From the Kali Linux virtual machine, which addresses does the lab instruct you to test for the DMZ web server?

Answer

http://10.xx.xx.253 and https://10.xx.xx.253

Explanation

### Why this is right The lab instructs students to open both the HTTP and HTTPS versions of the firewall's Internet-facing address from Kali. The NAT rules then forward those requests to the DMZ server. ### The concept The external client tests the address it can reach on the firewall's Internet-facing side. Destination NAT changes the request's destination to 172.16.10.10. Testing both protocols checks that both service mappings are configured. Replace `xx` with the network's assigned value, as the lab directs. ### The other options - **B. http://172.16.10.10 only**: this tests the DMZ server address directly, rather than the public-facing address through NAT, and omits HTTPS. - **C. http://10.xx.xx.253 and https://172.16.10.10**: it uses different destinations for the two tests instead of testing the firewall address for both. - **D. http://google.ca and https://google.ca**: those are Internet destinations, not the lab's DMZ web-server test. ### Terms - **Kali Linux**: The Linux virtual machine used as the external test client in the lab. - **HTTPS**: Hypertext Transfer Protocol Secure, a secure web protocol. ### Remember Test the external address for both protocols; the NAT rule supplies the internal server destination.
