Certified Pega Senior System Architect v8.0 (2019) — Question 9

Your application is deployed to the cloud. A data source outside your application populates a data page by using your data access pattern configuration. You receive complaints that the system takes a long time to fetch data each time the case worker accesses information for a different customer.
Which approach solves this performance issue?

Answer options

• A. Move to local installation because network traffic in cloud deployment is often slow.
• B. Change snapshot data access method to reference pattern data access method.
• C. Fetch only the targeted data from the database each time data is needed so access is faster.
• D. Access data page with a predefined key so that, once loaded, data access is faster.

Correct answer: B

Explanation

The correct answer is B because changing to a reference pattern data access method can optimize how data is retrieved, reducing latency. Option A is incorrect as moving to a local installation may not resolve the inherent issues in data access patterns. Option C may improve speed but does not address the underlying access method improvement. Option D, while it might enhance speed for subsequent accesses, does not fundamentally change how the data is fetched initially.
