Free Actual Microsoft Azure AZ-204 Actual Exam Questions - Question 15 Discussion
HOTSPOT A company is developing a mobile app for field service employees using Azure App Service Mobile Apps as the backend. The company’s network connectivity varies throughout the day. The solution must support offline use and synchronize changes in the background when the app is online app. You need to implement the solution. How should you complete the code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. 
I think the key part here is that the app needs to work offline and sync changes back when online, so you definitely need both PushAsync and PullAsync. Without PushAsync, any local changes wouldn’t be sent to the server, which messes up the sync. InitializeLocalStoreAsync is also necessary to set up offline storage before syncing. So, the best combo is InitializeLocalStoreAsync, then PushAsync, then PullAsync. Skipping any one of these would break complete offline sync functionality.
The key is the app needs to sync changes both ways. So calling PushAsync to send local updates and PullAsync to get server changes makes sense here. Just one wouldn’t fully cover offline syncing.
I’d say both PushAsync and PullAsync are needed here. PushAsync handles sending local changes to the server, while PullAsync pulls down any server updates. Just PullAsync wouldn’t sync local edits properly, and just PushAsync wouldn’t update local data. Also, setting up the local store is crucial to support offline mode, so the code part about InitializeLocalStoreAsync needs to be included. That combo matches the offline sync model for Azure Mobile Apps, so looks like completing the segment with both sync calls and local store initialization is the way to go.
I think using PullAsync for syncing makes sense since it updates local data from the server. But without PushAsync, local changes might not get uploaded, so maybe both calls are needed for full sync.
I’d go with local store for offline and PullAsync for syncing data in background. Seems to fit the offline-first approach here.
