Which factor is least typically considered in network capacity planning?

• A. Demand forecasting
• B. Uplink/port capacity
• C. Growth projections
• D. VLAN leakage risk

Answer: (D)

Capacity planning looks at how to size the network to handle traffic demand. You plan around forecasting expected usage to project loads, growth projections to anticipate future needs, and uplink/port capacity to ensure there are enough ports and enough bandwidth on switches and aggregation links. These factors directly determine when and where bottlenecks might occur and how to provision hardware to meet performance targets. VLAN leakage risk, by contrast, is about security and network segmentation—whether traffic can cross into unintended VLANs due to misconfigurations or VLAN hopping vulnerabilities. That concern affects isolation and security controls, not the amount of traffic the network must carry, so it’s not typically a factor in capacity planning.
