1. The most likely reason your team member is unable to attach the EBS volume to an EC2 instance `in us-east-1b` is that EBS volumes are tied to a specific Availability Zone (AZ) upon creation. Since the volume was originally attached to an EC2 instance in us-east-1a, it is restricted to that AZ and cannot be directly attached to an instance `in us-east-1b`. us-east-1a์์์ EC2 ์ธ์คํด์ค๋ฅผ ์ข
