So, the correct option is: B. Subscribe to AWS Shield Advanced. Add the EC2 instances as resources to protect. Here's why this option is the most appropriate: A. While you can add the accelerator as a resource to protect with AWS Shield Advanced, it's generally more effective to protect the individual resources (in this case, the EC2 instances) because AWS Shield Advanced will automatically protect resources associated with Global Accelerator

Which EC2 instance? Global Accelerator works by providing anycast IP addresses for the underlying resource (our EC2 in this case) so every end user trying to reach the EC2 server HAS to go through the Global Accelerator which is why the Global Accelerator needs to be protected and not the EC2.

Selected Answer: A
AWS Shield is a managed service that provides protection against Distributed Denial of Service (DDoS) attacks for applications running on AWS. AWS Shield Standard is automatically enabled to all AWS customers at no additional cost. AWS Shield Advanced is an optional paid service. AWS Shield Advanced provides additional protections against more sophisticated and larger attacks for your applications running on Amazon Elastic Compute Cloud (EC2), Elastic Load Balancing (ELB), Amazon CloudFront, AWS Global Accelerator, and Route 53.

Your origin servers can be Amazon Simple Storage Service (S3), Amazon EC2, Elastic Load Balancing, or a custom server outside of AWS. You can also enable AWS Shield Advanced directly on Elastic Load Balancing or Amazon EC2 in the following AWS Regions - Northern Virginia, Ohio, Oregon, Northern California, Montreal, São Paulo, Ireland, Frankfurt, London, Paris, Stockholm, Singapore, Tokyo, Sydney, Seoul, Mumbai, Milan, and Cape Town. My answer is B

You CAN enable Shield Advanced directly on EC2. You CAN also expose EC2 instances directly to the Internet. But in this case, what is exposed to the Internet (= where DDoS attacks could land) is the Global Accelerator, not your EC2 instances.
