NEW QUESTION # 29
A developer created and tested a Visualforce page in their developer sandbox, but now receives reports that user encounter view state errors when using it in production.
What should the developer ensure to correct these errors?
Answer: B
Explanation:
The view state in Visualforce represents the state of the page - including the components, field values, and controller state. This error usually occurs when the page's view state becomes too large. To resolve this issue:
C . Ensure variables are marked as transient: The transient keyword in Apex can be used to declare instance variables that should not be part of the view state and therefore not be saved. This is especially useful for large data that does not need to be maintained across postbacks.
Marking properties as private (Option B) or ensuring queries do not exceed governor limits (Option A) might be best practices, but they do not directly impact the view state size. Ensuring profiles have access to the Visualforce page (Option D) is a matter of visibility and access, not related to view state errors.

NEW QUESTION # 30
A Salesforce org has more than 50,000 contacts. A new business process requires a calculation that aggregates data from all of these contact records. This calculation needs to run once a day after business hours.
which two steps should a developer take to accomplish this?
Choose 2 answers
A)
B)
C)
D)
Answer: A,B
Explanation:
When dealing with large datasets and the need to perform complex calculations or data aggregation, batch Apex and scheduling are typically used to efficiently process records in batches and to execute the process during off-peak hours.
Option B is correct because using the @future annotation allows you to run methods in the background, but it is not suitable for operations that need to process more than 50,000 records, which is the governor limit for future methods.
Option C is correct because implementing the Schedulable interface allows you to schedule the class to run at specified times, such as after business hours, which is a requirement for this scenario.
Option A is incorrect because Queueable is typically used for chaining jobs and handling asynchronous processing of individual transactions, not for processing large datasets at scheduled times.
Option D is incorrect because the Database.Batchable interface is what's needed for processing large datasets, not Database.Stateful. The Database.Stateful interface is used to maintain state across batch job transactions.

NEW QUESTION # 31
A developer is building a complex commission calculation engine in Apex that is called from an Opportunity trigger. During QA it was reported that the calculations are incorrect.
The developer has representative test data and passing test methods in their developer sandbox.
Which three tools or techniques could the developer use to execute the code and pause it at key lines to visually inspect values of various Apex variables?
Choose 3 answers
Answer: B,C,D
Explanation:
To debug and troubleshoot the commission calculation engine, a developer can use several tools provided by Salesforce to inspect and pause the execution of Apex code.
Apex Interactive Debugger: It allows real-time debugging of Apex code execution. With this tool, a developer can set breakpoints, step through code, inspect variables, and evaluate expressions.
Developer Console: Although the Developer Console does not allow interactive debugging, it does provide the ability to view logs that capture the execution of code. Debug logs can be inspected to understand the flow of execution and values of variables at different points in time.
Apex Replay Debugger: This tool is part of Salesforce Extensions for Visual Studio Code. It allows a developer to replay a debug log as if they are stepping through the code line by line, which can be very useful to inspect the state of variables at specific points in the execution.

NEW QUESTION # 32
In an organization that has multi-currency enabled, a developer Is tasked with building a Lighting component that displays the top ten Opportunities most recently accessed by the logged in user. The developer must ensure the Amount and LastModifiedDate field values are displayed according to the user's locale.
What is the most effective approach to ensure values displayed respect the user's locale settings?
Answer: A
Explanation:
In a multi-currency Salesforce organization, displaying currency amounts according to the user's locale is crucial for ensuring data clarity and relevance. To achieve this, developers can leverage Salesforce's built-in capabilities to format field values directly within SOQL queries. The FORMAT() function is particularly useful as it formats currency fields according to the organization's locale settings. By using this function in a SOQL query, developers can ensure that the Amount and LastModifiedDate fields are displayed correctly. This method is more effective and efficient than post-processing the values in Apex, which would be required if using wrapper classes or REGEX expressions. Additionally, using the FOR VIEW clause in a SOQL query will mark records as recently viewed, which does not format the fields as per the user's locale.

NEW QUESTION # 33
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
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.
