Topic 1 Question 461
A company needs to migrate its website from an on-premises data center to AWS. The website consists of a load balancer, a content management system (CMS) that runs on a Linux operating system, and a MySQL database.
The CMS requires persistent NFS-compatible storage for a file system. The new solution on AWS must be able to scale from 2 Amazon EC2 instances to 30 EC2 instances in response to unpredictable traffic increases. The new solution also must require no changes to the website and must prevent data loss.
Which solution will meet these requirements?
Create an Amazon Elastic File System (Amazon EFS) file system. Deploy the CMS to AWS Elastic Beanstalk with an Application Load Balancer and an Auto Scaling group. Use .ebextensions to mount the EFS file system to the EC2 instances. Create an Amazon Aurora MySQL database that is separate from the Elastic Beanstalk environment.
Create an Amazon Elastic Block Store (Amazon EBS) Multi-Attach volume. Deploy the CMS to AWS Elastic Beanstalk with a Network Load Balancer and an Auto Scaling group. Use .ebextensions to mount the EBS volume to the EC2 instances. Create an Amazon RDS for MySQL database in the Elastic Beanstalk environment.
Create an Amazon Elastic File System (Amazon EFS) file system. Create a launch template and an Auto Scaling group to launch EC2 instances to support the CMS. Create a Network Load Balancer to distribute traffic. Create an Amazon Aurora MySQL database. Use an EC2 Auto Scaling scale-in lifecycle hook to mount the EFS file system to the EC2 instances.
Create an Amazon Elastic Block Store (Amazon EBS) Multi-Attach volume. Create a launch template and an Auto Scaling group to launch EC2 instances to support the CMS. Create an Application Load Balancer to distribute traffic. Create an Amazon ElastiCache for Redis cluster to support the MySQL database. Use EC2 user data to attach the EBS volume to the EC2 instances.

C is wrong because lifehook cannot mount EFS

A EBS is out first. For C, the NLB is weired but couldn't say its wrong. The scale-in policy to mount EFS is wrong, since mounting task should happens during scale-out process.
👍 3pangchn2024/03/25 A because I think Network Load Balancer is not the answer for this case
