NEW QUESTION # 139
開発者は、フィールド履歴追跡に依存する asccuntRisteryManager という名前のクラスを作成しました。このクラスには getaccountHistory という静的メソッドがあり、このメソッドは Account にパラメーターとして含まれ、関連付けられた accountHistory オブジェクト レコードのリストを返します。
次のテストは失敗します。
このテストに合格するには何をすべきでしょうか?
Answer: D
Explanation:
The best way to make this test pass is to use Test.isRunningTest() in getAccountHistory() to conditionally return fake AccountHistory records. This way, the developer can bypass the dependency on the field history tracking feature, which is not available in test context, and return some mock data that can be used for the assertion. Creating AccountHistory records manually in the test setup and writing a query to get them will not work, as the AccountHistory object is read-only and cannot be inserted. Using @isTest(SeeAllData=true) to see historical data from the org and query for AccountHistory records will not work, as this annotation is not recommended and might cause unpredictable test results. The test method should not be deleted, as this code can be tested with some modifications. Reference: [Testing Field History Tracking], [Test Class Best Practices], [Apex Developer Guide]

NEW QUESTION # 142
開発者は、取引先の最近連絡した 5 人の取引先責任者を表示する取引先レコードページの Lightning Web コンポーネントを作成しました。Apex メソッド Contacts は連絡先のリストを返し、コンポーネントのプロパティに関連付けられます。
Apex メソッドを接続できるようにするには、上記のコードのどの 2 行を変更する必要がありますか?
2 つの答えを選択してください
Answer: C,D
Explanation:
To make an Apex method callable from a Lightning Web Component, you need to annotate the method with
@AuraEnabled and mark it as cacheable if it's only retrieving data without modifying it. Additionally, the method must be public to be accessible from the component.
* Line 04: Needs @AuraEnabled(cacheable=true) to allow the method to be called from the Lightning Web Component and indicate that the method doesn't modify any data, making it suitable for caching.
* Line 09: The method getFiveMostRecent should not be private because private methods cannot be called from a Lightning Web Component. Changing it to public (or default, which is equivalent to public within the same namespace) is required.

NEW QUESTION # 143
開発者は、単一のトランザクションでレコードの複数のリストを挿入、更新、削除しており、エラーによってすべての実行が妨げられることを確認したいと考えています。
これを処理するには、開発者はコードにエラー例外処理をどのように実装する必要がありますか?
Answer: C
Explanation:
Using Database.setSavepoint() and Database.rollback() within a try-catch statement is the recommended approach for handling transactions that involve multiple DML operations. This allows the developer to roll back all changes if an error occurs, ensuring that partial changes are not committed to the database.
