Question 66 (practice exam 6) (additional)

  1. Question: How does IPv6 inherently enhance security compared to IPv4? Answer: IPv6 has IPSec built-in by default, offering end-to-end encryption and authentication, which is not a default feature of IPv4.

  2. Question: What is a significant difference between IPv4 and IPv6 in terms of addressing? Answer: IPv6 provides an extended address range, eliminating the need for network address translation (NAT) due to a vast number of available IP addresses, whereas IPv4 has a limited address space and often requires NAT.

  3. Question: Why is WPA2 considered more secure than WEP for WiFi networks? Answer: WPA2 uses stronger encryption methods (such as AES) and provides better security protocols, while WEP is outdated and has been proven to have many security vulnerabilities.

  4. Question: Does WPA2 include IPSec or extended IP address ranges as part of its protocol? Answer: No, WPA2 does not include IPSec or extended IP address ranges by default as it is a security protocol designed specifically for securing WiFi networks.

  5. Question: Why was WEP replaced by more advanced security protocols like WPA2? Answer: WEP was replaced due to its weak encryption algorithms that could be easily broken, leading to the development of WPA2 with more robust security measures.

  6. Question: How does the built-in nature of IPSec in IPv6 contribute to the security of a network? Answer: Having IPSec built into the IPv6 protocol ensures that security is an integral part of the network architecture, facilitating secure communications without the need for additional configuration.
