What is the role of a firewall in an enterprise network?
A. determines which packets are allowed to cross from unsecured to secured networks
B. processes unauthorized packets and allows passage to less secure segments of the network
C. forwards packets based on stateless packet inspection
D. explicitly denies all packets from entering an administrative domain
Solution
Correct answer: A. determines which packets are allowed to cross from unsecured to secured networks.
A firewall's primary role in an enterprise network is to monitor and control incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet, determining which packets are allowed to pass through based on security policies.
