C. Mongo DB

The correct answer is C. Mongo DB. PIOPS (Provisioned IOPS) EBS volumes are designed for applications that require low-latency and consistent I/O performance. They are a good fit for database workloads that require high I/O operations, such as MongoDB, which often have demanding read and write patterns. Option A, Analytics, typically involves processing large volumes of data and may benefit more from high throughput rather than consistent low-latency I/O provided by PIOPS volumes. Option B, System boot volume, doesn't necessarily require the high I/O performance offered by PIOPS volumes. Standard EBS volumes are typically sufficient for boot volumes. Option D, Log processing, can vary depending on the specific requirements of the log processing application. If the application heavily relies on I/O operations, such as writing and reading log files

C correct

C. Fast EBS = > DB. Analytics - > you better use storage Booting - > Non sense.

C. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volume-types.html "...Provisioned IOPS SSD (io1 and io2) volumes are designed to meet the needs of I/O-intensive workloads, particularly database workloads, that are sensitive to storage performance and consistency..."

https://www.google.com/amp/s/www.parkmycloud.com/blog/ebs-volume-types/amp/ Though not official, it seems database is a good use case of provisioned IOPS.

Question is not clear. gp2 and gp3 are used for boot volumes. io1 and io2 are used for intensive database workload. st1 for log processing https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AmazonEBS.html

b is correct. Only sad cloud use for boot volume
