Question 6

What is the scope of an EBS volume?

A. VPC
B. Region
C. Placement Group
D. Availability Zone

Correct Answer:D
An Amazon EBS volume is tied to its Availability Zone and can be attached only to instances in the same Availability Zone.

Question 7

What is true of the way that encryption works with EBS?

A. Snapshotting an encrypted volume makes an encrypted snapshot; restoring an encrypted snapshot creates an encrypted volume when specified / requested.
B. Snapshotting an encrypted volume makes an encrypted snapshot when specified / requested; restoring an encrypted snapshot creates an encrypted volume when specified / requested.
C. Snapshotting an encrypted volume makes an encrypted snapshot; restoring an encrypted snapshot always creates an encrypted volume.
D. Snapshotting an encrypted volume makes an encrypted snapshot when specified / requested; restoring an encrypted snapshot always creates an encrypted volume.

Correct Answer:C
Snapshots that are taken from encrypted volumes are automatically encrypted. Volumes that are created from encrypted snapshots are also automatically encrypted. Your encrypted volumes and any associated snapshots always remain protected. For more information, see Amazon EBS Encryption.

Question 8

Your system automatically provisions EIPs to EC2 instances in a VPC on boot. The system provisions the whole VPC and stack at once. You have two of them per VPC. On your new AWS account, your attempt to create a Development environment failed, after successfully creating Staging and Production environments in the same region. What happened?

A. You didn't choose the Development version of the AMI you are using.
B. You didn't set the Development flag to true when deploying EC2 instances.
C. You hit the soft limit of 5 EIPs per region and requested a 6th.
D. You hit the soft limit of 2 VPCs per region and requested a 3r

Correct Answer:C
There is a soft limit of 5 E|Ps per Region for VPC on new accounts. The third environment could not allocate the 6th EIP.

Question 9

You are building out a layer in a software stack on AWS that needs to be able to scale out to react to increased demand as fast as possible. You are running the code on EC2 instances in an Auto Scaling Group behind an ELB. Which application code deployment method should you use?

A. SSH into new instances that come online, and deploy new code onto the system by pulling it from an S3 bucket, which is populated by code that you refresh from source control on new pushes.
B. Bake an AMI when deploying new versions of code, and use that AMI for the Auto Scaling Launch Configuration.
C. Create a Dockerfile when preparing to deploy a new version to production and publish it to S3. Use UserData in the Auto Scaling Launch configuration to pull down the Dockerfile from S3 and run it when new instances launch.
D. Create a new Auto Scaling Launch Configuration with UserData scripts configured to pull the latest code at all times.

Correct Answer:B
the bootstrapping process can be slower if you have a complex application or multiple applications to install. Managing a fileet of applications with several build tools and dependencies can be a challenging task during rollouts. Furthermore, your deployment service should be designed to do faster rollouts to take advantage of Auto Scaling.
