A technician just completed a new external website and setup access rules in the firewall. After some testing, only users outside the internal network can reach the
site. The website responds to a ping from the internal network and resolves the proper public address. Which of the following could the technician do to fix this issue
while causing internal users to route to the website using an internal address?
Configure NAT on the firewall
Implement a split horizon DNS
Place the server in the DMZ
Adjust the proper internal ACL
Split horizon DNS (also known as Split Brain DNS) is a mechanism for DNS servers to supply different DNS query results depending on the source of the request.
This can be done by hardware-based separation but is most commonly done in software.
In this question, we want external users to be able to access the website by using a public IP address. To do this, we would have an external facing DNS server
hosting a DNS zone for the website domain. For the internal users, we would have an internal facing DNS server hosting a DNS zone for the website domain. The
external DNS zone will resolve the website URL to an external public IP address. The internal DNS server will resolve the website URL to an internal private IP
