Security Fundamentals

How does a firewall decide which traffic to block?

  • A The firewall matches traffic based on source and destination IP address.
  • B The firewall performs a one-to-many network address translation.
  • C The firewall performs a one-to-one network address translation.
  • D The firewall matches traffic based on the IP address in the ARP table.
Explanation

A firewall evaluates traffic against configured rules, commonly including its source and destination IP addresses. Network address translation changes address mappings but does not itself define which traffic is blocked, and ARP-table addresses are not the normal firewall rule-matching basis.
