You are the Solutions Architect for a health insurance service company that wants to start building and supporting IoT devices for patients who recently signed new clauses in the contract. This will open opportunities to expand its market but also introduces some restrictions. All services and data involved have to guarantee HIPAA compliance and include in-transit encryption. Due to high sensitivity data, bypassing the internet is crucial. The architecture uses already ELBs. They want to avoid DNS re-configuration and IP address caching when it comes to the IoT devices. What combination of services may be the closest option to address this challenge?

Answer options:

A.AWS ELBs, AWS IoT, and Amazon Route53 configured with geolocation or latency routing policies. This requires an interface endpoint (PrivateLink) for Route53 to stay inside the AWS backbone.
B.AWS ELBs, AWS IoT, and AWS Global Accelerator which provisions two anycast static IP addresses.
C.AWS ELBs, AWS IoT, and Amazon Route53 configured with geolocation or latency routing policies. This does not require an interface endpoint (PrivateLink) because Route53 is inside the AWS backbone.
D.AWS ELBs, AWS IoT, and AWS Global Accelerator which provisions one anycast static IP address.

Answer: B
AWS Global Accelerator allocates two IPv4 anycast static IP addresses and keeps the traffic inside the AWS globally redundant network.
Option A is incorrect because there is no interface endpoint for Amazon Route53.
Option C is incorrect because Amazon Route53 is not inside the AWS backbone.
Option D is incorrect because AWS Global Accelerator provides two anycast static IP addresses.
