An administrator wants to host services on the internet using an internal server. The server is configured with an RFC1918 address, and the administrator wants to make the services that are hosted on the server available on one of the company's public IP addresses. Which of the following should the administrator configure to allow this access?
To make services hosted on an internal server with an RFC1918 address available on the internet using the company's public IP address, the administrator should configure a Virtual IP (VIP). A Virtual IP allows the internal server to be accessed through a public IP address while keeping the server itself on the internal network. This is often achieved through Network Address Translation (NAT) or port forwarding, which maps the external public IP address to the internal server's private IP address, ensuring seamless access from the internet.
Congrats if you saw all 817 questions to pass this exam! I took the exam today and all I can say is, these questions on this website are good. It's like 85~90% same (even answer orders are same). Trust people's opinions in discussion comments, not the original answers cuz there are lots of wrong answers. If you see a 50/50 debate on a question, just google it. You will get the real answer for the question. Good luck, bros.
I studied the 817 questions three times lol
i studied from 650 to 834 is that enough?
GPT answer seems legit. A, C, and D seem unrelated Using a Virtual IP (VIP) is a common approach to achieve this. A Virtual IP allows network services to be accessible through multiple IP addresses, including public IP addresses, without physically moving the server to a different network. Network Address Translation (NAT) or port forwarding can be used to map the public IP address to the internal server's RFC1918 address.
RFC1918 is referring to private IP. then you have to use public IP to use Private IP and Public IP simultaneously we will use Virtual IP Virtual IP cz for a single machine to represent multiple IP addresses on the same subnet
He should use Virtual IP address which is NAT service.
