Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 394 discussion

- 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 is right

Option D is the correct answer because Amazon Elastic File System (Amazon EFS) with Max I/O performance mode meets all the requirements for the big data analytics cluster. EFS provides highly available, resilient, and POSIX-compatible file storage replicated across multiple Availability Zones. Max I/O mode offers high levels of throughput and IOPS required for high-performance workloads like big data analytics. By mounting the EFS file system on each EC2 instance in the cluster, all nodes can access the common file storage with read and write capabilities, enabling seamless collaboration and data sharing across the distributed cluster. Option B (Amazon EFS General Purpose performance mode): The General Purpose performance mode is suitable for most file system workloads but may not provide the high levels of throughput required for big data analytics workloads.

B is the correct answer, Max I/O mode is the legacy version available, for best performance AWS recommends using default mode which is general purpose. https://docs.aws.amazon.com/efs/latest/ug/performance.html#performancemodes

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.
