Which option is a customer responsibility under the AWS shared responsibility model?

Explanations:

The maintenance of underlying hardware of Amazon EC2 instances is the responsibility of AWS, not the customer. AWS manages the physical infrastructure, including servers and networking.

Application data security is the customer’s responsibility. This includes securing data at rest and in transit, managing access controls, and ensuring proper encryption practices.

Physical security of data centers is the responsibility of AWS. AWS is responsible for the security of the physical facilities that house its infrastructure, including access controls and monitoring.

Maintenance of VPC components, such as subnets, route tables, and security groups, is the customer’s responsibility, but this option is misleading as it doesn’t pertain to the core customer responsibility in the shared responsibility model context.
