I am completing practice questions based on Security+. I came across this one:

A security auditor discovers that a company has two firewalls of the same model protecting their internal network. What should the auditor recommend for their security architecture?

A. Change one of the firewalls to a different platform

B. Add a firewall of the same model

C. Only use one firewall

D. Remove firewalls in front of the internal network

Regardless of what the Security+ says, do you agree that A is the right answer?

I ask because just about every security professional I have ever met would say C is the right answer, so I am just gathering real-world opinions (while apparently still remembering answer A for the Security+ exam.)
