Câu 19: AWS Certified Security - Specialty SCS-C03(New)

A company uses Amazon EC2 instances to host frontend services behind an Application Load Balancer. Amazon Elastic Block Store (Amazon EBS) volumes are attached to the EC2 instances. The company uses Amazon S3 buckets to store large files for images and music. The company has implemented a security architecture on AWS to prevent, identify, and isolate potential ransomware attacks. The company now wants to further reduce risk. A security engineer must develop a disaster recovery solution that can recover to normal operations if an attacker bypasses preventive and detective controls. The solution must meet an RPO of 1 hour. Which solution will meet these requirements?

1. A. Use AWS Backup to create backups of the EC2 instances and S3 buckets every hour. Create AWS CloudFormation templates that replicate existing architecture components. Use AWS CodeCommit to store the CloudFormation templates alongside application configuration code. — đáp án hiện tại
2. B. Use AWS Backup to create backups of the EBS volumes and S3 objects every day. Use Amazon Security Lake to create a centralized data lake for AWS CloudTrail logs and VPC flow logs. Use the logs for automated response.
3. C. Use Amazon Security Lake to create a centralized data lake for AWS CloudTrail logs and VPC flow logs. Use the logs for automated response. Enable AWS Security Hub to establish a single location for recovery procedures. Create AWS CloudFormation templates that replicate existing architecture components. Use AWS CodeCommit to store the CloudFormation templates alongside application configuration code.
4. D. Create EBS snapshots every 4 hours. Enable Amazon GuardDuty Malware Protection. Create automation to immediately restore the most recent snapshot for any EC2 instances that produce an Execution:EC2/MaliciousFile finding in GuardDuty.
