Answer: V – V – V.
## Explanation Let's analyze each statement: **First statement:** "Even if a given architectural pattern offers a solution to the problem being solved, it is not always adequate. Factors such as context and the system of forces that affect the solution are also part of the evaluation process and the choice of appropriate patterns." - **TRUE (V)**: This is correct. Architectural patterns must be evaluated in context, considering trade-offs, constraints, and forces that affect the solution. A pattern that solves a technical problem might not be suitable due to organizational, performance, or other contextual factors. **Second statement:** "MVC pattern is an adaptation of the Layers architectural pattern. The View Layer handles presentation and interface manipulation, the Model Layer organizes application-specific objects, and the Control Layer positions itself between these two with business rules." - **TRUE (V)**: This is correct. MVC (Model-View-Controller) is indeed an adaptation of the layered architecture pattern. The description accurately represents the responsibilities of each component: - **View**: Presentation layer - **Model**: Business logic and data - **Controller**: Mediates between View and Model **Third statement:** "The Broker pattern is aimed at problems in distributed environments. It suggests an architecture in which a component (broker) establishes mediation that allows decoupling between clients and servers." - **TRUE (V)**: This is correct. The Broker pattern is specifically designed for distributed systems where clients and servers need to communicate without direct coupling. The broker acts as an intermediary, handling communication, location transparency, and protocol translation. **Correct sequence:** V – V – V **Why other options are incorrect:** - **B) F – F – V**: Incorrect because all three statements are true - **C) V – V – F**: Incorrect because the third statement is true - **D) V – F – V**: Incorrect because the second statement is true - **E) F – V – F**: Incorrect because the first and third statements are true **Key architectural pattern concepts:** 1. **Context matters** in pattern selection 2. **MVC** is a layered architecture variant 3. **Broker pattern** addresses distributed system challenges

Analise as seguintes assertivas sobre padrões arquiteturais de software e assinale V, se verdadeiras, ou F, se falsas.
( ) Mesmo que um dado padrão arquitetural ofereça uma solução para o problema sendo resolvido, nem sempre ele é adequado. Fatores como contexto e o sistema de forças que afeta a solução fazem também parte do processo de avaliação e da escolha de padrões adequados.
( ) Padrão MVC é uma adaptação do padrão arquitetural Camadas. A Camada Visão lida com a apresentação e a manipulação da interface, a Camada Modelo organiza os objetos específicos da aplicação, e a Camada Controle posiciona-se entre estas duas com as regras do negócio.
( ) O padrão Broker é voltado a problemas de ambientes distribuídos. Sugere uma arquitetura na qual um componente (broker) estabelece uma mediação que permite um desacoplamento entre clientes e servidores.
A ordem correta de preenchimento dos parênteses, de cima para baixo, é:
A
V – V – V.
B
F – F – V.
C
V – V – F.
D
V – F – V.
E
F – V – F.
