You are designing a multitenant SaaS solution and must choose a tenancy model. A colleague argues that switching between tenancy models after launch is trivial. Based on the guidance, which statement best describes the impact of the tenancy model choice?

A The tenancy model has no effect on application design or management and can be freely changed at any time.
B The tenancy model determines how each tenant's data is mapped to storage, affects application design and management, and switching later can be costly.
C The tenancy model only affects the application layer and never the data layer.
D The tenancy model exclusively controls the pricing model between the vendor and tenant.

A vendor wants strong tenant data isolation but is concerned about database cost across a large number of tenants. They are evaluating the standalone single-tenant app with single-tenant database model. Which trade-off should they expect?

A It provides the greatest database isolation but is the most expensive solution because elastic pools cannot be used across different resource groups or subscriptions.
B It provides weak isolation but is the cheapest solution because all tenants share one database.
C It provides moderate isolation and allows elastic pools to be shared across subscriptions to reduce cost.
D It provides no data isolation and requires a shared schema for all tenants.
