In which way does a spine-and-leaf architecture allow for scalability (CCNA 200-301)
In which way does a spine-and-leaf architecture allow for scalability in a network when additional access ports are required?
A) A spine switch and a leaf switch can be added with redundant connections between them.
B) A spine switch can be added with at least 40 GB uplinks.
C) A leaf switch can be added with connections to every spine switch.
D) A leaf switch can be added with a single connection to a core spine switch.
Solution
Correct answer: C) A leaf switch can be added with connections to every spine switch.
In a spine-and-leaf architecture, scalability is achieved by adding leaf switches as the network grows. Each leaf switch is connected to every spine switch, creating a non-blocking fabric. This approach ensures that as new access ports are required, additional leaf switches can be added to the network, and the connections to every spine switch provide optimal bandwidth and redundancy. This design minimizes the risk of bottlenecks and allows for efficient scalability in large networks.
