What specific problem does a WLAN resolve for corporations and home users?

• A. Excessive data cabling.
• B. Limited mobility within buildings.
• C. Inadequate security features in access points.
• D. High power consumption of wired networks.

Answer: (A)

Wireless LANs primarily address the lack of mobility inside a building. By removing the need to run a cable to every device, users can connect from anywhere within the wireless coverage area and move around while staying online. That roaming capability is the core benefit, making it the best fit for what WLANs solve.

While reducing the amount of cabling is a practical outcome of using wireless, the central problem addressed is not “being wired” but being able to connect and move freely within the space. The other options point to issues that are important in network design but not the fundamental problem WLANs solve: security features in access points are important, but WLANs don’t address security by themselves as the primary purpose; high power consumption of wired networks isn’t the main concern; and excessive cabling is a consequence of wired networks, not the primary problem wireless aims to fix.
