A company wants to host a selection of MongoDB instances. They are expecting a high load and want to achieve high performance. As an architect, you need to ensure that the right storage is used to host the MongoDB database. Which of the following would you incorporate as the underlying storage layer?

Answer options:

A.Provisioned IOPS SSD
B.General Purpose SSD
C.Throughput Optimized HDD
D.Cold HDD

Answer – A
The below snapshot from the AWS Documentation shows the different volume types and why Provisioned IOPS is the most ideal for this requirement.
Also, Provisioned IOPS is recommended for NoSQL and Relational Databases.
Because of what is mentioned in the documentation as the ideal storage type, the other options are invalid.
