Which of the following types of network segmentation is an easy approach to divide a network but can be expensive as it occupies more space?

Question

Options

• AVLAN segmentation
• BLogical segmentation
• CNetwork virtualization
• DPhysical segmentation

• A
  2% (1)
• B
  2% (1)
• D
  95% (40)

Explanation

Physical segmentation divides a network by using separate, dedicated physical hardware - distinct switches, routers, cables, and infrastructure for each segment - making it the simplest conceptual approach but costly in equipment, cabling, rack space, and maintenance overhead.

Why the distractors are wrong:

• A (VLAN segmentation) is a logical method that partitions a network using software/configuration on shared hardware - space-efficient and cost-effective.
• B (Logical segmentation) is a broad category that includes VLANs and ACLs; it achieves separation through software rules, not physical hardware.
• C (Network virtualization) abstracts the entire network into software-defined layers, sharing physical resources across multiple virtual networks - the opposite of space-intensive.

Memory tip: Think Physical = Physical stuff - more switches, more cables, more racks, more money. The word "expensive" and "occupies more space" are direct clues pointing to real, tangible hardware. If a question mentions floor space or hardware cost as a drawback of segmentation, always think Physical first.
