質問 # 141
A developer is writing a Visualforce page that queries accounts in the system and presents a data table with the results. The users want to be able to filter the results based on up to five fields. However, the users want to pick the five fields to use as filter fields when they run the page.
Which Apex code feature is required to facilitate this solution?
正解：D
解説：
The requirement described in the question calls for a flexible way to query records based on user-selected fields. Dynamic SOQL is the perfect tool for this job as it allows the construction of a SOQL string at runtime, which can include any number of fields and filter conditions that are determined at the time the user interacts with the page. This enables the creation of a highly customizable query interface. A, B, and C are not suitable for this requirement as they serve different purposes: A (Streaming API) is for receiving real-time streams of data changes, B (Metadata API) is for managing the metadata of your Salesforce org, and C (variable binding) is used in Visualforce to bind data between the page and the controller but does not provide dynamic query capabilities.

正解：C、D、E
解説：
Lazy loading improves performance by loading data only when needed.
Lightning Data Service (LDS) handles data operations and caching efficiently.
Using {Cacheable=true} on Apex methods enables the Lightning Component framework to cache the method's return value, reducing server round-trips for the same data.
