                                      質問 # 120
                                      An Apex class does not achieve expected code coverage. The testsetup method explicitly calls a method In the Apex class..
                                      How can the developer generate the code coverage?

                                      正解：C

                                      解説：
                                      When an Apex class does not achieve the expected code coverage, it suggests that the test methods are not executing parts of the class. The @testvisible annotation can be used to increase code coverage by allowing test methods to access private or protected members of another class. This enables the test method to call methods that may not be directly accessible, but it is not a direct means to generate code coverage. The code coverage is actually achieved when the test methods execute the code within these methods. Therefore, to properly generate code coverage, the developer must ensure that the test methods call the relevant portions of the code that need to be covered. The use of @testvisible can facilitate this process by making otherwise inaccessible code available for testing.

                                      質問 # 121
                                      A corporation has many different Salesforce orgs, with some different objects and some common objects, and wants to build a single Java application that can create, retrieve, and update common object records in all of the different orgs.
                                      Which method of integration should the application use?

                                      正解：B

                                      解説：
                                      The SOAP API with the Partner WSDL is ideal for building integrations that work across multiple Salesforce orgs, especially when they have varying schemas. The Partner WSDL is designed to be flexible and dynamic, catering to different metadata.


                                      質問 # 122
                                      Which two queries are selective SOQL queries and can be used for a large data set of 200,000 Account records?
                                      Choose 2 answers

                                      正解：B、D

                                      解説：
                                      Selective queries in SOQL are optimized for performance. Query B is selective because it filters out empty names, which are likely to be less in number. Query C is selective if the list of names is small, and 'Customer_Number_c' is indexed or can be used as an external ID field. Working with Very Large SOQL Queries


                                      質問 # 123
                                      A developer created the following test method:

                                      The developer org has five accounts where the name starts with "Test". The developer executes this test in the Developer Console. After the test code runs, which statement is true?

                                      正解：D

                                      解説：
                                      Since the SeeAllData=true annotation is used, the test class does not have its own test data and is relying on the data in the org. The org already has accounts with the name starting with "Test", so the assertion that no accounts should exist after the deletion will fail because the test method only deletes the account that was created within its scope.

                                      質問 # 124
                                      A Visuzlforce page loads slowly due to the large amount of data it displays.
                                      Which strategy can a developer use to improve the performance?

                                      正解：B

                                      解説：
                                      Lazy loading is a strategy to improve the performance of a Visualforce page that loads a large amount of data. By loading the data on demand, rather than in the controller's constructor, the initial page load is faster, and additional data is only loaded when necessary.
