Difficulty: HardNetwork Types and Topologies

A network architect is designing an infrastructure update for a regional bank. The project requires two main implementations: first, connecting six regional branch offices across the city such that every office has a dedicated direct connection to every other office for maximum fault tolerance; second, deploying a high-speed dedicated block-level storage network inside the main data center using Fibre Channel. Which of the following network topology and network classification combinations correctly fulfills these design requirements?

  1. Full mesh topology for the branch offices, and a SAN (Storage Area Network) for the data center storage infrastructureAnswer
  2. B
    Star topology for the branch offices, and a LAN (Local Area Network) for the data center storage infrastructure
  3. C
    Bus topology for the branch offices, and a MAN (Metropolitan Area Network) for the data center storage infrastructure
  4. D
    Ring topology for the branch offices, and a PAN (Personal Area Network) for the data center storage infrastructure

Answer

Full mesh topology for the branch offices, and a SAN (Storage Area Network) for the data center storage infrastructure
A full mesh topology connects every branch directly to every other branch, satisfying the requirement for complete multi-path redundancy. A SAN (Storage Area Network) provides dedicated block-level data storage access over high-speed protocols such as Fibre Channel, distinct from standard LAN/MAN networking.

Step-by-Step Solution

1
Analyze the branch office topology requirement.
The requirement states that all six branch offices must have direct connections to every other office for maximum fault tolerance.
A full mesh topology connects every node directly to every other node using n(n−1)2\frac{n(n-1)}{2} links, providing maximum redundancy without relying on a central intermediary.
2
Analyze the data center storage infrastructure requirement.
The storage system requires dedicated high-speed block-level data access using Fibre Channel.
A Storage Area Network (SAN) is a specialized high-speed network specifically designed to transfer block-level data between servers and storage arrays.
3
Synthesize the requirements to identify the matching pair.
Full mesh topology combined with a SAN (Storage Area Network).
Combining full mesh redundancy across sites with SAN technology in the data center satisfies both operational criteria.
