PREGUNTA

LAS OPCIONES CORRECTAS SON:

A user is creating a new EBS volume from an existing snapshot.

The snapshot size shows 10 GB.

Can the user create a volume of 30 GB from that snapshot?

A user can always create a new EBS volume of a higher size than the original snapshot size. The user cannot create a volume of a lower size. When the new volume is created the size in the instance will be shown as the original size. The user needs to change the size of the device with resize2fs or other OS specific commands. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-expand-volume.html

Can you SSH to your private machines that reside in a VPC from outside without elastic IP?

The instances that reside in the private subnets of your VPC are not reachable from the Internet, meaning that is not possible to ssh into them. To interact with them you can use a bastion server, located in a public subnet, that will act as a proxy for them. You can also connect if you have direct connect or vpn. http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Scenario2.html

PREGUNTA

LAS OPCIONES CORRECTAS SON:

Adeployment package uses the AWS CLIto copy files into any S3 bucket in the account, using access keys stored in environment variables.

The package is running on EC2 instances, and the instances have been modified to run with an assumed IAMrole and a more restrictive policy that allows access to only one bucket.

After the change, the Developer logs into the host and still has the ability to write into all of the S3 buckets in that account.

What is the MOST likely cause of this situation?
