Which three approaches should a developer implement to obtain the best performance for data retrieval when building a Lightning web component? Choose 3 answers

Show Suggested Answer Hide Answer
Suggested Answer: A, C, E

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.
