Which task is a customer’s responsibility, according to the AWS shared responsibility model?

Explanations:

Customers are responsible for managing the guest operating systems, which includes tasks like updates, security patches, and configurations. This falls under the customer’s responsibility in the AWS shared responsibility model as they have control over the software running on the cloud resources they provision.

Maintenance of the configuration of infrastructure devices is primarily the responsibility of AWS. Customers do not manage the underlying physical infrastructure; instead, they configure the services provided by AWS.

Management of the host operating systems and virtualization is AWS’s responsibility. Customers do not have access to the underlying host operating systems or the virtualization layer used by AWS.

Maintenance of the software that powers Availability Zones is the responsibility of AWS. Customers use the services provided in these zones but do not maintain or manage the software that supports them.
