You need to re-create an EBS volume that you have used previously. How might you go about doing that? A. Use a CloudFormation template to recreate the volume. B. Use the copy that lives in the Auto Scaling group. C. Re-create the volume from a snapshot. D. Copy the AMI the volume was based on and spin it up.

C. Re- create the volume from a snapshot Amazon EBS snapshots are stored incrementally. When you take a new snapshot, only the blocks that you changed after your last snapshot are saved. EBS snapshots can be copied across AWS regions ( using EBS snapshot Copy), thus making it easier for you to leverage multiple AWS regions and accelerate your geographical expansion, data center migration and disaster recovery. EBS snapshot Copy can be accessed via EC2 Command Line Interface or EC2 (API- application programming interface-software intermediary that allows two applications to talk to each other. Each time you use an app like Facebook, send an instant message, or check the weather on your phone, you're using an API.)

You have been asked to archive some data into Glacier that needs to be encrypted. What is the easiest way to achieve this? A. Glacier is not compatible with encrypted data, so it is the wrong choice for this - use S3 instead B. Once the data is in Glacier use the AWS Console to encrypt it. C. Send the data to Glacier and do nothing more - all data in Glacier is encrypted by default D. Encrypt the data locally on your server before sending it to Glacier

C. Send the data to Glacier and do nothing more- all data in Glacier is encrypted by default Data stored in Glacier is encrypted by default so nothing else needs to be done. Although you can encrypt your data before sending it to Glacier, unless you need the extra security this brings over using the inbuilt encryption this is not needed. Encrypting the data in-place once it is in Glacier is not possible so is not a valid option.

What happens when an RDS Master database in a Multi-AZ deployment goes down? A. You must use the AWS console to promote the standby to Master. B. You must copy the attached EBS volume to the standby. C. RDS automatically fails over to the standby, which is promoted to Master. D. The asynchronous replication of RDS Multi-AZ deployments means you will suffer some data loss.

C. RDS automatically fails over to the standby, which is promoted to Master. Amazon RDS automatically creates a primary DB Instance and synchronously replicates the data to a standby instance in a different Availability Zone (AZ). In case of an infrastructure failure, Amazon RDS performs an automatic failover to the standby (or to a read replica in the case of Amazon Aurora), so that you can resume database operations as soon as the failover is complete.
