A user has created an ELB with the availability zone US-East-1A. The user wants to add more zones to ELB to achieve High Availability. How can the user add more zones to the existing ELB?
A.The user should stop the ELB and add zones and instances as required
B.The only option is to launch instances in different zones and add to ELB
C.It is not possible to add more zones to the existing ELB
D.The user can add zones on the fly from the AWS console
The user has created an Elastic Load Balancer with the availability zone and wants to add more zones to the existing ELB. The user can do so in two ways:
From the console or CLI, add new zones to ELB;
Launch instances in a separate AZ and add instances to the existing ELB. Reference:

B.The volume snapshot is saved in S3.
D.Data is deleted.
Any data on the instance store volumes persists as long as the instance is running, but this data

A user has launched a large EBS backed EC2 instance in the US-East-1a region. The user wants to achieve Disaster Recovery (DR) for that instance by creating another small instance in Europe. How can the user achieve DR?
A.Copy the instance from the US East region to the EU region
B.Use the “Launch more like this” option to copy the instance from one region to another
C.Copy the running instance using the “Instance Copy” command to the EU region
D.Create an AMI of the instance and copy the AMI to the EU region. Then launch the instance from the EU AMI
