Name a common way React Native apps store local data.

React Native apps often use AsyncStorage or SQLite to save data locally on the device.

Why is syncing important when using local data for offline experience?

Syncing updates the local data with the server when the internet is back, keeping information accurate and up-to-date.

What is a limitation of relying only on local data?

Local data might get outdated if the app doesn’t sync properly, and it can use device storage space.

What does local data allow a mobile app to do?

A Work without internet connection

B Increase internet speed

C Delete app data automatically

D Require constant server access

Local data lets the app function offline by storing information on the device.

Which React Native tool is commonly used for local data storage?

A Axios

B AsyncStorage

C Redux

D Expo Camera

AsyncStorage is a simple key-value storage system for React Native apps.

What happens when an app syncs local data after going online?

A It updates local data with server changes

B It deletes all local data

C It disables offline mode

D It resets the app settings

Syncing updates local data to match the latest server information.

Why might local data become outdated?

A If the device battery is low

B If the app is uninstalled

C If the user closes the app

D If the app doesn’t sync regularly

Without syncing, local data won’t reflect recent changes from the server.

Which is NOT a benefit of local data?

A Faster access to data

B Offline app use

C Unlimited storage space

D Reduced server load

Device storage is limited, so local data cannot be unlimited.

Explain how local data enables a mobile app to work offline.

Think about what happens when you lose internet but still use an app.

Describe the role of syncing in maintaining local data accuracy.

Consider how your app gets new information after being offline.
