Wireless Networking

Correct Answer: WPA3

The WPA3 protocol is the strongest wireless security protocol currently available and should be used for a new company-wide wireless network. The successor to WPA2, WPA3 provides robust protections against password-guessing attacks, offers increased cryptographic strength, and includes protocols for internet of things (IoT) devices. In contrast, WEP is an old and insecure protocol that can be easily hacked, and while WPA and WPA2 were improvements, they have known vulnerabilities and are less secure than WPA3.

Correct Answer: Enable roaming assistance.

The answer is 'Enable roaming assistance.' This feature helps to maintain a stable and consistent wireless network connection when moving between different access points. As an employee moves away from one access point and towards another, roaming assistance ensures that the device disconnects from the weaker access point and establishes a connection with the stronger one. This prevents unnecessary drops in connectionThe other answers are incorrect for the following reasons:- 'Use shorter encryption keys.' While shorter encryption keys can increase the speed of a wireless connection, they generally make the network less secure and do not address the problem of connection drops between access points- 'Change access points to different channels.' Having different channels can prevent interference between nearby access points. But it won't address sudden drops in connection when moving between different access points- 'Lower the maximum throughput on all access points.' Lowering the maximum throughput can reduce the overall speed of the network, and again, it does not solve the issue of dropped connections when transitioning between different access points.

Correct Answer: Change the wireless frequency of the company's access point.

In this scenario, the best mitigation step would be to change the wireless frequency of the company's access point. This is because the rogue access point nearby might be causing interference or a potential security threat. By changing the frequency, the access point signal may stop overlapping with the rogue one, thus possibly resolving the intermittent connectivity issue. Turning off the user's phone periodically wouldn't resolve the issue with the rogue access point. Purchasing a new wireless access point might not help either if the rogue access point is still operating in the same frequency. Requesting the ISP to change the wireless frequency might not immediately resolve the issue and it's usually not with their direct control. Therefore, changing the wireless frequency of the company's access point is the quickest and most straightforward solution.
