2. A company is concerned about weak Wi-Fi security. Which method should the company use to increase Wi-Fi security?

Answer: A

Explanation:

Enable MAC address filtering to increase Wi-Fi security.

Implementing MAC address filtering allows the company to specify which devices can connect to the Wi-Fi network, thereby enhancing its security by limiting access to authorized devices only.

A) Enable MAC address filtering

This option is correct because MAC address filtering restricts network access to devices with specific MAC addresses, thus preventing unauthorized devices from connecting to the network. It adds an additional layer of security by ensuring that only pre-approved devices can communicate on the network.

B) Trust local hosts by default

This option is incorrect as trusting local hosts by default can lead to security vulnerabilities. It assumes that all devices within the local network are safe, which is not always the case. This could allow malicious devices to access network resources without proper checks.

C) Add more access points

This option is also incorrect because simply adding more access points does not inherently improve security. In fact, it could potentially expose the network to more vulnerabilities if not properly secured. More access points increase the surface area for potential attacks without implementing security measures.

D) Implement wired equivalent privacy (WEP)

This option is incorrect as WEP is considered an outdated and insecure protocol for Wi-Fi security. It has numerous vulnerabilities that can be easily exploited, thus failing to provide adequate protection for the network.

Conclusion

The most effective method for increasing Wi-Fi security is enabling MAC address filtering, as it directly restricts access to authorized devices. Other options either fail to improve security or introduce additional risks, reinforcing the need for robust access control measures in network security.
