A startup is building a web app that handles sensitive customer transactions. It will use a web front end, a separate business logic layer, and an isolated database server. Which application architecture model best fits this design?
The three-tier application architecture model is the correct choice because it separates the user interface, business logic, and data storage layers. Each tier can be secured, scaled, and maintained independently, improving security, performance, and manageability. A one-tier model places all components together, creating a single point of failure and greater risk. A two-tier model gives the client direct database access, offering less isolation of business logic. An n-tier model is a broader category, but the scenario explicitly maps to three tiers, making three-tier the best answer.
