NEW QUESTION # 149
非同期 Apex を使用することによってのみ実行できるユースケースはどれですか?
Answer: D
Explanation:
Making a callout from an Apex trigger is not allowed synchronously; hence, such callouts must be performed in an asynchronous context. The only way to perform this within the Salesforce platform is by using asynchronous Apex, such as @future methods or Queueable Apex.References: Apex Developer Guide - Asynchronous Apex
NEW QUESTION # 150
組織内にApexコントローラとVisualforceページがあり、ユーザーが選択した選択リスト値の組み合わせで構成されるカスタムフィルタを使用してレコードを表示しています。一部の入力組み合わせではページが結果を表示するのに時間がかかりすぎ、他の入力選択肢では「ビューステートの最大サイズ制限を超えました」という例外が発生します。開発者はこの問題を解決するためにどのような手順を踏むべきでしょうか？
Answer: A
Explanation:
The two symptoms described-slow load times and "Maximum view state size limit exceeded"-are both caused by Large Data Volumes (LDV) being handled improperly in the UI. When a user selects a filter that returns thousands of records, the SOQL query takes longer to execute, and the resulting list is stored in the controller's memory. Because Visualforce serializes all non-transient controller variables into a hidden form field (the View State), large lists quickly exceed the 135KB limit.
The correct resolution is to implement Pagination (Option D). By using the StandardSetController, a developer can easily manage large sets of data by loading only a small subset (e.g., 20 records) into the View State at a time. Users can then navigate through "Pages" of data. Alternatively, adding a LIMIT to the SOQL query prevents the application from attempting to process more data than the platform limits allow.123 Option A is incorrect because picklist fields can be indexed by Salesforce Support or if they are part of a custom index. Option B is the opposite of what is neede4d; adding transient reduces the View State. Option C adds unnecessary complexity without addressing the underlying data volume issue. Using a StandardSetController provides a built-5in, effi6cient way to handle large result sets while keeping the View State small and the page responsive.

NEW QUESTION # 152
Apex トリガは、2 人の営業担当者が商談を獲得するたびに、注文共同レコードを作成します。最近、トリガは 2 つの注文を作成しています。
2 人の開発者がこれをトラブルシューティングするための最適なテクニックは何ですか?
Answer: B
Explanation:
The optimal technique for the developer to troubleshoot this issue is to add system.debug() statements to the code and use the Developer Console logs to trace the code. system.debug() is a method that prints a message to the debug log, which is a tool that captures information about the execution of the code. The Developer Console is an integrated development environment that allows the developer to access and analyze the debug logs. By adding system.debug() statements to the code, the developer can print the values of variables, the execution flow, and the errors and exceptions that occur during the trigger execution. By using the Developer Console logs, the developer can view and filter the debug messages and identify the cause of the issue. This way, the developer can troubleshoot the issue effectively and efficiently . Reference: [system.debug Method], [Debug Logs], [Developer Console]
