100-160 Question 91
Select 3A small business wants to secure its Wi-Fi network by allowing only specific devices to connect and ensuring that the data transmitted is encrypted. Which of the following actions should the business take to achieve this goal?
- A
Enable MAC address filtering on the wireless router.
- B
Set the Wi-Fi encryption standard to WPA3.
- C
Disable the SSID broadcast to hide the network.
- D
Use WEP encryption for backward compatibility.
- E
Create a strong and unique SSID name.
Show answer and explanation
Correct answers: A, B, E
Explanation
To secure the Wi-Fi network, MAC address filtering ensures only specific devices can connect, and WPA3 encryption secures the data. Additionally, creating a strong and unique SSID name helps distinguish the network while enhancing security. Disabling SSID broadcast and using WEP do not provide adequate or modern protection.
- A. Correct.
Enabling MAC address filtering allows the network to restrict access to specific devices based on their unique MAC addresses, increasing security.
- B. Correct.
WPA3 is the latest and most secure Wi-Fi encryption standard, ensuring that data transmitted over the network is encrypted and protected.
- C. Incorrect.
Disabling SSID broadcast does not directly secure the network; it only hides the network name, which does not prevent determined attackers from finding it.
- D. Incorrect.
WEP is an outdated encryption standard with significant vulnerabilities and should not be used for securing modern networks.
- E. Correct.
A strong, unique SSID name helps to avoid confusion with other networks and reduces the likelihood of unauthorized access attempts.
