You are planning to create a VPC endpoint for your SaaS product hosted in AWS. You will provide this link to a customer who will access the link from their application. The application works on the UDP protocol. You plan to provide the DNS name for the link to them. But the customer is not able to use the link from within their application. What could be the issue?

Answer options:

A.The gateway endpoint has a policy that denies access. This should be modified accordingly.
B.The service endpoint only works on the TCP protocol.
C.The customer needs to create a Network load balancer to access the endpoint service.
D.The customer needs to use a NAT device to access the endpoint service.

Answer – B
This is mentioned as one of the limitations for Endpoint Services in the AWS Documentation.
Option A is incorrect since this is an interface and not a gateway.
Options C and D are incorrect since you don’t need a NAT device or Network Load Balancer to access the service.
