A small business is expanding and needs to ensure their network infrastructure supports growth. Which THREE practices should they implement?
⚠ Common exam trap
A common mix-up: candidates choose 'Use a single subnet for simplicity' thinking it reduces complexity, but it actually hinders scalability and introduces broadcast domain issues that degrade performance in a growing network.

Correct answer & explanation
✓
Deploy redundant power supplies for critical devices
Redundant power supplies ensure that critical network devices like switches and routers remain operational even if one power supply fails, minimizing downtime during business expansion. This practice directly supports network availability and growth by providing fault tolerance for essential infrastructure components.
Answer analysis
Option-by-option breakdown
