A system administrator runs a network inventory scan every Friday at 10:00 am to track the progress of a large organization’s operating system upgrade of all
laptops. The system administrator discovers that some laptops are now only being reported as IP addresses. Which of the following options is MOST likely the
cause of this issue?

A.
HIDS
B.
Host-based firewalls rules
C.
All the laptops are currently turned off
D.
DNS outage
So tricky question. When you read question you think on D, DNS outage becouse laptops are IP address.
But I think that answer is correct B.
Laptops are not web servers with web domain names
