When a device receives a labeled packet, which of the following can occur?
When a device receives a labeled packet, it can decide whether to forward it as a labeled or unlabeled packet based on the received label value. MPLS (Multiprotocol Label Switching) technology uses labels to make data forwarding decisions without needing to examine the payload's destination IP address for each packet. This allows the labeled packet to be either forwarded to another MPLS domain or converted back to a standard IP packet for further routing. Thus, forwarding can be based on the label value.
Correct Answer: B 1.2 MPLS Overview When an MPLS device receives MPLS-encapsulated traffic, the device makes forwarding decisions based on the MPLS label value in the MPLS encapsulation header.
