Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply a filter to the gallery data source
Applying a filter to the gallery data source reduces the number of records loaded into the gallery, which improves performance because fewer records need to be transferred and rendered. Option A (non-delegable query) would actually worsen performance by loading all records locally. Option B (converting to a model-driven app) is a significant redesign and not a simple performance fix. Option D (increasing gallery height) does not affect the amount of data loaded; it only changes the display area.
