Amazon CloudFront

B.

AWS Global Accelerator

C.

Application Load Balancer (ALB)

Network Load Balancer (NLB)

E.

Amazon API Gateway

How to approach this question

Identify the protocol (UDP) and the need for global routing/static IPs (Global Accelerator).

Full Answer

AWS Global Accelerator and Network Load Balancer.
AWS Global Accelerator improves the availability and performance of applications with local or global users. It provides static IP addresses and supports TCP and UDP. A Network Load Balancer (NLB) must be used behind it, as ALBs do not support UDP.

Common mistakes

Selecting CloudFront, which only supports HTTP/HTTPS/WebSocket (TCP).
