Question-28:A legacy system is a system, technology, or software programme that has been around for a long time but is still in use by an organisation because it can still carry out the tasks that it was designed to carry out in the first place. This might be considered an outdated system. Legacy systems, in general, do not get support or maintenance anymore, and their potential for expansion is severely constrained. Which of TerramEarth's legacy corporate processes are likely to undergo considerable transformation as a direct consequence of the company's growing usage of Google Cloud Platform?
A. Allocation of operating expenses and capital expenditures, LAN modifications, and capacity planning
B. Planning for capacity, calculating total cost of ownership, and allocating opex and capex
C. Planning for more capacity, determining how efficiently it is being used, and expanding the data centre
D. Expansion of the Data Center, Calculations of the TCO, and Utilization Measurement

: 2 Explanation: Capacity planning, TCO calculations, opex/capex allocation From the case study, it can conclude that Management (CXO) all concern rapid provision of resources (infrastructure) for growing as well as cost management, such as Cost optimization in Infrastructure, trade up front capital expenditures (Capex) for ongoing operating expenditures (Opex), and Total cost of ownership (TCO) Option-1 is not correct because LAN change management processes don't need to change significantly. TerramEarth can easily peer their on-premises LAN with their Google Cloud Platform VPCs, and as devices and subnets move to the cloud, the LAN team's implementation will change, but the change management process doesn't have to. Option-2 is correct because all of these tasks are big changes when moving to the cloud. Capacity planning for cloud is different than for on-premises data centers; TCO calculations are adjusted because TerramEarth is using services, not leasing/buying servers; OpEx/CapEx allocation is adjusted as services are consumed vs. using capital expenditures. Option-3 is not correct because measuring utilization can be done in the same way, often with the same tools (along with some new ones). Data center expansion is not a concern for cloud customers; it is part of the undifferentiated heavy lifting that is taken care of by the cloud provider. Option-4 is not correct because data center expansion is not a concern for cloud customers; it is part of the undifferentiated heavy lifting that is taken care of by the cloud provider. Measuring utilization can be done in the same way, often with the same tools (along with some new ones).
