Arcitura Education C90.02 Exam - Topic 6 Question 122 Discussion

Actual exam question for Arcitura Education's C90.02 exam

Question #: 122
Topic #: 6

We exported data from our on-premise relational database to a cloud-based non-relational database. After the export, we noticed that the size of the cloud-based database was significantly larger than our on-premise database. What is the likely reason that the database size increased?

Select the correct answer.

AThe transmission of the data over a wide area network resulted in the accumulation of additional meta data from HTTP headers that was stored in the non-relational database, resulting in the increase in data received by the cloud.

BThe data in the relational database was normalized and became denormalized after being exported into a non-relational database.

CIn order to support higher levels of scalability, the cloud-based database is required to add state data to the non-relational data it stores. This state data is used to synchronize instances of the database tables during runtime usage, but also increases the size of the overall database.

DAll of the above.

I remember discussing how normalization affects database size, so option B seems plausible. But I'm not entirely sure if denormalization always leads to a size increase.
