                                      NEW QUESTION # 87
                                      A developer is responsible for formulating the deployment process for a Salesforce project. The project follows a source-driven development approach, and the developer wants to ensure efficient deployment and version control of the metadata changes.
                                      Which tool or mechanism should be utilized for managing the source-driven deployment process?

                                      Answer: A

                                      Explanation:
                                      Salesforce CLI with Salesforce DX is the best tool for managing a source-driven deployment process. It facilitates version control, scriptable deployment, and rollback, and is optimized for collaboration and continuous integration.


                                      NEW QUESTION # 88
                                      A Salesforce developer is hired by a multi-national company to build a custom Lightning application that shows employees their employment benefits and earned commissions over time. The application must acknowledge and respect the user's locale context for dates, times, numbers, currency, and currency symbols.
                                      When using Aura components, which approach should the developer implement to ensure the Lightning application complies with the user's locale?

                                      Answer: C

                                      Explanation:
                                      The $Locale value provider should be used to ensure the Lightning application respects the user's locale for dates, times, numbers, currency, and currency symbols. This global value provider gives components access to locale formats and labels, which are automatically rendered according to the user's locale settings.


                                      NEW QUESTION # 89
                                      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) historical 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?

                                      Answer: A

                                      Explanation:
                                      A hierarchy custom setting can be used to create a configuration that the trigger checks before executing its logic. This allows admins to set the configuration to bypass the trigger logic when loading data, without changing the trigger itself or impacting other users.


                                      NEW QUESTION # 90
                                      Refer to the code snippet below:

                                      A custom object called Credit_Memo__c exists in a Salesforce environment. As part of a new feature development that retrieves and manipulates this type of record, the developer needs to ensure race conditions are prevented when a set of records are modified within an Apex transaction. In the preceding Apex code, how can the developer alter the query statement to use SOQL features to prevent race conditions within a transaction? A)

                                      B)

                                      C)

                                      D)

                                      Answer: D

                                      Explanation:
                                      To prevent race conditions during an Apex transaction, the SOQL query can be modified to include the "FOR UPDATE" keyword. This keyword locks the records that are returned by the query, preventing other transactions from modifying them until the current transaction is complete. This ensures that the retrieved records cannot be changed by another process before the current transaction is completed, thus preventing race conditions. The correct option to use in the code snippet provided is:
                                      [SELECT Id, Name, Amount__c FROM Credit_Memo__c WHERE Customer_Id__c = :customerId LIMIT 50 FOR UPDATE] This will lock up to 50 records of Credit_Memo__c with the specified Customer_Id__c for the duration of the transaction.
                                      FOR UPDATE
                                      Preventing Record Update Conflicts


                                      NEW QUESTION # 91
                                      A developer used custom settings to store some configuration data that changes occasionally. However, tests are now Failing in some of the sandboxes that were recently refreshed.
                                      What should be done to eliminate this issue going forward?

                                      Answer: C

                                      Explanation:
                                      Replacing custom settings with custom metadata types is a good solution to ensure that test data is consistent across environments. Custom metadata types are deployable, and their records are available in test methods by default, unlike List Custom Settings which need to be manually recreated in each environment after a refresh.
