Which of the following are customer responsibilities under the AWS shared responsibility model?

Explanations:

Physical security of AWS facilities is the responsibility of AWS, as it includes the security measures to protect data centers and hardware infrastructure.

Configuration of security groups is the customer’s responsibility, as customers must define their own access controls and network configurations in AWS.

Encryption of customer data on AWS is the responsibility of the customer, as they must implement encryption for their data at rest and in transit.

Management of AWS Lambda infrastructure is primarily AWS’s responsibility, as AWS manages the underlying infrastructure while customers manage their code.

Management of network throughput of each AWS Region is not a customer responsibility; AWS handles the infrastructure and ensures proper network performance.
