問題文
A mobile app's home screen is slow because it makes many separate calls straight to several systems of record. Which root cause and remedy fit best?
選択肢
- The slowness is caused by having any API layer, so removing all APIs and querying the databases straight from the phone would make it respond more quickly.
- The app makes too few calls, so having it open even more separate direct connections to each system of record on every single screen load would render it faster.
- A slow mobile screen that calls many systems directly cannot be improved, with the result that the app's users simply have to wait for the screen.
- The app calls systems of record directly with no tailored layer; an Experience API that combines and shapes the data into one call would speed it up.
