A user is planning to use EBS for his DB requirement. The user already has an EC2 instance running in the VPC private subnet. How can the user attach the EBS volume to a running instance?

The user can create EBS in the same zone as the subnet of instance and attach that EBS to instance.
It is not possible to attach an EBS to an instance running in VPC until the instance is stopped.
The user can specify the same subnet while creating EBS and then attach it to a running instance.
The user must create EBS within the same VPC and then attach it to a running instance.
