Answer: Capacity planning, TCO calculations, opex/capex allocation

Based on the community discussion and analysis of the question, option B is the correct answer. The consensus from the discussion (92% community support, high upvotes on comments supporting B) indicates that capacity planning, TCO calculations, and opex/capex allocation are the processes that undergo significant transformation when adopting Google Cloud Platform. Capacity planning shifts from physical hardware provisioning to cloud resource scaling, TCO calculations change due to the shift from capital investments to service-based consumption models, and opex/capex allocation is fundamentally altered as expenses move from upfront capital expenditures to ongoing operational costs. Option A is less suitable because LAN changes are more about implementation than process transformation, and the community notes that change management processes don't necessarily change significantly. Option C is incorrect because utilization measurement remains similar (often using the same tools), and data center expansion becomes irrelevant in cloud adoption. Option D is also incorrect for similar reasons - data center expansion is handled by the cloud provider, and utilization measurement doesn't undergo significant process change.
