Answer: A
Explanation:
A sharing rule can be used to automatically give Read access to a user specified in a lookup field. Sharing rules are declarative and can be based on criteria such as the value of a lookup field. This can be done without writing code and is maintainable through the Salesforce UI.References: Salesforce Help - Sharing Rules

NEW QUESTION # 59
開発者は、取引先の最近連絡した 5 人の取引先責任者を表示する取引先レコードページの Lightning Web コンポーネントを作成しました。Apex メソッド Contacts は連絡先のリストを返し、コンポーネントのプロパティに関連付けられます。
Apex メソッドを接続できるようにするには、上記のコードのどの 2 行を変更する必要がありますか?
2 つの答えを選択してください
Answer: A,D
Explanation:
To make the Apex method able to be wired, the developer should change two lines in the code: add public to line 04, and add @AuraEnabled(cacheable=true) to line 03. Adding public to line 04 makes the Apex method accessible from outside the class, which is required for the @wire decorator to invoke the method. Adding @AuraEnabled(cacheable=true) to line 03 makes the Apex method cacheable, which means that the method can be invoked by a Lightning web component that uses the @wire decorator. This also improves the performance of the component, as it reduces the number of server trips and leverages the client-side cache. The developer should use this annotation for methods that return data that does not change frequently or does not depend on the user context. Adding @AuraEnabled(cacheable=true) to line 08 is not necessary, as the cacheable attribute only applies to the top-level method that is invoked by the @wire decorator, not to the helper methods that are called within the class. Removing private from line 09 is not necessary, as the helper method can be private as long as it is called from within the class. Reference: [Call Apex Methods from Lightning Web Components], [Marking Methods as Storable or Cacheable]
