NEW QUESTION # 54
A company manages information about their product offerings in custom objects named Catalog and Catalog Item. Catalog Item has a master-detail field to Catalog, and each Catalog may have as many as 100,000 Catalog Items. Both custom objects have a CurrencyIsoCode text field that contains the currency code they should use. If a Catalog's CurrencyIsoCode changes, all of its Catalog Items' CurrencyIsoCodes should be changed as well. What should a developer use to update the CurrencyIsoCodes on the Catalog Items when the Catalog's CurrencyIsoCode changes?
- A. A Database.Schedulable and Database.Batchable class that queries the Catalog Item object and updates the Catalog Items if the Catalog CurrencyIsoCode is different.
- B. A Database.Schedulable and Database.Batchable class that queries the Catalog object and updates the Catalog Items if the Catalog CurrencyIsoCode is different.
- C. An after insert trigger on Catalog Item that updates the Catalog Items if the Catalog's CurrencyIsoCode is different.
- D. An after update trigger on Catalog that updates the Catalog Items if the Catalog's CurrencyIsoCode is different.
Answer: A
Explanation:
The primary challenge in this scenario is the high volume of child records (up to 100,000 Catalog Items) associated with a single parent Catalog. In Salesforce, synchronous transactions like Apex triggers are subject to strict governor limits, most notably the limit of 10,000 DML rows per transaction. If a developer were to use an "after update" trigger on the Catalog object (Option A) to update 100,000 child items, the transaction would immediately fail with a LimitException as soon as it exceeded that threshold.23 To handle such a massive update succ4essfully, the developer must use an asynchronous approach, specifically Batch Apex. By implementing Database.Batchable, the platf5orm can process the 100,000 records in smaller chunks (batches), each within its own set of governor limits. Option D is the correct implementation because the Batch class should query the Catalog Item (the child object) where the CurrencyIsoCode does not match the parent Catalog. This targets only the records that need modification.
While Option C suggests batching the parent Catalog, it is more efficient to query the child items directly to ensure every record needing an update is processed across the multiple batches of the execution. This ensures data consistency across the entire 100,000 record set without risking transaction failures.

NEW QUESTION # 59
A developer needs to store variables to control the style and behavior of a Lightning Web Component.
Which feature can be used to ensure that the variables are testable in both Production and all Sandboxes?
- A. Custom setting
- B. Custom variable
- C. Custom metadata
- D. Custom object
Answer: C
Explanation:
The feature that can be used to store variables to control the style and behavior of a Lightning Web Component and ensure that the variables are testable in both Production and all Sandboxes is custom metadata. Custom metadata is data that describes other data and can be used to define the structure for application metadata. Custom metadata can be accessed in Apex, SOQL, validation rules, formulas, and flows. Custom metadata can also be deployed, packaged, and upgraded like other metadata. Custom setting is a type of custom object that can store data that applies to a specific organization, profile, or user. Custom setting data is cached and can be accessed in Apex, SOQL, validation rules, formulas, and flows. However, custom setting data is not included in change sets or packages and must be manually migrated to other environments. Custom object is a type of object that can store data that is specific to an organization or application. Custom object data can be accessed in Apex, SOQL, validation rules, formulas, and flows. Custom object data can also be deployed, packaged, and upgraded like other metadata. However, custom object data is not cached and may have performance implications when used to control the style and behavior of a Lightning Web Component. Custom variable is not a valid feature in Salesforce. Reference: [Custom Metadata Types], [Custom Settings], [Custom Objects]
NEW QUESTION # 60
A developer wrote a trigger on Opportunity that will update a custom Last Sold Date field on the Opportunity's Account whenever an Opportunity is closed. In the test class for the trigger, the assertion to validate the Last Sold Date field fails.
What might be causing the failed assertion?
- A. The test class has not re-queried the Account record after updating the Opportunity.
- B. The test class has not implemented seealldata=true in the test method.
- C. The test class has not defined an Account owner when inserting the test data.
- D. The test class is not using System. runs () to run tests as a Salesforce administrator.
Answer: A
Explanation:
The test class may not be re-querying the Account record after updating the Opportunity, which is necessary to verify the updated field values. If the test does not query the database to get the most recent data after the trigger runs, it will not see the changes made by the trigger.

Which component should the developer add to the form to display error messages?
- A. apex:messages
- B. lightning-messages
- C. aura:messages
- D. lightning-error
Answer: B
Explanation:
The correct answer is B, lightning-messages. This Lightning Web Components (LWC) service component provides a way to display error messages that are generated during the processing of lightning-input-field components within a lightning-record-edit-form.

NEW QUESTION # 64
Refer to the markup below:
HTML
<template>
<lightning-record-form
record-id={recordId}
object-api-name="Account"
layout-type="Full">
</lightning-record-form>
</template>
A Lightning web component displays the Account name and two custom fields out of 275 that exist on the object. The custom fields are correctly declared and populated. However, the developer receives complain2223ts that the component performs slowly. What can the developer d2425o to improve the performance?
- A. Replace layout-type="Full" with layout-type="Partial".
- B. Replace layout-type="Full" with fields={fields}.
- C. Add density="compact" to the component.
- D. Add cache="true" to the component.
Answer: B
Explanation:
The lightning-record-form is a powerful, high-level component that simplifies data entry and display.
However, its performance is heavily influenced by the layout-type attribute. When layout-type="Full" is used, the component fetches and renders every single field defined on the object's "Full" page layout in the Salesforce metadata. In this case, the Account object has 275 fields. Fetching and rendering such a large volume of metadata and data causes a significant performance lag, even if the user only cares about three specific fields.
To improve performance, the developer should switch from a layout-based approach to a field-based approach. By removing the layout-type attribute and adding the fields attribute (Option A), the developer can pass an array of only the specific field API names required (e.g., ['Name', 'CustomField1__c',
'CustomField2__c']). This drastically reduces the amount of data requested from the Lightning Data Service (LDS) and minimizes the DOM elements the browser needs to render. Option C is incorrect because "Partial" is not a valid value for layout-type; the only supported values are "Full" and "Compact". Option B only affects the visual spacing of the fields and does not reduce the data load. Option A is the direct and most effective way to optimize component responsiveness by limiting the data scope.
NEW QUESTION # 65
In an organization that has multi-currency enabled, a developer is tasked with building a Lighting Component that displays the top ten Opportunities most recently access by the logged in user.

- A. Use the FOR VIEW clause in the SOQL Query.
- B. Use the FORMAT() function in the SOQL query.
- C. Use a wrapper class to format the values retrieved via SOQL.
- D. Use REGEX expressions to format the values retrieved via SOQL.
Answer: B

NEW QUESTION # 67
After a Platform Event is defined in a Salesforce org, events can be published via which two mechanisms?
Choose 2 answers
- A. External Apps require a custom Apex web service.
- B. Internal Apps can use Process Builder.
- C. internal Apps can use Outbound Messages
- D. External Apps can use the standard Streaming API.
Answer: B,D
Explanation:
Explanation
internal apps can use processes, flows, or Apex to publish platform event messages from a Salesforce app.
Process Builder is a tool that lets you automate business processes by creating processes. You can use Process Builder to publish platform event messages when a record changes or when a platform event occurs.
external apps can use Salesforce APIs to publish platform event messages. You can use any Salesforce API to create platform events, such as SOAP API, REST API, or Bulk API. The Streaming API is a Salesforce API that lets you push a stream of notifications from Salesforce to external apps. You can use the Streaming API to publish platform event messages by creating records of your event type.
Therefore, using Process Builder and Streaming API are two mechanisms to publish platform event messages after a platform event is defined in a Salesforce org.

NEW QUESTION # 71
Given the following information regarding Universal Containers (UC):
* UC represents their customers as Accounts in Salesforce.
* All customers have a unique Customer__Number_c that is unique across all of UC's systems.
* UC also has a custom Invoice c object, with a Lookup to Account, to represent invoices that are sent out from their external system.
UC wants to integrate invoice data back into Salesforce so Sales Reps can see when a customer pays their bills on time.
What is the optimal way to implement this?
- A. Ensure Customer Number cis an External ID and that a custom field Invoice Number cis an External ID and Upsert invoice data nightly.
- B. Query the Account Object upon each call to insert invoice data to fetch the Salesforce ID corresponding to the Customer Number on the invoice.
- C. Create a cross-reference table in the custom invoicing system with the Salesforce Account ID of each Customer and insert invoice data nightly,
- D. Use Salesforce Connect and external data objects to seamlessly import the invoice data into Salesforce without custom code.
Answer: A
Explanation:
The optimal way to integrate invoice data into Salesforce, allowing for the upsert operation which can insert or update records based on the presence of the External ID, is to use the External ID fields. This ensures that the invoices are associated correctly with the existing Accounts and that upsert operations can be performed efficiently.
