NEW QUESTION # 178
A developer is working with existing functionality that tracks how many times a stage has changed for an Opportunity. When the Opportunity's stage is changed, a workflow rule is fired to increase the value of a field by one. The developer wrote an after trigger to create a child record when the field changes from 4 to 5.
A user changes the stage of an Opportunity and manually sets the count field to 4. The count field updates to 5, but the child record is not created.
What is the reason this is happening?
Answer: C

NEW QUESTION # 179
A developer is asked to develop a new AppFxchange application. A feature of the program creates Survey records when a Case reaches a certain stage and is of a certain Record Type. This feature needs to be configurable, as different Salesforce instances require Surveys at different times. Additionally, the out-of-the-box AppExchange app needs to come with a set of best practice settings that apply to most customers.
What should the developer use to store and package the custom configuration settings for the app?
Answer: A
Explanation:
Custom metadata is best for storing configurable settings. It's deployable, packageable, and upgradeable. Allows different configurations for different instances.
NEW QUESTION # 180
A company has a custom component that allows users to search for records of a certain object type by invoking an Apex Controller that returns a list of results based on the user's input. When the search is completed, a searchComplete event is fired, with the results put in a results attribute of the event. The component is designed to be used within other components and may appear on a single page more than once.
What is the optimal code that should be added to fire the event when the search has completed?
A)
B)
C)
D)
Answer: A
Explanation:
The correct code to fire the event when the search has completed in a Lightning component is option B. $A.get("e.c.searchComplete") is the syntax used to get the event, setParams is used to set the parameters, and fire is used to dispatch the event.
NEW QUESTION # 181
A business requires that every parent record must have a child record. A developer writes an Apex method with two DML statements to insert a parent record and a child record.
A validation rule blocks child records from being created. The method uses a try/catch block to handle the DML exception.
What should the developer do to ensure the parent always has a child record?
Answer: C
Explanation:
By setting a savepoint before the DML operations and rolling back to that savepoint in the event of an exception, the developer can ensure that the parent record is not committed without a corresponding child record.

NEW QUESTION # 182
A company needs to automatically delete sensitive information after seven years.
This could delete almost a million records every day.
How can this be achieved?
Answer: A
Explanation:
Batch Apex is designed to handle large data operations by breaking the transaction into smaller batches. Scheduling a batch process to run daily enables the system to manage the deletion of large numbers of records efficiently, without hitting governor limits. It's the best practice for performing mass deletions on a regular schedule.
