Answer: Seamless integration of EC2 with Amazon VPC, AWS CloudTrail, and AWS IAM., The flexible, pay-as-you-go pricing model of EC2.
The correct answers are B and D. Amazon EC2 instances offer seamless integration with Amazon VPC for network isolation, AWS CloudTrail for auditing API calls, and AWS IAM for managing access to AWS resources, which simplifies network configuration, monitoring, and security management. Additionally, EC2 provides a flexible, pay-as-you-go pricing model, allowing users to pay only for the compute capacity they use, without the need for upfront hardware investments. This model supports cost efficiency and scalability as application requirements change. Option A is incorrect because AWS does not manage the operating system or patching for EC2 instances; that responsibility lies with the user. Option C is incorrect as no AWS service guarantees 100% uptime; EC2's SLA is around 99.95% to 99.99%. Option E is also incorrect because EC2 does not offer automatic storage cost optimization; users are responsible for managing and optimizing their storage costs.
