Topic 1 Question 217
A company uses a load balancer to distribute traffic to Amazon EC2 instances in a single Availability Zone. The company is concerned about security and wants a solutions architect to re-architect the solution to meet the following requirements:

• Inbound requests must be filtered for common vulnerability attacks. • Rejected requests must be sent to a third-party auditing application. • All resources should be highly available.

Which solution meets these requirements?
- Configure a Multi-AZ Auto Scaling group using the application's AMI. Create an Application Load Balancer (ALB) and select the previously created Auto Scaling group as the target. Use Amazon Inspector to monitor traffic to the ALB and EC2 instances. Create a web ACL in WAF. Create an AWS WAF using the web ACL and ALB. Use an AWS Lambda function to frequently push the Amazon Inspector report to the third-party auditing application.
- Configure an Application Load Balancer (ALB) and add the EC2 instances as targets. Create a web ACL in WAF. Create an AWS WAF using the web ACL and ALB name and enable logging with Amazon CloudWatch Logs. Use an AWS Lambda function to frequently push the logs to the third-party auditing application.
- Configure an Application Load Balancer (ALB) along with a target group adding the EC2 instances as targets. Create an Amazon Kinesis Data Firehose with the destination of the third-party auditing application. Create a web ACL in WAF. Create an AWS WAF using the web ACL and ALB then enable logging by selecting the Kinesis Data Firehose as the destination. Subscribe to AWS Managed Rules in AWS Marketplace, choosing the WAF as the subscriber.

- 正解だと思う選択肢: D
  Only A and D cover the requirement for high availability. A uses Inspector, which is a vulnerability scanner and does not monitor traffic. So - even that I don't like the complexity of D - this remains the only option

  I got with D. The reason to go with D is because other options ABC are wrong.
  
  It says use Amazon Inspector to inspect traffic to ALB. This is wrong. Amazon inspector does NOT inspect traffic coming to an Application Load Balancer (ALB). Amazon Inspector is a security assessment service that helps you analyze the security and compliance of your EC2 instances and applications running on them. To inspect traffic coming to an ALB, you can consider using other services such as AWS WAF (Web Application Firewall) or AWS Shield. AWS WAF allows you to define rules to filter and block malicious traffic targeting your ALB. B - Does NOT talk about HA as it is asked in ques C - Does NOT talk about HA as it is asked in ques
