Question 1
A financial services firm is implementing Pega Customer Decision Hub to provide next-best-actions for wealth management clients. The firm needs to integrate real-time stock market fluctuation data from an external API into their decision strategies. The goal is to adjust the suitability of investment product offers based on market volatility. Which sequence of components in a decision strategy is the most efficient and scalable approach to achieve this?
Answer and explanation
Correct answer: D
This is the most efficient approach. It first narrows down the set of potential actions using a Filter component, which reduces the data volume. It then makes a single, targeted real-time API call using a Data Join shape configured with a Connect-REST rule. The retrieved volatility data is then mapped to a property, which is subsequently used in a Decision Table to evaluate suitability. This sequence minimizes external API calls and processes only the relevant propositions, ensuring low latency and high scalability.
