Refer to the exhibit. An engineer must migrate the current topology to a topology that provides more speed, less latency, and support for software-define networks. The new topology has these requirements:
• separation into core, aggregation, and access routers
• varied server-to-server latency, depending on the path used
• support for extending the Layer 3 domain by combining access and aggregation routers

Which design topology meets these requirements?

A. flood-and-learn
B. three-tier
C. spine-and-leaf
D. core-edge

Selected Answer: C

The spine-leaf architecture is a simplified, two-layer data center network topology designed to address the limitations of the traditional three-tier architecture. The three-tier architecture uses distinct layers for access, aggregation, and core, while spine-leaf replaces these layers with a spine layer (core) and a leaf layer (access/aggregation). Spine-leaf offers improved performance, scalability, and redundancy for east-west traffic, which is traffic between servers within the data center.

I'll go with C here, although it has a "logical" separation of Core and access and has better low-latency performance than that of a 3tier
