Difficulty: HardNetwork Topologies and Types

Match each enterprise network deployment scenario to its corresponding network classification or topology architecture.

  • Connecting multiple geographically dispersed regional data centers across different metropolitan areas using software-defined overlay tunnels over public Internet transport.Software-Defined Wide Area Network (SD-WAN)
  • Interconnecting high-speed storage arrays and server clusters within a localized facility using Fiber Channel over Ethernet (FCoE) for block-level storage access.Storage Area Network (SAN)
  • Linking multiple corporate buildings owned by a single organization across a 5-mile contiguous corporate park over dedicated private fiber links.Campus Area Network (CAN)
  • Structuring a two-tier data center network fabric where every access/leaf switch connects directly to every aggregation/spine switch to ensure deterministic low latency for east-west traffic.Spine-and-Leaf Topology

Answer

The correct matches pair multi-region software-defined connectivity with SD-WAN, block-level storage consolidation with SAN, contiguous multi-building enterprise fiber links with CAN, and two-tier leaf-to-spine interconnects with Spine-and-Leaf topology.
Each scenario maps precisely to its classification: SD-WAN handles geographically separated sites over public internet overlays; SAN provides dedicated block-level storage transport; CAN links contiguous enterprise buildings on private land; and Spine-and-Leaf provides uniform latency across datacenter switches.

Step-by-Step Solution

1
Analyze the geographical boundary and transport ownership of each scenario.
Identify multi-metropolitan public transport connection as SD-WAN and contiguous private multi-building property as CAN.
Geographic extent and circuit ownership differentiate wide area overlay technologies from campus networks.
2
Evaluate data transport requirements and specialized protocol usage.
Classify localized block-level storage traffic utilizing FCoE as a Storage Area Network (SAN).
SANs isolate high-throughput storage traffic from standard local area network user data.
3
Examine non-blocking internal switch fabric interconnect structures.
Classify the two-tier architecture linking all leaf switches to all spine switches as Spine-and-Leaf topology.
Spine-and-Leaf replaces traditional hierarchical trees to optimize east-west datacenter throughput.

Key Concept

Categorizing network types by geographic scope, storage separation, and logical datacenter topology patterns.
