PL-900 Demonstrate the capabilities of Power Apps Practice Question
This PL-900 practice question tests your understanding of demonstrate the capabilities of power apps. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Contoso, Ltd. is a multinational company with a global sales team. They use Microsoft Power Apps to build a model-driven app for managing customer accounts and opportunities. The app uses Microsoft Dataverse as the data source. The sales team accesses the app on mobile devices while traveling. Recently, users have reported that the app is slow when loading large numbers of opportunities. The app has a custom page that displays a list of all opportunities without any filters. The page uses a gallery that loads all records at once. The app also uses several custom connectors to external systems, but the slowness is primarily observed when loading the opportunities list. The IT team has confirmed that the Dataverse environment is in the same region as the users, and network latency is not an issue. They need to improve the performance of the app. Which two actions should the IT team take? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement delegation in the gallery to filter data on the server
Option B is correct because implementing delegation in the gallery to filter data server-side reduces the amount of data transferred. Option D is correct because adding a search box to filter records locally (but with delegation) improves performance. Option A is wrong because increasing Dataverse capacity does not address query performance. Option C is wrong because using a canvas app might not solve the underlying data loading issue. Option E is wrong because disabling real-time sync is not recommended and may cause data inconsistency.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Disable real-time synchronization with Microsoft Entra ID
Why it's wrong here
Entra ID sync is unrelated to app performance.
✗
Replace the model-driven app with a canvas app
Why it's wrong here
Both app types use similar data loading; the issue is delegation.
✗
Increase the Dataverse storage capacity
Why it's wrong here
Storage capacity does not affect query performance.
✓
Implement delegation in the gallery to filter data on the server
Why this is correct
Delegation ensures large datasets are processed server-side, improving performance.
Related concept
Static NAT maps one inside address to one outside address.
✓
Add a search box to filter the gallery by using a delegable filter
Why this is correct
Filtering with delegation reduces data load.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Similar concept trap
Both app types use similar data loading; the issue is delegation.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PL-900 NAT questions on configuration and troubleshooting.
