A company wants to run different logic based on an Opportunity's record type.
Which code segment handles this request and follows best practices?
A)
B)
C)
D)
The use of getRecordTypeInfosByDeveloperName is a best practice to handle record types. This approach avoids the need for SOQL queries, reducing the number of governor limits consumed, and efficiently retrieves record type Ids by their DeveloperName, which is consistent across all Salesforce environments.
An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature.
The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters.
What is the optimal way to implement these requirements?
A single trigger on Contact that handles both after update and before update events, utilizing helper classes for each logic set, is the most optimal implementation. It centralizes the logic for maintaining primary contacts and normalizing last names while allowing for clear separation of concerns through helper classes.
A company uses Salesforce to sell products to customers. They also have an external product information management (PIM) system that is the system of record for products.
A developer received these requirements:
* Whenever a product is created or updated in the PIM, a product must be
created or updated as a Product? record in Salesforce and a PricebookEntry
record must be created or updated automatically by Salesforce.
= The PricebookEntry should be created in a Priceboek2 that is specified in a
custom setting.
What should the developer use to satisfy these requirements?
Custom Apex REST services are the optimal solution for integrating Salesforce with an external PIM system. When a product is created or updated in the PIM, the external system can make a REST call to a custom Apex REST endpoint in Salesforce, which then can create or update the Product2 and PricebookEntry records. This method allows using custom settings to determine the Pricebook2 dynamically.
As part of a custom interface, a developer team creates various new Lightning web components. Each of the components handles errors using toast messages. When the development is complete, all the components are added to the same Lightning page.
During acceptance testing, users complain about the long chain of toast messages that display when errors occur loading the components.
Which two techniques should the developer implement to improve the user experience?
Choose 2 answers
The scenario describes a common issue when multiple components are used on the same Lightning page and each component manages its error handling independently, leading to a 'long chain of toast messages' which can be overwhelming for users.
To improve user experience, the developers can implement the following techniques:
A . Use a Lightning web component to aggregate and display all errors: This method involves creating a centralized component responsible for handling all error messages. This component would receive error notifications from other components and then display them in a user-friendly manner. The benefit of this approach is that it provides a single, consistent interface for error messages, reducing the clutter and confusion that can be caused by multiple toasts.
D . Use public properties on each component to display the error messages: By using public properties, components can expose their error states to a parent or orchestrating component, which can then display these errors in a single, consolidated way. This avoids the issue of multiple toast notifications and allows for a more integrated error handling experience.
The other options presented are less ideal:
B . Using the window.alert() method is not recommended in a professional Salesforce environment as it is considered a disruptive way to show errors and does not align with the Salesforce Lightning design system.
C . Using a <template> tag to display in-place error messages could be a viable option for displaying error messages within the component itself, but it does not address the issue of multiple errors stacking up from different components as described in the scenario.

For implementing public properties: Lightning Web Components Developer Guide - Public Properties
A developer is working on an integration between Salestorce and an external system. The integration requires sending a large amount of data to the external systern, which can cause long response times and timeouts.
To optimize the performance and avoid timeouts, which technique should be used?
Implementing an asynchronous callout using the Continuation class is the optimal solution to handle long response times and avoid timeouts in Salesforce. It allows the Apex code to make a long-running request to an external service and free up the thread to serve other requests.
