5. A small company has been using a public cloud IaaS provider for several months. During this time the company has seen significant growth in revenue. This growth has triggered a surge in hiring, which has forced the company to repeatedly purchase additional services at premium cost from their CSP.
The company has leased a data center and started designing a cloud infrastructure to deploy a private cloud environment. The underlying hypervisor technology they chose is different than that of the CSP. Once the initial infrastructure has been implemented, they will transition to a hybrid cloud model. New services will only be deployed in the private cloud.
A new CIO has just been hired, but has little experience with cloud computing. You are a Cloud Architect who has been asked to consult on several areas of concern.
The first service must be deployed in the private cloud within the next month. The CIO does not want to rely solely on the existing single sign-on solution hosted in the public cloud, because network disruption between the clouds would impact user access.

A) SAML
B) Public Key Infrastructure
C) OAuth
D) Identity Provider
