NEW QUESTION # 114
ある企業には現在、外部の注文管理システム (OMS) から Salesforce に注文を手動でアップロードするプロセスがあります。
ID を取得するにはアカウントを Salesforce からエクスポートする必要があるため、これは労働集約的なプロセスです。注文を対応するアカウントに関連付けるには、アップロード ファイルを正しいアカウント ID で更新する必要があります。
このプロセスをより効率的にするための 2 つの推奨事項はどれですか?
2 つの答えを選択してください
Answer: A,B
Explanation:
Setting unique fields on related objects as External IDs allows for the creation of relationships during imports without needing Salesforce IDs. The upsert operation in Data Loader can then use these External IDs to relate records, which streamlines the process and avoids the need to export Salesforce IDs manually.

NEW QUESTION # 116
ある会社にはカスタム オブジェクト Order__c があり、そのオブジェクトにはカスタム選択リスト フィールド Status__c があり、その値は「New」です。
「進行中」または「完了」と検索フィールド、
Contact__c、連絡先へ。
「履行された」注文がないすべての取引先責任者レコードの一意のリストを返す SOQL クエリはどれですか?
Answer: A
Explanation:
The correct SOQL query to return a unique list of Contact records that have no 'Fulfilled' Orders is one that selects Ids from the Contact object where the Contact Id is not in the set of Contact Ids related to 'Fulfilled' Orders. This is done by a subquery that selects the Contact__c field from the Order__c records where the Status__c is 'Fulfilled'.

NEW QUESTION # 117
開発者は、Apexベースの注文作成プロセスをデバッグしています。このプロセスでは、プロセスの最終実行前に、SP1、SP2、SP3（順番に作成）の3つのセーブポイントが必要です。最終実行プロセス中に、開発者は特定の条件でSP1にロールバックするルーチンを用意しています。条件が解決されると、コードはSP3へのロールバックを呼び出し、最終実行を続行します。しかし、SP3へのロールバックが呼び出されると、ランタイムエラーが発生します。なぜ開発者はランタイムエラーを受け取るのでしょうか？
Answer: B
Explanation:

Salesforce uses Database.Savepoint objects to manage transaction integrity, allowing developers to roll back the database state to a specific point in time without aborting the entire transaction. However, savepoints follow a strict "stack" logic.8 When you create savepoints in sequence (SP1, then SP2, then SP3), they exist in a linear timeline.91011 When a developer executes a Database.rollback(SP1), the system reverts the database state to exactly how it was when SP1 was created. A critical side effect of this operation is that any savepoints created after the target savepoint are immediately destroyed and invalidated. Because SP3 was created after SP1,12 rolling back to SP1 clear13s SP3 from the transaction's memory. Therefore, any subsequent attempt to call Database.
rollback(SP3) will result in a runtime error because SP3 no longer exists.
To fix this logic, once the code rolls back to SP1 and addresses the condition, it would need to proceed forward through the logic again and potentially set new savepoints if needed. You cannot "jump back forward" to a later savepoint once an earlier one has been invoked, as the rollback has effectively erased the timeline that led to the later savepoints. Understanding this linear invalidation is essential for managing complex nested transactions in Apex.
NEW QUESTION # 118
開発者は、連絡先用および調査応答 c と呼ばれるカスタム オブジェクト用にシステムに入力された電子メール アドレスが、ブロックされたドメインのリストに属していないことを確認する任務を負っています。
ブロックされたドメインのリストは、ユーザーによるメンテナンスを容易にするためにカスタム オブジェクトに保存されます。アンケートの応答 c オブジェクトは、カスタム Visualforce ページを介して設定されます。
これを実装する最適な方法は何ですか?
Answer: C
Explanation:
The optimal way to enforce the exclusion of blocked domains for email addresses entered into Contacts and a custom object is to use a helper class. The class can be called by an Apex trigger on the Contact object and from the controller of the custom Visualforce page used for the Survey Response. This centralizes the logic for maintainability and reusability.
