Correct Answer: A
An NDB Software Profile is a template of the OS and database engine that you can use to provision or clone database server VMs using NDB. To create a software profile, you need to upload an installer package for the database software that you want to use, such as SQL Server or Oracle. The installer package must be compatible with the OS image that you have registered with Prism Element. You do not need a database server VM registered with NDB, a patch file for the installed databases, or an OS image registered with Prism Element to create a software profile. Those are required for other tasks, such as creating a software profile version, registering a database server VM, or provisioning a database server VM.
