NEW QUESTION # 104
A developer created a custom order management app that uses an Apex class. The order is represented by an Order object and an Orderltem object that has a master-detail relationship to Order. During order processing, an order may be split into multiple orders.
What should a developer do to allow their code to move some existing Orderltem records to a new Order record?
Answer: D
Explanation:
The developer should select the Allow reparenting option on the master-detail relationship between Order and OrderItem. This option enables the developer to change the parent record of a child record in a master-detail relationship, which is also known as reparenting. By default, reparenting is not allowed in master-detail relationships, because the child record inherits the sharing and security settings of its parent record. However, in some cases, such as splitting an order into multiple orders, reparenting may be necessary to move some existing OrderItem records to a new Order record. The developer can use the Apex Data Manipulation Language (DML) statements, such as update or upsert, to change the parent record of the OrderItem records.
Changing the master-detail relationship to an external lookup relationship is not a valid option, because external lookup relationships are only available for external objects, which are objects that map to data stored outside Salesforce. Adding without sharing to the Apex class declaration is not a relevant option, because it only affects the sharing rules that apply to the Apex class, not the relationship between the objects. Creating a junction object between OrderItem and Order is not a suitable option, because it would create a many-to-many relationship between the objects, which is not the desired outcome.

NEW QUESTION # 105
A developer creates a batch Apex job to update a large number of records, and receives reports of the job timing out and not completing.
What is the first step towards troubleshooting the issue?
Answer: A
Explanation:
When a batch Apex job is timing out and not completing, the first step in troubleshooting is to check the job's status and logs in the Asynchronous Job Monitoring page. This page provides information about all asynchronous Apex jobs, including batch Apex, scheduled Apex, future methods, and queueable Apex.
Option D: Check the asynchronous job monitoring page to view the job status and logs.
Correct Approach.
The Asynchronous Job Monitoring page (also known as the Apex Jobs page) in Salesforce Setup allows developers to see the status of all asynchronous Apex jobs.
By checking this page, the developer can see whether the batch job is still running, failed, or completed.
If the job has failed, the page provides error messages that can help identify the cause of the failure.
This is the first step to determine what is happening with the batch job.
While checking the debug logs can provide detailed information, it is more efficient to first check the job status on the asynchronous job monitoring page.
Debug logs can be large and may not be generated if the job did not execute properly.
After identifying the job's status and any error messages, the developer can then decide if checking debug logs is necessary.
Option C: Decrease the batch size to reduce the load on the system.
Possible Solution, Not First Step.
Decreasing the batch size may help prevent timeouts by processing fewer records at a time.
However, before making changes to the batch job, the developer should first investigate the cause of the timeout.
Option A: Disable the batch job and recreate it with a smaller number of records.
Not Recommended as First Step.
Disabling and recreating the batch job without understanding the issue may not resolve the problem.
It's important to diagnose the issue before making changes.
Conclusion:
The first step towards troubleshooting a batch Apex job that is timing out is to check the asynchronous job monitoring page to view the job's status and any error messages.
This provides immediate insight into what is happening with the job and guides the next steps in troubleshooting.

Option B: Check the debug logs for the batch job.
Next Step, Not First Step.

NEW QUESTION # 107
In terms of the MVC paradigm, what are two advantages of implementing the view layer of a Salesforce application using Lightning Web Component-based development over Visualforce?
Choose 2 answers
Answer: A,B
Explanation:
The correct answers are option C and option D. Lightning Web Components are self-contained and reusable units of an application that follow web standards and can leverage modern web features. They also benefit from a rich component ecosystem that includes standard components, custom components, and third-party components. Visualforce, on the other hand, is a legacy framework that relies on server-side rendering and proprietary markup. It does not offer the same level of modularity, performance, and interoperability as Lightning Web Components. References: The information can be referenced from the official Salesforce documentation and learning materials available on Trailhead. Specifically, it aligns with the objectives outlined in Lightning Web Components Basics, where the benefits and features of Lightning Web Components are discussed. Lightning Web Components Basics

Answer: B,D,E
Explanation:
A developer can execute tests in an org using the following methods:
* Setup Menu: By browsing to setup->Apex Test Execution, the developer can select and run tests from the user interface1.
* SalesforceDX: By using the Salesforce CLI on the command line, the developer can run tests in an org using the force:apex:test:run command2. This command can also be used from Salesforce Extensions for VS Code or from within third-party continuous integration tools, such as Jenkins or CircleCI2.
* Tooling API: The developer can also run tests using the Tooling REST API. Use the /runTestsAsynchronous/ and /runTestsSynchronous/ endpoints to run tests asynchronously or synchronously3.
