In large corporate networks having supply partners across
the globe, network traffic may continue to rise. The
infrastructure components in such environments should be
scalable. Which of the following firewall architectures
limits future scalability?
A. Appliances
B. Operating system based
C. Host based
D. Demilitarized
Answer / guest
Answer: A
The software for appliances is embedded into chips.
Firmware-based firewall products cannot be moved to higher
capacity servers. Firewall software that sits on an
operating system always can be scalable due to the ability
to enhance the power of servers. Host-based firewalls
operate on top of the server operating system and can be
scalable. A demilitarized zone is a model of firewalls
implementation and is not a firewall architecture.
