Exam AWS Certified Cloud Practitioner topic 1 question 173 discussion

Who writes these questions lol. There's unnecessary levels of imprecision and ambiguity.

I thought it should be AD because RDS is also patched based on customer's recomendation. Maintenance windows in RDS is set by customer and he can agree whether major versions should be applied. Then I noticed that question states clearly: "operating system patch". For RDS, we manage patching ONLY for DATABASE engine (minor, major versions). So the correct answer is AE as we patch ECS by replacing AMI with newer version.

✅ Correct Answers: A. Amazon EC2 instances → You are responsible for installing OS updates and security patches. E. Amazon ECS instances (on EC2) → If your ECS containers run on EC2, you must patch the underlying EC2 OS. ❌ Incorrect Answers: B. AWS Lambda functions → AWS automatically manages the OS, so you don’t need to patch anything. C. AWS Fargate tasks → Fargate is serverless; AWS handles all infrastructure, including OS patching. D. Amazon RDS instances → AWS takes care of OS patching for RDS; customers only manage database updates.

B. AWS Lambda functions → No OS to patch (serverless, fully managed by AWS). C. AWS Fargate tasks → Serverless containers (AWS manages the underlying OS). E. Amazon ECS instances → If using EC2 launch type, then yes (but Fargate is serverless). Since the question doesn’t specify, Fargate is excluded.

AD should be the correct answer.

I think the correct answer is A & D

A AND D

A and E are the correct answer

A. Amazon EC2 instances D. Amazon RDS instances Both Amazon EC2 instances and Amazon RDS instances require regular patching of the underlying operating system. These instances provide virtual servers (EC2) and managed databases (RDS) where the operating system needs to be maintained and kept up-to-date to address security vulnerabilities and ensure optimal performance. Therefore, the company should include these resources in the document defining the operating system patch routine for all its systems.

A and E

A & E correct answer. ECS is not server less, so you need to provision and manage EC2 instances.

Occasionally, you may need to update the Amazon ECS container agent to pick up bug fixes and new features https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-agent-update.html

correct answer is AE

AE is right

I thought it should be AD because RDS is also patched based on customer's recomendation. Maintenance windows in RDS is set by customer and he can agree whether major versions should be applied.

Correct answer is AE as we patch ECS by replacing AMI with newer version.

The correct answer is (A) Amazon EC2 instances and (E) Amazon Elastic Container Service (Amazon ECS) instances. Amazon EC2 instances and Amazon ECS instances are both virtual machines that run on the AWS cloud. They can be used to run operating systems and applications. As such, they are both important resources that need to be included in the company's operating system patch routine document. AWS Lambda functions and AWS Fargate tasks are both serverless computing services. They do not run on virtual machines, but rather on AWS's infrastructure. As such, they are not directly involved in the operating system patch routine process. Amazon RDS instances are relational database services. They are not typically used to run operating systems or applications, so they do not need to be included in the company's operating system patch routine document.
