Learn about the AWS Shared Responsibility Model and understand customer responsibilities, such as managing guest operating systems, for the AWS Certified Cloud Practitioner CLF-C02 exam.
In the AWS Shared Responsibility Model, responsibilities are divided between AWS and its customers. AWS ensures the security of the cloud infrastructure, including hardware, software, networking, and physical facilities. Customers, on the other hand, are responsible for security in the cloud, which includes managing their data, applications, and configurations.
Question
Which task is a customer responsibility according to the AWS Shared Responsibility Model?
A. Managing guest operating systems
B. Maintaining infrastructure devices configuration
C. Managing host operating systems and virtualization
D. Maintaining software that powers Availability Zones
Answer
A. Managing guest operating systems
Explanation
Managing guest operating systems is a customer responsibility, according to the AWS Shared Responsibility Model. The AWS Shared Responsibility Model defines the different security and compliance responsibilities of AWS and the customer. AWS is responsible for the security of the cloud, which includes the physical infrastructure, hardware, software, and facilities that run the AWS Cloud. The customer is responsible for security in the cloud, which includes configuring and managing guest operating systems, applications, data, and network traffic protection.
Why This Is Correct
Customers are responsible for managing the guest operating systems (OS), which includes:
- Installing updates and patches.
- Configuring security settings.
- Monitoring and maintaining OS performance.
This responsibility applies when using services like Amazon EC2 (Infrastructure as a Service), where customers have control over virtual machines and their operating systems.
Why Other Options Are Incorrect
B. Maintaining infrastructure devices configuration: AWS handles all infrastructure-related configurations, including physical devices like servers and networking equipment.
C. Managing host operating systems and virtualization: AWS manages the host OS and virtualization layer as part of its responsibility for securing the cloud infrastructure.
D. Maintaining software that powers Availability Zones: AWS ensures the maintenance and operation of software that supports its global infrastructure, including Availability Zones.
Understanding these distinctions is crucial for passing the AWS Certified Cloud Practitioner CLF-C02 exam, as it emphasizes recognizing customer versus AWS responsibilities within this model.
