Comment (0)
Suggested answer: D
Explanation:
Ingress filtering is a method used in network security to ensure that incoming packets are allowed or blocked based on a set of security rules.
This type of filtering is often implemented at the boundaries of networks to prevent unwanted or harmful traffic from entering a more secure internal network.
The term 'ingress' refers to traffic that is entering a network boundary, whereas 'egress' refers to traffic exiting a network.
