When should an engineer implement a collapsed-core architecture? (CCNA 200-301)

Correct answer: B. For small networks with minimal need for growth.
A collapsed-core architecture is a network design where the core and distribution layers are combined into a single layer, often on a single device. This design is suitable for small networks with minimal need for growth, as it simplifies the network design and reduces the number of devices required.

This design is not suitable for large networks or networks that require scalability, as it can become difficult to manage and maintain. It is also not suitable for networks that require high levels of redundancy and fault tolerance.

The other options are incorrect because:
A. VSS (Virtual Switching System) technology is a feature that allows multiple switches to be combined into a single logical switch, but it is not a requirement for implementing a collapsed-core architecture.
C. Large networks that are connected to multiple remote sites typically require a more complex network design, with separate core, distribution, and access layers, to provide scalability and redundancy.
D. The access and distribution layers do not necessarily need to be on the same device in a collapsed-core architecture, but rather the core and distribution layers are combined.
