In a VLAN network, which of the following descriptions about high-density network planning is wrong?

Question

Options

• ABefore calculating the number of APs, you need to inspect and check the venue structure in
• BHigh-density scenario is a coverage-limited scenario
• CHigh-density scenario is a capacity-limited scenario
• DIn high-density scenarios, there are many APs, and the distance between APs needs to be

• A
  6% (1)
• B
  17% (3)
• C
  72% (13)
• D
  6% (1)

Explanation

Note on the provided answer: There appears to be an error in this question - based on standard wireless networking principles, B is the wrong description, not C. Here's the full breakdown:

Why B is actually the wrong statement: High-density environments (stadiums, conference halls, auditoriums) are capacity-limited, not coverage-limited. The challenge is not reaching users with signal - APs are physically close to everyone - but rather serving massive numbers of simultaneous users without congestion or interference.

Why C is actually correct (not wrong): Saying "high-density is a capacity-limited scenario" is the accurate, textbook definition. Bandwidth exhaustion and channel interference, not signal distance, are the primary constraints.

Why A and D are correct statements: Site surveys (A) are a required first step before AP count calculations, since venue layout, materials, and obstructions affect AP placement. In high-density deployments (D), APs must be carefully spaced to minimize co-channel interference - closer APs with lower transmit power is the standard approach.

Memory tip: Think of a packed stadium - signal reaches everyone easily because APs are nearby, but thousands of users streaming video simultaneously is what kills performance. Dense people = capacity problem, not a coverage problem. If the exam presents this question, flag that B (coverage-limited) contradicts this principle.
