NEW QUESTION # 66
A developer is debugging an Apex-based order creation process that has a requirement to have three savepoints, SP1, SP2, and 5P3 {created in order), before the final execution of the process.
During the final execution process, the developer has a routine to roll back to SP1 for a given condition. Once the condition is fixed, the code then calls 2 roll back to SP3 to continue with final execution. However, when the roll back to SP3 is called, a Funtime error occurs.
Why does the developer receive a runtime error?
Answer: A
Explanation:
Savepoints in Apex are markers within a transaction and rolling back to an earlier savepoint (SP1) invalidates any savepoints created after it. Thus, SP3 is invalidated when the code rolls back to SP1, causing a runtime error when a rollback to SP3 is attempted.
NEW QUESTION # 67
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?
Answer: B
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 # 68

NEW QUESTION # 69
A developer is tasked with creating a Lightning web component that allows users to create a Case for a selected product, directly from a custom Lightning page. The input fields in the component are displayed in a non-linear fashion on top of an image of the product to help the user better understand the meaning of the fields.
Which two components should a developer use to implement the creation of the Case from the Lightning web component?
Choose 2 answers
Answer: A,C
Explanation:
To implement a Lightning web component that allows users to create a Case, you would need components that allow for input fields and the creation of records.
Option C (Lightning-input) is correct because it allows developers to create custom form input elements that can be positioned in a non-linear fashion as required.
Option D (lightning-record-form) is correct because it provides a simple way to create forms for viewing and editing Salesforce records and would be suitable for creating a new Case record.
Option A (Lightning-record-edit-form) is not a valid component; it seems to be a misprint of lightning-record-edit-form, which is indeed a component used for creating and editing records but was not listed as an option.
Option B (lightning-input-field) is used within the lightning-record-edit-form or lightning-record-view-form components to create editable or displayable fields respectively, but is not as versatile as lightning-input for custom layout purposes.
