What are some advantages of using Amazon EC2 instances to host applications in the AWS Cloud instead of on premises? (Choose two.)
Using Amazon EC2 instances to host applications in the AWS Cloud offers significant advantages over on-premises hosting. One key advantage is the seamless integration of EC2 with other AWS services such as Amazon VPC for networking, AWS CloudTrail for auditing and monitoring, and AWS IAM for access control and security. This integration enhances the overall functionality and security of the application infrastructure. Another advantage is the flexible, pay-as-you-go pricing model offered by EC2, which allows users to pay only for the resources they consume, thus eliminating the need for upfront infrastructure investment and enabling efficient cost management by scaling resources based on application demands.
I think it should be B and D. Based on https://www.amazonaws.cn/en/ec2/
B technically isn’t an advantage. You can implement Audit logging (Win Event Viewer etc.), Identity and Access Management on prem (Active Directory) and also on-prem networks are already behind a firewall protecting from public internet traffic which VPC offers but in the cloud. C and D are the right answers imo
C isn't true. The only AWS service with a 100% uptime SLA is route 53. EC2 is around 99.99% to 99.5%. https://aws.amazon.com/compute/sla/ I do think that native integrations between EC2 and the various AWS services like cloudtrail/VPC/IAM is an advantage over on-prem solutions which tend to be more piecemeal. While I agree that VPC and IAM there may be equivalent to on-prem solutions, you cannot track API calls on your on-prem like you would via CloudTrail. As for Option E of automatic cost optimization for storage cost. I do not believe that instance store scales up (vertical scaling) automatically. ASGs only spin up more instances of the same type. EBS does not scale and you pay for what is provisioned whether you use or not.
BD as EC2 doesn't have any storage cost optimization options, only S3 has: https://aws.amazon.com/s3/cost-optimization/
according to this.... EC2 does have optimized storage https://aws.amazon.com/ec2/instance-types/
I think 'storage optimized instance' is not meaning that can automatic optimize storage itself. 🤣
The advantages of using Amazon EC2 instances to host applications in the AWS Cloud instead of on-premises are: B. EC2 integrates with Amazon VPC, AWS CloudTrail, and AWS Identity and Access Management (IAM). D. EC2 has a flexible, pay-as-you-go pricing model. Explanation: A. EC2 does not include operating system patch management by default. This responsibility falls on the user to manage. C. EC2 does not have a 100% service level agreement (SLA). While AWS guarantees a certain level of availability for EC2 instances, it's not 100%. E. EC2 does not have automatic storage cost optimization. Users are responsible for managing and optimizing their storage resources.
B. EC2 integrates with Amazon VPC, AWS CloudTrail, and AWS Identity and Access Management (IAM): Amazon EC2 instances seamlessly integrate with various AWS services such as Amazon Virtual Private Cloud (VPC), AWS CloudTrail for auditing, and AWS IAM for identity and access management. This integration simplifies network configuration, monitoring, and security management. D. EC2 has a flexible, pay-as-you-go pricing model: Amazon EC2 offers a flexible pricing model that allows you to pay only for the compute capacity you actually use. This pay-as-you-go pricing model eliminates the need for upfront hardware investments and provides cost efficiency and scalability as your application's requirements change.
I thought A is valid as EC2 (unless it is a dedicated host) patch management is taken care of AWS
A is completely wrong answer. AWS never interfere in Customer's data, managing OS, patching.AWS is responsible for managing the underlying hardware.
https://aws.amazon.com/ec2/instance-types/ D. Pay-as-you-go. E. Storage optimized.
Storage optimized => YES BUT in question automatic storage COST optimization
EC2 doesn't have any storage cost optimization options, only S3 has.
B. EC2 integrates with Amazon VPC, AWS CloudTrail, and AWS Identity and Access Management (IAM): Amazon EC2 seamlessly integrates with other AWS services like Amazon VPC for networking, AWS CloudTrail for auditing and monitoring, and IAM for access control and security management. This integration enhances the overall functionality and security of the application infrastructure. D. EC2 has a flexible, pay-as-you-go pricing model: Amazon EC2 offers a flexible pricing model based on usage. Users can choose from a variety of instance types and sizes, paying only for the resources consumed on an hourly or per-second basis. This pay-as-you-go model eliminates the need for upfront infrastructure investment and allows for cost optimization by scaling resources up or down based on application demands.
I think answer B and D.
B&D are only correct answers.
BD are correct answers https://docs.aws.amazon.com/AmazonS3/latest/userguide/Welcome.html
Not E because you have to opt for this feature in EC2. and it is not about storage-optimized instance type
BD are the right choice
Agree. B&D
EC2 integrates with Amazon VPC, AWS CloudTrail, and AWS Identity and Access Management (IAM): Amazon VPC allows you to create a virtual network in the AWS Cloud that is isolated from the public internet. AWS CloudTrail records all AWS API calls made to your account, and AWS IAM allows you to control who has access to your AWS resources. These features can help you improve the security of your applications. EC2 has a flexible, pay-as-you-go pricing model: You only pay for the EC2 instances that you use, and you can scale your usage up or down as needed. This can help you save money on your AWS costs.
B and D is the right answer

BD is the correct answer!
