Permit-plan conversion Lambdas and Fargate tasks in the planning account must concurrently read and write intermediate CAD-derived files that exceed /tmp and must be visible to the next step. Which shared storage should architects attach?
Select an answer to reveal the explanation.
Short Explanation
When many workers need the same scratch folder at once, that's a shared kitchen counter, not a drawer on one desk. EFS mounts on Lambda and Fargate so files are visible to the next step. EBS on one function and Glacier are not a concurrent scratch disk.
Full Explanation
Amazon EFS is the appropriate shared POSIX filesystem for Lambda and container tasks that need concurrent file access beyond /tmp. EBS attaches to a single instance, Glacier is archival object storage, and SSHFS to a bastion is not a managed modern architecture. EFS integrates with Lambda and Fargate for this exact scratch pattern.
