Exam AWS Certified Cloud Practitioner topic 1 question 164 discussion

When you choose to use EC2 for your database, you first have to provision the EC2 instance, which means you will use an AMI, containing the OS itself which is then installed by AWS to the EC2. All the other tasks are your responsibility.

Why there are so many confusing questions here?

I think the correct Answer is c as the EC2 is not fully managed service thats mean teh customer responsibilties are to Database backups , database software patches and operatiing system installation While the AWS responbility is operating system patchesbut applying them is the customer’s responsibility. However, AWS does automatically patch the underlying host system where the EC2 instance runs.

C. Operating system patches When a company hosts its databases on Amazon EC2 instances, AWS is responsible for the underlying hardware (such as the physical servers and data centers) and the hypervisor that runs the EC2 instances. However, the company is responsible for managing the software stack, including the operating system and database software.

Operating system patches: Customer responsible for guest OS AWS responsible for host OS

D cant be the answer, as then that would mean AWS is also responsible for patching the OS (C). Feels like A or none of the above

None Look at the table here ECS vs RDS. https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Welcome.html

https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Welcome.html Answer is E:, none of the above

C. Operating system patches: This is a shared responsibility. AWS is responsible for providing security updates and patches for the underlying infrastructure (the EC2 instances), while the company is responsible for applying operating system patches to the EC2 instances themselves.D. Operating system installations: This is primarily the responsibility of the company. While AWS provides the infrastructure (EC2 instances), it's up to the company to install and configure the operating system on those instances.So, the best correct answer is: A. Database backups

A. Database backups: This responsibility typically belongs to the company. While AWS provides tools and services to help with backups (e.g., Amazon RDS for managed database services), it's ultimately the company's responsibility to set up and manage backups for databases running on EC2 instances.B. Database software patches: This is generally the responsibility of the company. The company must manage and apply patches and updates to the database software running on EC2 instances.

D is not correct answer, Having AMI in Marketplace doesn't mean actual OS installations. Customer will have to choose the AMI,and launch it as Instance. So in this customer has full control over the OS,he can customize the AMI and launch it as per its requirement.

This is a tricky question, you can see all of the choices are customer responsibility based on the table here: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Welcome.html

D. Operating system installations.

When a company hosts its databases on Amazon EC2 instances, AWS is responsible for providing the underlying infrastructure and managing the physical hardware of the EC2 instances. However, the responsibility for tasks related to the software and data stored within the instances is typically the responsibility of the customer. Therefore, among the options provided, the responsibility that belongs to AWS when a company hosts its databases on Amazon EC2 instances is option D, operating system installations. AWS provisions and manages the underlying operating system for EC2 instances, ensuring that it is installed and ready for customer use.

A is correct

When a company hosts its databases on Amazon EC2 instances, AWS is responsible for providing and maintaining the underlying infrastructure, including the physical server, network, and storage resources. However, the responsibility for managing the databases, including database backups, database software patches, operating system patches, and operating system installations, is the responsibility of the customer. Therefore, the answer is none of the options (A, B, C, or D) belong to AWS responsibility.
