- General purpose performance mode (default) Ideal for latency-sensitive use cases. - Max I/O mode Can scale to higher levels of aggregate throughput and operations per second with a tradeoff of slightly higher latencies for file operations.

D In contrast, Max I/O file systems are suitable for workloads such as data analytics, media processing, and machine learning. These workloads need to perform parallel operations from hundreds or even thousands of containers and require the highest possible aggregate throughput and IOPS 2 keywords matching the question, Throughput and Data analytic https://docs.aws.amazon.com/AmazonECS/latest/bestpracticesguide/storage-efs.html

D for me

B - correct.

for analytics workload

D looks correct

Option D because of High Throughput requirement

from https://docs.aws.amazon.com/efs/latest/ug/performance.html#performancemodes: "Due to the higher per-operation latencies with Max I/O, we recommend using General Purpose performance mode for all file systems."

IOPS is something different than throughput

IOPS is not throughput... General Purpose performance mode has a higher throughput

"Max I/O performance mode has higher per-operation latencies than General Purpose performance mode. For faster performance, we recommend always using General Purpose performance mode" No performance requirement but high I/O in the question.

Option D as Maximum Throughput is primary requirement here.

B seems more appropriate.

think Both B and D are correct.. But I'll go with B coz the hierarchy is general purpose then Max I/O.. - A. Storage Gateway: While providing NFS access to S3, it's not optimized for high throughput or real-time access like EFS, making it less suitable for big data analytics workloads. - C. EBS Volume: EBS volumes can only be attached to a single EC2 instance at a time, limiting their use for shared storage across multiple instances. - D. EFS Max I/O: While offering the highest throughput, it's more expensive than General Purpose mode and might not be necessary for all big data workloads.

D ans What latency, throughput, and IOPS performance can I expect for my Amazon EFS file system? The expected performance for your Amazon EFS file system depends on its specific configuration (for instance, storage class and thoroughput mode) and the specific file system operation type (read or write). Please see the File System Performance documentation for more information on expected latency , maximum throughput, and maximum IOPS performance for Amazon EFS file systems.
