Which type of organization should use a collapsed-core architecture?
A collapsed-core architecture refers to a network design where the core and distribution layers of the network are combined into a single layer. This design is suitable for organizations with specific requirements and characteristics. Let's explore each answer choice to understand which type of organization should use this architecture.
A. Small and needs to reduce networking costs: A collapsed-core architecture is not the best choice for small organizations looking to reduce networking costs. It involves a more complex design that requires additional equipment, which may increase costs. A simpler network design would be more suitable for small organizations looking to save on networking costs.
B. Large and must minimize downtime when hardware fails: A collapsed-core architecture is also not ideal for large organizations that need to minimize downtime when hardware fails. Since the core and distribution layers are combined, any hardware failure will impact the entire network, causing more downtime. In such a scenario, a more redundant and fault-tolerant network design, such as a multi-layer architecture, would be a better choice.
C. Large and requires a flexible, scalable network design: A large organization requiring a flexible and scalable network design could benefit from a collapsed-core architecture. This design simplifies the network and reduces the number of layers, making it easier to manage and scale. The organization can easily add new switches to the existing layer without needing to add additional distribution or core layers. This design also allows for better bandwidth utilization since there are fewer network segments to traverse.
D. Currently small but is expected to grow dramatically in the near future: A collapsed-core architecture may be a good fit for a small organization that expects significant growth in the near future. This design can easily scale as the organization grows, and it simplifies network management. However, if the organization expects rapid growth and needs to minimize downtime, a multi-layer architecture may be a better choice.
In conclusion, the best answer is C, as a large organization requiring a flexible and scalable network design could benefit from a collapsed-core architecture.
