5. Refer to Scenario 1.
"
An IT department is offering 50 Service Offerings in their service catalog to meet all the application developers' needs. Many of the variants have a very small number of associated instantiations. A "big data" platform is offered and being actively utilized by a team of data scientists.
All services are sourced from within the private cloud. The developers are able to customize the platform's compute, storage, protection and network configuration upon instantiation. They can also provision additional resources after the initial instantiation through an upgrade service within the catalog. Because of the culture of the organization, no chargeback mechanism is implemented.
Within six months, IT experiences these problems:
(a). Developers are complaining of poor and inconsistent performance
(b). Resource utilization has far exceeded expectations
(c). The environment has become very complex
(d). Since the resource pools are shared throughout the organization, IT has been unable to identify usage patterns, making capacity planning very difficult"
What can the IT department do to resolve problem (c)?

A) Offload the "big data" IaaS platform to a public service provider
B) Implement a showback mechanism to influence consumer behavior when choosing specific resources
C) Provide separate resource pools for the application developers and the data scientists and manage the pools separately
D) Standardize on a subset of offerings to meet the needs of most developers and minimize the number of customization options
