NEW QUESTION # 182
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: B,D
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 # 183
Refer to the component code and requirements below:
Requirements: 1. For mobile devices, the information should display in three rows. 2. For desktops and tablets, the information should display in a single row. Requirement 2 Is not displaying as desired. Which option has the correct component code to meet the requirements for desktops and tablets? A)
B)
C)
D)
Answer: C
Explanation:
To meet the requirements specified for displaying information differently on mobile devices versus desktops and tablets, the developer needs to use Lightning Layout and Lightning Layout Item components with appropriate size attributes to control the layout based on the form factor.
Option A is correct because it sets the size attribute to "12" for desktop and tablet devices, which tells the framework to take the full width of the container, resulting in a single row. For mobile devices, it defaults to full width, which will stack the layout items vertically, resulting in three rows.
Options B, C, and D are incorrect because they either do not set the correct size attributes for desktops and tablets or do not maintain the proper structure that would result in a single row for these devices.

NEW QUESTION # 184
Consider the above trigger intended to assign the Account to the manager of the Account's region, Which two changes should a developer make in this trigger to adhere to best practices?
Answer: A,D
Explanation:
Moving the SOQL query outside the loop prevents it from being executed multiple times, which can lead to hitting governor limits. The last line updating the accountList is indeed needed to save the changes made to the Account records, so removing it is not recommended. Instead, the query should be moved outside the loop and records should be collected in a map for efficiency, which is not one of the provided options. Reference:
