NEW QUESTION # 123
The orderHelper class is a utility class that contains business logic for processing orders. Consider the following code snippet:
A developer needs to create a constant named delivery_multiplier with a value of 4.15. The value of the constant should not change at any time in the code.
How should the developer declare the delivery multiplier constant to meet the business objectives?

• A. constant decimal DELIVERY_MULTIPLIER = 4.15;
• B. decimal DELIVERY_MULTIPLIER = 4.15;
• C. static decimal DELIVERY_MULTIPLIER = 4.15;
• D. static final decimal DELIVERY_MULTIPLIER = 4.15;

Answer: D

Explanation:
Declaring the constant asstaticensures it is shared across all instances of the class.
Declaring it asfinalensures its value cannot be modified after initialization.

NEW QUESTION # 129
A developer wants to improve runtime performance of Apex calls by caching results on the client.
What is the most efficient way to implement this and follow best practices?

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

Answer: B

Explanation:
To improve runtime performance by caching Apex call results on the client, the developer should decorate the server-side method with @AuraEnabled(cacheable=true).
@AuraEnabled(cacheable=true) Annotation:
When applied to an Apex method, it enables the method's results to be cached on the client, improving performance for subsequent calls.
This is especially effective in Lightning Web Components (LWC) and can also be used in Aura components.
"To cache method results, annotate the method with @AuraEnabled(cacheable=true). Methods annotated with cacheable=true are called cached methods."
- Lightning Web Components Developer Guide: Call Apex Methods
Why Not Other Options:
A . Call the setStorable() method on the action in the JavaScript client-side code: This approach is used in Aura components but is less efficient and not considered best practice compared to using cacheable=true.
"For improved performance, use @AuraEnabled(cacheable=true) instead of action.setStorable()."
- Aura Components Developer Guide: Calling Server-Side Actions
B . Set a cookie in the browser for use upon return to the page: Managing cookies for caching Apex results is not efficient and can lead to security and scalability issues.
C . Decorate the server-side method with @AuraEnabled(storable=true): There is no storable=true parameter for @AuraEnabled. The correct parameter is cacheable=true.
Best Practices:
Use @AuraEnabled(cacheable=true): This is the recommended way to cache Apex method results in Lightning components.
"Apex methods annotated with @AuraEnabled(cacheable=true) are cached on the client and shared across components."
- Lightning Web Components Developer Guide: Apex Methods Cache
Conclusion: By decorating the Apex method with @AuraEnabled(cacheable=true), the developer enables client-side caching of the method's results, improving runtime performance in an efficient and recommended way.

NEW QUESTION # 130

NEW QUESTION # 131
Which two actions may cause triggers to fire?
Choose 2 answers

• A. Updates to FeedItem
• B. Changing a user's default division when the transfer division option is checked
• C. Cascading delete operations
• D. Renaming or replacing a picklist entry

Answer: A,C

Explanation:
In Salesforce, triggers are executed in response to specific database events on standard objects (such as Account or Contact) and custom objects. The following actions can cause triggers to fire:
Option A: Cascading delete operations
Reference:
"Deleting a parent record in a master-detail relationship deletes all the detail records. This deletion can fire any triggers on those detail records."
- Salesforce Developer Guide: Triggers and Order of Execution
Option C: Updates to FeedItem
"You can write triggers for certain standard objects, including FeedItem."
- Salesforce Developer Guide: Triggers
Why Other Options Are Incorrect:
Option B: Changing a user's default division does not fire triggers because it does not perform DML operations on records that would invoke triggers.
Option D: Renaming or replacing a picklist entry changes metadata and does not perform DML operations on records, so triggers are not fired.

NEW QUESTION # 132

NEW QUESTION # 135
A Primaryid__c custom field exists on the candidate_ c custom object. The field is used to store each candidate's id number and is marked as Unique in the schema definition.
As part of a data enrichment process, Universal Containers has a CSV file that contains updated data for all candidates in the system. The file contains each Candidate's primary id as a data point. Universal Containers wants to upload this information into Salesforce, while ensuring all data rows are correctly mapped to a candidate in the system.
Which technique should the developer implement to streamline the data upload?

• A. Create a before Insert trigger to correctly map the records.
• B. Create a before save flow to correctly map the records.
• C. Upload the CSV into a custom object related to Candidate__ c.
• D. Update the PrimaryId__ c field definition to mark it as an External Id.

Answer: D

Explanation:
Option C: Update the PrimaryId__c field definition to mark it as an External Id.
Correct Answer.
Marking PrimaryId__c as an External ID allows data loading tools to match records based on this field.
This facilitates upserting data and ensures that the CSV data correctly maps to existing records.
A trigger is unnecessary when External IDs can be used for mapping.
Option B: Create a before save flow to correctly map the records.
Incorrect.
A flow adds unnecessary complexity; External IDs suffice.
Option D: Upload the CSV into a custom object related to Candidate__c.
Unnecessary.
This does not streamline the process and complicates data management.
Conclusion:
The developer should update the PrimaryId__c field to mark it as an External ID, which is Option C.
Reference:
Upserting Records with External IDs
Option A: Create a before Insert trigger to correctly map the records.
Incorrect.

NEW QUESTION # 136
Which code statement includes an Apex method named updateaccounts in the Class AccountCont rolles for use in a Lightning web component?

• A.
• B.
• C.
• D.

Answer: D

Explanation:
The correct option is C, which includes the import statement for an Apex method named updateAccounts in the class AccountController. In Salesforce, to use an Apex method in a Lightning Web Component (LWC), you need to import it using a specific syntax. The syntax includes the import keyword followed by the method name from '@salesforce/apex/ClassName.MethodName'. This makes the Apex method available for use within the LWC. References:
