Certified Pega Senior System Architect v8.0 (2019) — Question 23

The page .Product contains data retrieved from an external system of record using a data page.
How do you ensure .Product always contains the most current data from the data page?

Answer options

• A. Select Refer to a data page on .Product.
• B. Select Copy data from a data page on .Product.
• C. Configure .Product to refer to a keyed data page.
• D. Define a reference property that refers to the data page.

Correct answer: D

Explanation

The correct answer is D because defining a reference property that points to the data page ensures that .Product always fetches the most updated data. Options A and B do not guarantee current data retrieval as they either refer to static data or copy data at a single point in time. Option C only allows access to data from a keyed data page but does not ensure it is the latest information.
