  D. AWS provides the infrastructure and services (like EC2) that include a range of Amazon Machine Images (AMIs) with pre-installed operating systems. This means AWS is responsible for ensuring that these AMIs are available and that the underlying infrastructure to run these instances is secure and reliable.

  The other responsibilities listed - database backups (A), database software patches (B), and operating system patches (C) - are under the purview of the customer when using Amazon EC2 instances.

• 正解だと思う選択肢: D

  A. Database backups - Customer responsibility. Customers are responsible for managing and maintaining backups of their data. AWS provides tools and services, but it's up to the customer to implement and manage backup strategies for their databases.

  B. Database software patches - Customer responsibility. The customer is responsible for applying patches and updates to the database software running on their EC2 instances. This includes managing the software lifecycle, updates, and security patches.

  C. Operating system patches - Customer responsibility. Similar to database software patches, the customer is responsible for applying patches and updates to the operating system of the EC2 instances. AWS manages the infrastructure, but the customer is responsible for the configuration and maintenance of their instance's operating systems.

  D. Operating system installations - AWS responsibility. AWS takes care of installing and maintaining the operating system on the EC2 instances. This is part of the underlying infrastructure managed by AWS as a cloud service provider.
