Which task is the responsibility of AWS in this scenario?
Update the guest operating system of the EC2 instances.
Maintain high availability at the database layer.
Patch the physical infrastructure that hosts the EC2 instances.
Configure the security group firewall.
Explanations:
Updating the guest operating system is the responsibility of the customer, not AWS. Customers manage their EC2 instances, including OS updates.
While AWS provides infrastructure support, maintaining high availability at the database layer is primarily the customer’s responsibility, especially when managing a NoSQL database on EC2.
Patching the physical infrastructure is AWS’s responsibility. They manage the underlying hardware and ensure it is secure and up-to-date.
Configuring security group firewalls is the customer’s responsibility. Customers must set up and manage their security settings for their EC2 instances.
I believe the answer is:
Patch the physical infrastructure that hosts the EC2 instances.
