Which of the following is a key characteristic of the Waterfall methodology?

Requirements are allowed to evolve throughout the project based on feedback

Requirements are gathered and fully documented before design begins

Development and testing occur simultaneously in the same phase

The project team delivers working increments at the end of each sprint

A manufacturing company has just completed a major network upgrade using a Waterfall approach. The project is now in the post-implementation review phase. What is the primary focus of this phase?

Documenting the design for the first time, since it was not done earlier.

Collecting continuous feedback from users to make immediate changes to the network.

Evaluating the network's performance against the original requirements and identifying optimization opportunities.

Starting the next phase of the project immediately, without any review.

In Agile, how does the iterative sprint approach affect network implementation?

The entire network is implemented in one final release

Implementation is performed only after the design is completely frozen

Implementation is delayed until all requirements are fully defined

Network components are implemented in small, frequent releases

How does Agile's continuous improvement cycle enable ongoing network optimization?

Optimization is deferred until the end of the project

Optimization is performed only after the entire network is deployed

Optimization is not possible in Agile because of changing requirements

Optimization is performed in each sprint based on feedback and performance data

What is a common reason to use a hybrid Waterfall-Agile approach in network design?

To combine the stability of upfront planning with the flexibility of iterative development

To avoid documentation and formal reviews

To ensure that all phases are completed in parallel

To eliminate the need for customer involvement
