NEW QUESTION # 99
Universal Charities (UC) は、Salesforce を使用して個人や法人からクレジット カード引き落としの形で電子寄付を集めています。
カスタマー サービス エージェントがクレジット カード情報を入力すると、寄付が処理されるようにその情報が 8 つのサードパーティ決済プロセッサに送信される必要があります。UC は個人向けに 1 つの決済プロセッサを使用し、法人向けには別の決済プロセッサを使用します。
システム管理者が展開後に必要に応じて設定を変更できるように、開発者はさまざまな決済プロセッサの設定を保存するために何を使用する必要がありますか?
Answer: B
Explanation:
Hierarchy custom setting is a way of storing the payment processor settings for the different payment processors, so that the system administrator can modify the settings once they are deployed, if needed. Hierarchy custom setting is a type of custom setting that can store configuration data that can vary for different users or profiles. Hierarchy custom setting can be accessed from Apex code, and can be used to control the behavior of the code based on the user's context. By using hierarchy custom setting, the developer can create a custom setting that can store the payment processor URL and credentials for the individual and corporate customers. The developer can then use the custom setting in the Apex code to determine which payment processor to use based on the user's profile or identity. The system administrator can also change the custom setting values in the user interface, without modifying the code, if the payment processor settings change.

NEW QUESTION # 100
次のコード スニペットを考えてみましょう。
Apex メソッドはアカウントのデータ量が多い環境で実行されており、クエリのパフォーマンスが低下しています。
結果セット全体を保持しながらクエリを最適に実行するには、開発者はどの手法を実装する必要がありますか?
Answer: C
Explanation:
When dealing with large data volumes in Salesforce and ensuring optimal performance for queries, it's important to choose an approach that both handles the data volume efficiently and retrieves the complete result set.
* Option D is correct because using the Database.QueryLocator method is a best practice for handling large data volumes. It is typically used with batch Apex, which can process records in batches, thus reducing the likelihood of hitting governor limits. It's designed to handle very large data sets that would otherwise exceed normal SOQL query limits.
* Option A is incorrect because creating a formula field doesn't improve the performance of the query. It simply creates a new field that combines existing data, but it does not inherently optimize the query execution.
* Option B is incorrect because breaking down the query into two parts and joining them in Apex could potentially be less efficient and would require additional code to manage the combined result sets. This approach does not leverage the built-in Salesforce features designed to handle large data volumes.
* Option C is incorrect because the @Future annotation makes the method execute asynchronously, but it does not help with query performance or large data volume management.

NEW QUESTION # 101
開発者は、lightning-record-edit-form を使用してリードに関する情報を収集する Lightning Web コンポーネントを作成しました。ユーザーは、潜在顧客レコードを保存しようとすると、入力に関するエラー メッセージが一度に 1 つしか表示されないと不満を抱いています。
JavaScript の介入を最小限に抑えながら、複数のフィールドで検証を実行し、複数のエラー メッセージを同時に表示するための推奨されるアプローチは何ですか?
Answer: B
Explanation:
Salesforce validation rules are declarative and can be used to validate more than one field on an object and display multiple error messages. This approach requires minimal JavaScript code and uses Salesforce's built-in validation framework. References:

NEW QUESTION # 102
開発者はテストの失敗をサンドボックスで確認しますが、本番環境では確認しません。サンドボックスの作成以来、どちらの環境にもコードやメタデータの変更は積極的に加えられていません。
問題を解決するにはどの考慮事項を確認する必要がありますか?
Answer: D
Explanation:
If test failures are occurring in a sandbox but not in production and there have been no active code or metadata changes, it could be due to differences in the Salesforce release versions between the two environments.
Sandboxes can be on preview instances which get upgraded to new releases before production instances. This can lead to differences in behavior and could affect test executions. Ensuring that both the sandbox and production are on the same release can resolve such issues. API version differences and parallel testing settings typically do not cause discrepancies if the code hasn't changed, and while using SeeAllData=true is generally not recommended due to its dependence on the organization's data, it's unlikely to be the cause if the issue is related to the environment rather than the data.
