Zorluk: KolayNetwork Topology Architectures

A network administrator is designing a network for a medium-sized office building. To reduce hardware costs and simplify maintenance while maintaining connectivity between access layer devices and external networks, the administrator decides to combine the responsibilities of the core layer and the distribution layer into a single set of switches. Which network topology architecture is being implemented in this enterprise design?

  1. Collapsed core architectureCevap
  2. B
    Three-tier campus architecture
  3. C
    Spine-leaf architecture
  4. D
    Type 1 hypervisor virtual fabric

Cevap

The collapsed core architecture is being implemented because it merges the distribution layer and core layer roles into a single pair of switches.
In a collapsed core network design (also known as a two-tier campus design), the distribution layer and core layer functionality are merged into a single tier of redundant switches. This provides routing, security policy enforcement, and high-speed campus backbone connectivity on the same hardware, reducing overall cost and complexity for smaller site footprints.

Adım Adım Çözüm

1
Analyze the requirements described in the scenario
The design merges core and distribution layer duties into one switch tier to save cost in a medium-sized campus.
Identifying key structural consolidations helps differentiate enterprise network models.
2
Match the requirement to the standard Cisco topology definitions
A 2-tier design where core and distribution layers are combined is specifically known as a collapsed core topology.
Collapsed core models reduce tier count while retaining access layer connections.
