CWT Security Protocols & Network Optimization

Question 1

What is the primary purpose of WPA3?

Accepted Answer

To enhance wireless encryption

Answer

WPA3 (Wi-Fi Protected Access 3) is the latest security standard for wireless networks, designed to address vulnerabilities found in previous protocols. Its primary purpose is to provide stronger encryption and more robust authentication methods, making it significantly harder for unauthorized users to compromise Wi-Fi traffic. This ensures greater privacy and security for all connected devices.

Question 2

Which feature helps isolate clients on a public Wi-Fi?

Accepted Answer

Client isolation

Answer

Client isolation is a security feature commonly used on public Wi-Fi networks. It prevents wireless clients connected to the same access point from directly communicating with each other. This isolates each user's device, protecting them from potential threats like malware propagation or data theft from other users on the same network.

Question 3

What is a common method to improve network performance?

Accepted Answer

Load balancing

Answer

Load balancing is a technique used to distribute network traffic efficiently across multiple servers, network links, or access points. By spreading the workload, it prevents any single component from becoming a bottleneck, thereby improving overall network performance, responsiveness, and reliability. This ensures that resources are utilized optimally and users experience faster speeds.

Question 4

What is the function of a firewall in a wireless network?

Accepted Answer

To filter and protect network traffic

Answer

A firewall acts as a security barrier in a wireless network, monitoring and controlling incoming and outgoing network traffic based on predefined security rules. Its function is to filter out malicious data, block unauthorized access attempts, and protect the network from various cyber threats. This ensures that only legitimate and safe traffic can pass through, safeguarding network resources and data.

Question 5

Which encryption standard is most secure for Wi-Fi?

Accepted Answer

AES

Answer

AES (Advanced Encryption Standard) is currently the strongest and most secure encryption standard widely used for Wi-Fi networks, particularly with WPA2 and WPA3 protocols. It employs robust cryptographic algorithms that are highly resistant to brute-force attacks and other forms of decryption. WEP and TKIP have known vulnerabilities, making AES the recommended choice for protecting wireless communications.
