ISC2 Systems Security Certified Practitioner (SSCP) Practice Question
When designing a campus LAN expected to expand from four to eight departments over the next three years, the architect proposes a tree (hierarchical) topology that links multiple star-wired floors to core switches. Which primary advantage of this topology justifies the recommendation over a single flat star design?
It removes the need for any routing or segmentation devices because all nodes share a single broadcast domain.
It simplifies scalability, allowing new star segments to be added without redesigning the entire network.
It minimizes cabling costs by using one shared backbone cable for every device on the network.
It provides full path redundancy by default, eliminating single points of failure across all layers.
A tree, or hierarchical, topology organizes network devices into layers (core, distribution, access). Additional switches or entire star-based segments can be attached at the access or distribution layers with minimal disruption to existing links, making the network easy to scale and administer as the organization grows. While redundancy can be added, a basic tree still has potential single points of failure at higher layers, so it does not inherently guarantee fault tolerance. Likewise, routers may still be required for inter-VLAN or inter-subnet routing, and the cabling demand is greater than a simple bus. Its chief benefit in this scenario is straightforward, modular expansion and simplified management.
