                                      Salesforce Certified Platform Developer II - Multiple Choice Sample Questions (Q177-Q182):

                                      NEW QUESTION # 177
                                      Users report that a button on a custom Lightning web component (LWC) is not saving the data they enter. The button looks to be clicked, but the LWC simply sits there, seemingly doing nothing.
                                      What should the developer use to ensure error messages are properly displayed?

                                      Answer: A

                                      Explanation:
                                      To ensure error messages are properly displayed in a Lightning web component, the developer should use JavaScript to handle errors in the component's client-side code and use HTML to display the message on the UI. This can be combined with Apex exception handling for server-side operations.


                                      NEW QUESTION # 178
                                      Which interface needs to be implemented by an Aura component so that it may be displayed in modal dialog by clicking a button on a Lightning record page?

                                      Answer: B

                                      Explanation:
                                      To display an Aura component in a modal dialog, the component must implement the force:lightningQuickAction or force:lightningQuickActionWithoutHeader interface. This allows it to be used as a quick action on record pages.


                                      NEW QUESTION # 179
                                      Part of a custom Lightning component displays the total number of Opportunities in the org, which are in the millions. The Lightning component uses an Apex method to get the data it needs.
                                      What is the optimal way for a developer to get the total number of Opportunities for the Lightning component?

                                      Answer: B


                                      NEW QUESTION # 180
                                      A developer is writing a Jest test for a Lightning web component that conditionally displays child components based on a user's checkbox selections.
                                      What should the developer do to properly test that the correct components display and hide for each scenario?

                                      Answer: C

                                      Explanation:
                                      To ensure that the DOM is clean before each test runs, the developer should use the afterEach() method to reset it. This is part of the setup and teardown process in Jest tests, which helps to avoid state leakage between tests. Reference:
                                      Jest Globals afterEach


                                      NEW QUESTION # 181
                                      A company has an Apex process that makes multiple extensive database operations and web service callouts. The database processes and web services can take a long time to run and must be run sequentially.
                                      How should the developer write this Apex code without running into governor limits and system limitations?

                                      Answer: B

                                      Explanation:
                                      Queueable Apex is suitable for complex processes that require chaining jobs to run sequentially. It can handle long-running processes without hitting governor limits, as each chained job runs in a new transaction with its own set of governor limits.


                                      NEW QUESTION # 182
                                      ......
