• 正解だと思う選択肢: C

  A is incorrect because when we set up an instance of ec2 we choose the operating system. B is incorrect because we are configuring and running the database on the ec2 instances so that would be our responsibility. D is incorrect because the firewall rules are our job. C is correct because the physical infrastructure where the ec2 instances run is amazon's responsibility

• 正解だと思う選択肢: C

  A. Update the guest operating system of the EC2 instances:

  Responsibility of the customer: Customers are responsible for managing the software environment within their EC2 instances, including updating the guest operating system.
  

  B. Maintain high availability at the database layer:

  Shared responsibility: While AWS ensures high availability at the infrastructure level, customers are responsible for configuring and managing the database layer to achieve high availability. This involves setting up replication, failover mechanisms, and ensuring that the database software is configured appropriately.
  

  C. Patch the physical infrastructure that hosts the EC2 instances:

  Responsibility of AWS: AWS manages the physical infrastructure, including patching and updates at the hardware level. Customers do not have direct control over the physical infrastructure.
  

  D. Configure the security group firewall:

  Responsibility of the customer: Security groups are a customer-managed feature that controls inbound and outbound traffic to and from EC2 instances. Customers are responsible for configuring security groups to meet their specific security requirements.
