Which two methods are used to reduce the AP coverage area? (Choose two.)

Question

Options

• AIncrease minimum mandatory data rate
• BReduce AP transmit power
• CDisable 2.4 GHz and use only 5 GHz.
• DEnable Fastlane.
• EReduce channel width from 40 MHz to 20 MHz

• A
  90% (45)
• C
  6% (3)
• D
  2% (1)
• E
  2% (1)

Explanation

Reducing AP Coverage Area

Why A and B are correct: Increasing the minimum mandatory data rate forces clients to be closer to the AP to maintain the higher modulation required, effectively shrinking the usable coverage cell. Reducing AP transmit power directly lowers the signal strength radiated outward, physically decreasing the area where clients can associate with that AP - both are standard RF cell-sizing techniques used in high-density deployments.

Why the distractors are wrong: Option C (disabling 2.4 GHz) does limit range since 5 GHz doesn't travel as far, but this is not a primary method for reducing coverage area - it's a band management strategy with other implications. Option D (Fastlane) is a Cisco feature that prioritizes Apple device traffic using QoS and has no effect on coverage area. Option E (reducing channel width) affects throughput and interference but does not meaningfully shrink the AP's coverage footprint.

Memory Tip: Think of the two levers you directly control: "Turn it down, or speed it up" - turn down the power (B) or speed up the minimum rate requirement (A). Both force clients to stay closer to the AP, making the coverage cell smaller.
