Exam question from Amazon's AWS-SysOps
Question #: 248
Topic #: 1
[All AWS-SysOps Questions]

A user has launched an EC2 instance store backed instance in the US-East-1a zone. The user created AMI #1 and copied it to the Europe region. After that, the user made a few updates to the application running in the US-East-1a zone. The user makes an AMI#2 after the changes. If the user launches a new instance in
Europe from the AMI #1 copy, which of the below mentioned statements is true?

  • A. The new instance will have the changes made after the AMI copy as AWS just copies the reference of the original AMI during the copying. Thus, the copied AMI will have all the updated data
  • B. The new instance will have the changes made after the AMI copy since AWS keeps updating the AMI
  • C. It is not possible to copy the instance store backed AMI from one region to another
  • D. The new instance in the EU region will not have the changes made after the AMI copy

Suggested Answer: D 🗳️
Within EC2, when the user copies an AMI, the new AMI is fully independent of the source AMI; there is no link to the original (source. AMI. The user can modify the source AMI without affecting the new AMI and vice a versa. Therefore, in this case even if the source AMI is modified, the copied AMI of the EU region will not have the changes. Thus, after copy the user needs to copy the new source AMI to the destination region to get those changes.

Selected Answer: D
In this scenario, the user created AMI #1 from the instance in the US-East-1a zone and then copied it to the Europe region. However, any changes made to the original instance after the creation of AMI #1 will not be reflected in the copied AMI #1.
