                              ある企業は Dpportunities を使用して顧客への売上を追跡しており、その組織には何百万もの Opportunities があります。彼らは、関連する収益オブジェクトを通じて経時的な収益の追跡を開始したいと考えています。
                              初期実装の一環として、複雑なロジックに基づいて商談の収益レコードを自動的に作成してデータを入力することにより、データの 1 回限りのシード処理を実行したいと考えています。
                              彼らは、約 100,000 の商談で収益レコードが作成され、入力されると推定しています。

                              Answer: C

                              Explanation:
                              For a one-time bulk operation on a large data set, using a Database.Batchable class is the best approach. This allows complex logic to be processed in manageable chunks and efficiently manages system resources.

                              NEW QUESTION # 87
                              以下の Aura コンポーネントを参照してください。
                              HTML
                              <aura:component>
                              <aura:attribute name="contactInfo" type="Object"/>
                              <aura:attribute name="showContactInfo" type="boolean" default="true"/>
                              <aura:handler name="init" value="{!this}" action="{!c.init}"/>
                              <aura:if isTrue="{!v.showContactInfo}">
                              <c:contactInfo value="{!v.contactInfo}"/>
                              </aura:if>
                              </aura:component>
                              開発者は、コンポーネントの読み込みが遅いという苦情を受けました。コンポーネントのパフォーマンスを向上させるために、開発者はどのような変更を加えることができますか？

                              Answer: C

                              Explanation:
                              In Aura components, the <aura:if> tag is "lazy." It does not instantiate or render the components within its body until its isTrue expression evaluates to true. In the provided code, showContactInfo is defaulted to true.
                              This means that when the parent component begins its initialization, it immediately starts creating and rendering the child component <c:contactInfo> simultaneously.
                              By changing the default for showContactInfo to "false" (Option C), the developer implements a "Lazy Loading" pattern. The parent component will load quickly because it skips the heavy lifting required to render the child. The init handler then runs, retrieves the necessary data, and sets the boolean to true only when the data is ready. This improves the "perceived performance" and the Initial Page Load time.
                              Option A is incorrect because it increases the complexity and weight of the parent component, likely making it slower. Option B (changing to a Map) does not fundamentally affect the rendering engine's speed. Starting with the display attribute as false ensures the browser only renders what is absolutely necessary during the critical first few milliseconds of the page load.
