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?
A.
Configure NAT on the firewall
B.
Implement a split horizon DNS
C.
Place the server in the DMZ
D.
Adjust the proper internal ACL
Explanation:
Why is the answer B?
Split horizon is the ability for a DNS-server to give a different answer to a query based on the source of the query. A common use-case is when using the same DNS-server for internal and external queries.
Not to be confused with just a split horizon which is a method of preventing a routing loop in a network.
