Which combination of actions should a solutions architect take to improve the performance and resilience of the website?
(Choose two.)
Move the website images into an Amazon S3 bucket that is mounted on every EC2 instance
Share the website images by using an NFS share from the primary EC2 instance. Mount this share on the other EC2 instances.
Move the website images onto an Amazon Elastic File System (Amazon EFS) file system that is mounted on every EC2 instance.
Create an Amazon Machine Image (AMI) from the existing EC2 instance. Use the AMI to provision new instances behind an Application Load Balancer as part of an Auto Scaling group. Configure the Auto Scaling group to maintain a minimum of two instances. Configure an accelerator in AWS Global Accelerator for the website
Create an Amazon Machine Image (AMI) from the existing EC2 instance. Use the AMI to provision new instances behind an Application Load Balancer as part of an Auto Scaling group. Configure the Auto Scaling group to maintain a minimum of two instances. Configure an Amazon CloudFront distribution for the website.
Explanations:
Moving website images into an Amazon S3 bucket is a good practice for scalability and performance, but mounting S3 directly to EC2 instances is not feasible without additional configuration like S3FS or custom solutions.
Sharing the website images via NFS from a single EC2 instance introduces a single point of failure and lacks scalability. It does not improve performance or resilience.
Using Amazon EFS allows multiple EC2 instances to access the same file system, improving scalability and resilience as EFS is managed, highly available, and supports NFS.
Using an Auto Scaling group with an Application Load Balancer improves scalability and availability of EC2 instances, but the configuration of an accelerator in AWS Global Accelerator does not directly enhance performance for web content.
Creating an Auto Scaling group with an Application Load Balancer enhances scalability and resilience. Using Amazon CloudFront improves performance by caching content at edge locations globally.
