Exam N10-008 topic 1 question 456 discussion

A. Spine and Leaf Architecture The spine-leaf architecture consists of only two layers of switches spine and leaf switches. The spine layer consists of switches that perform routing and work as the core of the network. The leaf layer involves access switches that connect to servers, storage devices, and other end-users. This structure helps data center networks reduce hop count and reduce network latency.

In collapsed core architecture, the core and distribution layers are combined, simplifying the design. The three-tier model is necessary for complex campuses that require access by multiple sites, devices and users. It results in a network that is scalable, cost-efficient and reliable for large enterprises. However, smaller campuses can reap similar benefits with a simpler model, scaled down to improve costs and oversight. https://www.eiresystems.com/what-is-a-collapsed-core-network/#:~:text=In%20collapsed%20core%20architecture%2C%20the,and%20reliable%20for%20large%20enterprises.

In the collapsed core architecture, the core and distribution layers are combined into a single layer, which reduces the number of hops between devices and the associated latency. This architecture is often used in smaller networks where scalability and complexity are not significant concerns.

Another of those bad questions. Which text book did that guy read before setting this question? It is just a random choice. Spine and leaf I associate more with scalability and also predictable latency, reduces the number of hops Collapsed core is mainly for simplicity, and it also avoids the distribution switches. because I wrote that above and added latency keyword in spine and leaf, I will select spine and leaf. Looks like they open a random book and read a specific page and without any context set a question

If you look at ciscos new implementation of network management you will see that spine and leaf define what is being asked.

This is exactly what Spine and Leaf is for.

A. Spine and leaf architecture reduces network latency by enforcing a limit on the number of switching devices on the frame's path between any internal hosts.

A and D look similar in practice, but Spine and Leaf is explicitly set up to reduce the number of hops between clients and core switches. I would go for A then.

A is correct
