Which of the following descriptions about radio frequency resource management is correct? (Multiple choice)

Question

Options

• AThe propagation of wireless electromagnetic waves in the air will cause wireless signal attenuation
• BBy configuring radio frequency resource management, radio frequency resources can be
• CBy configuring radio frequency resource management, users can improve their online experience
• DBy configuring radio frequency resource management, the security of user access can be

• A
  79% (19)
• D
  21% (5)

Explanation

Options A, B, and C are correct because they accurately reflect how RF resource management functions in wireless networks. Wireless electromagnetic waves naturally experience signal attenuation as they travel through air (A) - this is a fundamental physics principle (free-space path loss) that RF management must account for. RF resource management tools such as automatic channel assignment, transmit power control, and load balancing allow administrators to optimize utilization of available radio frequency resources (B) and improve end-user experience (C) by reducing interference, balancing client loads, and maximizing coverage quality.

Option D is the distractor - RF resource management does not directly improve the security of user access. Security is handled by separate mechanisms such as authentication protocols (WPA2/WPA3, 802.1X/EAP) and encryption. Confusing resource management with security management is a common mistake.

Memory tip: Think of RF resource management as an "infrastructure optimizer" - it manages how signals are used (channels, power, load), not who is allowed to use them (that's security). The three correct answers all relate to signal quality and resource efficiency, while the wrong answer (D) crosses into a different domain entirely.
