PL-900 A sales team uses a Canvas app to track leads Practice Question

A sales team uses a Canvas app to track leads. Users report that the app loads slowly when accessing on mobile devices. Which component should be optimized to improve performance?

⚠ Common exam trap

Many candidates confuse cosmetic or metadata changes (version, icon, color) with performance optimizations, overlooking that data source efficiency is the root cause of slow loading in Canvas apps on mobile devices.

Correct answer & explanation

✓

Optimize data source connections and queries

Optimizing data source connections and queries directly reduces the amount of data transferred and the number of round trips between the Canvas app and its data source (e.g., Dataverse, SharePoint, SQL). On mobile devices, network latency and bandwidth are often constrained, so inefficient queries (e.g., loading all records instead of using filters) cause significant slowdowns. This is the primary performance lever for Canvas apps, as per Microsoft's guidance on app optimization.
