Your company is looking at decreasing the amount of time it takes to build servers that are deployed as EC2 Instances. These Instances always have the same type of software installed as per the security standards. As an architect, what would you recommend to decrease the server build time?

Answer options:

A.Look at creating snapshots of EBS Volumes
B.Create the same master copy of the EBS volume
C.Create a custom AMI
D.Create a base profile

Answer – C
The AWS Documentation mentions the following.
An Amazon Machine Image (AMI) provides the information required to launch an instance, which is a virtual server in the cloud. You must specify a source AMI when you launch an instance. You can launch multiple instances from a single AMI when you need multiple instances with the same configuration. You can use different AMIs to launch instances when you need instances with different configurations.
You can launch an instance from an existing AMI, customize the instance, and then save this updated configuration as a custom AMI. Instances launched from this new custom AMI include the customizations that you made when you created the AMI.
Options A and B are incorrect since they cannot create a master copy of the instance.
Option D is incorrect because creating a profile will not assist.
