Question

In a SOHO wireless network, which of the following prevents unauthorized users from accessing confidential data?

A. Reduce broadcast power
B. Change SSID name
C. Set encryption
D. Enable MAC filtering

Answer 1

Encryption prevents unauthorized users from accessing confidential data in a SOHO wireless network.

Step-by-step explanation:

In a SOHO wireless network, the option that prevents unauthorized users from accessing confidential data is encryption. Encryption is the process of encoding information in such a way that only authorized parties can access it. It ensures that data transmitted over the network is secure and cannot be interpreted by unauthorized users. By using encryption protocols, such as WPA2 (Wi-Fi Protected Access 2), the data is encrypted and can only be decrypted by devices with the correct key.

Changing the SSID name (option B) can help make your network less visible to unauthorized users, but it does not provide direct protection for the data being transmitted. Similarly, reducing the broadcast power (option A) can reduce the range at which your network is accessible, but it does not prevent unauthorized users from accessing the network within that range.

While enabling MAC filtering (option D) can restrict access to authorized devices, it is not a foolproof method as MAC addresses can be spoofed or cloned. Encryption, on the other hand, provides strong security by encrypting the data itself and requires the correct encryption key for access.
