EBS Snapshots are backed up to S3 in what manner?

  • Incrementally

Do Amazon EBS volumes persist independently from the life of an Amazon EC2 instance, for example, if I terminated an EC2 instance, would that EBS volume remain?

  • Only if instructed to when created

Can I delete a snapshot of an EBS Volume that is used as the root device of a registered AMI?

  • No

A placement group can be deployed across multiple Availability Zones.

  • False

While creating the snapshots using the command line tools, which command should I be using?

  • ec2-create-snapshot

Can you attach an EBS volume to more than one EC2 instance at the same time?

  • No

A placement group is ideal for

  • EC2 instances that require high network throughput and low latency across a single availability zone.

Using the console, I can add a role to an EC2 instance, after that instance has been created and powered up.

  • False

I can change the permissions to a role, even if that role is already assigned to an existing EC2 instance, and these changes will take effect immediately.

  • Yes
