Show answer and explanation
Correct answers: A, B, E
Explanation
The shared responsibility model shifts based on the type of service used. With services like Amazon EC2, customers have more control and therefore more responsibilities, such as managing the operating system and security. With fully managed services like AWS Lambda and Amazon RDS, AWS takes on more responsibilities, such as managing infrastructure, scaling, and backups. Understanding these shifts is key to effectively using AWS services.
- A. Correct.
Correct: With Amazon EC2, you are responsible for managing the operating system, including patching and securing it, as EC2 operates under the Infrastructure-as-a-Service (IaaS) model.
- B. Correct.
Correct: With AWS Lambda, AWS manages the underlying infrastructure and operating system, as Lambda is a serverless computing service.
- C. Incorrect.
Incorrect: With Amazon RDS, AWS handles database backups and patching, as these are managed services features.
- D. Incorrect.
Incorrect: With AWS Lambda, AWS automatically scales the infrastructure to meet demand, so customers do not need to manage scaling.
- E. Correct.
Correct: With Amazon RDS, AWS handles the underlying database software maintenance and backups, as RDS is a managed service.
