Companies transmit over the wireless LANs because WLANs ________.

• A. are inexpensive
• B. are secure
• C. Both A and B
• D. Neither A nor B

Answer: (B)

The reason companies use wireless LANs is that, when properly protected, they provide secure access for transmitting data. Wireless networks transmit over the air, which makes eavesdropping and tampering a real risk unless strong protections are in place. By employing robust encryption (such as WPA2/WPA3) and strong authentication (like 802.1X with EAP), access control, and centralized management, the data remains confidential and integral as it moves between devices and the network. That security framework is what justifies using WLANs for corporate communication, enabling mobility and flexible deployment without sacrificing protection. While cost and convenience are advantages, the security measures behind WLANs are the key reason they’re trusted for transmitting corporate information.
