                                      Salesforce Certified Platform Developer II - Multiple Choice Sample Questions:

                                      Consider the following code snippet:

                                      The Apex method is executed in an environment with a large data volume count for Accounts, and the query is performing poorly. Which technique should the developer implement to ensure the query performs optimally, while preserving the entire result set?

                                      • A. Use the Database queryLocator method to retrieve the accounts.
                                      • B. Break down the query into two individual queries and join the two result sets.
                                      • C. Create a formula field to combine the createdDate and RecordType value, then filter based on the formula.
                                      • D. Annotate the method with the @Future annotation

                                      A developer is building a Lightning web component that searches
                                      for Contacts. The component must communicate the search
                                      results to other unrelated Lightning web components, that are in
                                      different DOM trees, when the search completes.
                                      What should the developer do to implement the communication?

                                      • A. Fire a custom component event.
                                      • B. Fire an application event.
                                      • C. Publish a message on a message channel.
                                      • D. Publish an event on an event channel.

                                      Exhibit:

                                      The test method above tests in Apex trigger that the developer knows will make a lot of queries when a lot of Accounts are simultaneously updated to be customers. The test method fails at the Line 20 because of too many SOQL queries. What is the correct way to fix this?

                                      • A. Replace most of the Apex Trigger with Process Builder processes to reduce the number of queries in the trigger
                                      • B. Add Test.startTest() before Line 18 of the code and add Test.stopTest() after line 18 of the code
                                      • C. Add Test.startTest() before and Test.stopTest() after both Line 7 of the code and Line 20 of the code
                                      • D. Change the DataFactory class to create fewer Accounts so that the number of queries in the trigger is reduced

                                      How should a developer assert that a trigger with an asynchronous process has successfully run?

                                      • A. Insert records into Salesforce, use seeAllData=true, then perform assertions.
                                      • B. Create all test data in the test class, invoke Test.startTest{} and Test.etopTaat {} and then perform assertions.
                                      • C. Create all test data, use future in the rest class, then perform assertions.
                                      • D. Create all test data in the test class, use system. runs {} to invoke the trigger, then perform assertions.
