Free Cisco 350-901 Actual Exam Questions - Question 6 Discussion
DRAG DROP Drag and Drop the application requirement on the left onto the database type that should be selected for the requirement on the right. 
Product catalog fits best with A since it needs strong schema and relationships. Session data is a clear match for C because it prioritizes speed over complex queries. Customer profiles seem flexible, so B works well there.
I’d go with A for product catalog since structured queries and relationships matter most there. Session data fits C because it’s all about fast reads/writes, and B suits customer profiles for flexible, semi-structured info.
Customer profiles to B since documents handle flexible user info better than strict tables.
I’d swap customer profiles to A because they usually have well-defined fields and relationships, making a relational DB a better fit than B. Session data definitely feels like a good match for C given its speed needs.
I’m thinking the product catalog fits better with a relational DB since it likely has structured data and relationships, so option A makes sense there. For session data, which is more ephemeral and might need fast read/write without complex joins, option C looks like a good fit with NoSQL. Customer profiles can be complex but still benefit from relational structure, so option B seems right for that. This setup covers different needs pretty well without mixing up what each DB type is built for.
B for customer profiles, C for session data, A for product catalog.
