NEW QUESTION # 10
A developer is tasked with ensuring that email addresses entered into the system for Contacts and for a custom object called survey Response c do not belong to a list of blocked domains.
The list of blocked domains is stored in a custom object for ease of maintenance by users. The survey Response c object is populated via a custom Visualforce page.
What is the optimal way to implement this?
- A. Implement the logic in a helper class that is called by an Apex trigger on Contact and from the custom Visualforce page controller.
- B. Implement the logic in an Apex trigger on Contact and also implement the logic within the custom Visualforce page controller.
- C. Implement the logic in validation rules on the Contact and the Burvey Response_c Objects.
- D. Implement the logic in the custom Visualforce page controller and call "that method from an Apex trigger on Contact.
Answer: A
NEW QUESTION # 11
Universal Containers (UC) has enabled the translation workbench and has translated picklist values. UC has a custom multi-select picklist field, Product__c, on the Account object that allows sales reps to specify which of UC's products an Account already has. A developer is tasked with writing an Apex method that retrieves Account records, including the Product_c field.
What should the developer do to ensure the value of Products__c is in the current user's language?
- A. Set the locale on each record in the SOQL result list.
- B. Use tolabel ducts__c) in the fields list of the SOQL query.
- C. Call the translate method on each record in the SOQL result list.
- D. Use the Locale clause in the SOQL query.
Answer: B
Explanation:
To ensure the value of Products__c is in the current user's language, the developer should use toLabel(Products__c) in the fields list of the SOQL query. The toLabel() function converts the picklist values in the query result to the user's language, if the translation workbench is enabled and the values are translated. This way, the developer can display the translated values of the custom multi-select picklist field in the Apex method. Setting the locale on each record in the SOQL result list would not work, as the locale is a user attribute, not a record attribute, and it cannot be changed by Apex code. Calling the translate method on each record in the SOQL result list would not work, as there is no such method in Apex. Using the Locale clause in the SOQL query would not work, as there is no such clause in SOQL. Reference: [Using the toLabel() Function], [Locale Class]

NEW QUESTION # 21
A developer has a test class that creates test data before making a mock callout but now receives a 'You have uncommitted work pending. Please commit or rollback before calling out' error.
Which step should be taken to resolve the error?
- A. Ensure the records are inserted before the Test.startTess() statement and the mock callout occurs after the Test. Startest().
- B. Ensure both the Insertion and mock callout occur after the I==L. stoptest_().
- C. Ensure the records are Inserted before the Tezt.startTest() statement and the mock callout occurs within a method annotated with @testSetup.
- D. Ensure both the insertion and mock callout occur after the Test.startTest().
Answer: A
Explanation:
When working with Apex tests that involve callouts, it's important to avoid the 'uncommitted work pending' error. This error typically occurs because DML operations (like inserts) are pending when a callout is attempted. Salesforce requires that all callouts are made before any DML operations in a transaction. To avoid this, the pattern is to insert the records before calling Test.startTest(), and then make the callout after this call. Test.startTest() marks the point where your actual test begins, and it resets the governor limits. By making the callout after this point, it ensures that the DML operations are committed and you are within a new execution context regarding governor limits.

NEW QUESTION # 23
A company uses Dpportunities to track sales to their customers and their org has millions of Opportunities.
They want to begin to track revenue over time through a related Revenue object.
As part of their initial implementation, they want to perform a one-time seeding of their data by automatically creating and populating Revenue records for Opportunities, based on complex logic.
They estimate that roughly 100,000 Opportunities will have Revenue records created and populated.
What is the optimal way to automate this?
- A. Use system, enqueuJob (| to invoke a gueusable class.
- B. Use Database. executeBatch () to invoke a Queueable class.
- C. Use system, acheduladeb() to schedule a patakape.Scheduleable class.
- D. Use Database. =executeBatch() to invoke a Database. Batchable class.
Answer: D
Explanation:
For a one-time bulk operation on a large data set, using a Database.Batchable class is the best approach. This allows complex logic to be processed in manageable chunks and efficiently manages system resources.

NEW QUESTION # 25
An Apex trigger creates a Contract record every time an Opportunity record is marked as Closed and Won.
This trigger is working great, except (due to a recent acquisition) Opportunity records need to be loaded into the Salesforce instance.
When a test batch of records are loaded, the Apex trigger creates Contract records. A developer is tasked with preventing Contract records from being created when mass Loading the Opportunities, but the daily users still need to have the Contract records created.
What is the most extendable way to update the Apex trigger to accomplish this?
- A. Use a list custom setting to disable the trigger for the user who loads the data.
- B. Use a hierarchy custom setting to skip executing the logic inside the trigger for the user who loads the data.
- C. Add a validation rule to the Contract to prevent Contract creation by the user who loads the data.
- D. Add the Profile ID of the user who loads the data to the trigger, so the trigger will not fire for this user.
Answer: B

2.0 is managed through Named Credentials.References: Named Credentials as Callout Endpoints
NEW QUESTION # 27
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. Query the Account Object upon each call to insert invoice data to fetch the Salesforce ID corresponding to the Customer Number on the invoice.
- B. Ensure Customer Number cis an External ID and that a custom field Invoice Number cis an External ID and Upsert invoice data nightly.
- C. Use Salesforce Connect and external data objects to seamlessly import the invoice data into Salesforce without custom code.
- D. Create a cross-reference table in the custom invoicing system with the Salesforce Account ID of each Customer and insert invoice data nightly,
Answer: D
NEW QUESTION # 28
When the code is executed, the callout is unsuccessful and the following error appears within the Developer Console:
System.CalloutException: Unauthorized endpoint
Which recommended approach should the developer implement
to resolve the callout exception?
- A. Use the SetHeader() method to specify Basic Authentication,
- B. Change the access modifier for ERPCatalog from public to global.
- C. Annotate the getkRFCatalogContents method with @Future (Callout-true),
- D. Create a remote site setting configuration that includes the endpoint.
Answer: D
Explanation:
The System.CalloutException with the message "Unauthorized endpoint" typically indicates that the endpoint to which the callout is being made has not been authorized in the Salesforce org's security settings. To resolve this, the developer must navigate to the Remote Site Settings in the Salesforce Setup and add the endpoint URL as a new remote site. This step is necessary to authorize the Salesforce org to send outbound callouts to that specific endpoint. Annotating with @Future(Callout=true) is necessary for making callouts from methods that perform DML operations, but it does not resolve endpoint authorization issues. Similarly, changing the access modifier or using SetHeader() for authentication would not address the unauthorized endpoint error.
