While testing a new host based firewall configuration a security administrator inadvertently blocks
access to localhost which causes problems with applications running on the host. Which of the
following addresses refer to localhost?
A.
::0
B.
127.0.0.0
C.
120.0.0.1
D.
127.0.0/8
E.
127::0.1
Explanation:
it is the loopback address 127.0.0.1
I would be happy to select 127.0.0.1, but there is no such an answer. The closest one is 120.0.0.1. I guess the test organizers did a type error here and really meant 127.
