200-301 Question 52
Single answerAn organization is designing a data center network using the spine-leaf architecture. They need to ensure consistent low-latency communication between servers and scalability to handle growth. Which characteristic of the spine-leaf architecture directly supports these requirements?
- A
Every leaf switch connects to every spine switch, ensuring predictable latency.
- B
Spine-leaf uses a single-tier design that minimizes the number of switches.
- C
Spine switches act as default gateways for all connected devices.
- D
Leaf switches directly connect to each other to reduce traffic on the spine layer.
Show answer and explanation
Correct answer: A
Explanation
The spine-leaf architecture ensures that every leaf switch connects to every spine switch, providing consistent, high-speed, low-latency communication paths between all devices in the network. This design supports scalability and reduces bottlenecks by distributing traffic evenly across multiple paths.
- A. Correct.
This is correct. In a spine-leaf architecture, every leaf switch connects to every spine switch, creating predictable paths and consistent low-latency communication for east-west traffic across the data center.
- B. Incorrect.
This is incorrect. The spine-leaf architecture is a multi-tier design where scalability and performance benefits come from the separation of the spine and leaf layers.
- C. Incorrect.
This is incorrect. In a spine-leaf design, spine switches are not designed to act as default gateways but rather to provide high-speed interconnectivity between leaf switches.
- D. Incorrect.
This is incorrect. Leaf switches do not connect directly to each other in a spine-leaf architecture; they connect to the spine switches, which handle traffic between leaves.
