As a Solutions Architect, you are working with system and networking teams. You are assigned to provide disaster recovery (DR) and high-availability elements for a security planning document involving FSx for Windows. What assertions are true about Amazon FSx for Windows File Server? (Select TWO)

Answer options:

A.Amazon FSx for Windows File Server offers instant regional failover, fault-isolating design, and automatic traffic routing across multiple applications, multiple VPCs, accounts, or Regions.
B.Amazon FSx for Windows File Server allows to access file systems from multiple Amazon Virtual Private Clouds (VPCs), AWS accounts, and AWS Regions via VPC Peering or AWS Transit Gateway. 
C.Amazon FSx for Windows File Server offers single-AZ and multi-AZ deployment options with SSD and HDD storage options.
D.Direct Connect, VPN, VPC Peering, and AWS Transit Gateway are not supported.
E.Amazon FSx for Windows File Server is a fully POSIX-compliant filesystem.

Answers: B and C
As of 2019, Amazon FSx for Windows File Server supports access across VPCs, accounts, and Regions via Direct Connect or VPN (on-premises) and VPC Peering or AWS Transit Gateway.
You can share your file data sets across multiple applications, internal organizations, or environments spanning multiple VPCs, accounts, or Regions using inter-VPC, inter-account, and inter-Region access. 
Single-AZ files ensure high availability within a single Availability Zone (AZ) by automatically detecting and addressing component failures. In addition, Multi-AZ file systems provide high availability and failover support across multiple Availability Zones by provisioning and maintaining a standby file server in a separate Availability Zone within an AWS Region.
Option A is incorrect because those benefits are part of the AWS Global Accelerator networking service.
Option D is incorrect because Direct Connect or VPN (on-premises) and VPC Peering or AWS Transit Gateway are supported.
Option E is incorrect because Amazon FSx for Windows File Server is not POSIX-compliant —Amazon FSx for Luster is POSIX-compliant.
