Question 6

An organization wants to provide IaaS capabilities in a hybrid cloud. They have the following requirements:
*
Each line of business must have access to its own services and templates
*
Service templates should be as generic as possible
*
Data encryption should be provided for only services that require it
*

*
Each instance should have the latest OS patches applied
*
Consumers should be given the ability to select which cloud to use for instance deployment
How can these requirements be addressed in a cloud design?

A. Configure multiple tenants and pools in the service catalogAdd a template to the service catalog for each tenantProvide orchestration workflows enabling instance creations, customization and placementProvide orchestration workflows enabling data encryption and authenticationEnable a configuration manager policy for OS updates B.
