                              Salesforce Sample Questions:

                              Question #1
                              Apex トリガーと Apex クラスは、ケースが変更されるたびにカウンター `Edit_Count__c` を増分します。
                              ```java
                              public class CaseTriggerHandler {
                              public static void handle(List<Case> cases) {
                              for (Case c : cases) {
                              c.Edit_Count__c = c.Edit_Count__c + 1;
                              }
                              }
                              }
                              trigger on Case(before update) {
                              CaseTriggerHandler.handle(Trigger.new);
                              }
                              ```
                              ケースオブジェクトに、ケースの作成または更新時に実行される保存前レコードトリガフローを本番環境に新しく追加しました。このプロセスを追加して以来、ケースの編集時に「Edit_Count__c」が複数回増加しているという報告を受けています。この問題を修正するApexコードはどれでしょうか?

                              A. Edit_Count__c = c.Edit_Count__c + 1;
                              }
                              }
                              }
                              trigger on Case(before update) {
                              if (CaseTriggerHandler.firstRun) {
                              CaseTriggerHandler.handle(Trigger.new);
                              }
                              CaseTriggerHandler.firstRun = false;
                              }
                              ```
                              B. ```java
                              public class CaseTriggerHandler {
                              Boolean firstRun = true;
                              public static void handle(List<Case> cases) {
                              if (firstRun) {
                              for (Case c : cases) {
                              C. Edit_Count__c = c.Edit_Count__c + 1;
                              }
                              }
                              firstRun = false;
                              }
                              }
                              trigger on Case(before update) {
                              CaseTriggerHandler.handle(Trigger.new);
                              }

                              if (CaseTriggerHandler.firstRun) {
                              CaseTriggerHandler.handle(Trigger.newMap);
                              }

                              }

                              }
                              firstRun = false;
                              }
                              ```
                              G. ```java
                              public class CaseTriggerHandler {

                              Question #2
                              開発者は、スマートフォンでは1列、タブレット/デスクトップでは2列で表示するLightning Webコンポーネントを必要としています。開発者はコードにどの部分を追加すればよいでしょうか?

                              A. <lightning-layout-item>要素にsmall-device-size="12"を追加します。
                              B. <lightning-layout-item> 要素に size="12" medium-device-size="6" を追加します。
                              C. <lightning-layout-item> 要素に size="6" small-device-size="12" を追加します。
                              D. <lightning-layout-item>要素にmedium-device-size="6"を追加します。


                              Question #3
                              ある企業のLightningページには、多数のLightningコンポーネントが含まれており、その中には参照データをキャッシュするものもあります。このページに最新の参照データが表示されないという報告を受けています。開発者は、Lightningページの問題を分析・診断するためにどのようなツールを活用すればよいでしょうか?

                              Question #4
                              ある企業は、7年経過後に機密情報を自動的に削除する必要があります。そうなると、毎日約100万件のレコードが削除されることになります。どうすれば実現できるでしょうか?

                              A. 7 年以上前のレコードをクエリして削除するバッチ Apex プロセスを毎日実行するようにスケジュールします。
                              B. 7 年以上前のレコードを照会する @future プロセスをスケジュールし、1,000 件のレコード バッチで自分自身を再帰的に呼び出してそれらを削除します。
                              C. 集計関数を使用して 7 年以上前のレコードを照会し、AggregateResult オブジェクトを削除します。
                              D. SOSL ステートメントを実行して、7 年以上前のレコードを検索し、結果セット全体を削除します。


                              Question #5
                              ある開発者が、反復的なタスクや機能の開発を簡素化するJavaScriptライブラリを作成し、SalesforceにjsUtilsという静的リソースとしてアップロードしました。別の開発者は、新しいLightning Webコンポーネント(LWC)をコーディングしており、このライブラリを活用したいと考えています。LWC内の静的リソースを適切にロードする記述はどれですか?

                              A. <lightning=require scripts="{$Resource.jsUtils}"/>
                              B. import jsUtilities from '@salesforce/resourceUrl/jsUtils';
                              C. const jsUtility = $A.get('$Resource.jsUtils');
                              D. import {jsUtilities} from '@salesforce/resourceUrl/jsUtils';
