NEW QUESTION # 47
A company has reference data stored in multiple custom metadata records that represent default information and delete behavior for certain geographic regions.
When a contact is inserted, the default information should be set on the contact from the custom metadata records based on the contact's address information.
Additionally, if a user attempts to delete a contact that belongs to a flagged region, the user must get an error message.
Depending on company personnel resources, what are two ways to automate this?
Choose 2 answers
- A. Apex trigger
- B. Flow Builder
- C. Remote action
- D. Apex invocable method
Answer: A,B
Explanation:
To automate the process based on the contact's address information and prevent deletion from flagged regions:
Flow Builder: Can be used to set default information on records when they are created.
Apex Trigger: Allows for complex logic to be executed before or after data manipulation operations, including insert and delete. It can be used to enforce rules such as preventing deletion.

NEW QUESTION # 49
A developer created 2 class that implements the Queueable Interface, as follows:
As part of the deployment process, the developer is asked to create a corresponding test class.
Which two actions should the developer take to successfully execute the test class?
Choose 2 answers
- A. Enclose System.enqueueJob(new OrderQueueableJob ()] within Tess. and Test .stopTest (1.
- B. Implement seeAllData=True to ensure the Queueable job is able to run in bulk mode.
- C. Implement Test. isRunningTest() to prevent chaining jobs during test execution.
- D. Ensure the running user of the test class has, at I the View All permission on the Order object.
Answer: A,C
Explanation:
When writing a test class for a Queueable class in Salesforce, the goal is to ensure that the asynchronous code is executed within the test context and that it does not affect the state of the production org or depend on its data.
Option C is correct because using Test.startTest() and Test.stopTest() ensures that the asynchronous code is executed immediately within the test's context. This is essential for testing Queueable classes because it allows the test to wait for the asynchronous process to complete before assertions are made.
Without this, the asynchronous job would not necessarily run during the test execution.
Option D is correct because Test.isRunningTest() can be used within the Queueable class to prevent the chaining of jobs during test execution. Chaining queueable jobs can lead to governor limits being hit and is generally not allowed in test methods. This conditional check allows the developer to bypass sections of the code not suitable for a testing context.
Option A is incorrect because the seeAllData=True annotation is not required for testing Queueable classes, and it is not a best practice to depend on live data for tests. It's preferable to create test data within the test class itself.
Option B is incorrect because having the 'View All' permission on the Order object is not related to the successful execution of the Queueable class in tests. Permissions are typically not enforced in test contexts unless using System.runAs() to test with a specific user context.

NEW QUESTION # 55
A developer wants to write a generic Apex method that will compare the Salesforce Name field between any two object records. For example, to compare the Name field of an Account and an Opportunity; or the Name of an Account and a Contact.
Assuming the Name field exists, how should the developer do this?
- A. Cast each object into an sObject and use sObject.get to compare the Name fields,
- B. Use a string. Replace () method to parse the contents of each Name field and then compare the results.
- C. describe) function to compare the values of each Name field.
- D. Use the Salesforce Metadata API to extract the value of each object and compare the Name fields.
Answer: A
Explanation:
The best way to write a generic Apex method that will compare the Salesforce Name field between any two object records is to cast each object into an sObject and use sObject.get to compare the Name fields. An sObject is a generic abstract type that can represent any object record, and it has methods to access and manipulate the fields of the record. The developer can use the sObject.get method to get the value of a field by passing the field name as a string parameter. The developer can then compare the values of the Name fields of the two sObject records using the == operator. Using the describe function to compare the values of each Name field will not work, as the describe function is used to get the metadata information about an object or a field, such as the label, the data type, or the picklist values, but it does not get the actual value of the field. Using the Salesforce Metadata API to extract the value of each object and compare the Name fields will not work, as the Salesforce Metadata API is used to retrieve and deploy the configuration and customization metadata of the org, such as the objects, fields, layouts, or workflows, but it does not retrieve or deploy the data records of the objects. Using a string.replace method to parse the contents of each Name field and then compare the results will not work, as the string.replace method is used to replace a substring within a string with another substring, but it does not extract the value of the field from the object record.

NEW QUESTION # 63
Which statement is considered a best practice for writing bulk safe Apex triggers?
- A. Add LIMIT 50000 to every SOQL statement.
- B. Perform all DML operations from within a future method.
- C. Add records to collections and perform DML operations against these collections.
- D. Use the Database methods with allorNone set to £21s= instead of DML statements.
