CompTIA A+ Core 2 (220-1202) — Question 88

Independent contractors often work from a business's lobby. Although the business has Wi-Fi. contractors often plug in their laptops to Ethernet ports in the lobby. Which of the following should a security engineer do to most efficiently address a potential security concern with this network setup?

Answer options

• A. Configure WPA3 encryption on the Wi-Fi router.
• B. Disable lobby ports and restrict external users to the guest wireless network.
• C. Use a protocol analyzer to check for malicious traffic on the network.
• D. Install signage telling external users not to use Ethernet ports.

Correct answer: B

Explanation

Disabling lobby ports and restricting external users to the guest wireless network is the most effective way to mitigate security risks, as it prevents unauthorized access to the internal network. Configuring WPA3 on the Wi-Fi router enhances wireless security but does not address the vulnerabilities posed by Ethernet connections. Using a protocol analyzer is reactive and does not proactively prevent unauthorized access, while signage alone does not enforce any security measures.
