- A . CMP account with elevated privileges exists that can be shared with developers
- B . Mechanisms exist for changing the type of consumer resources automatically
- C . Mechanisms exist for re-installing CMP components for scaling
- D . Sufficient consumer resources exist to support the application elasticity
As a cloud architect designing a DIY PaaS Solution, you have concluded that using containers to support the target application is the best choice.
What consideration supports that decision?
- A . An application will run on multiple platforms with minor modification
- B . The abstraction of the physical hardware limits vulnerability
- C . Multiple operating systems can be supported in a single container
- D . The container supports the required software stack
