Google Cloud Digital Leader — Question 221

A retail company stores their product inventory in a legacy system. Often, customers find products on the company's website and want to purchase them in-store.
However, when they arrive, they discover that the products are out of stock.
How could the company benefit from using an application programming interface (API)?

Answer options

• A. To create personalized product recommendations for customers
• B. To optimize their on-premises legacy system stability
• C. By manually linking each inventory system to the website on a case-by-case basis
• D. By programmatically connecting the inventory system to their website

Correct answer: D

Explanation

The correct answer is D because using an API allows the company to automatically sync their inventory system with the website, ensuring that customers see real-time stock levels. Option A focuses on personalized recommendations, which does not address inventory accuracy. Option B is about system stability rather than integration, and option C suggests a manual process that is inefficient and prone to errors.
