AWS Certified Cloud Practitioner — Question 708

Which AWS service requires the customer to patch the guest operating system?

Answer options

• A. AWS Lambda
• B. Amazon OpenSearch Service
• C. Amazon EC2
• D. Amazon ElastiCache

Correct answer: C

Explanation

Amazon EC2 is an Infrastructure as a Service (IaaS) offering, meaning the customer retains full administrative control over the virtual instances and is responsible for patching the guest operating system. In contrast, AWS Lambda, Amazon OpenSearch Service, and Amazon ElastiCache are managed or serverless offerings where AWS automatically handles underlying infrastructure maintenance, including OS patching.
