The IP packet traveling from the service provider toward the subscriber is called the:

• A. Ingr ess IP Packet
• B. Egress IP Packet
• C. Internet Breakout / Local Internet Breakout
• D. SD-WAN Edge function

Answer: (B)

When thinking about traffic flow between networks, the key idea is the direction relative to the network in question. Egress refers to traffic leaving a network toward another network, while ingress is traffic entering a network from outside. In this scenario, the packet is traveling from the service provider’s network toward the subscriber’s network, so it is exiting the provider’s network and entering the subscriber’s network. That makes it an egress IP packet.

The other terms don’t fit because ingress would be traffic moving in the opposite direction (from subscriber toward the provider). Internet Breakout / Local Internet Breakout describes where traffic goes to the internet, not the direction of travel between provider and subscriber. SD-WAN Edge function is a role within the network, not a descriptor of traffic direction.
