Ultimate access to all questions.
A company operates a web application across eight AWS Regions, with the application hosted on multiple compute resources behind an Application Load Balancer (ALB) in each Region. Each Region currently uses a different domain, and each ALB is configured to accept only HTTPS traffic using certificates from AWS Certificate Manager (ACM). The company aims to simplify the application's web presence by using a single domain for all Regions while minimizing latency for end users.
Which three actions should a network engineer take to meet these requirements?
A
Use ACM to create an SSL/TLS certificate in the us-east-1 Region for the new domain.
B
Set up latency-based routing in Amazon Route 53 for the new domain. Add the ALBs from all the Regions as targets.
C
Create an alias record for the accelerator in Amazon Route 53 for the new domain.
D
Create a standard accelerator in AWS Global Accelerator. Configure a listener for TCP traffic. Add all the ALBs as targets for the listener.
E
Use ACM to create an SSLITLS certificate for each Region. Configure all the ALBs to use the certificate in their respective Regions.
