Which task is the responsibility of AWS in this scenario?
Update the guest operating system of the EC2 instances.
Maintain high availability at the database layer.
Patch the physical infrastructure that hosts the EC2 instances.
Configure the security group firewall.
Explanations:
The customer is responsible for updating the guest OS on EC2 instances. AWS provides the infrastructure but not OS maintenance.
High availability at the database layer is a responsibility of the customer in an EC2 deployment, as AWS only provides the instance infrastructure.
AWS is responsible for patching and maintaining the physical infrastructure hosting EC2 instances, ensuring stability and security.
Security group configuration for firewall rules on EC2 instances is the customer’s responsibility, as it involves application-level setup.
My best guess is:
Patch the physical infrastructure that hosts the EC2 instances.
I infer that the answer is:
Patch the physical infrastructure that hosts the EC2 instances.
