NEW QUESTION # 128
Universal Containers is implementing a new approval process for expense reimbursements. The process requires complex logic to determine the appropriate approver based on factors such as expense amount, employee role, and project type. The solution should allow for flexibility and future changes in the approval rules.
Which approach would be the most suitable for implementing this logic?
Answer: B
Explanation:
Creating a custom Apex class with methods to determine the appropriate approver is the most suitable approach when dealing with complex logic and the need for flexibility. This approach allows for centralized logic that can be easily maintained and updated as business requirements change.References: Apex Developer Guide - Apex Classes

NEW QUESTION # 130
A developer receives complaints that the component loads slowly.
Which change can the developer implement to make the component perform faster?
Answer: B
Explanation:
To make the component perform faster, the developer should change the default for showContactInfo to false. The showContactInfo attribute is used to control whether the contactInfo component is rendered or not. By default, it is set to true, which means that the contactInfo component is always rendered, even if the user does not need to see it. This can slow down the component loading, as the contactInfo component may have some complex logic or data fetching in its controller or helper. By changing the default for showContactInfo to false, the developer can improve the component performance, as the contactInfo component will only be rendered when the user clicks on the Show Contact Info button, which triggers the toggleContactInfo function and sets the showContactInfo attribute to true. Changing the type of contactInfo to "Map" would not make the component perform faster, as contactInfo is not a variable, but a component name. A Map is a collection type that stores key-value pairs, and it is not related to the component rendering. Moving the contents of <c:contactInfo> into the component would not make the component perform faster, as it would not change the logic or data fetching of the contactInfo component. It would only make the component code less modular and reusable. Adding a change event handler for showContactInfo would not make the component perform faster, as it would not change the rendering of the contactInfo component. It would only add an extra function that is executed whenever the showContactInfo attribute changes, which may not be necessary for the component functionality.
