUESTION # 21
How can the DISTANCE and GEOLOCATION functions be used in SOQL queries? Choose 2 answers

A. To filter results based on distance from a latitude and longitude.\
B. To get the distance results from a latitude and longitude.
C. To order results by distance from a latitude or longitude.
D. To group results in distance ranges from a latitude and longitude

Answer: B,C
