Answer C https://docs.aws.amazon.com/efs/latest/ug/lifecycle-management-efs.html "Amazon EFS lifecycle management automatically manages cost-effective file storage for your file systems. When enabled, lifecycle management migrates files that have not been accessed for a set period of time to the EFS Standard–Infrequent Access (Standard-IA) or One Zone–Infrequent Access (One Zone-IA) storage class, depending on your file system...." "Lifecycle policies for your Amazon EFS file system: AFTER_7_DAYS, AFTER_14_DAYS, AFTER_30_DAYS, AFTER_60_DAYS, AFTER_90_DAYS"

Question is inadequate.. The question does not say "after 7 days" it says after somedays which may also mean 3 days or 30 days there are lot of assumptions to be made... :(

EFS Intelligent-Tiering Transition files to EFS IA based on last access and not based on time after creation. "With intelligent tiering, files in the standard storage class (EFS Standard or EFS One Zone) that are not accessed for the duration of the Transition into IA lifecycle policy setting, for example 30 days, are transitioned to the corresponding Infrequent Access (IA) storage class" "The Transition into IA lifecycle policy has the following values: None 7 days since last access 14 days since last access 30 days since last access 60 days since last access 90 days since last access" https://docs.aws.amazon.com/efs/latest/ug/lifecycle-management-efs.html I think answer should be A

Transitioning files to EFS IA based on last access is a pretty good approach though, it means while its initial usage is occurring it won't be moved, then when the access for the file stops, it gets moved to IA pretty quickly (7 days later).

Amazon Elastic File System Infrequent Access Now Supports a 7-day Lifecycle Management Policy. but why cant we use S3 here ? Bit confused, can someone explain ?

It's in the wording. You can't "mount" a S3 bucket, not at least with AWS' default design (can do that with 3rd party solutions, but of course the exam doesn't cover 3rd party solutions)
