Question:
What is a definition of a two-tier LAN network design?
- access and core layers collapsed into one tier, and the distribution layer on a separate tier
- distribution and core layers collapsed into one tier, and the access layer on a separate tier
- access, distribution, and core layers collapsed into one tier, with a separate backbone layer
- access and distribution layers collapsed into one tier, and the core layer on a separate tier
Explanation: Maintaining three separate network tiers is not always required or cost-efficient. All network designs require an access layer, but a two-tier design can collapse the distribution and core layers into one layer to serve the needs of a small location with few users.
