Difficulty: EasyNetwork Topology Architectures

A network technician is reviewing the physical and logical layout of a small branch office network that uses a 2-Tier (Collapsed Core) campus topology. Which two statements accurately describe key characteristics of this topology architecture? (Select TWO.)

  1. The core layer and distribution layer functions are combined into a single set of switches.Answer
  2. Access switches connect directly to the collapsed core/distribution devices.Answer
  3. C
    Access switches are used to isolate broadcast domains by default without requiring VLAN configurations.
  4. D
    Trunk links between the collapsed core switches must have PortFast enabled to ensure rapid convergence.

Answer

The two correct traits of a 2-Tier (Collapsed Core) campus topology are that core and distribution layer functions are combined into unified switches, and access switches connect directly to these collapsed core/distribution devices.
In a 2-Tier (Collapsed Core) architecture, the traditional core and distribution layers are combined into a single switch tier, allowing access switches to connect directly to the collapsed core. This minimizes cost and maintenance while providing essential Layer 2/Layer 3 redundancy and connectivity.

Step-by-Step Solution

1
Identify the defining structural characteristic of a 2-Tier campus architecture.
The core layer and distribution layer are merged (collapsed) into a single functional layer.
This reduces hardware cost, management overhead, and cabling complexity for smaller networks.
2
Determine how access layer devices connect within this architecture.
Access switches uplink directly into the collapsed core switches.
Since there is no standalone distribution tier, the access switches connect straight to the combined core/distribution layer.
