AWS Certified Solutions Architect – Associate (SAA-C02) — Question 246

A solutions architect needs to design a resilient solution for Windows users' home directories. The solution must provide fault tolerance, file-level backup and recovery, and access control, based upon the company's Active Directory.
Which storage solution meets these requirements?

Answer options

• A. Configure Amazon S3 to store the users' home directories. Join Amazon S3 to Active Directory.
• B. Configure a Multi-AZ file system with Amazon FSx for Windows File Server. Join Amazon FSx to Active Directory.
• C. Configure Amazon Elastic File System (Amazon EFS) for the users' home directories. Configure AWS Single Sign-On with Active Directory.
• D. Configure Amazon Elastic Block Store (Amazon EBS) to store the users' home directories. Configure AWS Single Sign-On with Active Directory.

Correct answer: B

Explanation

The correct answer is B because Amazon FSx for Windows File Server offers a fully managed Windows file system that supports Multi-AZ for fault tolerance, integrates with Active Directory for access control, and provides file-level backup and recovery options. Options A and C do not meet all the necessary requirements for fault tolerance and integration with Active Directory, while option D does not provide the required file-level capabilities.
