  1. Installing security patches on the guest operating systemCevap

    Maintaining the physical power generators in the AWS data centers

  4. D
    Upgrading the firmware on the physical host virtualization servers

Cevap

Installing security patches on the guest operating system
Under the AWS Shared Responsibility Model, the customer is responsible for 'security in the cloud'. For Amazon EC2 (an Infrastructure as a Service offering), this includes configuration, updates, and security patching of the guest operating system. The correct option correctly identifies guest operating system patching as the customer's responsibility.

Adım Adım Çözüm

1
Determine the service category for Amazon EC2
Amazon EC2 is classified as an Infrastructure as a Service (IaaS) offering.
IaaS services require the customer to perform administrative and configuration tasks starting from the operating system layer.
2
Distinguish between 'security in the cloud' and 'security of the cloud'
Guest operating system maintenance belongs to the customer ('security in the cloud'), whereas physical, hardware, and virtualization infrastructure security belongs to AWS ('security of the cloud').
This allocation defines the boundaries of the Shared Responsibility Model.
