Question #1032
A company is migrating its video editing platform to AWS. The on-premises servers connect via an AWS Site-to-Site VPN connection. The video assets are updated frequently by multiple editors and are served from a network-attached storage (NAS) device. The company needs to migrate the platform without interrupting the editing process. They have deployed Amazon EC2 instances across multiple Availability Zones behind an Application Load Balancer. The company also needs to transfer 500 TB of archived footage to Amazon S3 as quickly as possible. Which combination of steps will meet these requirements? (Choose two.)
Set up a daily cron job using Amazon EventBridge to trigger an AWS Lambda function that synchronizes the EC2 instances with the NAS.
Configure an Amazon EBS Multi-Attach volume for the EC2 instances to share. Write code to synchronize the volume with the NAS weekly.
Mount an Amazon EFS file system to the on-premises servers and the EC2 instances. Copy the video assets to the EFS file system and serve content from it.
Order AWS Snowball Edge Storage Optimized devices. Copy the archived footage to the devices and ship them to AWS.
Use AWS DataSync to transfer the archived footage over the VPN connection to Amazon S3.
Explanation
Option C is correct because Amazon EFS allows the on-premises servers and EC2 instances to access the same file system simultaneously, ensuring continuity during migration. EFS scales automatically and integrates with both on-premises (via VPN/Direct Connect) and cloud environments. Option D is correct because AWS Snowball Edge Storage Optimized devices are designed for large-scale data transfers (like 500 TB), avoiding slow VPN transfers.
Option A is incorrect because Lambda cannot directly access on-premises NAS without a VPC setup, and daily syncs may not handle frequent updates. Option B is invalid since EBS Multi-Attach volumes only work within a single Availability Zone. Option E is suboptimal for 500 TB transfer over VPN due to bandwidth limitations, making Snowball the faster choice.
Answer
The correct answer is: CD
