A. Create a Lustre file system through Amazon FSx.

The Lustre file system is an open-source, parallel file system that can be used for HPC applications. Refer to http://lustre.org/ for its introduction. In Amazon FSx, users can quickly launch a Lustre file system at a low cost.
Option​ ​A ​is​ CORRECT:​ Amazon FSx supports Lustre file systems and users pay for only the resources they use.
Option​ ​B ​is​ ​incorrect:​ Although users may be able to configure a Lustre file system through EBS, it needs lots of extra configurations, Option A is more straightforward. 
Option​ ​C ​is​ ​incorrect:​ Because the EC2 placement group does not support a Lustre file system.
Option​ ​D ​is​ ​incorrect:​ Because products in AWS Marketplace are not cost-effective. For Amazon FSx, there are no minimum fees or set-up charges. Check its pricing in Amazon FSx for Lustre Pricing.
