Question #26
Which tasks are the responsibility of AWS according to the AWS shared responsibility model? (Select TWO.)
- A . Configure AWS Identity and Access Management (IAM).
- B . Configure security groups on Amazon EC2 instances.
- C . Secure the access of physical AWS facilities.
- D . Patch applications that run on Amazon EC2 instances.
- E . Perform infrastructure patching and maintenance.
Correct Answer: C, E
C, E
Explanation:
The tasks that are the responsibility of AWS according to the AWS shared responsibility model are securing the access of physical AWS facilities and performing infrastructure patching and maintenance. The AWS shared responsibility model defines the division of responsibilities between AWS and the customer for security and compliance. AWS is responsible for the security of the cloud, which includes the physical security of the hardware, software, networking, and facilities that run the AWS services. AWS is also responsible for the maintenance and patching of the infrastructure that supports the AWS services. The customer is responsible for the security in the cloud, which includes the configuration and management of the AWS resources and applications that they use. Configuring AWS Identity and Access Management (IAM), configuring security groups on Amazon EC2 instances, and patching applications that run on Amazon EC2 instances are tasks that are the responsibility of the customer, not AWS.
